March 2026 was globally the fourth-warmest on record

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

The bulletin reported that March 2026 was the fourth-warmest March globally, with an average surface air temperature of 13.94°C, which was 1.48 °C above the estimated pre-industrial level (1850–1900).

These data visualisations, based on C3S data, show surface air temperature anomalies across the Northern Hemisphere in March 2026, focusing on Europe, Africa, and the Americas. 

The map on the left shows warmer-than-average temperatures across the United States and Mexico, more than 7°C above the historical average. This contrasts with unusually cold conditions in Canada and Alaska, where temperatures reached -12°C. 

The map on the right shows warmer-than-average temperatures in north-eastern Europe, while slightly colder-than-average conditions are visible over southern Europe, Turkey, and most of Iceland. The Arctic faced warmer-than-average temperatures, reaching +12 °C.More information is available here.
