is that the Cantabrian is also

During the month of June and especially in this transit towards July, the heat has monopolized all the prominence regarding meteorology. Heat in the environment and Heat in the waters of the Mediterranean. But high temperatures have not only affected these areas.

The Cantabrian, to the red red. The Eastern Cantabrian has also seen an alarming increase in surface water temperature. As explained The State Meteorology Agency (Aemet), on Monday the waters of this Atlantic region were at temperatures between 22º and 24º Celsius.

The thermal anomaly exceeded 3.5º in most of the Gulf of Bizkaia, with some areas located in thermal anomalies between 5º and 6.

In the case of the Eastern Cantabrian the situation is more complex. Although the coastal areas of western Asturias and Galicia have temperatures close to the average that the historical series offers to the dates we are in, as we enter the sea the anomaly is growing until approaching the barrier of 3.5º.

Heat not only affects the mainland. The month of June has been extremely warm, to the point of beating in the peninsula various temperature records, both in specific maximums and in averages. The average temperature of the first month of this summer was even higher the average temperature in months in principle warmer such as July or August.

The situation has affected a good part of Europe, especially to the south, but not only has it been reflected in continental temperatures but also in the maritime. In this sense, the Western Mediterranean has taken a large part of the attention: in mid -June the thermal anomaly reached 2.65º in this region with areas in the Balearic surroundings where it was between 3rd and 3.18º. On the 30th, according to Aemet dataDragonera Boya measurements were 30.55º, which implies areas with thermal anomalies higher than 5th.

The North Atlantic, another story. The Eastern Cantabrian has an important thermal anomaly that does not reproduce throughout the North Atlantic. While this region of the ocean has an anomally high surface temperature, the difference is not so extreme.

According to data from Climate Reanalizerthe thermal anomaly in the North Atlantic as a whole on the 30th was between 0.49º (if we take as reference the period between 1991 and 2020) and 0.67º (if we take as a reference the period between 1982 and 2010). The reason is, at least in part in the subpolar region of the North Atlantic, where the waters are colder than the historical average.

That is, a temperature greater than the historical averages but lower than the one we saw in the 2023 and 2024, when the temperature reached thermal anomalies of 1.14º and 1st respectively if we take as reference the period between 1982 and 2010.

The consequences of a hot sea. The importance of maritime or oceanic surface temperature should not be undervalued. Changes in this not only can affect marine ecosystems but also the continent.

The ocean occupies about two thirds of the earth’s surface and is in constant contact with the atmosphere: what happens in these waters affects the weather and the weather (and vice versa). This interaction is responsible for the heating of the tropical Atlantic serves as fuel to hurricanes in the Caribbean and North America, and is also the reason that a hot Mediterranean can cause worse cold drop events in the peninsular Levante.
