Essential Lightning Safety Tips for Swimmers

Swimming during a thunderstorm poses significant risks due to lightning. To ensure your safety, adhere to the following guidelines:

1. Recognize the Dangers of Lightning While Swimming

Lightning can strike water, causing electric currents that can be fatal to swimmers. Water is an excellent conductor of electricity, making swimming during a storm extremely hazardous.

2. Seek Shelter Immediately at the First Sign of a Storm

If you hear thunder or see lightning, exit the water and find shelter. The National Weather Service advises that when thunder roars, go indoors. (prod-01-alb-www-noaa.woc.noaa.gov)

3. Avoid Water Activities During Thunderstorms

Do not engage in swimming, boating, or other water activities when thunderstorms are forecasted. The Centers for Disease Control and Prevention (CDC) recommends postponing such activities if thunderstorms are expected. (cdc.gov)

4. Understand Safe Shelters

The safest shelter during a lightning storm is a fully enclosed building or a hard-topped vehicle with the windows rolled up. Avoid small sheds, open garages, or structures without four walls and a roof. (weather.gov)

5. Wait 30 Minutes After the Last Thunder Before Returning

After the last clap of thunder, wait at least 30 minutes before resuming swimming. This waiting period ensures that the storm has passed and reduces the risk of lightning strikes. (prod-01-alb-www-noaa.woc.noaa.gov)
