How to Open Your Pool at the Right Time?

How to Open Your Pool at the Right Time If you own a swimming pool, you might be eager to dive into the water as soon as the weather gets warmer. But before you do that, you need to open your pool properly and avoid some common mistakes.

Opening your pool at the right time can save you a lot of trouble and money. It can also help you enjoy a clean and safe pool season. Here are some tips on how to open your pool at the right time.

When to Open Your Pool

The best time to open your pool is when the outside daytime temperature is consistently above 70 degrees Fahrenheit (or 21 degrees Celsius). This is the ideal temperature for algae growth, and you don’t want algae to take over your pool water.

If you wait too long to open your pool, you might find a green and slimy mess under your winter cover. Algae can also damage your pool equipment and make your water unsafe to swim in.

To prevent algae from growing, you need to open your pool and run your filter and pump as soon as the temperature reaches 70 degrees. You also need to use the right chemicals to balance your water and kill any algae spores.

Another reason to open your pool early is to avoid the pollen season. Pollen can accumulate in your pool and make it look cloudy and dirty. It can also clog your filter and irritate your eyes and skin.

To get rid of pollen in your pool, you need to skim it regularly and use a clarifier to improve your water clarity. You can also check out this guide on how to remove pollen from your pool.

What Month to Open Your Pool

According to a survey of 1,900 pool owners, most people open their pools between May 1st and May 15th. This is a good time to get ready for the pool season, which unofficially starts on Memorial Day Weekend (end of May) in the U.S.

If you open your pool before Memorial Day, you can beat the rush and avoid the hassle of finding pool supplies and services. Pool stores are usually very busy around this time, and you might have trouble getting the chemicals and equipment you need.

You can also save some money by opening your pool early, as pool stores often offer discounts and deals before the peak season. Plus, you can enjoy your pool longer and get more value out of your investment.

What If You Have a Heated Pool

If you have a heated pool, you might think you can open it earlier or later than the 70-degree rule. However, this is not a good idea, as you still need to consider the algae factor.

Even if you heat your pool water, you can’t stop algae from growing if the outside temperature is warm enough. Algae can also grow faster in heated water, as it thrives in warm and sunny conditions.

Therefore, you should still open your pool when the outside temperature is above 70 degrees, regardless of whether you have a heated pool or not. You can always adjust your pool heater to your preferred temperature later.

How to Open Your Pool

Opening your pool is not a difficult task, but it requires some planning and preparation. You should also allow yourself at least 2-3 weeks before you plan to use your pool, as you might encounter some issues along the way.

Here are the basic steps to open your pool:

  • Remove your winter cover and store it properly.
  • Fill up your pool water to the middle of the skimmer.
  • Start your pump and filter system and check for any leaks or malfunctions.
  • Test your water and add the necessary chemicals to balance it.
  • Shock your pool to sanitize it and kill any algae or bacteria.
  • Brush and vacuum your pool to remove any dirt or debris.
  • Enjoy your pool!

If you followed these steps and opened your pool at the right time, you should have clear and sparkling water. However, if you opened your pool late or didn’t close it properly, you might have a cloudy or green pool.

Don’t worry, you can still fix it with some patience and hard work. You just need to follow these guides on how to clear a cloudy pool and how to get rid of pool algae.

How to Know If the Weather Will Stay Above 70 Degrees

The best way to know if the weather will stay above 70 degrees is to check the historical weather averages in your area. You can use online tools like Weather Underground or The Weather Channel to find out the average temperatures for each month.

Depending on where you live, you might reach the 70-degree mark sooner or later than you think. For example, in Atlanta, Georgia, the average high temperature for April is 73 degrees, while in Boston, Massachusetts, it is 56 degrees.

In the U.S., most people think about opening their pool around the middle to end of May. However, this might be too late for some areas, as the temperature could have been above 70 degrees for weeks.

If you open your pool too late, you risk having an algae outbreak and a lot of work to do. You also miss out on the opportunity to enjoy your pool before the summer crowds.

On the other hand, if you open your pool too early, you might have to deal with some cold snaps and frosty nights. In that case, you should keep your pool cover on and run your pump continuously until the weather warms up again.


Opening your pool at the right time is important for many reasons. It can help you prevent algae growth, avoid pollen accumulation, save money, and extend your pool season.

The best time to open your pool is when the outside temperature is consistently above 70 degrees. This is usually between May 1st and May 15th, but it can vary depending on your location.

To open your pool properly, you need to follow some simple steps and use the right chemicals and equipment. You should also give yourself enough time to troubleshoot any problems and clear up any water issues.

If you open your pool at the right time and take good care of it, you can enjoy a fun and relaxing pool season with your family and friends.
