You don’t often hear “winterize” and “Florida” in the same sentence. Yet, for Florida pool owners, winterizing is an important process to keep your pool pristine, functioning, and damage-free. Our experts at Blue Science Pools have put together the top ways to winterize your pool to protect it during the colder months.
How Is Winterizing a Pool in Florida Different?
In most states, winterizing a pool means draining some of the water, as well as emptying the pipes. This prevents ice damage to tiles, skimmers, and the plumbing system.
In the Sunshine State, however, draining a pool isn’t recommended for a few reasons.
Potential Cracks from Groundwater

Florida is full of groundwater. While this may seem like a nonissue for a pool owner, it can become a very big problem if the water level drops in your pool. The pressure from the underground water can become so high that it will force the water upward — cracking the bottom of your empty pool in the process.
Algae Growth
A “cool” day in Florida is often still in the 50s or 60s. While you may not want to go into the water during these temperatures, something else will happily enjoy it: algae. If you neglect pool care during the colder months, you might find an unwelcome algae bloom when you do want to take a dip.
Steps to Winterize Your Pool in Florida
So how can you get your Florida pool ready for the chillier season? Follow these steps:
1. Balance Your Water Chemistry
Before winter sets in, balance the chemicals in your pool to prevent algae growth and corrosion during the colder months. Test the pH, alkalinity, and calcium hardness levels, and make any necessary adjustments so they fall within the recommended ranges. Be sure to balance the chemicals at least a week before closing the pool.
2. Clean and Vacuum Thoroughly
Remove any debris from the surface and bottom of your pool using a skimmer. Vacuum the pool to catch any remaining debris, so it doesn’t cause staining or damage. Brush the walls and tile line to remove any algae or mineral buildup, and consider applying a winterizing algaecide to prevent algae growth.
3. Cover Your Pool

Invest in a high-quality pool cover to protect your pool from falling debris, reduce evaporation, and maintain water temperature during the winter months. Make sure the cover is securely fastened to prevent it from blowing off during strong winds or storms.
4. Continue to Run Your Pump
Even while your pool is covered, you should continue to run your pump upwards of six hours a day. If a cold front is coming through, and there is a chance of frost, run it more often throughout the day and night. Circulating the water will help reduce the chance of ice damage (though this is a rare occurrence).
