If you’ve recently experienced a storm, knowing how to clean a pool after a windstorm can prevent long-term damage, reduce maintenance costs, and ensure a safe swimming environment when you’re ready to use it again.
In this guide, we’ll walk you through the complete process—from initial inspection and debris removal, through filtration and chemistry balancing, to advanced maintenance tips that will keep your pool in pristine condition post-storm. Whether you have a concrete, fiberglass, or vinyl-lined pool, the steps outlined here will help you restore your pool efficiently and safely.
Step 1: Initial Inspection and Safety Precautions
Before attempting any cleaning, ensure the area and the pool are safe to approach. Here’s how to do it right:
Check for Structural Damage
Begin by visually inspecting your pool’s structure. Look for:
- Cracks in the pool shell
- Damage to coping or tile work
- Loose ladders or diving boards
- Collapsed fencing or pool covers
If you notice any major damage, do not attempt to use or clean the pool until professionals assess and repair it.
Ensure Electrical Safety
Windstorms can cause electrical disruptions, including downed power lines and flooded electrical equipment. Before cleaning:
- Turn off all pool-related electrical circuits at the breaker box
- Inspect outlets, pumps, and lights for water exposure
- Contact a licensed electrician if any equipment has been submerged or appears damaged
Step 2: Remove Large Debris from the Pool
The most immediate effect of a windstorm on your pool is the accumulation of debris—branches, leaves, dirt, and even pieces of fencing or roof materials might have blown into your pool.
Use the Right Tools
A telescopic pool pole, a leaf net skimmer, and heavy-duty gloves are essential for this step. Avoid using your bare hands to prevent injury or contamination.
Clean from the Top Down
Start by skimming the surface. Then, use a net to collect submerged debris. For heavier items like logs or furniture:
| Item Type | Recommended Removal Method |
|---|---|
| Large logs or branches | Use a skimmer or manually lift out if safe |
| Clay or dirt | Allow sediment to settle, then vacuum after filtration |
| Broken glass or sharp objects | Use caution—remove with gloves or professional help if needed |
Never leave debris in the pool overnight, as organic materials can deteriorate water quality and strain the filtration system.
Step 3: Test and Balance Water Chemistry
Windstorms often disrupt your pool’s chemical balance due to:
- Dilution from rainwater
- Contaminants introduced by debris
- Damage to sanitation systems (e.g., saltwater generators)
To restore your pool’s chemistry, you’ll need to:
Test the Water
Use a reliable test kit or bring a water sample to a pool store for analysis. Key parameters to check include:
- Free chlorine levels
- pH levels
- Total alkalinity
- Calcium hardness
- Cyanuric acid (stabilizer)
Correct Water Imbalances
Address imbalances based on the test results:
- Low chlorine? Shock the pool with a recommended oxidizing agent.
- High pH? Use pH decreaser products to normalize levels to 7.4–7.6.
- Low alkalinity? Add sodium bicarbonate to stabilize pH.
Always follow product instructions and wait at least 24 hours before re-testing to allow chemicals to circulate properly.
Step 4: Clean the Pool Interior Surfaces
Once debris is removed and your water is balanced, it’s time to clean the sides and bottom of the pool.
Brush and Vacuum the Pool
Start by brushing all pool surfaces using a brush appropriate for your pool finish—nylon brushes for vinyl and fiberglass, and stainless-steel brushes for concrete pools.
After brushing:
- Use a manual or automatic pool vacuum to remove loosened dirt.
- For fine dust or silt, switch your filter to “waste” mode during vacuuming to bypass the filter and expel water directly.
Maintaining the Filter After a Windstorm
Backwash sand and DE filters thoroughly. For cartridge filters, remove the cartridges and rinse them with a garden hose. It’s common for filters to clog after a storm, so cleaning them is essential to effective circulation.
Step 5: Circulate and Filter the Water
Proper circulation helps dilute contaminants, clear cloudiness, and evenly distribute sanitizing chemicals.
Run the Pump for Extended Hours
After cleaning, run your pool pump continuously for at least 24–48 hours. High debris levels may mean running the pump longer than usual to maintain clarity and sanitation.
Monitor and Adjust Chemical Levels
Keep a close eye on chlorine and pH levels during the first few days post-storm. Add sanitizing agents as needed and use algaecides if green spots appear.
Step 6: Inspect and Repair Pool Equipment
A windstorm may have damaged pool equipment such as:
- Pool pumps
- Filters
- Automatic cleaners
- Heaters or saltwater generators
Check for Leaks and Clogs
Inspect plumbing lines and connections for cracks or leaks. Clogged skimmer baskets or strainer lids should be cleaned to restore proper water flow.
Pump Inspection Checklist
| Component | Inspection Tips |
|---|---|
| Strainer lid | Check for cracks and replace O-ring if needed |
| Pressure gauge (for DE or sand filters) | Ensure it reflects normal operating pressure | Ensure all wiring is dry and uncorroded |
If you discover damaged equipment or notice abnormal sounds or low pressure, contact a professional pool technician for a detailed evaluation.
Step 7: Consider Professional Help for Serious Cases
Some storm-related issues are too complex to handle on your own. These include:
- Heavy flooding in the pool area
- Chemical contamination from oil or gasoline
- Significant structural damage like a cracked pool shell
- Electrical system failure that impacts the pool
In such scenarios, hire a certified pool contractor and water testing expert to ensure safety and long-term pool viability.
