Hurricanes can wreak havoc on homes, landscapes, and outdoor structures, and your swimming pool is no exception. Without proper preparation, your pool could suffer extensive damage, contamination, or even become a safety hazard. Whether you live in a coastal region prone to frequent storms or it’s just hurricane season, knowing how to prepare your pool for a hurricane is essential for protecting your investment and ensuring your home recovers quickly when the storm passes.
This guide will walk you through the key steps to protect your pool before, during, and after a hurricane, from water chemistry to equipment handling, and safety protocols.
Why Preparing Your Pool for a Hurricane Matters
Hurricanes bring heavy rains, extreme winds, and potential flooding. If your pool is not sealed or balanced properly, the storm can introduce debris, contaminants, and cause imbalances to the water chemistry. Furthermore, the risk of flooding can lead to water runoff or overflow, which can compromise both the structural integrity of your pool and the surrounding area.
Proper preparation helps prevent the following:
- Water contamination due to floodwaters and debris.
- Damage to pool equipment like pumps, filters, and heaters.
- Potentially dangerous conditions around your pool post-storm.
- Costly repairs or replacements due to preventable damage.
Step-by-Step Guide to Preparing Your Pool Before a Hurricane
The most important phase begins long before the hurricane makes landfall. Preparation timelines in hurricane-prone areas typically range from 24 to 72 hours before the predicted storm, depending on the severity and trajectory.
1. Check Your Pool’s Water Chemistry
Start by testing and adjusting the chemical balance in the pool. This includes chlorine levels, pH, alkalinity, and calcium content. During and after a hurricane, the balance can shift dramatically due to rainwater and debris. Getting your pool into optimal chemical condition before the storm helps prevent algae blooms and bacterial contamination.
Target Water Levels
- pH level: 7.4–7.6
- Chlorine: 1–3 ppm (parts per million)
- Total alkalinity: 80–120 ppm
2. Clean the Pool Thoroughly
Remove leaves, bugs, twigs, and any organic material from the water and surrounding deck area. You may also want to vacuum the pool and brush the walls. This ensures that the filtering system starts clean and can handle whatever foreign matter might find its way into the pool during the storm.
3. Maintain the Water Level
Adjust your water level as follows:
| Pool Type | Recommended Water Level |
|---|---|
| Inground Concrete Pool | Halfway up the skimmer |
| Gunite/Tile Pool | Top of the skimmer |
| above-ground pool | Within 1–2 inches of the top rail |
If you expect heavy flooding, lowering the water level slightly can help prevent overflow. However, too low may allow the pool shell to “float” due to underground water pressure.
4. Operate Your Pool Pump Until Advised Otherwise
Before the storm, running the pool pump and filter continuously (as long as electricity is available and safe) circulates the water and ensures proper chemical distribution. This helps maintain clarity and sanitation levels, especially if there’s a possibility of debris infiltrating the water.
5. Secure Pool Equipment and Accessories
Take the following precautions with pool equipment:
- Turn off electric supply to all pumps, heaters, and salt systems at the breaker box to avoid power surges.
- Remove or anchor all ladders, diving boards, and removable pool toys.
- Unplug any electrical or gas-powered pool heating units and store them indoors.
6. Use Pool Covers and Protection Methods
What to cover:
- Pool decks: Use a durable outdoor cover to prevent debris and silt from sticking to the surface.
- Pool equipment: Cover uncovered heaters, pumps, or filters with tarps.
- Pools themselves: Some people use safety covers or pool blankets to help protect the water from debris. Avoid using flimsy solar covers—it’s better to have an uncovered, maintained pool than one covered improperly.
Not all experts recommend covering the pool entirely during a hurricane, especially inground pools, due to the risk of wind lifting the cover, which can damage both the cover and the pool structure. If you choose to cover it, opt for a winter cover that’s securely fastened.
During the Hurricane: What to Do (and What Not To Do)
Once a hurricane is underway, it’s not the right time to perform preparation steps – safety must come first. Here’s what you need to know:
Do Not Enter the Pool
During the storm, do not approach or enter the pool area. Strong winds and falling debris pose a serious safety risk. Moreover, wet and windy conditions can make the surrounding surfaces slippery and hazardous.
Keep Electrical Equipment Turned Off
Even if water infiltrates the equipment area, ensure all devices remain off and the power supply is disconnected. Attempting to operate systems while flooded can cause long-term damage or electrocution.
