California frost dates

Across 332 NOAA climate stations in California, the median last spring frost (32°F) ranges from Jan 1 at Bodega 6 Wsw to Dec 31 at Van Nuys AP; the typical station sees its last frost around Feb 25 and its first fall frost around Dec 1.

“Median” dates have a 50% chance of a later spring frost or an earlier fall frost. “10% risk” dates are the safer choice for tender plants: only 1 year in 10 has frost beyond them. Source: NOAA NCEI 1991–2020 Climate Normals. Elevation matters: within a state, frost dates can differ by a month or more between valleys and hills.
