The summer of 2025 is one of the two hottest in Spain on record, along with 2022, since 1961, with temperatures one or two degrees above normal, according to the State Meteorological Agency (AEMET), pending definitive data, as the meteorological autumn begins on 1 September, which is also expected to be warmer than normal. The summers of 2025 and 2022 exceed the ‘historic’ summer period of 2003 by more than half a degree. In terms of rainfall, this summer has seen less than usual, with three-quarters of the usual amount for an average summer, although there have been some episodes of significant storms, especially in July.
eltiempo.es indicates that the average temperature this summer was 24.7ºC compared to 24.6ºC in 2022, which is 2.1ºC above normal for the period 1991-2020 (24.6ºC). These data ‘show’ that we are not experiencing ‘the usual heat’. It also adds that it has been a dry summer. And it indicates that while in the northeast it has been ‘normal’ in many areas, in the south, centre and throughout the west, the summer has been slightly dry to very dry. In Vigo and Pontevedra, for example, there has been between 40% and 50% less rainfall than normal. Meanwhile, in Lugo, the anomaly is almost -65%, and in Molina de Aragón (Guadalajara) it reaches -59%.
However, the weather portal notes some specific exceptions, such as Granada, Jaén and Castellón. In the latter province, for example, rainfall has been 135% higher than normal. In contrast, the Canary Islands have also had a very dry summer, although it hardly ever rains there during the summer months.
By month, eltiempo.es highlights that last June was ‘record-breaking’, being the warmest on record, with an average temperature typical of July. Meanwhile, it points out that the first half of July was warm, and the second half was between normal and cold. Eltiempo.es explains that during that fortnight, ‘many people had the feeling that they had had a cool summer’. However, it notes that this was ‘a mirage’: August arrived and reminded us that this summer was ‘an intense one’.
Regarding the heatwave that lasted from 3 to 19 August, it recalls that it was the third longest recorded in Spain, as well as ‘the most intense’ since heatwave records began in the 1970s. It indicates that warm to extremely warm anomalies were the most frequent this summer and the most notable ones were concentrated in inland areas, the east and Galicia.
Some of the examples highlighted by the meteorological portal are Ourense, with an anomaly of 2.9ºC above the average temperature; Vigo and Pontevedra, which are 2.7ºC above, as are Soria and Lleida. Meanwhile, the areas with the lowest anomalies were in Andalusia, with ‘only’ 1.4ºC above average in Córdoba, 1.5ºC in Huelva and 1.8ºC in Seville. The anomalies were also noticeable during the day and at night, according to eltiempo.es. During the day, Granada tops the ranking with a deviation of 3.7ºC above normal for the summer of 2025 as a whole.
In the case of minimum temperatures, Barcelona takes first place, with 2.6ºC above normal values. As for the analysis of the distribution of average daily temperatures on the mainland, it points out that with a fixed set of stations with data from 1961 to 2025, 2025 is ‘far from normal’ in any previous period. As for the most likely trend for meteorological autumn, AEMET points out that it is likely to be a season with above-normal temperatures across the country. There is a 60-70% probability that this meteorological autumn will be warmer than normal, compared to a 10% probability that it will be colder on the mainland and the Balearics. With regard to the Canary Islands, these figures stand at a 50% probability that it will be warmer, compared to a 20% probability that autumn will be colder than normal.
With regard to rainfall, there is a 45% probability that autumn will be less rainy than normal in the west and centre of the mainland, as well as in the Canary Islands, compared to a 20% probability that rainfall will be higher than normal in these areas, while for the east of the peninsula and the Balearic Islands there is no clear trend.
On the other hand, AEMET highlights the passage of fronts in the coming days that will mainly affect the far north of Spain, with rain especially in Galicia that will extend to the Cantabrian communities and the Pyrenees. Storms will also form in the northeast and the Balearics. As the week progresses, anticyclonic weather is likely to prevail, with temperatures that will initially be ‘low for the season’, according to AEMET, but which will rise gradually and be high by the weekend. Temperatures could exceed 34ºC in the centre, south and east of the mainland, as well as in the Balearics.
