The summer of 2023 was Earth’s hottest since global records began in 1880, according to an analysis by scientists at NASA’s Goddard Institute of Space Studies (GISS) in New York.

June, July, and August combined were 0.41 degrees Fahrenheit (0.23 degrees Celsius) warmer than any other summer in NASA’s record, and 2.1 degrees F (1.2 C) warmer than the average summer between 1951 and 1980. August alone was 2.2 F (1.2 C) warmer than the average. June through August is considered meteorological summer in the Northern Hemisphere.

This animated map shows monthly temperature anomalies (changes from an average) from summer 1880 to summer 2023 measured with respect to NASA's 1951-1980 baseline period.
