Every summer Spain is more of an oven. This map of AEMET records demonstrates it station by station

Climate change is bringing increasingly hot summers and a rather hopeless consolation: increasingly it’s harder to remember a cool summer and the feeling that this torrid summer will be the coolest of our lives (this applies equally this summer to the previous one or next summer). And it’s not just sensations: there is data.

Without going any further and according to AEMET datathe Spanish state has just experienced the most extreme heat wave ever recorded in the month of June with some days, June 22 and 23, 2026, which were the warmest of that month in Spain since at least 1950. +7.1 °C above usual values. Faced with this reality, someone has thought of marking the maximums recorded by the Spanish State Meteorological Agency on a map that reveals that the frequency and severity with which the temperature breaks records happens more and more often. And if the pattern holds, this historic June could be, in a few years, just a normal June.

The dev and data analyst Adrian Maqueda has developed an interactive map from Spain showing each station in the AEMET network and the latest heat record that he has beaten. That there is a new record? (because unfortunately this summer it will surely happen again) Well, the map updates automatically. This system works with both maximum and minimum temperatures.

The updated reading data and historical records come from AEMET’s OpenData. From here the readings are crossed to, in case of a new record, indicate it. The more recent the milestone, the more striking the color and the older the color, the more subdued. In this way it is intuitive to detect the thermal records on the map with the naked eye. Of course, it is not the same for a centennial station to set a record as for one that is only a few years old to do so.

How hot it is (it doesn’t matter when you read this)

Spain, in maximum temperatures

Precisely what makes this map so valuable is how visual it is to verify that They are not isolated phenomena applicable to a specific areabut a pattern that covers the entire territory. And it happens more and more frequently: according to the Report on the State of the Climate in Spain 2025 According to AEMET, in Spain in the last decade 221 records for warm days have been broken and only 7 for cold days.

Seen with perspective, the average temperature in Spain has gone up 1.75 °C since 1961 and The 12 warmest years in the historical series are all from the 21st century. The widespread and sustained increase in temperatures has direct consequences for health. In fact, the heat already kills us more than the cold. This trend is not exclusive to Spain: according to the World Meteorological Organizationheat waves in Europe are becoming more frequent, more intense and extending to regions that barely suffered from them before. And be careful because Europe is also the continent that comes out worst off.

The Tama station (Cantabria) has just renewed its maximum

Returning to the map, last week’s heat wave meant renewing a few of those orange circles to set records because of the network of 828 AEMET stations, 13 new maximum temperature records were recorded. For example, it is the case from Tama station (Liébana), in Cantabria: it reached 43.7 degrees on June 23, the highest temperature recorded in that community in any month of the year. The days were an oven, but the nights became tropical: in southern cities like Jaén or Segovia, the nighttime minimums exceeded 28 degrees.
