Should I Drain My Pool Before a Hurricane?

When It Makes Sense

• Good fit: A licensed pool contractor, structural engineer, or local building official inspects your pool and recommends controlled lowering because of a known structural defect, prior damage, or unusual design condition. This is rare and should be performed under professional supervision, with a plan to refill or stabilize the shell quickly so hydrostatic pressure does not cause it to lift.
• Good fit: Local emergency-management authorities issue a specific, written order asking residents to lower pool water as part of a broader flood-control or stormwater-management plan. In that case, follow the exact instructions for how much to lower, where to discharge, and when to stop, because improper draining can create legal, environmental, and safety problems.

When You Should Avoid It

• Warning sign: You have an in-ground pool in an area with a high water table, saturated soil, or heavy expected rainfall. Removing the water inside the shell can allow groundwater to push the empty or partially empty pool upward, causing it to “pop” out of the ground, crack, separate from the deck, or damage plumbing. This risk applies to concrete, fiberglass, and vinyl-liner pools.
• Warning sign: You do not have a safe, legal discharge route, enough time to complete and monitor the draining, or expert guidance. Pumping thousands of gallons onto streets, storm drains, or saturated yards can worsen local flooding, violate municipal codes, and still leave the pool vulnerable to damage from wind and debris.

Pros and Cons

Pros

• A modest reduction in water level can sometimes reduce the amount of splash, wave action, and debris overflow onto adjacent decking if the pool has limited freeboard or poor drainage. This should be only a small adjustment, not a full drain.
• If authorities direct pool lowering as part of a community flood-control strategy, partial draining may help limit the total volume of water that must be managed by local stormwater systems.

Cons

• Draining removes the ballast that helps hold the pool shell in place. An empty or low pool is lighter and more vulnerable to hydrostatic uplift, which can shift, crack, or destroy the structure and may require expensive repair or complete replacement.
• Without water to cushion impacts, flying debris can strike the pool floor and walls directly, increasing the chance of surface damage. Draining also does not protect coping, tile, decking, equipment, or landscaping from wind and floodwater.

Decision Checklist

• What type of pool do I have, and what is the local water table? In-ground pools face uplift risk, while above-ground pools face wall collapse or frame damage if drained improperly.
• Has a qualified pool professional, structural engineer, or local emergency official specifically told me to drain the pool? General online advice is not a substitute for site-specific guidance.
• Do I have a safe, legal place to discharge the water, enough time to act, and a plan to secure equipment, remove loose objects, and manage water quality before the storm arrives?

Alternatives to Consider

In most cases, the better plan is to keep the pool filled close to its normal operating level so it retains weight and structural stability. If heavy rain is expected, you can lower the water to the middle of the skimmer opening to create room for runoff, but avoid draining more than that. Remove or secure all patio furniture, toys, cleaners, and loose equipment that could become projectiles. Turn off power to the pump, heater, and lighting at the breaker, and consider raising or protecting electrical equipment above expected flood levels. Superchlorinate the water to limit contamination from debris and storm runoff, and make sure deck drains, gutters, and overflow lines are clear. For above-ground pools, remove pumps and accessories, brace or reinforce walls according to manufacturer guidance, and never drain the shell unless directed by a professional.

Final Recommendation

For the majority of homeowners, draining a pool before a hurricane is not recommended. The safest default is to keep the water in the pool as ballast, remove hazards, protect equipment, and follow manufacturer and local emergency-management guidance. If you are considering draining because of a specific structural concern, local order, or unusual site condition, consult a licensed pool professional or structural engineer and your local emergency-management office before acting.
