Oldsmar, FL: when does the frost end?

Zone 10a

The last spring frost here typically falls around 01/20, about 145 days from today. Fall's first freeze usually shows up around 01/09, roughly 354 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 Oldsmar, not a forecast for this year.

Stretching the season past the first frost

With roughly 19 weeks until Oldsmar's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.

Why 01/20 isn't a guarantee

01/20 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/14 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.
