State heat policies and WBGT guidelines

Where Sports Safe doesn't have a state chart, it uses the Korey Stringer Institute's regional WBGT guidelines and labels them that way in the app. You can also choose a different chart for any field in its settings.
These pages summarize each policy for convenience. Sports Safe is not affiliated with or endorsed by any state association. Always confirm the current rules with your association and follow your school's emergency action plan. Sports Safe estimates WBGT from weather data; it is not a WBGT meter.
