Seminole, FL 33779 Frost Dates

33779, near Seminole, FL: the frost window

Zone 10a

The last spring frost here typically falls around 01/17, about 142 days from today. Fall's first freeze usually shows up around 01/14, roughly 365 days after the last spring frost.

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 Seminole, not a forecast for this year.

Stretching the season past the first frost

Seminole's growing season runs out in roughly 20 weeks — a cold frame or greenhouse kit is the usual way to keep cool-weather crops going past the first frost.

Why 01/17 isn't a guarantee

01/17 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 01/01 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 02/06 and only about 1 year in 10 sees frost after that.
