New statewide heat safety requirements for University Interscholastic League (UIL) member schools have officially taken effect, marking one of the most significant changes to outdoor athletic and marching band safety standards in recent years.
Beginning Saturday, August 1, all UIL member schools must use Wet Bulb Globe Temperature (WBGT) measurements—not just the traditional heat index—to determine whether outdoor practices can safely continue. The new standards apply to athletics and marching band activities and are designed to better account for the combined effects of temperature, humidity, wind, and solar radiation.
What Changed Today?
The new requirements, approved earlier this year by the UIL Legislative Council, became mandatory for the 2026–27 school year on Aug. 1. According to the official UIL Rule Changes, schools must now follow required heat safety procedures instead of previous recommendations.
Under the updated rules, schools are required to:
- Measure WBGT before outdoor practices begin.
- Continue monitoring conditions every 30 minutes during activity.
- Modify practices based on heat stress levels.
- Provide rapid cooling equipment capable of full-body cold-water immersion when required.
Why WBGT Matters
Unlike the standard heat index, WBGT evaluates multiple environmental factors that affect the body’s ability to cool itself.
According to the official UIL Heat Stress & Athletic Participation Guidelines, WBGT incorporates air temperature, humidity, wind speed, and solar radiation to determine heat stress levels and establish practice restrictions.
As readings increase, schools must shorten practice times, increase hydration and rest breaks, reduce protective equipment, move activities indoors when possible, or cancel practices entirely if conditions become unsafe.
Schools Have Been Preparing
Many Texas school districts spent the summer preparing for the transition by installing WBGT monitoring systems and updating emergency procedures.
According to the Beaumont Enterprise, football teams beginning preseason workouts next week will be among the first to operate entirely under the mandatory standards. Schools that conducted spring football practices will begin later in August under the same requirements.
The UIL also requires schools to have rapid cooling equipment available to immediately treat athletes showing signs of heat illness.
Focus on Student Safety
The mandatory standards come after several years of recommending WBGT monitoring as Texas continues to experience prolonged periods of extreme summer heat.
UIL officials have said many schools already followed similar protocols voluntarily, but the August 1 implementation establishes a consistent statewide standard for all member schools.
