What OSAA’s document says
OSAA runs on heat index, not WBGT: “Schools shall monitor the heat index for their geographic area prior to practices”, and at a heat index of 105°F or above OSAA calls for all outside activity to stop. OSAA names its own tool: “By OSAA policy, schools are required to check their practice location’s heat index through the OSAA Heat Index Calculator, no other site.” So treat the reading here as planning information, and get the heat index for your practice location from OSAA’s calculator.
We won’t show another state’s WBGT thresholds in its place: regional tables differ by several degrees. Follow the policy your school, district or league has adopted. For general heat guidance at your field, open the map.
OSAA Heat Index PolicyThis is a plain-language summary to help you plan. It is not legal advice, and it is not the association’s document. Associations revise these policies often. Confirm what currently applies with your school, district or association.
What else to know
- Indoor activities with air conditioning are exempt from OSAA’s policy. At its highest heat-index level, OSAA calls for activity to stop indoors as well as outside wherever air conditioning is unavailable.
- OSAA sorts the heat index into five levels: Safe below 80°F, then Notice, Caution and Warning, and Danger at 105°F or above.
How to read this
We found no WBGT limits in OSAA’s document. It uses the heat index instead, so there is no WBGT table to show. Your school or district may also have its own heat policy.
Before you rely on this
- This page summarizes OSAA’s document. It does not replace it. If they differ, go by the document and by the policy your school or league has adopted.
- Confirm what currently applies with your school, district or association. Many schools adopt their own version.
- Any WBGT number WetBulbTracker shows is a modeled estimate for planning, not an official reading. Where a policy calls for an on-site reading, that reading governs.
- This page does not replace an athletic trainer’s judgment.
