California Frost Dates

California has 373 NOAA weather stations with freeze records in the 1991–2020 climate normals. The typical last spring frost ranges from December 29 at Point Mugu Nf to June 14 at Jess Valley; at half the stations it has come by February 22. The first fall frost typically arrives between September 10 at Portola and February 1 at Hearst Castle, with a median of December 1.

The growing season between the typical frosts runs from 91 days at Portola to 365 days at Vista; 281 days at the median station.

At 32 stations, NOAA records too few freezes to give a date: frost is rare there. At 9 stations, a freeze is possible in any month.

Every station in California

Typical dates have a 50% chance of a frost after them in spring, and before them in fall; safer dates, 10%. A garden can differ from its nearest station, especially in a valley or on a hillside: see why your garden may differ.

Questions

When is the last frost in California?

It depends on where you are. The typical last spring frost at California's NOAA stations ranges from December 29 to June 14, and half of them have had it by February 22. Enter your ZIP code above for the station nearest you.

When is the first frost in California?

Typically between September 10 and February 1, depending on the station; the median is December 1. Plan fall crops back from your own station's date.

What do "typical" and "safer" mean?

With the typical (50%) last-frost date, half of years still have a frost after it. With the safer (10%) date, only one year in ten does. In fall it's the other way around: the safer date is the earlier one.
