When to Close the Pool For the Winter? What You Need to Know Before Closing

After Labor Day, most pool owners have a sad realization that sets in: the time to close the pool is nearing.

The biggest question, however, is when to close the pool for the winter. You’ll want to close when the pool water is below 60 degrees. Algae is not likely to grow in cold water, so it is a good temperature to reach.

However, other factors may require closing a little earlier than water hitting that temperature. Let’s review and ensure you have a good idea of when the pool should be closed.

Do You Need to Close For Winter?

First, not all pool owners need to close their pools. Pools in warmer climates will stay open year-round.

Some pool owners will partially close, essentially keeping the pool open and running but ensuring the pool pump can run if temperatures get below freezing.

Closing the pool is a good idea if your climate is prone to prolonged freezes. This is true for those in the northern US or areas that experience four seasons.

Pool Temperature is Consistently Below 60 Degrees Fahrenheit

As stated above, the water temperature is the most important factor to know when to close the pool. Just like opening the pool, the temperature of the water should be below 60 degrees.

Algae has a much harder time growing and multiplying in colder water. Waiting until 60 degrees or below guarantees algae will not be able to spread over the winter.

This makes opening in the spring much faster and more enjoyable! Who wouldn’t want that?

Do You Need to Worry About Leaves Falling?

One factor that should be considered when closing the pool is whether many trees in the yard or neighborhood get into the pool.

While it is not always possible, you should consider covering the pool before the leaves fall. Once they start to fall, it can be real annoying scooping them out on a daily, even hourly, basis.

Consider using a leaf net to cover your pool if leaves fall earlier than expected.

Consider The Pool Company’s Schedule

If you are using a pool company to close the pool, consider their schedule more than yours.

Their calendars will start to fill up very quickly, so make sure to call and schedule as early as possible. The last thing you want to have to happen is a scheduled closing in the middle of the fall when nighttime temperatures are dropping rapidly.

Extend the Season With a Pool Heater

If you have a pool heater, you can extend your pool season into October or November if you prefer.

Consider the cost of heating the pool and how much it will be used first.

Regardless, close the pool before the nighttime temperatures fall below freezing.

Patiently Wait for Spring

We know closing the pool for winter is tough for any owner. Seeing a winter cover is much less appealing than the sparkling, clear water we all know and love.

However, pool maintenance isn’t done when you close the pool. There are things you need to consider during the winter months as well.
