Can a hurricane actually hit San Diego?
A direct hurricane is extremely rare — the only one on record with hurricane-force winds here was in 1858 — but tropical storm remnants, heavy rain and big southerly swells are a real fall risk through November 30, and El Niño makes them more likely.
- Season ends
- November 30
- Last hurricane-force winds here

- First-ever CA tropical storm warning
- Hurricane Hilary, 2023
- 2026 swell events
- Marie (Sept 6–7) · Polo (Sept 28–29)
The short version
- The eastern Pacific hurricane season runs May 15 to November 30; September is the peak month for California impacts.
- The cold California Current normally kills storms before they arrive — but a strong El Niño warms that water and lets more moisture and swell reach us.
- In 2026, Hurricane Marie (Labor Day weekend) and Hurricane Polo (late September) sent 4–10 ft surf and coastal flood advisories to Southern California without ever coming close.
- In August 2023, Hurricane Hilary triggered the first tropical storm watch and warning ever issued for California.
- AccuWeather's May 2026 forecast called for 17–22 named storms in the eastern Pacific, with above-average risk of tropical impacts in Southern California.
San Diego sits at the same latitude as places that get hurricanes, and the eastern Pacific is one of the most active hurricane basins on Earth. The reason storms almost never arrive here as hurricanes is the ocean right off our coast: the California Current keeps local water in the 60s and low 70s, and hurricanes need roughly 80°F water to survive. They weaken fast as they move north. What does make it here is what's left of them — moisture, rain and swell.

What this fall has already shown
Two storms this September never came near California and still made local news. Hurricane Marie sent waves up to 10 feet into Southern California beaches over Labor Day weekend, flooding boardwalks in Long Beach and Venice. Then on September 28, the National Weather Service issued coastal flood and high surf advisories as swell from Hurricane Polo arrived on top of full-moon high tides near 7 feet — "nearly one foot above normal astronomical tides," in the Weather Service's words. The NWS was clear about the setup: the storms would "remain well south of Southern California, but the southerly swells from these storms will continue to affect the coastal waters."
The El Niño connection
Tropical cyclone activity in the eastern Pacific rises during El Niño, and the warmer water along Baja and Southern California lets storms hold together farther north. AccuWeather's May 2026 outlook called for 17–22 named storms and 9–13 hurricanes in the basin, and said Southern California faced "above-average risk of tropical impacts compared to historical average, as storms or tropical moisture may track farther north over exceptionally warm water."
What actually reaches San Diego — and what to do
| Southerly swell | Tropical moisture / rain | Tropical-storm winds | |
|---|---|---|---|
| How often | Most tropical seasons | Some years (Kay 2022, Hilary 2023) | Very rare |
| Risk | Rip currents, surf over seawalls, beach erosion | Flash floods, especially mountains and deserts | Downed trees and power lines |
| Your move | Swim only near an open lifeguard tower; stay off jetties | Watch NWS flash flood warnings; skip desert canyons | Secure patio furniture; charge devices |
How to keep an eye on it
- The National Hurricane Center (nhc.noaa.gov) tracks every eastern Pacific system; anything forecast to curve toward Baja is worth watching.
- NWS San Diego (weather.gov/sgx) issues the local High Surf, Coastal Flood and Flash Flood products that actually affect you.
