Jacksonville, FL 32202 Frost Dates

Frost dates for Jacksonville, FL, ZIP 32202

Zone 9b

Typically, the last spring freeze lands around 02/01, roughly 157 days out. The first fall frost typically arrives around 01/05, about 330 frost-free days later.

Zone 9b (25 to 30°F average annual minimum) comes from the USDA Plant Hardiness Zone Map; the frost dates above are the 1991-2020 normal at the nearest reporting NOAA station for Jacksonville, not a forecast for this year.

What to do before the first frost

Zone 9b around Jacksonville has about 19 weeks left before the first fall frost — that's the usual window to get a cold frame up if you want to keep harvesting past it.

Why 02/01 isn't a guarantee

02/01 is the middle of 30 years of NOAA records, not a promise. Plant by 03/03 and you're betting against frost in roughly 9 years out of 10. 12/31 is the safer bet, historically only a 1-in-10 chance of frost that late.
