However earlier than he even activates any music, Harvey grabs his telephone and opens the Perry Climate app to examine the WBGT studying, one thing the UIL started requiring its member colleges to make the most of this yr.
As of Aug. 1, using wet-bulb globe temperature (WBGT) readings turned obligatory for all UIL athletic applications and marching bands throughout any outside observe. The UIL first began recommending colleges use WBGT readings in 2024 to find out if outside circumstances have been secure sufficient to observe in as a response to record-breaking warmth throughout the state.
Escaping the warmth
That is the primary story in a multi-part sequence on the UIL's new obligatory requirement of moist bulb globe temperature (WBGT) measurements as a part of an effort to fight warmth throughout the state.
At the moment:What moist bulb globe temperature (WBGT) is and why the UIL now requires its members to put it to use for outside practices.
Subsequent:How have coaches adjusted practices and even junior excessive schedules to abide by WBGT pointers.
Coming quickly:How just a few districts are going past simply following the rules to guard their college students from the warmth.
2024 was the identical yr San Antonio recorded its hottest yr on document, with 2023 and 2025 tying for the second hottest yr within the metropolis's historical past.
"I believe it's crucial that we take precautionary measures to actually maintain these youngsters," Harvey stated.
Not like the usual dry-bulb temperature, which is what’s often proven on climate apps and native TV, the wet-bulb globe temperature accounts for temperature, humidity, sky cowl and wind pace, in keeping with Categorical-Information meteorologist Anthony Franze.
Exterior elements outdoors of the temperature itself, like humidity, will be essential to figuring out the protection of out of doors circumstances.
"Sweat evaporates off our pores and skin and causes us to chill down," Franze stated. "Nonetheless, when there's an excessive amount of moisture within the ambiance, when it's too humid, the sweat doesn't evaporate as nicely and so our physique doesn't calm down as nicely, which causes the inner temperature to rise, forcing warmth exhaustion, warmth stroke to be extra prevalent."
The San Antonio space coaches and band administrators that spoke to the Categorical-Information in regards to the new moist bulb rule stated they agreed with the intention behind the brand new regulation.
"Participant security is of the utmost concern for all of us and so I undoubtedly perceive why the rule is in place," East Central head coach Joe Hubbard stated. "There's been so many heat-related diseases and deaths simply through the years."
Austin Bowie senior Justice Trumpler suffered a warmth stroke throughout his 2023 season opener that landed him within the ICU.

"Incidents have occurred, deaths have occurred, so we've received to ensure that as coaches we don't simply see it as a destructive and we sort of see it as a optimistic as nicely," Lanier head coach Sal Tellez stated. " We're caring for any individual else's little one once they're in our palms."
Since many faculties throughout Texas, together with these within the three largest faculty districts in San Antonio (Northside ISD, North East ISD and San Antonio ISD), have been utilizing WBGT measurements because the UIL initially made the advice in 2024, the UIL formally opted to make WBGT a requirement starting this faculty yr.
"So many have been really following the really useful coverage, and so in some bizarre approach it was punishing those that have been doing all the things we're imagined to, however there have been just a few that weren’t," UIL director of athletics Ray Zepeda stated on the annual Texas Excessive Faculty Coaches Affiliation (THSCA) conference in Houston on July 18.
The UIL has not outlined an express punishment for colleges that don’t abide by WBGT pointers, however these haven’t been a significant concern.
"Texas coaches care about their youngsters they usually observe guidelines," Zepeda stated in July.
Space coaches echoed an identical message.
"I've been within the occupation now for about 25 years and I believe most coaches would say they really feel they do a extremely good job, together with their coaching employees, of taking excellent care of children," Hubbard stated.
THSCA government director Joe Martin stated in the course of the Sept. 13 UIL Medical Advisory Committee assembly that the "overwhelming majority" of colleges are following WBGT pointers.
The UIL recommends WBGT readings to be taken quarter-hour earlier than the beginning of out of doors observe and each half-hour as soon as observe has began, and pointers regulating outside practices change into extra restrictive as WBGT readings improve. Pointers are additionally impacted by observe location. San Antonio, like most of Texas, is positioned within the space denoted as Class 3, which has the very best allowed WBGT readings for every degree of necessities.
San Antonio space colleges should adhere to those WGBT pointers:
- Out of doors practices held within the Higher San Antonio space with WBGT measurements that fall between 82.0 and 86.9 require a compulsory fast cooling zone, like a chilly water immersion tub or tarps that may be crammed with ice water to rapidly decrease any individual's inside physique temperature.
- For readings between 87.0 and 90.0, soccer gamers might put on helmets, shoulder pads and shorts in observe. If the WBGT studying reaches this threshold throughout a observe, soccer gamers can proceed carrying soccer pants while not having to alter into shorts. All outside practices at this degree will need to have 4 relaxation breaks of a minimum of 4 minutes each hour.
- Just one hour of out of doors observe is allowed when the WBGT readings vary from 90.1 to 92.0. For soccer practices, gamers might not put on protecting tools and no conditioning is allowed. Twenty minutes of relaxation have to be distributed inside the hour for all outside sports activities and marching band. Out of doors observe is prohibited when WBGT readings attain 92.1 or increased.
Davenport band director Michael Lehmann stated whereas he's seen WBGT readings on his telephone attain the extent w.right here outside observe will not be allowed, it's by no means occurred throughout a scheduled rehearsal.
"We haven't actually needed to cease a observe but and are available inside," Lehmann added.
Whereas the temperatures are beginning to drop in San Antonio as we enter the autumn season, coaches needed to discover new methods to adequately observe in the summertime warmth whereas abiding by WBGT pointers, one thing that might be explored within the subsequent a part of this sequence.
"We inform our children on a regular basis, ‘Management what you possibly can management,'" Harvey stated. "We will't management the brand new UIL coverage of no observe when the moist bulb globe temperature is X, Y, Z, A, B, C. So subsequently, we're going to seek out options."
Though the addition of a brand new rule has required varied ranges of adjustment by coaches, there stays a shared understanding of why the requirement of WBGT readings exists – to maintain college students secure.
"If we don't prefer it as a result of it's a tough rule, it's a troublesome rule, or one thing that we've by no means carried out earlier than, then we've received to seek out options that work inside the technique of it," Harvey stated. "As a result of it's in place for a motive."