How to Prevent Windstorm Damage: Tips for Future Protection
To reduce the impact of future windstorms, implement preventive measures that offer long-term peace of mind.
Install a Pool Cover
A sturdy, properly anchored pool cover can prevent large debris from entering the pool during storms. Mesh safety covers are particularly effective during dry seasons.
Trim Overhanging Trees
Regularly prune branches hanging over the pool area to reduce the risk of leaves, twigs, or limbs falling during storms.
Anchor Loose Objects
Patio furniture, pool toys, and decorations can become airborne hazards. Secure them in a shed or bring them indoors before storm season.
Regular Maintenance
Staying on top of weekly chemical testing, vacuuming, and filter checks ensures your pool is always ready to withstand environmental stress.
Restoration vs. Reopening: When Is Your Pool Ready?
Determining when your pool is safe and ready for use after a windstorm involves a combination of visual, chemical, and mechanical checks.
Visual Clarity
Your water should be crystal clear, allowing visibility to the pool floor. If cloudiness persists, continue circulation and check filtration.
Chemical Readiness
Make sure:
- Free chlorine levels are 1–3 ppm
- pH is between 7.4 and 7.6
- No signs of algae or bacteria growth
Mechanical Readiness
All equipment should be functioning normally with no unusual noises or leaks. Your automatic cleaner, lights, and heater (if applicable) should operate safely.

What are the first steps I should take after a windstorm before cleaning my pool?
Before entering your pool area after a windstorm, it’s crucial to ensure your surroundings are safe. Check for downed power lines, broken glass, or structural damage near the pool. It is also important to confirm that access to the pool is free of hazards and that all storm debris is stable to prevent injury during the cleaning process.
Once safety is confirmed, turn off any electrical equipment connected to the pool system until you are certain it is safe to operate. Also, document any damage to your property, including the pool and its surroundings, for insurance purposes. This ensures you have a clear plan of action and may help in the event of a claim.
How do I remove large debris from my pool after a windstorm?
Start by skimming or manually removing large debris like branches, leaves, and other solid materials. Using a long-handled net or a leaf rake can make this easier. Avoid vacuuming large debris directly, as this can clog or damage the filtration system. Place the debris in heavy-duty trash bags for disposal.
For very heavy debris buildup, you may need to use a pool cover or tarp to gather and drag out bulk material. If the storm was particularly severe, using a wet-dry vacuum can assist with removing waterlogged debris. Always work carefully around the pool’s edges to avoid scratching the liner or surface.
Should I check the pool water chemistry after a windstorm?
Yes, a storm can introduce foreign substances like dirt, mulch, pesticide residue, and even contaminants from nearby runoff, which can disrupt your pool’s chemical balance. Use test strips or a liquid test kit to assess pH, chlorine, alkalinity, and calcium hardness levels. This is crucial for ensuring the water is safe and comfortable for swimming.
If chemical imbalances are detected, take corrective measures like adding pH increasers or decreasers, shock chlorine, or algaecide. Allow the filtration system to circulate the water after adding chemicals to ensure even distribution. Retest the water after a few hours and adjust as needed until the levels are stable.
How can I deal with cloudy or discolored pool water after a storm?
Storms can stir up sediments and contaminants that may leave your pool water cloudy or discolored. Begin by running your filter system continuously until the water clears. If the filter is overwhelmed, backwash or clean it as necessary and consider adding a clarifier to bind small particles for easier filtration.
For discolored water, especially if it appears brownish, the issue could be due to metals like iron or manganese in groundwater or runoff. In such cases, use a metal remover product and shock the pool to eliminate organic contaminants. If the problem persists, consult a professional for a detailed water analysis.
What should I do if the pool surface or equipment has sustained damage?
Windstorms can cause physical damage to the pool structure, including cracked tiles, torn liners, or broken skimmers and return jets. Inspect your pool thoroughly and note all issues. For cracked or chipped surfaces, patch kits may be used temporarily, but professional repair is recommended to prevent further damage.
Check your pump and filtration system for debris, cracks, or missing parts. If you find damage to the motor or filter tank, it’s best to replace the components before restarting the system. Always follow up with a professional if you’re unsure about the severity or repair method for any equipment damage.
How often should I backwash the filter after a storm?
Post-storm, your filter may become clogged more quickly due to excess debris and contaminants. If your pool uses a sand or DE (diatomaceous earth) filter, backwash it when the pressure gauge rises 8-10 psi above the normal starting level. For cartridge filters, remove and clean the cartridges thoroughly once they appear soiled or water flow slows significantly.
Backwashing frequency depends on how much debris entered the pool during the storm. It’s normal to backwash multiple times during cleanup. However, be cautious not to overdo it, as excessive backwashing can waste water and may not address the issue of fine particles in the water. Combine backwashing with the use of clarifiers for optimal results.
When is it safe to resume swimming after cleaning the pool post-windstorm?
Before resuming swimming, ensure that the pool water is clear, balanced, and free of any visible debris or contamination. Wait until all chemicals, especially chlorine and pH adjusters, have had sufficient time to circulate and stabilize. Typically, this can take several hours to a day after adjustments are made.
A good rule of thumb is to wait until the chemical levels are within the recommended range (pH between 7.4 and 7.6, free chlorine between 1 and 3 ppm) and the water appears sparkly and not cloudy. It’s also wise to check that all pool equipment is operating correctly and the area around the pool is free of storm-related hazards before allowing anyone to swim.
