Tampa, FL 33675 Frost Dates
Tampa, FL: when does the frost end?
Typically, the last spring freeze lands around 01/20, roughly 145 days out. Fall's first freeze usually shows up around 01/12, roughly 365 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Tampa 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 Tampa's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
How much risk comes with planting early here
01/20 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/10 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 12/27 and only about 1 year in 10 sees frost after that.
