temperatures

“Temperatures between 5 or 10 degrees above normal will continue,” says Rodríguez Marcos of AEMET.

by

We’ve known this for weeks. AEMET believes that the June-July-August quarter of 2026 will be in the warm tertile throughout Spain and the truth is that it is not a very risky bet. Of the 10 heat waves that AEMET has been counted in June in the Peninsula and the Balearic Islands since 1975half are concentrated in the last decade. The underlying problem is that, as we are seeing, June has ceased to be a ‘transition’ month to join (statistically and climatically) the summer ‘in a chemically pure state’. Like ‘June’ is ‘summer’? Climatologically it already was, of course. The climatic summer began on June 1. The difference is what the AEMET tells us: the same definition of heat waves was calibrated taking into account the highest temperatures of July and August. That it is increasingly common for June to begin to exceed these temperatures is a clear indication of what we are talking about. Above all, because the wave of June 2025 (from June 18 to July 4) It lasted 17 days and affected 40 provinces: the third longest and the third most extensive of the series. It’s not that this isn’t “the heat from before”, it’s that the situation is out of control. What does this translate into? As explained Francisco Javier Rodríguez Marcos of the AEMET, what the models say is that the temperatures this quarter will be among the 30 highest on record. This will especially affect the northern area, the east of the Peninsula and the Balearic Islands. The line to overcome is clear: the 46 ºC that El Granado (Huelva) reached on June 29 of last year. It is, so far, the highest temperature ever recorded in Spain in the month of June. But in 2026 isn’t that ‘weird’? It is true that we are coming from the wettest winter in 47 years, but it is also true that April was the warmest April in the historical series. That is, no one knows what is ‘normal’ in 2026 and, in this sense, no one can say that the scenario that is drawn is strange. The important thing is to prepare. In some ways, early waves have a potentially greater health impact because the body is not yet acclimated to the heat at the beginning of the season. In this sense, it is best to advance the preparation of the homes (insulation, cooling, night ventilation) and start preparing our daily lives.

If the question is whether AI data centers end up increasing temperatures in a region, the answer is: 2.2ºC

by

A group of researchers from Arizona State University have published a study striking. They wanted to estimate the impact of AI data centers on the average temperatures of the region in which they are installed. Their conclusion is disturbing, because this increase can be up to 2.2 ºC. The massive use of AI raises another problem. There is already a clear debate about the water and energy consumption of AI data centers, but this study has focused on an equally important problem: thermal pollution. It’s hot. The researchers focused on the Phoenix metropolitan area, the hottest in the entire US. There, their analyzes indicated that data centers expel air from their cooling systems at temperatures that are between 14 and 25 degrees Fahrenheit above ambient temperature, creating thermals that can affect nearby neighborhoods. The air says it all. This is the first known research to use high-precision vehicle-mounted sensors to compare air temperature before and after passing through the facility. The data was clear: Downwind areas of a data center had average temperatures 1.6ºF higher, with peaks of 4ºF (2.2ºC) compared to the reference areas. Heat island effect. The impact of this increase in temperature is also notable in terms of the distance affected: these increases were detected even 500 meters away from the source, which is equivalent to about five “blocks” of homes in the city of Phoenix. Vicious circle. The very design of data centers causes this problem to feed into itself. A single data center can generate as much waste heat as a small city of 40,000 homes, and the vicious cycle is clear: The data center blows very hot air to cool its servers The air warms the surrounding neighborhood Neighbors use their air conditioners more Air conditioners expel even more waste heat Location is the key. David Sailor, who led the study, indicated that what they seek with their conclusions is not to prohibit data centers, but to rethink their integration with urban centers. To avoid or mitigate problems, solutions are proposed such as reorienting air outlets or creating parks that cushion these increases in temperature. The key, these researchers say, is urban planning: these facilities must be treated as sources of industrial thermal emissions, because that is what they are. Prevent before cure. The projected computing capacity for data centers to be built in the US will double in 2030, which according to this study makes it necessary to take action. The challenge, they say, is to apply these solutions before the waste heat generated by data centers becomes a public health problem. Spain may also have that problem. Projects that affect our country should also take this circumstance into account. In recent months we have seen how the Autonomous Community of Aragón has focused part of the protagonism of agreements with large technology companies, and both Amazon and Microsoft have data centers planned in the metropolitan area of ​​the city of Zaragoza. The towns of Villamayor de Gállego and Villanueva de Gállego are less than 20 km from Zaragoza, and both already have data centers planned. These initiatives promise to boost the region’s economy, but they also bring doubts. Not everyone is in favor of such centers, of course, and there are even judicial processes trying to stop its construction.

