Dangerous surf conditions and an elevated risk of coastal flooding will persist along much of the California coast through Wednesday, according to the National Weather Service (NWS). While current wave heights have decreased from last week’s peak, hazardous rip currents and sneaker waves remain a significant threat to beachgoers, prompting ongoing coastal flood advisories across the region.
Why are California beaches still experiencing high surf?
The current hazardous conditions are driven by a long-period south-southwest swell that continues to impact beaches across the state. According to the NWS, these swells are capable of producing powerful rip currents that can pull even experienced swimmers away from the shore. Unlike the extreme waves recorded last week, which reached up to 20 feet at iconic breaks like The Wedge in Newport Beach, current conditions are characterized by unpredictable “sneaker waves”—sudden, larger surges that can catch people on the sand off guard.
What is the status of coastal flooding?
Coastal flooding remains a concern, particularly during high tide cycles. The NWS reported that San Francisco recorded an ocean water level 1.83 feet above the predicted high tide on Saturday, marking an unusual summer high for the region. Historical data from the National Oceanic and Atmospheric Administration (NOAA) shows that such surges are typically restricted to the winter months, when seasonal storms combine with astronomical tides. Local municipalities, including the City of Newport Beach, have been actively distributing sandbags to residents in low-lying areas to mitigate damage to private property as these elevated tides continue through Tuesday.
How to stay safe in dangerous ocean conditions
Authorities emphasize that the most effective way to avoid injury is to maintain a safe distance from the water’s edge. The NWS and local lifeguards advise the following safety protocols:
- Stay off rocks and jetties: These areas are prone to being overwashed by sudden waves.
- Keep an eye on the ocean: Never turn your back on the surf while standing near the water.
- Rip current survival: If caught in a rip current, do not panic. Swim parallel to the shoreline until you are out of the current’s pull, then swim back to the beach.
- Avoid low-lying areas: Motorists should avoid parking or driving through flooded coastal roads, as wake from vehicles can push water into nearby structures.
Context: Recent incidents and regional impacts
The current weather pattern follows a period of tragic ocean-related incidents. Last week, a 5-year-old girl was recovered in Laguna Beach after being swept away by surf, and a separate incident in Santa Cruz resulted in one fatality after two women were pulled into the sea. These events have prompted officials to maintain strict warnings, reminding the public that even when waves appear smaller than historic peaks, the ocean’s energy remains life-threatening. The NWS expects conditions to begin trending toward normal by mid-week as the swell energy dissipates.
