El Niño Is Coming: Is Your North County San Diego Home Ready?

El Niño has officially returned, and this isn't shaping up to be a minor event. NOAA's Climate Prediction Center reported on August 13 that El Niño is strengthening and gives it a greater than 90% chance of becoming a very strong event during fall and winter 2026–27. NOAA even estimates a 69% chance that the October through December period could reach a strength exceeding previous El Niño events in its record dating to 1950. Importantly, NOAA also cautions that a strong El Niño increases the likelihood of certain weather impacts but does not guarantee them in any particular location.

For North County San Diego homeowners, that's an important distinction. “Very strong El Niño” does not automatically translate to “San Diego will have record-breaking rainfall.” What it does mean is that this is a reasonable year to take storm preparation seriously rather than waiting until the first major rain system appears in the forecast.

Some properties deserve extra attention. Hillside homes and properties with retaining walls should be checked for erosion, cracks, slumping or signs of soil movement. Homes with large areas of bare soil can be more susceptible to erosion and mudflow. Older homes may have aging roofs, flashing, windows or drainage systems that haven't been tested by prolonged rain in quite some time. Properties with extensive hardscape can also have runoff problems if water doesn't have a clear path away from structures.

The City of San Diego specifically recommends inspecting slopes, bare ground, drains, gutters, vegetation and roofs before storm season. Homeowners should remove debris from surface drains and gutters and make sure runoff is directed toward appropriate drainage areas rather than allowing water to saturate soil next to the home.

This is also a good year to look at your property through the eyes of water. When rain hits your roof, where does it go? Does it reach a gutter? Where does the downspout discharge? Does water flow away from the house or toward it? Are there low areas where water routinely pools? Are drains buried under leaves or landscape material? Those simple observations can reveal potential problems before a storm does.

Homeowners with older roofs should consider having them evaluated before the rainy season rather than after a leak develops. Likewise, cracked stucco, failing exterior caulking and deteriorated door seals deserve attention because wind-driven rain can find openings that ordinary light rainfall may never expose.

There is an insurance component as well. The City of San Diego reminds homeowners that most standard homeowners insurance policies do not cover flood damage; flood insurance is generally separate. If your property has a history of drainage or flooding issues—or you simply aren't sure what your policy covers—this is a good time to have that conversation with your insurance professional.

The goal isn't to worry about El Niño. It is to use the advance warning to your advantage. September and early fall give homeowners time to inspect, repair and prepare before roofing contractors, drainage specialists and other service providers become inundated with calls after the first big storm.

Next step: I have also put together a more detailed North County San Diego Rain and Storm Preparation Guide covering roofs, flashing, gutters, drainage, windows, doors and exterior surfaces. That is the checklist I would actually work through before our first significant rain.

A little preparation now can prevent a much bigger headache when the rain arrives. If you own a home in North County San Diego, this is a good time to walk your property, identify potential trouble spots, and take care of anything that has been lingering on the maintenance list.

I've also created a more detailed North County San Diego Rain and Storm Preparation Guide with specific things to check around your roof, gutters, drainage, slopes, windows and exterior. Use it as your before-the-rain checklist—and feel free to reach out if you ever need a local contractor recommendation or have a question about maintaining, improving or protecting your home's value.

Consider bookmarking this guide and doing a quick walk around your property before our first significant rain. A roof tile, clogged drain or cracked seal is much easier to address on a sunny September afternoon than during a storm.

And if you discover something you're unsure about, don't hesitate to ask. One of the benefits of working in real estate for so many years is building a network of local professionals along the way. If I have someone I trust who may be able to point you in the right direction, I'm always happy to share the resource.

Protect the home you love now—and you'll be very glad you did when the rain starts falling.