Monitor Water Level from a Safe Location
If it’s safe and you have the opportunity to observe, watch for rising water levels caused by rain and potential overflow. However, never attempt manual adjustments during the storm.
After the Hurricane: Steps to Restore and Reopen Your Pool
The real work begins once the storm has passed and local authorities confirm it’s safe to begin clean-up.
1. Inspect Pool Structure for Damage
Start with the most important part: safety. Visually inspect your pool and deck for structural damage, including cracks, exposed rebar in inground pools, or displaced coping tiles.
Signs of Serious Concern:
- Raised sections or bulges in the pool bottom (especially in vinyl liner pools).
- Clogged or broken drains.
- Cracks around water returns or light fixtures.
If you notice significant damage, contact a licensed pool professional before proceeding with cleaning.
2. Test and Restore Water Chemistry
Even after proper preparation, hurricanes drastically affect water chemistry.
Here’s a breakdown of what to do post-storm:
- Check chlorine and pH levels, which are typically thrown out of balance by rainwater and debris.
- Skim off floating debris and vacuum the pool to remove settled contaminants.
- Shock the pool to kill bacteria and algae growth after the storm.
Once stabilized, run the filtration system continuously until the water is clear and tests consistently.
Important Note:
If floodwater contains environmental pollutants—like soil, oil, or pesticides—it may necessitate complete draining and professional cleaning.
3. Check Pool Equipment Before Reconnecting Power
Carefully inspect your pool pump, filter, salt unit, and heater before reconnecting any power. If they were submerged, consult a licensed electrician or HVAC technician before restoring them.
Do not restart equipment without proper inspection and drying—doing so could ruin the components or create a fire hazard.
4. Clean or Replace Pool Filters
Sand, cartridge, or DE (diatomaceous earth) filters should be inspected for debris and damage.
- Rinse them thoroughly if they’re in sound condition.
- If they’re clogged with fine silty material or sand, replace them to avoid damage later on.
5. Remove Excess Rainwater and Algae
You can use a pool cover pump (or a submersible pump carefully) to remove standing water on the pool’s surface.
For managing algae:
- Use algaecide in combination with heavy shock treatments.
- Brush the pool walls multiple times daily until clarity is restored.
6. Ensure Proper Drainage Around the Pool
Pooling water around equipment or deck areas can cause further issues like slip hazards or damage to underground utilities. Check your yard for improper drainage, and address any issues before using the pool again.
Optional Extra: How to Winterize or Protect a Pool When Evacuating
If you live in an area where evacuation is expected due to storm severity, the following extra precautions may be necessary to protect your pool:
1. Add Extra Chlorine and Stabilizer
Use slow-dissolving chlorine tablets or a floater and add cyanuric acid to protect chlorine from sun exposure. This prolongs sanitation, even if the pump has to be turned off.
2. Seal the Pump and Filter Area
You can use plastic or waterproof tarps to protect equipment from floodwaters. If submersion is likely, raising electrical equipment to an elevated location is ideal.
3. Leave the Pool Pump Running if Possible
If the storm is passing by rather than striking directly and power remains on, let the pump run to maintain clarity and circulation. If the outage is likely, turn it off to avoid issues with restarting.
Conclusion: Protect Your Pool the Right Way Before the Storm
Preparing your pool for a hurricane isn’t just about aesthetics or convenience—it’s about protecting your investment, ensuring safety, and enabling a quick return to normalcy after the storm passes. Proper preparation includes chemical balancing, thorough cleaning, equipment protection, and strategic adjustments to water levels.
While no two hurricanes are the same, following this comprehensive strategy offers the best chance of avoiding costly and time-consuming damage. In addition, always consult local pool professionals or disaster response agencies for area-specific advice.
By preparing efficiently, you can avoid many common post-hurricane pool issues and get your pool—and your summer—back on track quickly.
Bonus Tip: Stay informed during hurricane season. Check local forecasts, prepare early, and invest in a high-quality pool test kit and maintenance supplies before storms are in the area. These small actions can make a big difference when hurricanes strike.
What steps should I take to secure my pool area before a hurricane?
Before a hurricane hits, it’s important to secure all loose items around your pool. This includes patio furniture, pool toys, ladders, and any other objects that could become projectiles in high winds. Anchor or bring indoors any items that can’t be safely secured. Trim nearby trees and shrubs to reduce the amount of debris that could be blown into the pool or damage equipment during the storm.
