Fort Myers, FL 33913 Frost Dates
Fort Myers, FL: when does the frost end?
Around 01/17 is the usual last spring frost, about 142 days away. Fall's first freeze usually shows up around 01/16, 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 Fort Myers, not a forecast for this year.
Stretching the season past the first frost
With roughly 20 weeks until Fort Myers'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 01/06 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.
