The study maps the entire country, setting the average values from 1991 to 2020 as the new reference period, which already reflects the impact of global warming. The average temperature in Catalonia over the last three decades has been 13.1 ºC, nine tenths higher than in the previous period (1960-1990).
“"The data it contains are key for planning."
This average shows great territorial variability. The area of Tortosa, in Baix Ebre, is the hottest spot with values exceeding 18 ºC, while the peaks of the Pyrenees remain below zero. Regarding extremes, the highest value recorded in the reference period was 43.8 ºC in Alcarràs, although in 2023 temperatures exceeded 45 degrees for the first time in Alt Empordà.
The Atlas also details precipitation, with an average of 680 liters per square meter, but with sharp differences. The Massís del Port is identified as the country's “pluviometric pole”. In contrast, the territory with semi-arid conditions (less than 400 liters/m²) is increasing, affecting regions such as Segrià, Pla d'Urgell, Noguera, Urgell, Garrigues, Segarra, Ribera d'Ebre and Terra Alta.
“"They serve to make political decisions in areas such as risk management, climate welfare, or agriculture."
