The short answer
What Determines Storm Surge Height
Storm surge is the rise in water level caused by a hurricane's winds pushing ocean water toward the shore. The height of that surge depends on the storm's intensity, its forward speed, the shape of the coastline, and the tide at landfall. A strong storm hitting at high tide can push water several feet higher than a weaker storm at low tide.
Your home's elevation above sea level is the key factor. If your house sits on a high bluff, the surge may never reach it. But if your property is close to the water or in a floodplain, even a moderate surge can flood the ground floor. Local flood maps show your elevation and flood risk zones.
- Check your home's elevation on FEMA flood maps
- Know your distance from the coast or tidal rivers
- Understand that surge can travel miles inland through waterways
- Consider that surge height adds to normal tide levels
- Look up your property's flood zone designation
How to Assess Your Home's Risk
You can find your property's elevation and flood zone through your local county or city planning office. Many online tools let you enter your address to see base flood elevation. If your home is in a high-risk zone, a storm surge may reach your level during a major hurricane.
Also consider the history of flooding in your neighborhood. Neighbors who have lived there for decades may recall past storm surges. Local building codes often require certain elevations for new construction, which tells you something about the risk in your area.
- Use FEMA's Flood Map Service Center online
- Ask your local building department about flood history and elevation data
- Talk to long-time neighbors about past flooding
- Review your insurance policy's flood coverage details
- Note any flood marks on nearby buildings or trees
What to Do Before a Storm
If a storm surge threatens your home, you need to act early. Move valuable items to upper floors or high shelves. Secure outdoor furniture and anything that could float away. Know your evacuation route and have a plan for where you will go if officials order an evacuation.
Take photos of your home and belongings before the storm hits. This documentation helps with any insurance claim later. Keep important documents in a waterproof container. If you live in Daytona Beach, keep your shutoff valve location written down so you can cut utilities quickly if needed.
- Move furniture and electronics off the floor
- Store important papers in a waterproof bag
- Charge your phone and backup batteries
- Fill your car's gas tank
- Know the nearest high-ground shelter
After the Surge Recedes
Once the water goes down, do not enter a flooded home until you are sure it is safe. Look for structural damage, such as cracks in walls or a sagging ceiling. Watch for downed power lines and standing water that may be electrified. Wear boots and gloves to protect yourself from debris and contaminants.
Floodwater often contains sewage, chemicals, and other hazards. Anything that got wet may need to be discarded, especially porous items like carpet, drywall, and insulation. Dry out the home as quickly as possible to limit mold growth. Open windows, use fans, and remove soaked materials.
- Turn off electricity at the breaker if safe
- Wear protective gear when cleaning
- Discard food that touched floodwater
- Remove wet drywall and insulation promptly
- Take photos of damage before cleanup
When to Call the Pros
Cleaning up after a storm surge is a big job. If water got into your walls, floors, or attic, you likely need professional help. The pros have industrial pumps, dehumidifiers, and moisture meters to dry your home thoroughly. They can also identify hidden damage that you might miss.
You can start by contacting a water damage inspection service to assess the extent of the damage. That assessment helps you decide what to repair or replace. The pros can handle flood cleanup, remove water-damaged flooring, and repair drywall. Policies vary, and your insurer decides what is covered.

How high can a storm surge get?
Storm surge can reach 20 feet or more in a major hurricane, but that is rare. More common surges are 3 to 10 feet. The exact height depends on the storm's strength and where it hits. Your local forecast will give specific surge predictions for your area.
Can a storm surge flood a house that is not near the beach?
Yes. Storm surge can push water miles inland through rivers, bays, and canals. Low-lying areas far from the coast can still flood. Check your flood map to see if your property is in a surge zone, regardless of your distance from the ocean.
What should I do if my home floods from storm surge?
Do not enter until it is safe. Turn off electricity if you can. Remove wet items and dry the space quickly. Call the pros for a thorough inspection and cleanup. Document everything with photos for your insurance claim. See a doctor if you feel unwell from exposure.
