April 2026 was one of the warmest months of April globally

The Copernicus Climate Change Service (C3S) has published its latest monthly Climate Bulletin, focusing on key climate trends in April 2026.

The bulletin reports that April 2026 was the joint third-warmest April globally, tied with April 2016 and April 2020 with differences of less than 0.01°C. The average surface air temperature was 14.89°C, which is 1.43°C above the estimated pre-industrial level (1850–1900).

This data visualisation, based on C3S data, shows surface air temperature anomalies across the Northern Hemisphere in April 2026. The map reveals sharp regional contrasts across Europe, with warmer-than-average conditions over south-western Europe, reaching +4°C in the Iberian Peninsula, France, and Italy, while colder-than-average conditions are visible across much of eastern Europe, reaching -2°C in northern Poland.

C3S provides open and free access to climate data, supporting evidence-based policy, climate adaptation planning, and environmental monitoring globally.
