A northwest swell churning up big waves — the first of two swells to hit the San Diego County coast this week — prompted lifeguards to close down the Ocean Beach Pier Tuesday morning.
A National Weather Service high surf advisory was in effect amid surf of 5 to 8 feet and local sets to 9 feet along the coastline south of Del Mar. The advisory is scheduled to expire at 6 p.m. today as the swell subsides.
“The large northwest swell will peak early this morning and produce high surf,” according to the weather service. “Swell and surf will gradually diminish during the day.”
However, a second swell is expected to bring similarly large and potentially damaging surf with local sets to 12 feet late Thursday into the weekend.
The elevated surf combined with strong rip currents is expected to cause dangerous swimming conditions. Forecasters said waves may break over jetties and sea walls and minor beach erosion is possible with slight coastal flooding during high tides.
Also light scattered showers, snow in areas above 5,000 feet and gusty wind are expected Thursday into Friday.
“Another large northwest swell is forecast to arrive late Thursday and continue into the weekend,” according to the weather service. “The resulting high surf will combine with strong northwest winds and high tides to threaten coastal flooding and possibly damage coastal structures.”
