Aemet Confirms This June as the Hottest in 64 Years

Spain is sweltering under the heatwave, marking this month as the hottest June since records began in 1961, surpassing those of 2003 and 2017, which were tied. The State Meteorological Agency (Aemet) confirmed on Monday that June 2025 will be the hottest June in 64 years, with temperatures 3ºC higher than the average. It has exceeded the June months of 2003 and 2017, which were tied with an average of 22.8 degrees Celsius, with this month's average surpassing that figure, pending today's data.

The heatwave, which began last Saturday and continues into the start of the week, set a temperature record in Huelva, reaching 46ºC in El Granado. Additionally, it was the hottest Sunday across Spain since records began. Alconchel, in Badajoz, also nearly reached 45 degrees that day.

The heat has offered no respite at night, with minimum temperatures around 28 degrees in Cabo de Creus (Gerona) and Osuna (Seville), and a minimum of 29.7 degrees in San Bartolomé de Tirajana, Gran Canaria.

According to Aemet spokesperson Rubén del Campo, the intense heat will persist in much of Spain for the coming days, at least until Thursday, the 3rd. "There will only be significant temperature drops in the northern third, where maximums could be about 10 degrees lower on Wednesday than the previous day."

In the rest of the country, no major changes are expected, with thermometers above 36 degrees in large areas of the peninsula and Balearic Islands, and over 38 degrees in the northeast, centre, and south. In the Guadalquivir Valley and parts of the Guadiana, temperatures could even exceed 42ºC. "All this with very warm nights, tropical nights in many areas, even torrid, meaning minimums above 25 degrees in parts of the Mediterranean, centre, and south of the peninsula," specifies the spokesperson for the agency, under the Ministry of Ecological Transition (Miteco).

To the extreme heat, we must add the possibility of storm formation in northern and eastern parts of the peninsula these days. Especially in mountainous areas, these storms could be locally strong and accompanied by hail. In the second half of the week, uncertainty about temperatures increases. "A thermal drop is likely in the north, but intense heat could continue in the northeast, centre, south, and Balearic Islands," informs Del Campo.

For now, this Monday will see an increase in instability, leading to storm formation in mountainous areas and also in the central zone of the peninsula. Locally, they could be strong and accompanied by hail and intense wind gusts.

Meanwhile, intense heat continues across almost the entire peninsula and Balearic Islands, with no major changes in temperatures. Temperatures will exceed 40 degrees in the Ebro Valley and 42 in the Guadiana and Guadalquivir.

Tuesday, July 1st, will be a very similar day with generally unchanged temperatures. Very warm night, with minimums above 22 to 25ºC in the northeast, Mediterranean, Balearic Islands, centre, and south of the peninsula. Maximum temperatures will be slightly lower in parts of the Mediterranean, especially in Galicia and Asturias. Elsewhere, values similar to Monday, and therefore very intense heat.

Wednesday will see a notable drop in the northern third, except in Aragon and Catalonia, with values possibly 10 degrees lower than the previous day due to the arrival of northern winds and abundant cloudiness with rain in the Cantabrian communities. Bilbao, for example, will drop from 33 degrees on Tuesday to 24 degrees on Wednesday for maximum temperature. "Elsewhere, we will continue to experience a lot of heat both day and night, and attention should again be paid to storms on Wednesday," notes the Aemet spokesperson. These storms will particularly affect mountainous areas of the northern half and also around Castilla y León.

"Thursday will continue with this storm formation, which may be somewhat more frequent. Rain will continue for another day in the Cantabrian region, and as for temperatures, although there is more uncertainty, initially there will be no major changes, except for a rise in the north and a drop in western Andalusia. We will continue to exceed 36 degrees in the Balearic Islands, 38 in the northeast, centre, and south of the peninsula, and 40 to 42 in the Tajo, Guadiana, and Guadalquivir Valleys," details Del Campo.

Thursday night will continue to be hot, with minimums of 22 to 24 degrees in the Mediterranean, Balearic Islands, centre, and south. There could also be some torrid nights (above 25 degrees).

From Friday, uncertainty about temperatures increases further. "According to prediction models, a temperature drop is likely, more pronounced in the north and east. However, on Saturday, temperatures will still exceed 36 to 38 degrees in the northeast, southern Castilla y León, central zone, and also in the southern half with 38 to 40 degrees, even occasionally higher in the Guadiana and Guadalquivir Valleys," warns Del Campo.

In the Canary Islands, temperatures will drop on Monday and continue to fall on Tuesday, although by Wednesday they will rise again, with temperatures exceeding 30 or 32 degrees in the south of the islands and even above 35 in the south of Gran Canaria.

The most significant phenomenon in the archipelago during the first days of the week will be the wind, which will blow with very strong gusts on the southeast and northwest slopes of the islands, also causing rough seas.
