Wet Bulb Globe Temperature Guidance for Athletics

The California Interscholastic Federation (CIF) Extreme Heat and Air Quality Policy provides required guidance for protecting student-athletes during periods of excessive heat and poor air quality. The policy outlines how schools should use Wet Bulb Globe Temperature (WBGT) readings to assess heat risk, establishes required activity modifications and cancellation thresholds, and provides guidance for heat acclimatization and air quality monitoring during practices and competitions.

It also includes recommendations for modifying or canceling athletic activities as air quality worsens, with additional precautions for students with asthma, cardiac conditions, or other respiratory concerns.
