Last frost across Florida

The frost-free season runs from 237 days at Crestview Bob Sikes Airport to 288 days at Jacksonville.

At 99 stations a freezing night doesn't come every winter, so the dates there apply only to the years that have one.

At 37 stations, frost comes in fewer than 1 year in 10, too rarely for frost dates.

These are typical dates: in half of springs the last frost comes later. Each place's page, and each ZIP code lookup, also gives the late-year date, after which only 1 spring in 10 has a frost. That's the safer date for tender plants.

Hardiness zones in Florida

Florida's 1,432 ZIP codes in the USDA list fall in zones 8b to 11b: 8b (1 percent), 9a (19 percent), 9b (23 percent), 10a (31 percent), 10b (16 percent), 11a (10 percent) and 11b (1 percent). Compared with the 2012 map, 61 percent of them moved to a warmer half zone (4 by a full zone or more) and 39 percent stayed the same.

A hardiness zone is about the coldest night of winter, which decides which shrubs, trees and perennials survive. Frost dates are about spring and fall, which decide when to plant. You need both. Read more about what the zones mean and what changed in 2023.
