Pool Weather Safety Guide: Lightning, Wind, Heat, Chemicals, and Storm Cleanup
A pool weather safety guide for lightning, thunderstorm wind, heat, pool chemicals, flooding, debris, and when swimmers should get out.
Quick answer: If thunder is heard, swimmers should leave the pool and move to a safe building or hard-topped vehicle. Water and open pool decks are unsafe during lightning.
Lightning rule
Clear the pool at the first thunder or lightning. Do not wait for rain.
Wait at least 30 minutes after the last thunder before returning.
Wind and debris
Strong wind can blow furniture, umbrellas, branches, and pool equipment.
Secure loose items before storms arrive.
After storms
Do not swim if water is contaminated, electrical equipment is damaged, or visibility is poor.
Handle pool chemicals carefully after flooding or heavy rain.
