Seminole, FL 33777 Frost Dates
Seminole, FL: when does the frost end?
Typically, the last spring freeze lands around 01/17, roughly 142 days out. Fall's first freeze usually shows up around 01/14, roughly 365 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Seminole in Zone 10a (30 to 35°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 20 weeks until Seminole's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
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.
