St. Petersburg, Florida planting calendar and frost dates

Frost dates in St. Petersburg

A 32°F night is rare here: it happens in about 35% of years, so median frost dates do not describe a typical year.

NOAA U.S. Climate Normals 1991-2020 for Tampa International Airport, 5.1 miles WNW of the city center. Low-lying and rural spots often frost later in spring and earlier in fall than airports and city centers.

What to plant each month in St. Petersburg

The main vegetable season runs from August through March. Cool-season crops go in September-February, and warm crops like tomatoes and peppers get two shots, August-September and January-February. Occasional freezes mean tender plants need protection in winter. From June to August the heat and rain limit planting to tropical and heat-tolerant crops.
