Deconstruct SunTallahassee, FL: Hardiness Zone 9a & Sunlight by Season
Tallahassee is in USDA hardiness zone 9a. Here’s what that means for winter, plus sunrise, sunset, daylight hours and the sun’s path through the year.
Zone 9a in Tallahassee
On the 2023 USDA Plant Hardiness Zone Map, Tallahassee falls in zone 9a. That means the coldest night of a typical winter drops to between 20 and 25 °F. Perennials, shrubs and trees labeled for zone 9a or colder (a lower number) should survive the winter here.
A zone only covers winter cold. For a plant to do well it also needs the right amount of sun, and that varies far more from one corner of a yard to the next than the zone does across town.

Daylight through the year
What “full sun” means in Tallahassee
Full sun is 6+ hours of direct sun. In Tallahassee an open spot has 14.1 hours of daylight to work with in June and 10.2 in December, so a bed that clears 6 hours in summer can easily drop to part shade in winter once the low sun slips behind trees and houses.
