Swimming while it's raining might not seem like a big deal to a lot of people but there are some important things to consider before taking a dip in wet weather.
Indoor Swimming
Even going for a swim in an indoor pool when there's a storm outside doesn't guarantee complete shelter from nature.
LIGHTNING
Lightning and thunder aren’t always present when it’s raining but they can develop quickly and present hazards if you’re not prepared.
Electric currents from lightning can travel through metal wiring and even plumbing which means facilities like pools and locker-room showers can pose a risk during stormy weather.
Waiting 30 minutes is a good rule of thumb if you plan to swim on days like this. If you have not heard thunder within half an hour then the storm has passed enough to enter the water safely, free from lightning that may strike close by.
SLIPPERY SURFACES
Wet weather means wet surfaces. Pool surroundings can get slippery on the best of days but additional rainfall can add to the hazard and also make areas that aren’t usually wet more prone for slipping.
This is especially true for outdoor pools, however excess water can also make its way inside sheltered areas as people walk in from the weather. Be sure to warn children about the dangers of running, which can increase the risk of slipping, and to wear secure footwear.
HYPOTHERMIA
Another factor to consider on rainy days is the typical drop in temperature. This, along with stronger winds that may arise during stormy weather, can present conditions that can quicken symptoms of hypothermia if you stay cold for too long. Break up your dips in the water and make sure to dry yourself thoroughly after your swim.
It’s always best to check the weather before planning your pool visit and to consult with the lifeguard on duty during uncertain conditions before deciding to enter the water.
What about Open Water Swimming?
Swimming in open water during stormy or rainy weather can also present risks.
- The nature of currents can change unexpectedly with stronger winds, which can present challenges for less confident swimmers.
- Heavy rain has been known to hinder shoreline visibility and can create disorientation.
- Rainfall can stir up water which may instigate the flow of harmful bacteria and chemicals to accumulate towards the shoreline.
- Turbidity in water from rough weather shields visibility of hazards that can be present beneath the surface.
