Frost risk by date in Bell
Half of springs at Bell 4NW, FL see their last 32°F night by March 14; only one in ten is past it by February 18, and one in ten still has one after April 2. Planting tender crops after March 23 leaves a 30% risk of a frost on them, after March 28 20%, and after April 2 10%. The 19 days between the even-odds date and the one-in-ten date is narrower than at 88% of the 101 Florida stations behind this site's ZIP pages.
In fall the first 32°F night comes by November 22 in half of years, as early as November 4 one year in ten, and holds off past December 16 one year in ten. A hard freeze of 28°F follows 14 days later, around December 6; in spring the one-in-ten date for 28°F is March 22, 11 days before the 32°F one. The freeze-free season lasts 254 days in a typical year, shorter than at 94% of the 102 Florida stations; it reaches 290 days one year in ten and falls short of 226 one year in ten.

Nights of 24°F, cold enough to damage hardier plants, come in 89% of winters and 16°F in 20%.