Someone has looked at the temperatures under the Pacific and found a terrible forecast for next year

by

On September 1, 1513, on the verge of despair, Vasco Núñez de Balboa left Santa María de la Antigua in search of “a new sea rich in gold”. It took weeks and he lost dozens of men, but on the 29th of that same month he was the first known European to reach the shores of the South Sea. We still called him that. Seven years later, Magellan (emerging from that enormous and labyrinthine hell of canals, hurricane winds and storms that we call Tierra del Fuego) He called it Pacific and the name stuck. But there is nothing peaceful about it. That huge chunk of water concentrates most of the planet’s seismic and volcanic activity, generates the most violent typhoons, and is home to some of the most severe extratropical storms that exist. And I haven’t talked about El Niño yet. What about El Niño? We have been talking about the 2027 ENSO event for the past few days. We have always done it with quite a worrying tone and the truth is that, the more we know, the less exaggerated it seems to me: there are meteorologists who already describe the subsurface heat of the equatorial Pacific as “possibly the blob of warm anomalies ever recorded since we know how to measure these things“. And, as I say, it is not an informative “outburst”: the heat that is moving eastward beneath the tropical Pacific is (in volume and intensity) comparable to or greater than that which preceded the great Children of 1997-98 and 2015-16. What’s more, that heat is moving across a planet that is already 1.4 degrees above the pre-industrial level. Why are we getting nervous? This, I think, is the central question. First of all because what is invisible matters more than what we can see. In fact, “what we can see” (what we can measure on the surface of the ocean) is simply a trailer for what we are going to see in the coming months. It is true that the mechanisms that allow coupling between the ocean and the atmosphere are always mysterious and the uncertainty is great. However, as we move out of spring (the time that most “confuses” the models) the quality of our data increases. The problem is that, these new data, They only corroborate (little by little) our first intuitions. Of course, caution is necessary. Both ECMWF and NOAA they ask for caution and yes, it is important to be cautious. In one month, the scenario of having a Child before summer has suddenly become very likely and this growth in probabilities has left us all out of the loop. The public conversation, as a consequence, is getting out of control. But in reality, we are in completely uncharted territory. The problem with being unprecedented is that we grope in the dark. If we move forward. Today, there is only one clear idea: as in the 19th century, what happens will depend on the decisions we make.

A photographer endured temperatures of -28º and 4,000 m altitude in the Alps to capture an almost impossible image

