Tampa, FL 33587 Frost Dates
Tampa, FL: when does the frost end?

The actual range around Tampa's last frost
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.
