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 Laredo because one of the hottest cities in the country, this South Texas border town routinely tops 105F with brutal sun that pushes heat exposure to extreme levels. 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 Laredo usually gets
Across 2015–2024, Laredo averaged a 99°F daily high in summer: 16th hottest of the 174 metros we track, and July is typically the warmest month.
July is the hard part of a long season: roughly 59 days a year pass 100°F, inside about 162 above 90°F.
At about 56% summer humidity, the air is damp enough to blunt how well sweat cools you on the worst afternoons.
A bad day runs well past a normal one, with 114°F recorded against a 99°F summer average.

Heat in Laredo: common questions
How hot does it usually get in Laredo?
Across 2015–2024, Laredo averaged a 99°F daily high through summer, with about 162 days a year at or above 90°F and 59 at or above 100°F. July is typically the hottest month, and the hottest day in that sample reached 114°F. Figures are from ERA5 daily reanalysis.
When is the hottest time of year in Laredo?

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 Laredo right now?
The reading at the top of this page is the current wet-bulb globe temperature for Laredo, 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 Laredo?
Air temperature ignores humidity, wind, and sun: the things that decide whether heat is dangerous. Laredo's climate (one of the hottest cities in the country, this South Texas border town routinely tops 105F with brutal sun that pushes heat exposure to extreme levels.) 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 Laredo?
July is the peak month in Laredo, and within a day heat stress is highest in the early-to-mid afternoon when sun load is greatest. With roughly 59 days a year above 100°F, the safe window is often early morning rather than merely "not midday". Use the forecast on this page to find the window that works.
