Texas Mandates Strict Outdoor Heat Limits for Fall High School Sports

Steps are being taken to protect students from the searing Texas heat.

Texas Schools Adopt Mandatory Wet-Bulb Heat Safety Standard for Fall Athletics

As Texas student-athletes return to practice fields this fall, high school athletic programs across the state are operating under a newly mandated safety protocol designed to prevent heat-related illnesses. According to KWTX, the newly updated rule requires all member schools to track wet-bulb globe temperatures on a consistent basis and immediately cancel outdoor practices when temperatures reach dangerous levels.

Wet Bulb, What?

Unlike traditional heat index measurements which primarily combine air temperature and relative humidity, wet-bulb globe temperature offers a broader picture by measuring direct solar radiation, wind speed, humidity, and temperature. In regions with high humidity levels, this metric provides a far more accurate representation of environmental stress on the human body.

Proactive Adjustments and UIL Findings

Many school districts proactively integrated wet-bulb monitoring into their daily athletic routines two years before the statewide mandate took effect. The UIL's policy decision was based on analysis of over 20,000 heat-illness incidents. The data revealed that every reported case occurred during practice sessions rather than games, largely due to the extended duration and intensity of daily workouts.

Schedule Changes

To adapt to the strict environmental limits, coaches are utilizing flexible scheduling:

Early Morning Practices

Evening Practices

Indoor Practices

Staying Ahead of the Heat

Athletic directors say that heat safety begins before students step outside. Hydration must be treated as an all-day commitment rather than a quick effort right before exercise.

Looking For Signs of Trouble

To prevent acute heat injuries, athletic staff and parents are advised to keep an eye out for early warning indicators, including lightheadedness, extreme thirst, heavy panting, dry mouth, or visual disturbances such as spots in peripheral sight. At the first sign of overheating, trainers must immediately apply rapid cooling techniques like ice towels or cold-water immersion.
