Since Vancouver is unfortunately not warm year-round, there will come a time when you will need to decide what to do with your swimming pool over the winter. Will you close your pool for the season, or choose one of these methods for keeping it open? 

Either way, a decision will need to be made, but when do you need to make that decision? Let us break it down for you…


Why do you need to close your pool?

Because even though our winters are relatively mild, we still experience below-zero temperatures throughout the winter here in Vancouver. Leaving your pool open during those cold periods can cause significant damage to your pool and its equipment. 


When is the right time to close your pool?

Figuring out the ideal time to close your pool depends on a few factors, including:

Water temperature

One of the main things you need to pay attention to is your pool water’s temperature. During the summer months, it is much easier to keep your pool around 26-28°C with light use of your pool’s heater and proper use of your pool’s cover. But once overnight temperatures begin to plummet in the fall, you will either need to turn your heater up or close your pool down. Should you choose the first option, keep in mind that heating your pool can get expensive quickly, especially if you have a large pool. 

Falling leaves

Does your backyard get a lot of debris come the fall? If so, then you may want to close your pool before the trees in your neighbourhood begin to shed their leaves. Organic matter, such as leaves, can wreak havoc on your pool’s chemicals, so along with constant cleaning, you will also need to increase how often you are testing your pool’s chemicals if you keep your pool open longer. 

Be sure to clean all of the leaves out of your pool before you close it down and cover it as they can stain your pool.  

Freezing temperatures

Once outside temperatures begin to consistently drop below freezing levels, you will need to take steps in order to minimize the damage that freezing water can cause. Unless you have a proper pool heater and your pool is fully set up to be open throughout the winter, you will need to close your pool before the temperature overnight falls below -1°C. This can happen as early as September or as late as November depending on where you live in the Lower Mainland. 

Unfortunately, there is no one-size-fits-all answer for when you should close your pool, so if you are ever unsure, please contact a professional. 

Once you are ready to close things down, make sure to keep an eye out for these repairs to take care of first.
