Weather policies, such as heat, lightning, or air quality policies, help to identify safe conditions for sport and play. Typically, these include thresholds for what is considered safe, and a pre-determined action at each threshold (e.g., “at X air quality index rating, practices and games must be moved indoors or postponed”). Having a weather policy in place can alleviate decision-making stress and allows coaches and other decision-makers to act quickly when needed.
