Dunnellon, FL 34433 Frost Dates

When can you plant in Dunnellon, FL?

Zone 9a

Around 02/03 is the usual last spring frost, about 159 days away. The first fall frost typically arrives around 01/03, about 329 frost-free days later.

The USDA Plant Hardiness Zone Map puts Dunnellon in Zone 9a (20 to 25°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.

What to do before the first frost

About 18 weeks of growing season left in Dunnellon before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 02/03 isn't a guarantee

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