Frost risk by date in Woodlake

Half of springs at Lemon Cove, CA see their last 32°F night by February 5; only one in ten is past it by January 1, and one in ten still has one after March 20. Planting tender crops after February 23 leaves a 30% risk of a frost on them, after March 3 20%, and after March 20 10%. The 43 days between the even-odds date and the one-in-ten date is wider than at 91% 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 December 8 in half of years, as early as November 23 one year in ten, and holds off past January 8 one year in ten. A hard freeze of 28°F follows 14 days later, around December 22; in spring the one-in-ten date for 28°F is February 13, 35 days before the 32°F one. The freeze-free season lasts 307 days in a typical year, longer than at 68% of the 219 California stations; it reaches 347 days one year in ten and falls short of 262 one year in ten. On average 16 nights a year drop to 32°F or below. Nights of 36°F, when frost can still settle on leaves in low, open spots, continue 48 days longer, to about March 25, and return around November 23. A 24°F night is unusual: 10% of winters had one.
