Core Event: Record-High Tides Trigger Widespread Flooding
Exceptionally high tides began inundating California’s coastline on October 26, 2026. In Huntington Beach, water rose to 2.50 m (8.20 ft), flooding the Huntington Harbor and Sunset Beach neighborhoods, closing sections of Pacific Coast Highway, and prompting a local emergency declaration by City Manager Travis Hopkins. The National Weather Service recorded a 2.60 m (8.52 ft) level at the San Diego tide gauge on October 27, 2026, the highest on record for that station. Similar surges affected Marin County, San Francisco Bay, and the San Luis Obispo, Santa Barbara, Ventura and Los Angeles counties, where coastal flood advisories remained in effect through October 30, 2026.
02
Background & Context: Seasonal King Tides and El Niño
The NWS San Diego office linked the extreme water levels to astronomically high tides occurring against an already elevated ocean surface. Thermal expansion from unusually warm Pacific waters, associated with a strengthening El Niño, added roughly 0.43 m (17 in) to sea levels compared with the previous year. The California Coastal Commission notes that El Niño conditions and oceanic Kelvin waves can temporarily raise coastal sea levels, increasing the likelihood of inundation during “king-tide” events.

On-the-Ground Reports
Residents described persistent water intrusion. One homeowner noted that “first floors are basically destroyed” after several days of several-feet-deep water. Newport Beach utility director Mark Vukojevic measured harbor water at 8 ft 3 in, only an inch lower than the previous day, and observed that “the worst has passed.”
06
Conflicting Reports & Gaps
Advisory expiration times differ across NWS offices: the coastal flood warning for Orange and San Diego counties ended at 1 p.m. PDT on Oct 29, while a lower-level advisory persisted until 2 p.m. PDT on Oct 30. The San Francisco Bay Area office extended its advisory to Nov 1, whereas the North Bay and Peninsula advisory ended on Oct 31. No publicly available data detail exact flood depths for each street, leaving a gap in precise impact assessment.

What’s Next: Anticipated Winter King-Tide Season
Forecasters project that astronomical high tides during the upcoming winter king-tide windows will exceed the October levels. Authorities continue to advise motorists to avoid flooded roadways, boaters to limit harbor traffic, and residents to secure sandbags and monitor city updates as the threat persists into late November and December.
