In February 2025, land areas worldwide were +2.07 °C warmer than the 1901–1930 average, according to NASA's GISTEMP v4 analysis, compared with +2.47 °C in February 2024. That makes it the 6th warmest February in 146 years of records. The record for this month remains February 2016 (+2.70 °C).
From January to February, 2025 averages +2.31 °C — the 2nd warmest start to a year since 1880.
Over the 12 months ending in February 2025, the land average is +2.16 °C, against +2.03 °C over the previous 12 months. The highest 12-month average remains the one ending in August 2024 (+2.21 °C).
Every month since June 2023 has been more than 1.5 °C above the 1901–1930 average — 21 months in a row.
These figures cover land areas only. Land warms faster than the ocean, so the values are higher than the combined land-and-ocean averages usually quoted.

Sources and method
- Temperatures: NASA GISS, GISTEMP v4, monthly mean over land areas, rebased to 1901–1930 (file of November 14, 2026).
- Ranks use the months known at the date of the report. NASA slightly revises past values at each update, so figures can move by a few hundredths of a degree.
