The Copernicus Climate Change Service (C3S) has published its latest monthly Climate Bulletin, focused on key climate trends in October 2024.

The bulletin reports that October 2024 was the second-warmest October on record globally, surpassed only by October 2023.

The month was 0.80°C warmer than the 1991-2020 October average, with an absolute surface air temperature of 15.25°C, and marked the fifteenth month within a 16-month period during which global average surface air temperatures exceeded 1.5°C above pre-industrial levels.

This data visualisation based on C3S data shows Europe, where October 2024 ranked as the fifth-warmest October on record, with average temperatures 1.23°C above the 1991-2020 monthly average.

Data from C3S is essential for monitoring trends in the global climate, ultimately supporting decisionmakers in creating and implementing climate strategies for the future.
