As the temperature begins to drop, you may start to wonder about the best time to close your pool for the season. The truth is, it depends on multiple factors including your region, local weather, and how often you are using the pool. Regardless of when you actually close your pool, September is the ideal month to ensure you are prepared to keep your pool surfaces clean and protected all winter long.
Depending on what region you live in, autumn can bring a variety of different challenges for your pool. As leaves and other plant materials begin to fall, the amount of work required to keep your pool clean increases. If you find yourself skimming debris or scrubbing your pool liner daily, it may be worth it to close your pool sooner rather than later.
The temperature may be the strongest factor to consider when deciding on a time to close your pool. To keep your pool running properly it is recommended to “winterize” your pool before temperatures reach freezing, or 32 degrees. When temperatures reach this point, your pool water can freeze, which can cause damage to pool equipment.
In colder climates, pool season typically spans Memorial Day through Labor Day. For milder climates, such as Arizona or Florida, pools can stay open throughout winter. If you reside in a warmer climate, it will be up to you to decide if and when to close your pool. Consider these factors when making your decision.
- Chemical levels. It can be difficult to maintain chemical levels in the winter as your pool may not be top of mind like it is in the summer. It is more difficult for algae to grow in cooler water, but it will happen if your pH level is not balanced. Unbalanced pH and alkalinity levels can also cause stains on your pool liner or pebble pool surface.
- Even though you will likely not use your pool in the winter, you will still need to maintain your pool. The same skimming, sweeping, and pool surface cleaning schedules need to be met.
- Temperature drops. While it is unlikely for it to freeze in these regions at night, it can happen. Your pool water will not freeze if it is circulating, so ensure your pool pump is running during the coldest parts of the night, typically 2-6 a.m.
- Energy use. The amount of time you will need to run your pool pump will be 4-5 hours per night in the winter. While that is significantly less time than in the summer months, you need to decide if the energy use is worth it for a pool that is not being used.
Once you deem the water too cold for swimming, it is safe to say it is time to close your pool. Depending on your local weather and temperature tolerance, this time frame varies.
