What IHSAA’s document says
IHSAA does not set outdoor activity by any measured instrument. Its safety model asks that “all practices shall allow for water breaks and general acclimatization to hot and/or humid weather” and prints no heat thresholds; the only numeric heat chart it publishes anywhere is a National Weather Service heat-index graph. So there is no Idaho WBGT ladder for us to show you.
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.
IHSAA Fall Sports Practice/Safety Model: Heat Stress and Athletic ParticipationThis 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
- IHSAA’s fall practice model limits sessions whatever the weather: in football, cross country and soccer, “Each practice session will be a maximum of 2.5 hours in length”, with no more than four hours of on-field practice a day.
- IHSAA recommends “a minimum 10-minute water break” for “every twenty minutes of heavy exercise in the heat”, and says water “must be on the field and readily available to the athletes at all times”.
- IHSAA’s sports medicine page links NATA’s “Beat the Heat” infographic, which advises measuring with WBGT and sets no limits. That is NATA’s advice, not an IHSAA rule.
- Idaho, Indiana and Iowa each have an association called IHSAA, and of the three only Iowa’s publishes a WBGT policy, so check the state on any IHSAA document you are handed.
How to read this
We found no WBGT limits in IHSAA’s document, and no other measured heat limit, so there is no table to show. Your school or district may still have its own heat policy, so ask.
Before you rely on this
- This page summarizes IHSAA’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.