by

“There are experiences that you plan for months and yet they arrive without you being prepared.” The phrase is from Angel Fuxa photographer specializing in astrophotography and night landscape portraits, and although it may sound a bit transcendental in your mouth it has a special meaning. A few weeks ago Fux ascended to a summit of 4,200 meters above sea level and, in the middle of hellish conditions which included temperatures of -28ºC, strong gusts of wind and icy ledges where a wrong step could be fatal, obtained one of the most impressive images of the year. Even has attracted attention from NASA. Photographing the darkness. Angel Fux (Paris, 1998) is not just a talented photographer. Over time he has specialized in a fascinating branch: astrophotography and portraits of night mountain landscapes. That obsession has taken her to the Alps, Andes, Pyrenees or the Dolomites, among other regions. “My search for dark skies has intensified over the years in a way that I did not understand until recently,” recognize on his blog. Some time ago Fux was fascinated by the darkness in the Peruvian Andes and in 2025 she ascended to Gornergrat (Pennine Alps) to enjoy a similar experience with your camera at 3,000 meters above sea level. From each expedition he returned to his studio with hypnotic photographs that fueled his ambition, so a few months ago he asked himself a question: Why not go further and observe the night sky from almost 4,200 m above sea level? Dent d´Hérensa summit located just behind the Matterhorn, between Italy and Switzerland? Double arch captured in 2025 in Gornergrat. Image: Angel Fux A very precise objective. His idea was not only to ascend the Dent d’Hérens and aim his objective at the night sky. Fux wanted to capture a unique and ephemeral spectacle: the moment in which, with the help of a prepared camera, an astrophotographer can capture the double arc of the Milky Way. “Once a year, in the northern hemisphere, something simply extraordinary happens in the night sky. For a few days each March it is possible to see both arms of the Milky Way above the horizon on the same night, not at the same time, but along the same Earth’s rotation.” “The winter arc, a quieter, less dense band of stars, rises during the first half of the night. Then, as the Earth rotates, the summer arc rises from the other direction, bringing with it the galactic core, that unmistakable, dense river of light. Together, they form what is known as the double arc of the Milky Way.” It is not an unexplored phenomenon. Other photographers have captured it in awesome images and Fux herself portrayed the double arch in 2025 from the Gornergrat, at 3,100 m. Photographers with ice axes. The challenge that Fux set for himself this year raised the bar for several reasons. To begin with, the area in which I wanted to work. It was proposed to ascend 1,000 meters more than in 2025, until the Dent d’Hérensto achieve a unique result. The reason? “Photographers don’t go there, especially in winter and even less at night. The equipment necessary for astrophotography and that required for mountaineering are simply incompatible in most cases,” relates. For his expedition he needed the help of a professional mountain guide, Richard Lehner, who participated in the project with his son, Arnaud. Squaring the circle. Another complication is that, although the natural spectacle that Fux was looking for is repeated every year, it is not always photographable. For the cameras to capture it properly, they must be other extra conditions: the right phase of the moon, a correct location for the angle of the arcs, a 360-degree clear horizon and as low a level of light pollution as possible. Even if the photographer takes care of all these factors in detail and looks for the most suitable location, there is a risk that the weather will not be good. If so, the job is in danger because, as Fux remembersthe “optimal period” to take the image is very limited: it lasts just five days, so there are years in which the spectacle simply “disappears.” Months of preparation. In your blog Fux explains in detail what the preparation process was like, but comes with knowing two pieces of information. Although the photo was taken in March, he contacted his guide half a year in advance, in September. During those six months Fux dedicated himself to planning logistics, preparing the equipment and studying how to approach the work. However, it is one thing to have a plan drawn up and quite another to have it fulfilled. Throughout the process, the Frenchwoman faced several setbacks that did not prevent her from heading to Dent d’Hérens in March with Richard and Arnaud. The three knew that there was a risk that their stay at the summit would be complicated, so they had to be well equipped. Biggest fear: frostbite. “My sleeping bag is designed to withstand temperatures down to -30ºC, with a survival threshold that extends to -50 or -60ºC. My boots are three-layer mountaineering boots, with attachable crampons. My clothing consisted of several layers, both to maintain passive heat and allow active movement,” clarify. “We also had a system of ropes and harnesses prepared, since once at the top, I had to be tied at all times when leaving the tent. The ledges that surrounded the area made any movement without a rope very dangerous.” And the technical part? fux usa a special team which includes, among other pieces, a Nikon Z6 II camera adapted for astrophotography, a Nikon NIKKOR Z 20mm f/1.8 lens and a Benro Polaris star tracker. Despite this material and his experience in the mountains, Fux had to deal with some unforeseen events that threatened to ruin the project. For example, the nights spent acclimatizing to the altitude practiced with the camera to make sure, among other things, that you could handle it with gloves. “During one … Read more

