Beginning Aug. 1, Texas schools participating in the University Interscholastic League (UIL) must use wet bulb globe temperature (WBGT) readings to determine whether outdoor practices and workouts can be held safely.

While the UIL first recommended WBGT monitoring in 2023, the policy is now mandatory statewide. The metric combines temperature, humidity, wind speed, and solar radiation to better estimate environmental heat stress than air temperature alone.

The new policy places schools into geographic classifications, with West Texas designated as a Class Two region. As WBGT readings increase, schools must follow progressively stricter activity modifications, including reducing practice intensity, increasing rest breaks, limiting equipment, and, when conditions become unsafe, canceling outdoor activities altogether.

Schools are also required to take WBGT readings 15 minutes before practice begins and have equipment available for full-body cold-water immersion should a student-athlete experience exertional heat illness.

Shallowater Athletic Director and football coach Rodney Vincent said his school is well prepared after adopting the recommendations two years ago.

"It's not going to be a big transition for us at all because I've got Jeremy Davis as my Athletic Trainer, he's one of the best in the state," Vincent said.

He noted that scheduling practices earlier in the day has helped reduce heat exposure, adding that protecting athletes remains the priority.

"Our number one thing here is we're gonna keep our athletes safe," Vincent said.

Vincent also encouraged coaches to rely on the expertise of Athletic Trainers and closely follow the new requirements.

"Real important that coaches follow the lead of their trainer... I just think that the UIL guidelines are going to be a good thing across the state."

FAQs

When must Texas schools take Wet Bulb Globe Temperature readings?

Under the new UIL policy, schools must record a WBGT reading at least 15 minutes before outdoor practices or workouts begin. Schools should also continue monitoring conditions if environmental factors change during activity.

How should schools adjust practice plans as WBGT rises?

The UIL's activity modification chart outlines increasing restrictions based on WBGT readings, including more frequent hydration breaks, equipment modifications, shorter practice durations, and cancellation of outdoor activity when conditions become unsafe.

Why is cold-water immersion equipment required?

Immediate whole-body cold-water immersion is considered the gold standard for treating exertional heat stroke. Having equipment readily available can significantly improve outcomes while emergency medical services are en route.

How can Athletic Trainers help schools prepare for the new UIL requirements?

Athletic Trainers can assist by reviewing Emergency Action Plans, educating coaches on WBGT thresholds, verifying heat illness protocols, and ensuring emergency equipment is available and ready before practices begin.
