Alt Empordà, in Girona province, recorded 61 days of thermal stress in 2025, according to the Copernicus climate programme. The same year was confirmed as the third warmest on record globally.
Copernicus said global temperatures in 2025 were 1.47°C above pre-industrial levels. That was 0.13°C below 2024, which remains the warmest year in the series.
The report also said the period from 2023 to 2025 is the first time three consecutive years have averaged above 1.5°C. It linked the warming trend to the build-up of greenhouse gases and unusually high ocean temperatures.
The data, coordinated with international bodies including NASA, NOAA and the World Meteorological Organisation, also identified 2025 as the warmest year on record for Antarctica and the second warmest for the Arctic. More Catalonia news
For readers following the science behind these figures, the main source is the Copernicus Climate Change Service. The World Meteorological Organisation also publishes climate updates and global temperature reporting.
For local context, the figures matter because thermal stress affects daily life, public health and planning across Catalonia, including inland and coastal areas. They also add to the wider picture of how climate change is affecting the region.
