Oklahoma WBGT rules for high school sports.

Oklahoma requires member schools to use one of two regional WBGT tables. Confirm your OSSAA region; PracticeCast defaults to the more conservative Region 2.

What coaches need to know

Region 2 modification bands begin at 79.7, 84.7, 87.7, and 89.8°F WBGT.
Region 3 bands begin at 82.0, 87.0, 90.1, and 92.1°F WBGT.
Higher bands add rest, cap practice at 2 hours then 1 hour, remove football equipment, prohibit conditioning, and stop outdoor activity.
OSSAA member schools must use WBGT to monitor and modify practices and workouts.
Confirm the school's assigned region before using the table.
