Track which states require WBGT heat monitoring and what each state's lightning policy says for high school athletics. See what each rule actually demands, and get your programs ready before the next season starts.
Select a state to see its WBGT heat thresholds and lightning rules for high school athletics. States marked with a dot have a full Weatherstem compliance guide. The rest are being added as policies are confirmed.
Each summary covers what the rule requires, how WBGT must be measured, the activity thresholds, and the state's lightning policy, with links to the official sources.
State athletic rules are only half the picture. A federal OSHA heat injury and illness standard is moving through rulemaking that would cover school districts as employers, including coaches, grounds crews, and staff working outdoors. Districts that build WBGT and lightning monitoring now answer both the athletic rules and the workplace standard with one system.
Weatherstem pairs on-campus monitoring with a standards-aligned WBGT lesson for grades 9 through 12 (PE.912.C.2.9). The same data that keeps athletes safe becomes a science lesson in the classroom. No competitor offers the measurement and the curriculum together.
