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 Garland because a dense Dallas suburb where humid Gulf air meets North Texas heat, driving muggy triple-digit days that keep wet-bulb temperatures dangerously high.

How hot Garland usually gets
Across 2015–2024, Garland averaged a 92°F daily high in summer: 38th hottest of the 174 metros we track, and July is typically the warmest month.
Most of the heat here sits below the extremes: around 76 days a year top 90°F, and only about 8 reach 100°F.
Humidity is the real story: summer averages about 65%, so sweat evaporates poorly and heat stress runs well above what a 92°F afternoon suggests.
A bad day runs well past a normal one, with 108°F recorded against a 92°F summer average.

For school sports, UIL (University Interscholastic League) publishes UIL 2026-27 Heat Stress & Athletic Participation Required Plan, which uses wet-bulb globe temperature. Texas’s activity zones appear beside the live reading in the app.
Heat in Garland: common questions
How hot does it usually get in Garland?
Across 2015–2024, Garland averaged a 92°F daily high through summer, with about 76 days a year at or above 90°F and 8 at or above 100°F. July is typically the hottest month, and the hottest day in that sample reached 108°F. Figures are from ERA5 daily reanalysis.
When is the hottest time of year in Garland?
July has the highest average daily high in Garland. Humidity is the real story here: summer averages about 65%, 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 Texas have a heat policy for school sports?
UIL (University Interscholastic League) publishes UIL 2026-27 Heat Stress & Athletic Participation Required Plan, which uses wet-bulb globe temperature. Texas’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 Garland right now?
The reading at the top of this page is the current wet-bulb globe temperature for Garland, Texas, 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 Garland?
Air temperature ignores humidity, wind, and sun: the things that decide whether heat is dangerous. Garland's climate (a dense Dallas suburb where humid Gulf air meets North Texas heat, driving muggy triple-digit days that keep wet-bulb temperatures dangerously high.) 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 Garland?
July is the peak month in Garland, and within a day heat stress is highest in the early-to-mid afternoon when sun load is greatest. About 76 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.
