You Have to Do Winterize a Pool in Southern California? 2024

If you live in Southern California, you might think that you do not need to winterize your pool during the winter. After all, you enjoy some of the mildest weather in the country. However, when the daily temperatures get a bit cooler than normal, you might find yourself using the pool less, and this would be a great time for some pool winterization.

Sudden changes in temperature and harsh weather conditions still occur in Southern California in the winter and can cause problems in your pool. A professional pool maintenance team can help you take the necessary steps to winterize your Southern California pool to prevent these problems. Our team of experienced professionals at Aqua Masters Inc. can help you understand if and how you can protect your pool when the season changes.

What Does it Mean to Winterize Your Pool?

Often confused with closing your pool, winterizing your pool means that you are not going to use it for several months. Since most pool owners do not use their pool in the winter season, the term is called “winterizing.”

Winterizing your pool involves cleaning and inspecting the pool and taking protective measures that keep it structurally sound when it is out of use. For instance, if you choose to winterize your pool, you will need to: 

  • Clean in and Around the Pool: If you are going to stop using your pool for a season, you want to make sure it is clean when you close it down. This means that you will have to clean the walls, floor, steps, and areas around the pool.
  • Use Winterizing Chemicals: If you want to prevent the growth of organisms like algae during the winter months, you should use chemicals that balance your pool. To understand what chemicals you should use for your specific pool, you should consult a professional pool maintenance team.
  • Lower Your Water Level: Keeping water in your pool during the winter is important to keep it working properly. However, you should lower the level of water to avoid issues with scaling, corrosion, and staining.
  • Cover Your Pool: If you want to avoid debris and volatile temperature fluctuations during the winter, you should consider adding a cover that protects your pool.

How Much Does Winterizing Your Pool in Southern California Cost?

The amount that you will have to pay to winterize your pool in Southern California will depend on a lot of factors unique to your property. For example, the amount and type of chemicals you need to balance your pool and the products you need for effective cleaning will depend on the size and upkeep of your pool.

When you consult with a pool service provider, they can review the contextual factors surrounding your pool to determine a precise estimate of how much winterizing will cost you. It is important to keep in mind that while winterizing might be an investment, you might end up having to pay more to fix environmental damages to your pool if you choose not to winterize.


Q: Should I Cover My Pool in Winter in California?

A: Whether or not you cover your pool in California is ultimately up to you. However, covering your pool can save you a great deal of time, energy, and money spent on maintenance tasks. When you leave your pool open in winter, even in a warm climate, you might encounter more debris in the water and heat loss. You might have to spend more money and energy on heating the pool in cooler temperatures.

Q: How Long Should I Run My Pool Pump in the Winter in California?

A: The hours you should run your pool pump in the winter in California will depend on specific contextual factors. For example, depending on the size of your pool and your local weather conditions, you might need to run it more or less than other pool owners. In general, many Southern Californians reduce the operation of their pool pump to about four to six hours a day. A pool maintenance professional can examine your pool and give you an informed recommendation.

Q: What Will Happen to my Pool if I Don’t Cover it in the Winter?

A: If you do not cover your pool in the winter, you might find that your maintenance tasks and costs go up. For example, more frequent storms can result in more debris that you have to clean from your pool. You might also find that you need to heat your pool more frequently and that you need more chemical treatments. The precise impacts will depend on your environment and your pool.

Q: Is It Better to Leave Water in My Pool Over Winter?

A: It is usually in your interest to leave water in your pool during the winter months to preserve your pool’s structure. Without water in your pool, you could end up with structural damage in your pool, and it might cave in. Sometimes, you might need to reduce the amount of water in your pool, but leaving some is usually preferable to none.

Q: How Do You Winterize a Pool in Southern California?

A: Winterizing your pool yourself can be tricky and time-consuming, so it is in your interest to contact a pool maintenance professional to do it for you. If you choose to winterize it alone, you will have to clean the area around the pool and the walls and floors, inspect all of the equipment, balance all of the chemicals, flush the filtration systems and clean up the filters, and finally cover the entire pool with a pool cover.