Spain will go from -14ºC to warmer temperatures in days

by

It’s not just a feeling when you go out this morning: Winter has decided to enter through the front door at the beginning of this year 2026. After a few years of warmer patterns, the current atmospheric configuration has opened a direct corridor from the Arctic to the peninsula that has undoubtedly left many of us frozen. The temperatures. Throughout all of Spain we have been able to see really low temperaturessuch as Madrid, which woke up today at -2 °C, but the capital is almost a thermal oasis compared to the rest of the country. In Burgos, the wind has plummeted the thermal sensations down to -13 °C, and in the “proverbial” cold area of ​​Molina de Aragón (Guadalajara), the thermometer has reached -14 °C. We are facing an episode of extreme cold that has put half of Spain on yellow, orange or even red alert. What is happening. What we are experiencing is not an isolated event, but the result of a meteorological coincidence. The key is in an anticyclonic block located in northern Europe, which is a wall of high pressure that has forced air masses to circulate along its southern flank, channeling polar and continental air directly towards our latitudes. to this The storm Francis has joined itwhich has left significant rainfall and snowfall throughout Spain. Its position has acted as a suction pump, facilitating the entry of this mass of arctic air and causing not only the collapse of thermometers, but also snowfall at unusually low levels. A thermal ‘scooper’. The AEMET had to activate the red notice in the Parameras de Molina, a landmark that is not seen every winter. Some of the most notable temperatures that we have detected, for example, are the following: Molina de Aragón (Guadalajara): -14 °C. Burgos: wind chill of -13 °C due to the combination of frost and wind. Madrid (Retiro/Barajas): -2 °C, with minimums in the periphery, such as in Alcalá de Henares, dropping to -6.7 °C. Sierra Nevada: extreme minimums of up to -17 °C. How long is it going to last? The truth is that the intense cold will continue throughout the day, as it did during the early hours of January 7th. This makes the red notices in Guadalajara and orange in the northern interior They will remain active until mid-morning. But starting January 8, the Arctic air mass will begin to withdraw from the peninsula, making the weekend much milder than the previous one. In fact, forecasts indicate that by the weekend we could go from one extreme to the other, with temperatures 1 to 3 °C above average for this time of year. This will take us from ice to ‘almost hot’ in a matter of days with maximums of around 16 °C on Tuesday, January 13. A new storm. Beyond the temperatures, we must keep in mind that between January 8 and 9, Storm Goretti will form, and that it will also experience explosive cyclogenesis, as the AEMET points out. Its impact will be mainly in the central European countries and in Spain its impact will be less, although it will temporarily generate maritime wind or rain in the north.

“Maximum extraordinarily high temperatures for this time”

by

After one of the hottest summers that are rememberedthe arrival of Dynamics of meteorological autumn It was literally a “fresh air breath.” Therefore, many have begun to ask ourselves if we could take the summer dead, start getting the bedspreads and keeping the controls of the air conditioners. And for our tranquility, Aemet He has just responded To our questions: or by chance. As? To be precise, what Aemet tells us is that “the temperatures planned at about 1500 m altitude will become higher in the next few days than any record of the 1991-2020 reference period for these dates.” That is, everything seems to indicate that “the mass of air on Spain will be extraordinarily warm.” Since approximately, on September 10, temperatures have been rising throughout Spain. As they pointed out at the time“We will talk about a clearly summery environment, with August temperatures.” And, although the worst forecasts were not fulfilled, “of the 30 degrees They will not go down in a few days. ” We can’t say it’s a surprise … Although it has been A rare year at the weather level (As already We have discovered in the worst possible way) There is something that we have learned over the last years and that we should not forget: heat every time comes before (“Between three and four weeks In almost the whole country “) and leaves later. With the only exception of the city of Alicante, summer It has lengthened in each and every of the provincial capitals of the country. In some more than a month. And that, of course, has its most direct correlation in medium temperatures well above of what was normal in the previous decades. However, it is a surprise. If the forecasts are fulfilled, in many areas of the country the days They will be surprisingly warm For these dates of the year. And not, We are not talking about the “Veranillo de San Miguel”. Unless we are willing to recognize that what we have been calling for years is nothing more than a way to normalize that is getting hotter. What can we expect? In principle, from Monday to Friday We can expect A “full summer environment with extraordinarily high temperatures for this time.” The only exception will be the Peninsular Northeast, which will contain the climb thanks to some more than probable showers during Monday and Tuesday. The good news is that the arrival of the weekend It will bring one “Notable temperature drops” (and some rains) throughout the peninsular north. That will be noted in the rest of the country. What will happen later? It is not very clear, but The spring of 2025 insisted in being different from the others, for now nothing suggests that autumn Go to follow that same path.