Also, check the pool fencing and gates to ensure they are in good condition and can withstand strong winds. If you use a pool cover, make sure it’s properly fastened with appropriate straps or weights. These precautions not only protect your property but also help prevent debris buildup in your pool, which can complicate cleanup and damage equipment after the storm has passed.
Should I lower the water level in my pool before a hurricane?
Traditionally, people were advised to drain the pool water level below the skimmer to prevent overflow and potential damage. However, this practice is now debated among pool professionals. In modern inground pools, draining too much can cause structural issues due to groundwater pressure pushing the pool out of the ground. It’s generally safer to leave the water level at its normal height and focus instead on securing the surrounding area and equipment.
If you decide to adjust the water level, only lower it a few inches—never below the recommended levels specified in your pool’s maintenance guide. For above-ground pools, consult a professional, as draining the water may compromise the pool’s stability during high winds. When in doubt, check with a licensed pool contractor to determine the best course of action for your specific pool type and potential storm conditions.
How should I protect my pool equipment during a hurricane?
To protect your pool’s equipment, such as the pump, filter, and heater, power them off at the breaker before the storm arrives. If flooding is a concern, consider elevating or relocating sensitive components to a higher, dry location. Cover outdoor equipment with waterproof covers or plastic sheeting to help shield it from debris and water damage, but make sure the cover is secured so it won’t blow away in the wind.
Even with protective steps, it’s important to be prepared for the possibility of electrical surges or flood damage. Unplugging equipment if possible and taking it indoors offers the best protection. After the storm, do not turn the equipment back on until you’ve had it inspected for water damage or corrosion to avoid further issues or costly repairs.
Is it advisable to cover my pool before a hurricane?
Yes, using a pool cover before a hurricane is a good idea, especially if you have a solid or safety cover designed to stay on during strong weather conditions. Secure the cover properly with strong straps and anchors or water bags to prevent it from being blown off. This can minimize debris accumulation in the pool and reduce the chance of water contamination from storm runoff or falling materials.
Avoid using a standard floating cover or a solar blanket, as these can be easily torn or swept away by high winds. A properly installed safety cover—especially one that is professionally fitted—can provide the best protection for your pool during a severe storm. If you’re unsure how to install or secure your cover, reach out to a professional for guidance prior to the storm.
Will chemicals in my pool be affected by the hurricane?
Heavy rains associated with a hurricane can dilute your pool water, disrupting the chemical balance and pH levels. Additionally, debris and contaminants entering the pool during the storm can increase chlorine demand and promote algae growth. It’s wise to test your water and ensure it’s properly balanced before the hurricane—but avoid shocking the pool immediately before the storm, as runoff may wash away the chemicals.
After the hurricane passes, you’ll need to test the water again and adjust chemicals accordingly. High levels of debris may require additional sanitization and algaecide treatments. Always wait until your pool equipment has been inspected and deemed safe before running the pump or adding chemicals.
What should I do with the pool pump during a hurricane?
Before a hurricane arrives, power off the pool pump at the circuit breaker to prevent damage from electrical surges or flooding. If there’s a risk of flooding in your area, remove the pump and store it in a dry, elevated location if possible. If the pump cannot be moved, cover it securely with plastic to protect it from rain and windblown debris, but understand that submersion in floodwater can still lead to internal damage.
After the storm, ensure that all electrical systems are dry and safe before restarting the pump. If the unit was submerged or exposed to floodwater, contact a professional for inspection before attempting to use it again. Replacing a damaged pump without inspection can lead to further damage to the entire pool system and create safety hazards for the user.
How do I clean my pool after a hurricane has passed?
Once the storm has passed and it’s safe to go outside, start by visually inspecting your pool for any structural damage, such as cracks in the shell or displaced tiles. Remove large debris like branches and leaves with a net to prevent strain on your pump and filter. If your pool is extremely cloudy or discolored, test the water for chemical levels and balance accordingly.
Backwash the filter and run the pump for several hours to circulate and clarify the water. You may need to shock the pool multiple times and run the filter continuously until clarity is restored. Be cautious if the water appears black or if there’s evidence of contamination, such as gasoline or oil—contact a professional pool service if this occurs. Thorough cleaning and water testing are crucial to restoring a safe and functional swimming environment.
