When you know there will be bad weather is it wise to put on the pool cover an above ground or ok just leave open?

1. Protection from Debris: Strong winds and storms can carry debris such as leaves, twigs, and branches, into your pool. Putting on the cover helps prevent this debris from accumulating in your pool and potentially damaging the filter or pool liner.

2. Minimized Evaporation: Covering the pool reduces the surface area exposed to the air, minimizing water evaporation. This conserves water and reduces the need for frequent refilling, especially important in areas with water restrictions or high water costs.

3. Heat Retention: Pool covers act as insulators, helping to retain the heat in your pool water. This is particularly beneficial in cooler weather, as it allows you to extend your swimming season or reduce the need for additional heating, saving energy and costs.

4. Preventing Chemical Dissipation: Bad weather, such as heavy rain, can dilute the chemicals in your pool, making it more susceptible to algae and bacteria growth. By covering the pool, you can minimize chemical dilution, reducing the need for frequent chemical adjustments.

5. Safety Cover: Some pool covers are designed to provide a safety barrier, especially important in households with children. Leaving the pool open during bad weather poses a safety hazard as children may not be able to see the pool clearly due to heavy rain or debris.

However, it's important to ensure proper drainage to avoid water accumulating on the pool cover, which could add extra weight and put strain on the pool structure. If you're using a tarp or other non-fitted pool cover, remove any standing water after the storm to prevent damage.

Consider having a professional pool service inspect your pool and cover before extreme weather events for extra peace of mind. They can provide expert guidance on how to best protect your pool during bad weather.