We had been waiting for temperatures down weeks. Once again a price has come: hail

by

The forecasts indicated that the worst Effects of the Paso de la Vaguada They would make themselves feel between yesterday afternoon and today. Forecasts that seem to be fulfilled, with abundant rainfall and located floods. However, if something has stood out on social networks of the first hours of the arrival of the storms, it has been the large hail that has been collected in some areas. Barcelona, in the center of the storm. The province of Barcelona has been the area where the passage of the trough that since yesterday sweeps the Mediterranean basin has been noticed, leaving in its path important stormy episodes with rain, hail and wind. Yesterday, the State Meteorology Agency (AEMET) He issued a notice Red for extreme risk in the area of central depression of Barcelona. The Aemet data Today show the effects of these stormy episodes in the province: as the 50 mm of rainfall collected yesterday in Prats de Lluçanès, or the 49.6 mm of Caldes de Montbui. At 11:00 today had already been collected 42.2 mm in the town of Vilafranca del Penedès. Hails. However, it has not been the amount of water that has caught the attention of the areas through which the storms have passed, but the hail. Its size, to be more concrete: they have gathered Pedriscos up to five centimeters. Cold trough, hot Mediterranean. The passage of the trough, an anomally deep trough for this time of year, has been the trigger for this situation, but to get here they have had to coaligate different factors. Factors such as Levante’s wind, loaded with moisture, which intermingle with the cold air of the trough, or as the surface temperature of the Mediterranean Sea, still high after several weeks several degrees above what would correspond. This situation has given rise to the appearance of the convective systems responsible for storms and rainfall seen in recent hours. Also of those we will see in the next. Still active warnings. The red notice activated yesterday inside Barcelona is no longer active, but Aemet keeps active A series of notices, including orange notices due to important risk, associated with rains and storms. Active notices affect much of the southeast quadrant of the Peninsula, in addition to the Balearic Islands and areas of the Catalan Pyrenees. The orange notices They concentrate today in the west of Castilla-La Mancha and the interior of the Region of Murcia. Active notices for tomorrow also include orange warnings due to rains and storms that will affect the Region of Murcia. They will be accompanied by yellow notices in a broader region in the southeast of the Peninsula, Catalonia, also the Balearic Islands. Attentive to evolution. The situation will improve only progressively. Some notices Aemet meteorlogics will still be kept active during Saturday in Catalonia, where rainfall is expected to reach 20 mm in an hour. Temperatures however will go up during the day, especially in the opposite area of the Iberian Peninsula: The forecasts The agency advances temperatures above 36º degrees in low areas of the southwest peninsular.

