Hawthorne, FL 32640 Frost Dates

Hawthorne, FL: when does the frost end?

Zone 9a

The last spring frost here typically falls around 03/01, about 185 days from today. Fall's first freeze usually shows up around 12/07, roughly 284 days after the last spring frost.

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

Stretching the season past the first frost

With roughly 14 weeks until Hawthorne's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.

Why 03/01 isn't a guarantee

03/01 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 01/29 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 03/22 and only about 1 year in 10 sees frost after that.
