Frost Dates for 32693 — Trenton, Florida

Half of springs at Usher Twr, FL see their last 32°F night by February 28; only one in ten is past it by January 31, and one in ten still has one after March 22. Planting tender crops after March 8 leaves a 30% risk of a frost on them, after March 14 20%, and after March 22 10%. The 22 days between the even-odds date and the one-in-ten date is narrower than at 66% of the 101 Florida stations behind this site's ZIP pages, so a fixed calendar date is a gamble here.

Nights of 24°F, cold enough to damage hardier plants, come in 64% of winters and 16°F in 3%.
