Deltona, FL 32764 Frost Dates
Deltona, 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 01/09, roughly 352 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Deltona in Zone 9b (25 to 30°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 19 weeks until Deltona'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 02/23 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 12/29 and only about 1 year in 10 sees frost after that.
