The municipality of Vinebre, in the Ribera d’Ebre region, recorded the highest temperature of the 2026 summer in Catalonia, reaching 44.1°C on July 8th. This figure is part of a summer that has been confirmed as the hottest ever measured in the region, with widespread thermal anomaly and unprecedented heat persistence.
During the months of June, July, and August, a total of twenty days were recorded where at least one station from the Network of Automatic Meteorological Stations exceeded 40 degrees Celsius. This number represents the highest count of extreme heat episodes observed in a single summer to date.
Vinebre and Alcarràs experienced fourteen days above 40 degrees. Only the Lleida-la Femosa station recorded more days with extreme heat, with fifteen. July 8th was particularly intense in Terres de l’Ebre, with temperatures surpassing 42 degrees in several locations such as Aldover (42.3°C), Ascó (42.3°C), the reservoir of Riba-roja d’Ebre (42.2°C), and Benissanet (42°C).
The first half of the summer had already been classified as the hottest since 1950, with an average temperature 3.8 degrees Celsius above the usual climatic average.
The high temperatures were not limited to daytime hours. Several stations recorded tropical nights, defined by minimum temperatures that do not drop below 25 degrees Celsius. This phenomenon particularly affected coastal areas and the Ebro valley, with exceptional nocturnal readings in places like l’Alfacs, Buda Island, and the reservoir of Riba-roja d’Ebre. These high minimums hinder rest and bodily recovery.
The extreme heat was accompanied by a significant lack of rainfall. The Meteorological Service of Catalonia describes the summer as dry or very dry in much of the territory, with marked impact in Segrià, Montsià, Baix Ebre, and Pla d’Urgell. The only exception was the Camp de Tarragona, where intense rain episodes in August locally exceeded the summer climatic average for precipitation.
