Which months are mildest at U C L A?
Every month's normal high in U C L A falls between 65°F and 85°F.
That is a measurement, not a recommendation: it counts the months whose normal afternoon high sits between 65°F and 85°F, where a light layer is enough by day.

Have recent years at U C L A been warmer than normal?
2025 averaged 64.0°F, 0.3°F below the 1991-2020 normal of 64.3°F. 2 of the 5 complete years since 2021 ran warmer than the normal.
| Year | Mean | Against normal | Precip. |
|---|---|---|---|
| 2021 | 64.8°F | +0.5°F | 14.58 |
| 2022 | 65.8°F | +1.5°F | 7.39 |
| 2023 | 63.2°F | −1.1°F | 39.52 |
| 2024 | 63.1°F | −1.2°F | 27.64 |
| 2025 | 64.0°F | −0.3°F | 21.51 |
Over 64 complete years from 1934 to 2025, the station's annual mean temperature rose at a fitted 5.8°F per century (+0.32°C per decade). A fitted rate summarizes the whole record; single years swing well above and below it.

How does U C L A's climate compare?
U C L A is warmer than 168 of the 219 places with their own NOAA record in California, and wetter than 122. Across the 7,247 U.S. stations with normals, its annual mean of 64.3°F is warmer than 86%.
In the Köppen classification computed from these normals, U C L A is Csb: temperate, dry-summer, warm summer. What the classes mean.

Which places near U C L A share this climate record?
2 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.
