Athletics: heat & lightning
WBGT heat-stress monitoring and lightning detection for schools, colleges, clubs and youth sports.
question
WBGT vs. heat index: which should athletics programs use?
Use wet-bulb globe temperature (WBGT) for outdoor practices and games. Heat index assumes shade and uses only temperature and humidity; WBGT is measured in direct sun and also accounts for wind, sun angle and cloud cover — the conditions athletes actually train in.

Lightning safety for school athletics: policy and detection options
The National Athletic Trainers' Association recommends suspending outdoor activity and moving everyone to safe shelter, then waiting 30 minutes after the last lightning strike or sound of thunder before resuming. Detection systems help you see storms coming and time that 30-minute clock reliably.
