Tampa, FL 33603 Frost Dates

When can you plant in Tampa, FL?

Zone 10a

Around 01/20 is the usual last spring frost, about 145 days away. The first fall frost typically arrives around 01/12, about 365 frost-free days later.

Tampa sits in USDA Zone 10a (30 to 35°F average annual minimum). The dates above are NOAA's 1991-2020 normal at the nearest reporting station, a 30-year average, not a forecast.

What to do before the first frost

About 20 weeks of growing season left in Tampa before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 01/20 isn't a guarantee

01/20 is the middle of 30 years of NOAA records, not a promise. Plant by 02/10 and you're betting against frost in roughly 9 years out of 10. 12/27 is the safer bet, historically only a 1-in-10 chance of frost that late.
