Frost Dates for 95954 — Magalia, California

Half of springs at De Sabla, CA see their last 32°F night by April 17; only one in ten is past it by March 23, and one in ten still has one after May 11. Planting tender crops after April 26 leaves a 30% risk of a frost on them, after May 1 20%, and after May 11 10%. The 24 days between the even-odds date and the one-in-ten date is narrower than at 74% of the 220 California stations behind this site's ZIP pages, so a fixed calendar date is a gamble here.

In fall the first 32°F night comes by November 11 in half of years, as early as October 21 one year in ten, and holds off past November 28 one year in ten.
