How to Keep a Pool Clean During Storm Season

Storm season often brings rain, wind, and debris that can quickly overwhelm your pool. From fallen leaves to contaminated water, your pool faces many challenges during this time. Fortunately, with preparation and the right routine, you can protect your pool and save yourself from stressful cleanup.

Why Storms Affect Pool Water Quality

Storms bring heavy rain, wind, and sometimes even power outages. Rainwater can dilute your pool chemicals, while wind blows in dirt, branches, and other debris. These changes can affect your pool’s pH levels, create imbalances, and even open the door for algae growth.

Pre-Storm Preparation

Taking a few steps before the storm hits can make a huge difference:

  • Skim and vacuum your pool to remove loose debris.

  • Balance your water chemistry to ensure pH, alkalinity, and sanitizer levels are within range.

  • Add algaecide as an extra layer of protection against algae blooms.

  • Secure pool equipment such as ladders, toys, and floats so they do not blow into the water.

What to Do During the Storm

While safety comes first, there are a couple of passive measures you can take:

  • Keep your pump running if possible to maintain circulation.

  • Do not cover the pool unless you have a heavy-duty cover designed to withstand storms. Lightweight covers may tear or blow away.

Post-Storm Cleanup

Once the storm passes, the real work begins:

  • Remove large debris with a skimmer net.

  • Brush walls and floors to prevent algae from forming.

  • Check and backwash the filter if needed.

  • Test water chemistry and rebalance with chlorine shock and pH adjustments.

  • Run the pump for several hours to restore water clarity.

Long-Term Pool Care During Storm Season

Storm season can last weeks or even months, so consistency is key. Stay on top of your pool’s chemistry and filtration, and schedule weekly maintenance. Keeping tools like a sturdy pool brush, reliable test kit, and clarifier on hand will help you manage sudden water issues.

A storm does not have to ruin your pool care routine. With preparation, post-storm cleaning, and consistent maintenance, you can keep your pool water safe and inviting even during storm season.
