The average global temperature for September stood at 16.11°C—1.47°C higher than the pre-industrial baseline (1850–1900), before human activity began to significantly warm the climate.

“The situation remains unchanged, with persistently high temperatures on land and sea surfaces, reflecting the ongoing influence of greenhouse gas concentrations in the atmosphere,” said Samantha Burgess, a climate expert at Copernicus.

Hot Spots Across Europe and Beyond

Compared to measurements dating back to 1940, unusually high temperatures were observed in parts of Europe—particularly the Nordic countries, Eastern Europe, and from the Baltic states to the Balkans.
Beyond Europe, above-average heat extended to Canada, parts of Greenland, Siberia’s northwest coastline, and vast areas of Antarctica.

The Copernicus Climate Program

Copernicus, an EU scientific program, publishes monthly global climate reports. Its assessments are based on satellite data, ground observations, and climate models, covering the past 85 years. These regular updates help scientists track long-term temperature trends and shifts in global weather patterns.

Rainfall: A Tale of Extremes

While much of Europe saw heavy rainfall—particularly Scandinavia, Italy, Croatia, Spain, and along the eastern shores of the Black Sea—other regions faced severe dryness.

Countries across the Americas, including Canada, the United States, Mexico, Brazil, and Uruguay, recorded unusually dry conditions, as did parts of Russia in Asia and northern India.
