The risk of heat related illness from vigorous sports activity increases with the temperature. The body generates heat which cannot be dissipated readily when the ambient temperature exceeds 85 degrees F, depending upon the humidity. Hot weather is considered at any point where the Heat Index reaches or exceeds 90. Coaches should follow the following procedures based on conditions:
- Heat Index up to 89°: Normal Play. Regular hydration patterns
- Heat index of 90°- 95°: Mandatory water breaks every 25 minutes.
- Heat index of 96°-102°: Mandatory water breaks every 15 minutes.
- Heat index over 103° (at start of training): All outside activity cancelled
