Are indoor pools safe in a thunderstorm?
No, both indoor and outdoor pools are unsafe because a strike to any part of the complex will have a significant effect on all of it. See www.lightningsafety.com/nlsi_pls/indoor_pools.html. The NCAA and YMCA both have policies that mandate evacuation of indoor pools in the event of a thunderstorm. While there have not been any recorded deaths as a result of swimming indoors during a lightning storm, isn’t it best to play it safe?
