If you’re wondering, “Do you have to drain pools in winter?” — especially in South Florida — the short answer is: generally, no. Draining your pool completely is rarely necessary unless you’re making major repairs, and it can even cause structural damage if not done correctly.
In our warmer South Florida climate, including Miami-Dade and surrounding areas, the need for full pool drainage during winter is minimal. Instead, the focus should be on winter pool maintenance and freezing prevention, tailored to the unique local weather conditions.
In colder regions, winters bring freezing temperatures that can damage pool plumbing and surfaces if not properly winterized. However, here in South Florida, we rarely see temperatures drop low enough to cause such issues. Therefore, draining pools in winter can present more risks than benefits.

Even though full winterization isn’t required in South Florida, maintaining your pool during cooler months is still critical to its overall health. Here’s what you should focus on:
Regularly test and balance your pool’s pH, chlorine, alkalinity, and calcium hardness. Reduced pool use during winter doesn’t mean chemistry is any less important.
Colder temperatures slow algae growth, so you can reduce your pump run time slightly — but don’t shut it off completely. A running system keeps the water circulating and helps avoid bacteria buildup.
Falling leaves and debris can still accumulate during Florida’s mild winter. Use a pool skimmer and vacuum to remove debris to prevent staining and water imbalance.
Inspect pool pumps, filters, and heaters for wear and tear. Even in mild climates, equipment can still be affected by temperature fluctuations and moisture.
In Miami-Dade and the rest of South Florida, freezing conditions are extremely rare, and when they do occur, it’s typically brief and mild. However, it’s still smart to follow preventive measures to avoid costly repairs — especially if you’re in inland or northern parts of the county that may experience occasional cold snaps.
