Bonita Springs, FL 34120 Frost Dates

Frost dates for Bonita Springs, FL, ZIP 34120

Zone 10a

Around 01/18 is the usual last spring frost, about 143 days away. The first fall frost typically arrives around 01/11, about 365 frost-free days later.

Zone 10a (30 to 35°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 Bonita Springs, not a forecast for this year.

What to do before the first frost

Zone 10a around Bonita Springs 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 01/18 isn't a guarantee

01/18 is the middle of 30 years of NOAA records, not a promise. Plant by 02/16 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.
