Town & Country Pool Builders, serving DC, Virginia & Maryland answer the age old question, “When should I open (or close) my pool?”

Is there a time that is ideal for opening your swimming pool? Is there a specific date on the calendar by which your pool simply must be opened? For most pool owners, and depending on the area of the country in which you live, you can’t always go by a date on the calendar; you need to rely on the weather and what your local meteorologist says. Most pool owners are anxious to get the pool opened and summer started as soon as the sun starts to shine and the swimming poolssnow has melted, but you may need to take more precautions than that.

When is the best time to open it though? You don’t want to schedule your pool contractor from Town and Country Pools to come and open the pool and then faced with unreasonable and unseasonable weather, like a freak late season snow storm. You don’t want your pool to fall prey to damage if there is a storm after it’s been opened.

If you don’t have a pool heater or solar cover, the water will not be warm enough to swim until you have several weeks of above freezing temperatures and nights that remain warm. Warm night air is as important to getting your pool water to a safe swimming temperature than warm days are. Spring days in the 70s still, in some cases, lead to nights that are barely above freezing  – not an ideal time to have your pool opened just yet.

If you have your pool opened too early your pool could become a magnet for pollen and that could lead to algae growth; that is a nightmare to clean up if it takes hold. If you’re like many pool owners, Memorial Day is the absolute latest you will want your pool opened, but for most it is a personal preference.

As for when you will close the pool; it is typically done when the nights start cooling off and the days are no longer as warm but before a freeze is predicted. If you’re running your pool heater frequently, that is also a sign for many pool owners that the time is near to close the pool. Falling leaves can also lead to both algae growth and to potential damage to your filters and pumps if they clog it up.

Again, listen to the weather forecast because both you and your pool contractor will want the pool closed before the first frost hits the area. Ask your contractor if he has a cut off date for a pool closing as he will not want to be out there working on the pool in freezing conditions. Frozen pipes can lead to broken pipes and that could be expensive to repair.

Your swimming pool contractor should be your go-to source for pool openings and closings as this is his area of expertise and he has the knowledge to know the best time for both openings and closings.
