Deconstruct SunHialeah, FL: Hardiness Zone 11a & Sunlight by Season
Hialeah is in USDA hardiness zone 11a. Here’s what that means for winter, plus sunrise, sunset, daylight hours and the sun’s path through the year.
Zone 11a in Hialeah
On the 2023 USDA Plant Hardiness Zone Map, Hialeah falls in zone 11a. That means the coldest night of a typical winter drops to between 40 and 45 °F. Perennials, shrubs and trees labeled for zone 11a 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.

What “full sun” means in Hialeah
Full sun is 6+ hours of direct sun. In Hialeah an open spot has 13.8 hours of daylight to work with in June and 10.5 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.
