Wet-bulb globe temperature (WBGT) is the heat measure that actually tracks danger to the body. Unlike the plain air temperature on your phone, it folds in humidity, wind, and direct sun: the factors that decide whether your sweat can still cool you. It’s the standard the military, athletic associations, and occupational-safety bodies use to call when outdoor activity is no longer safe.
That matters in Tallahassee because inland Panhandle heat and thick Gulf humidity give this capital some of Florida's most punishing summer heat-stress days. The number above is the live outdoor WBGT for the city right now; tap through to the live map to inspect any neighborhood, scrub the forecast hour by hour, and see the 7-day outlook.
How hot Tallahassee usually gets
Across 2015–2024, Tallahassee averaged a 89°F daily high in summer: 59th hottest of the 174 metros we track, and July is typically the warmest month.
Most of the heat here sits below the extremes: around 55 days a year top 90°F, and only about 1 reach 100°F.
Humidity is the real story: summer averages about 80%, so sweat evaporates poorly and heat stress runs well above what a 89°F afternoon suggests.
A bad day runs well past a normal one, with 104°F recorded against a 89°F summer average.

For school sports, FHSAA (Florida High School Athletic Association) publishes FHSAA 2026-27 Handbook, Policy 41: Exertional Heat Illness (per Fla. Stat. §1006.165) — practice index 41.8.3, which uses wet-bulb globe temperature. Florida’s activity zones appear beside the live reading in the app.
Heat in Tallahassee: common questions
How hot does it usually get in Tallahassee?
Across 2015–2024, Tallahassee averaged a 89°F daily high through summer, with about 55 days a year at or above 90°F and 1 at or above 100°F. July is typically the hottest month, and the hottest day in that sample reached 104°F. Figures are from ERA5 daily reanalysis.
When is the hottest time of year in Tallahassee?
July has the highest average daily high in Tallahassee. Humidity is the real story here: summer averages about 80%, so sweat evaporates poorly and heat stress runs well above what the temperature alone suggests. Use the forecast on this page to plan around the specific days that matter.
Does Florida have a heat policy for school sports?
FHSAA (Florida High School Athletic Association) publishes FHSAA 2026-27 Handbook, Policy 41: Exertional Heat Illness (per Fla. Stat. §1006.165) — practice index 41.8.3, which uses wet-bulb globe temperature. Florida’s activity zones appear beside the live reading in the app. Our WBGT is a modeled estimate rather than the on-site device reading a policy may call for, so check the association's own document for current requirements.
What is the WBGT in Tallahassee right now?
The reading at the top of this page is the current wet-bulb globe temperature for Tallahassee, Florida, computed from live weather by the Liljegren (2008) method and labeled with how recently it updated. For an exact reading at your own neighborhood, plus an hour-by-hour forecast, open the live map.
Why is WBGT more useful than the temperature for Tallahassee?
Air temperature ignores humidity, wind, and sun: the things that decide whether heat is dangerous. Tallahassee's climate (inland Panhandle heat and thick Gulf humidity give this capital some of Florida's most punishing summer heat-stress days.) is exactly why a single "feels-like" or thermometer reading can understate the real risk. WBGT captures all of it in one number.
When is heat most dangerous in Tallahassee?
July is the peak month in Tallahassee, and within a day heat stress is highest in the early-to-mid afternoon when sun load is greatest. About 55 days a year reach 90°F, so most of the risk sits in a handful of afternoons rather than across the whole season. Use the forecast on this page to find the window that works.
