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 Corpus Christi because coastal Gulf humidity keeps heat stress high day and night through a long summer. 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 Corpus Christi usually gets
Across 2015–2024, Corpus Christi averaged a 88°F daily high in summer: 61st hottest of the 174 metros we track, and August is typically the warmest month.
Heat arrives in bursts here rather than settling in, with only about 27 days a year at or above 90°F.
Humidity is the real story: summer averages about 78%, so sweat evaporates poorly and heat stress runs well above what a 88°F afternoon suggests.
It rarely strays far above its own average, topping out at 98°F in this sample.
Daily high temperatures and humidity from ERA5 reanalysis, 2015–2024 (hottest day in the sample: 2017-06-21). These are climate averages for context: the reading at the top of this page is the live one.
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 Texas heat policy page has the details, the source and the date we last checked it.
Heat in Corpus Christi: common questions
How hot does it usually get in Corpus Christi?
Across 2015–2024, Corpus Christi averaged a 88°F daily high through summer, with about 27 days a year at or above 90°F. August is typically the hottest month, and the hottest day in that sample reached 98°F. Figures are from ERA5 daily reanalysis.
When is the hottest time of year in Corpus Christi?
August has the highest average daily high in Corpus Christi. Humidity is the real story here: summer averages about 78%, 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 Corpus Christi right now?
The reading at the top of this page is the current wet-bulb globe temperature for Corpus Christi, 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 Corpus Christi?
Air temperature ignores humidity, wind, and sun: the things that decide whether heat is dangerous. Corpus Christi's climate (coastal Gulf humidity keeps heat stress high day and night through a long summer.) 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 Corpus Christi?
August is the peak month in Corpus Christi, and within a day heat stress is highest in the early-to-mid afternoon when sun load is greatest. Dangerous days are uncommon here, which is its own hazard: 27 days a year reach 90°F, and people are least acclimatized when they arrive. Use the forecast on this page to find the window that works.
