Maybe you\u2019re wondering: when is the right time to open up my swimming pool? Well, it\u2019s better to open sooner rather than later. Otherwise, algae could start growing underneath your winter cover.<\/p>\n

So here\u2019s how to watch for the right pool-opening weather in your area.<\/p>\n

\n

When should you open your pool?<\/strong><\/h2>\n<\/div>\n

As a general rule of thumb,\u00a0you should open your pool when the outside daytime temperature stays consistently above 70 degrees (or 21 degrees celsius)<\/strong>. 70 degrees is still a little too cold to go swimming, but it\u2019s not too cold for algae.<\/p>\n

As the weather starts to warm up, algae can start to grow in your pool water \u2013 especially if you use a mesh pool cover and the water is exposed to sunlight.<\/p>\n

Springtime is also \u201cpollen season,\u201d and that can start collecting in your pool (here\u2019s a guide on getting rid of pollen in your pool<\/strong><\/u><\/a>). So to help prevent algae and stop pollen from collecting in your water, open your pool and run your filter and pump when daytime temps are a steady 70 degrees.<\/p>\n

\n

What month should you open your pool?<\/strong><\/h3>\n<\/div>\n

We surveyed 1,900 pool owners and found\u00a0a majority of pool owners open their swimming pools between May 1st and May 15th.<\/strong><\/p>\n

In the U.S. pool industry, the unofficial start of the pool season is Memorial Day Weekend (end of May). That\u2019s when pool stores are the busiest (at least in the northeast part of the country). It\u2019s a good idea to open your pool before that to get a headstart on the season and to beat the crowds in the pool stores.<\/p>\n

\n

What if you have a heated pool?<\/strong><\/h3>\n<\/div>\n

The same rule applies: you\u2019ll still want to wait for consistent 70-degree weather.<\/strong>\u00a0You just may not be able to swim in your pool if it isn\u2019t heated.<\/p>\n

Whether your pool is heated or not, plan on opening up your pool 2-3 weeks before you plan on using it. That\u2019ll give you enough time to troubleshoot equipment and clear up any water chemistry issues.<\/p>\n

If you don\u2019t have a heated pool and want to learn more about how to keep your pool heated so you can open it earlier, check out\u00a0our pool heating guide here<\/strong><\/u><\/a>.<\/p>\n

\n

What happens if you open your pool too early?<\/strong><\/h3>\n<\/div>\n

If your area experiences a surprising drop in temperatures after you\u2019ve already started up your pool again, just leave the pump running and reinstall your pool cover until the weather warms up.<\/p>\n

\n

What is the first thing you do when you open your pool?<\/strong><\/h2>\n<\/div>\n

If you closed your pool correctly and opened it earlier in the season, then hopefully you\u2019ll have clear water. The opening process is very easy.<\/p>\n

    \n
  1. Fill up the water to the middle of the skimmer.<\/li>\n
  2. Get your pump and filter system circulating again.<\/li>\n
  3. Test the water.<\/li>\n
  4. Add any chemicals needed.<\/li>\n
  5. Swim!<\/li>\n<\/ol>\n

    On the other hand, if you opened your pool and it\u2019s either green or cloudy, you\u2019ll need to check out our guides on\u00a0how to get rid of algae<\/strong><\/u><\/a>\u00a0and\u00a0how to clear a cloudy pool<\/strong><\/u><\/a>.<\/p>\n

    \n

    How do you know if the weather will stay above 70 degrees?<\/strong><\/h2>\n<\/div>\n

    Start by checking out the historical weather averages in your area. Depending on where you live, you may hit the 70-degree sweet spot sooner than you think.<\/p>\n

    In the U.S., people tend to think about opening their pool around the middle to end of May. While this feels like a good time to start swimming, it actually might be too late to open your pool.<\/p>\n

    Remember, if the temperature has stayed consistently above 70 degrees, you could be opening up your pool to an algae nightmare. And if EVERYONE opens their pool at the same time, pool chemicals and equipment might be out of stock, and pool service companies might already be booked solid.<\/p>\n
