Frost risk by date in Newman
Half of springs at Newman, CA see their last 32°F night by February 26; only one in ten is past it by January 18, and one in ten still has one after April 21. Planting tender crops after March 26 leaves a 30% risk of a frost on them, after April 9 20%, and after April 21 10%. The 54 days between the even-odds date and the one-in-ten date is the widest 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 29 in half of years, as early as November 12 one year in ten, and holds off past December 21 one year in ten. A hard freeze of 28°F follows 13 days later, around December 12; in spring the one-in-ten date for 28°F is March 31, 21 days before the 32°F one. The freeze-free season lasts 273 days in a typical year, shorter than at 53% of the 219 California stations; it reaches 318 days one year in ten and falls short of 220 one year in ten. On average 23 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 40 days longer, to about April 7, and return around November 14. A 24°F night is unusual: 42% of winters had one.
