Gainesville, FL 32603 Frost Dates
Gainesville, FL: when does the frost end?
Typically, the last spring freeze lands around 03/03, roughly 187 days out. Fall's first freeze usually shows up around 12/02, roughly 277 days after the last spring frost.
Gainesville sits in USDA Zone 9a (20 to 25°F average annual minimum). The dates above are NOAA's 1991-2020 normal at the nearest reporting station, a 30-year average, not a forecast.
Stretching the season past the first frost
With roughly 14 weeks until Gainesville's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 03/03 isn't a guarantee
03/03 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/01 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 03/23 and only about 1 year in 10 sees frost after that.
