Spain's summer season of 2025 marks the highest temperatures experienced since 1961

Spain witnessed an unusually hot summer in 2025, with several records being broken and extreme weather conditions dominating the season.

The summer of 2025 has been declared the hottest on record, with an average temperature of 24.2°C. This surpasses the previous record set in 2024, tying August 2025 with the warmest month on record.

June and August 2025 stood out as the warmest ever recorded, with the average temperature in June reaching a staggering 23.7°C, making it the warmest June on record. Similarly, August 2025 averaged 25.0°C, another record-breaking figure.

The heatwave that swept across Spain in August 2025 was not only intense but also prolonged. The country experienced the third longest heatwave on record, with 16 consecutive days of abnormally high temperatures.

Several regions were significantly affected by the high temperatures. The Guadalquivir Valley, the Guadiana Valley, the Ebro Valley, the Region of Murcia, and the southern half of the Valencian Community were the most affected areas from June 1 to August 31.

During this period, the highest temperatures in Spain were recorded in Jerez de la Frontera (45.8°C), Morrón de la Frontera (45.2°C), Murcia (45.1°C), and Alcantarilla (45.0°C).

Heavy rains are expected in parts of the northern tip of the Peninsula and the Levante this week, providing some relief from the heat. However, the respite will be short-lived, as temperatures will be below normal for the time of year in the western Peninsula, while in the Mediterranean area, values could be above what is typically expected for the start of the meteorological autumn.

The unusually high temperatures in Spain during the summer of 2025 were closely monitored by the meteorologist and head of the State Meteorological Agency, Mar Gómez.

Unfortunately, the extreme weather conditions also led to a record-breaking year for forest fires. A total of 380,000 hectares of forest were burned in 2025, making it the year with the most burned forest surface on record. Most of the large fires occurred during the August heatwave in the northwest of the Peninsula.

As we move into autumn, Spain continues to grapple with the aftermath of the unprecedented heatwave of 2025. The country will undoubtedly be looking forward to cooler temperatures and rainfall to help restore its ecosystems and alleviate the ongoing challenges posed by climate change.
