"It's the highest temperature on record": Aemet's shocking explanation of what happened in Spain in June

It is the highest temperature recorded in a month of June: the Mediterranean reached 26.10 °C, according to the State Meteorological Agency (Aemet) through its profile in X. This value, more than 2 °C above normal for the date, is typical of the beginning of August.

Aemet is clear: there's no precedent in June for an air mass as warm as the one that overflew Spain at the end of the month. They explain this by analyzing temperatures at an altitude of approximately 1,500 meters (850 hPa), which allows them to measure the thermal nature of air masses.

The situation hasn't been a one-off. For much of the month, global temperatures were the second warmest on record for June, behind only last year, 2024, already considered the warmest on record.

According to experts, the figure reached in the Mediterranean this June is very close to the annual maximum that typically occurs between late July and early August. All of this reveals a shift in seasonal temperature patterns .

The most worrying aspect, according to Aemet, is that temperatures in 2025 are remaining very close to last year's, which could make the extremely warm years we've been experiencing on the peninsula more frequent.

Aemet states that a warmer sea contributes to more unstable air masses and increases the number of tropical nights even before astronomical summer arrives.

Furthermore, the fact that June is breaking records that are typically broken in August raises questions about the duration and severity of heat waves yet to come in July and August.
