Fort Pierce, FL 34981 Frost Dates
Fort Pierce, FL: when does the frost end?
Around 01/24 is the usual last spring frost, about 149 days away. Fall's first freeze usually shows up around 01/14, roughly 365 days after the last spring frost.
Fort Pierce sits in USDA Zone 10a (30 to 35°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 20 weeks until Fort Pierce's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 01/24 isn't a guarantee
01/24 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 02/21 and only about 1 year in 10 sees frost after that.
