Frost dates for Estero, FL, ZIP 33912

Zone 10b

Around 01/17 is the usual last spring frost, about 142 days away. The first fall frost typically arrives around 01/16, about 365 frost-free days later.

The USDA Plant Hardiness Zone Map puts Estero in Zone 10b (35 to 40°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

Zone 10b around Estero has about 20 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 01/17 isn't a guarantee

01/17 is the middle of 30 years of NOAA records, not a promise. Plant by 01/06 and you're betting against frost in roughly 9 years out of 10. 02/06 is the safer bet, historically only a 1-in-10 chance of frost that late.
