El Niño Overview

A powerful El Niño is building in the Pacific Ocean for late 2026 and early 2027, with NOAA's Climate Prediction Center noting a greater than 90% chance it will become "very strong" and potentially rank among the strongest events since 1950.

Expected Impacts on California

Coastal Flooding and Erosion: With sea-level rise and king tides, warmer offshore waters can raise local sea levels by up to a foot or more, threatening beaches, coastal infrastructure, and roadways.

Winter Storm Potential: While El Niño tilts the odds toward a wetter winter (especially for Southern California), it does not guarantee heavy rain or extreme storms, as seen in past mismatched events like 2015–2016.

Drought Relief: Current drought monitor levels in California are relatively low (with only about 7% in drought as of late August 2026), but a robust wet season could further secure water reserves or conversely trigger flood and landslide hazards in vulnerable areas.

Newport Beach Coastal Alert

Mother Nature isn't hitting pause. After this week's historic, record-setting tides reached an unprecedented 8.4 feet—swamping streets, garages, and homes along the Balboa Peninsula and Newport Harbor islands—city officials and forecasters urge everyone to stay alert.

What caused the intense flooding?
A massive one-two punch. The seasonal King Tides coincided with an El Niño-driven "Kelvin wave"— a powerful subsurface pulse of warm ocean water that sloshed sea levels 15 to 22 inches above standard astronomical predictions.

Looking Ahead to November:
The danger is far from over. The next round of extreme King Tides is locked in for November 24 – 26, 2026. Experts predict that additional coastally trapped Kelvin waves will continue to arrive through the winter, further elevating sea levels and worsening the risk of severe coastal flooding — especially if paired with winter storms.

How to Prepare:

• Keep sandbags ready and reinforced around low seawalls.
• Check tide apps and monitor local city advisories closely.
• Move vehicles and valuables away from flood-prone waterfront areas on high-tide mornings.
• Avoid walking or driving through flooded coastal roads.

Stay safe, stay prepared, and check in on your neighbors!
