It is generally recommended to get out of a swimming pool when it begins to rain due to safety concerns. Here are a few reasons:
Lightning risk: Lightning is a significant hazard during a thunderstorm. Water is a good conductor of electricity, and being in a swimming pool increases the risk of being struck by lightning. Even if the pool itself is not struck, the surrounding area can still be dangerous during an electrical storm. It's safer to seek shelter indoors and away from bodies of water, including swimming pools.
Slippery surfaces: Rain can make pool decks and surrounding areas slippery, increasing the risk of slips, falls, and injuries. Wet surfaces can become quite slippery, making it difficult to maintain stable footing around the pool. Exiting the pool during rainfall helps reduce the risk of accidents due to slippery conditions.
Visibility and supervision: Rainfall can reduce visibility both in and around the pool. This can make it harder for lifeguards or other supervising individuals to effectively monitor swimmers and respond to potential emergencies. Getting out of the pool during rain ensures better visibility and facilitates proper supervision.
Water quality: Rainwater can introduce contaminants into the pool. Rain can carry pollutants from the air and surrounding surfaces, such as dirt, debris, chemicals, or bacteria. These contaminants can affect the water quality and potentially pose health risks to swimmers. It's advisable to wait until after the rain has stopped and the pool water has been properly treated or balanced before returning to swimming.
While it is generally safer to leave the pool during rain, it's important to note that local pool rules and guidelines may vary. It's always a good idea to follow any specific instructions or warnings provided by pool staff or authorities to ensure the safety of everyone involved.