Aemet emits the first orange warnings by extreme temperatures

by

A few days ago, meteorologists They foresee that the worst of the warm episode that affects the Iberian Peninsula would come from Wednesday. Well, we are on Thursday and the forecasts become facts: the “Iberian oven” has activated and with it preventive measures. Orange warnings. Heat has led to the State Meteorology Agency to issue A series of yellow and orange notices by maximum temperatures. Today’s notices will affect seven autonomous communities, tomorrow Friday to nine. The Sevillian countryside will be the most affected area, where notices will be oranges due to maximum temperatures of 40º Celsius. Oven ignition. The obvious question is what is happening for the sudden arrival of more typical temperatures of summer than at the end of May. The answer can be found in the phenomenon known as “Iberian oven” As details Marta Almarcha in eltiempo.esthe phenomenon begins with the appearance of a dorsal in middle and high layers, that is, in the prolongation of a high -pressure center. This implies atmospheric stability and air -descendant movements that compress and heat the air mass over our own heads. More than an anticyclone. Anticyclonic and stable time also contributes to a High insolation which in turn also implies heat. As if this were not enough, Aemet warned a few days ago of the irruption of a Dana located between the Canary Islands and the Gulf of Cádiz that since yesterday pushes warm, dry and with dust in suspension to the peninsular south. Heat, very heat. The result, the one that is well palpating: heat. According to them Aemet forecaststoday maximum “high temperatures are expected for the time in most of the Peninsula”, with areas of the South exceeding the 34º-36º and with the possibility of exceeding 38º-40º in the Guadalquivir and Guadiana Extremadura. The story will be similar tomorrow Friday, with high maxims, possibility of exceeding 34º-36º degrees in the southern Atlantic aspect and the 38º-40º in the Guadalquivir, but without ruling out that the thermometers also reach this temperature at points of the Guadiana and depressions of the northeast. On Saturday a similar situation will be repeated as far as the maxims are concerned. Tropical nights. In addition to the maximum, the minimum temperatures also concern many. The fact that night temperatures They are not going to get off the 20th In some areas the dream of many will make it difficult. This is the phenomenon known as “tropical nights.” Spring activation. It is not the first time that we see this “Iberian oven” be activated in the middle of spring. In 2023 without going any further We were talking of its possible activation at the end of April.

The temperatures of the equatorial Pacific have collapsed in two weeks. The mystery is if the girl is behind

by

In the last two weeks, sea surface temperatures in the Eastern Tropical Pacific They have dropped abruptly Up to 10 degrees. As Ryan Maue saysIt is a fantastic example of how much the situation can change in a very short time. But is it something else …? … is the girl back? That is the great question that meteorologists, agencies and states of half the world are asked. And the first thing is to be clear that it does not have to mean Nothing crucial: “The layer near the surface is very susceptible to the changes caused by the wind due to its fine thickness.” This is important because, since March 2025, Enso conditions are neutral and (at least, In the last NOAA report on April 10) It was expected to continue until after summer. For October, the chances of remains the net scenario are 50%. The boy, the girl and everything in the middle. It is worth remembering that what we know as The southern child -scilation (or Enso, for its acronym in English) is a cyclic climate phenomenon (although somewhat irregular) that has great effects on the world climate. If we discount the stations, it is the largest source of annual climatic variations on the planet. The oscillation is A climate pattern in which two phases alternate: The boy and the girl. This phenomenon is manifested in a strip of the Equatorial Pacific, in the central and eastern areas. In this area, the oceanic surface temperature presents this oscillatory pattern between the warm phase (the boy) and the cold phase (the girl). How does it affect us? The ocean temperature in this region is associated with unique weather patterns that especially affect South America. In the southeast of the American continent temperatures become warmer than normal. In the same way, they become colder in the northeast. In Ecuador and Peru, less rainfall is expected than normal and the northeastern Brazil, torrential rains But teleconexions affect meteorological patterns around the world. And in Spain it is usually synonymous with less rains. But what worries meteorological ones is something else. We must not forget that the girl at the end of 2024 and early 2025 was A surprisingly very soft and short phenomenon. Although this phenomenon is “the great refrigerator of the world” (and thus has worked on other occasions), January was the warmest January of the registry. Its effect was noticed very little. And if we take into account that the 2023-2024 child was The fifth strongest Since we have records, it seemed to insinuate that Enso could be moving towards a structure much warmer What we are accustomed to. But … what does this mean? It is true that the models showed that there are almost twice the chances of the girl returningbut at this point in the cycle nobody knows what can lead to the long term. Anyway, most likely the neutral scenario endures more time. However, we must start thinking that the girl is just around the corner.
