How to read this: after the spring "10% risk" date, a 32°F frost happens in only about 1 year in 10. In fall, the "10% risk" date is the early end — a frost before it happens about 1 year in 10.

Frost data comes from NOAA station KISSIMMEE 2, FL (USC00084625), 1.9 mi (3.0 km) from the city center and 10 ft lower than the city center (-3 m). Record used for the 1991–2020 normals: 24 years.

Kissimmee gardening questions

When is the last frost in Kissimmee, FL?

Plan around Feb 6. At NOAA's Kissimmee 2, FL station, 1.9 mi from the city center, there is a 30% chance of a 32°F frost after that date. Half of springs have their last frost by Jan 28, and after Feb 25 the risk drops to about 1 in 10. A hard freeze (28°F) usually ends earlier, around Jan 16. Springs here are erratic: 56 days separate the 90% and 10% dates, versus a median of 36 days for cities on this site, so watch the forecast rather than the calendar.

When should I plant tomatoes in Kissimmee, FL?

Start seeds indoors Dec 12 – Dec 26 and set transplants outside Feb 13 – Feb 27, once nights stay above 50°F and the soil is near 60°F. With about 327 frost-free days, frost is not the main limit — fruit set drops when nights stay above about 75°F, so early plantings tend to do best. More: tomato planting dates by zone.

How long is the growing season in Kissimmee?

About 342 days without a 32°F frost in a typical (median) year. In 9 years out of 10 the season lasts at least 305 days, and in 1 year in 10 it runs 365 days or more. In fall there is a 10% chance of frost by Dec 17 and a 30% chance by Dec 30. That ranks 15th longest of 20 Florida cities on this site.

When should I plant a fall garden in Kissimmee?

Count back from the first fall frost (Dec 30): transplant broccoli Oct 7 – Oct 21; sow kale Oct 21 – Nov 18; sow lettuce Oct 21 – Nov 18; sow radishes Nov 18 – Dec 16. Hardy crops keep growing through light frosts; the median 28°F hard freeze here is Jan 12. How the math works: succession and fall planting.

Did Kissimmee's hardiness zone change on the 2023 map?

Yes. Most of Kissimmee was zone 9b on the 2012 map and is zone 10a on the 2023 map — half a zone warmer, like about 56% of U.S. ZIP codes. The shift comes from a newer 1991–2020 averaging period plus more weather stations and better mapping; it does not mean last frost comes earlier. Why the 2023 map is warmer.

How does Kissimmee compare with Orlando, FL?

Both are in zone 10a. The typical last spring frost in Kissimmee (Feb 6) comes about the same time as in Orlando, FL (Feb 4), 12 miles away, and the first fall frost is Dec 30 versus Jan 1. The two cities use different NOAA stations.
