Has Los Angeles been warmer than normal lately?

2025 averaged 65.7°F, 0.1°F below the 1991-2020 normal of 65.8°F. 1 of the 5 complete years since 2021 ran warmer than the normal.

Over 98 complete years from 1909 to 2025, the station's annual mean temperature rose at a fitted 2.1°F per century (+0.11°C per decade). A fitted rate summarizes the whole record; single years swing well above and below it.

How does Los Angeles's climate compare?

Los Angeles is warmer than 192 of the other 218 places with their own NOAA record in California, and wetter than 96. Across the 7,247 U.S. stations with normals, its annual mean of 65.8°F is warmer than 90%.

In the Köppen classification computed from these normals, Los Angeles is BSh: hot semi-arid steppe. What the classes mean.

Which places near Los Angeles share this climate record?

11 places have no NOAA station with 1991-2020 normals of their own, and this station is the nearest full record. A place's own climate can differ from these figures, by several degrees where it sits much higher or lower than the station, nearer the coast, or inside a large city's heat; for the larger places the next nearest records are named with their yearly mean, so the spread around them is visible, and places of 50,000 or more have their own page with NOAA's gridded normals.
