Manhattan Beach Week in Weather: High Surf Advisory, Cooling Temperatures

MANHATTAN BEACH, CA — A look ahead to this week's weather in Manhattan Beach: temperatures lowering and a high surf advisory mid-week.

The upper ridge of high pressure that generated a heat wave starting Thursday will weaken early this week, which, together with the return of an onshore flow, will usher in a cooling trend across the Southland, forecasters said Monday.

At the same time, monsoonal flow may bring showers and thunderstorms to mountain and desert areas Monday, according to a National Weather Service statement, which added that, after a brief cooling trend midweek, conditions will warm up once again by next weekend. But for now, no heat advisories were in effect Monday morning for the first time in days.

Also expected Monday is higher surf, strong rip currents and the threat of sneaker waves that can sweep beachgoers off rocks and jetties as a result of a moderately long southerly swell that's been developing with Hurricane Eugene off the Baja California coast, according to an NWS statement. It said the surf will be even higher Tuesday morning through Wednesday evening along south- facing beaches of Ventura and Los Angeles counties, including Santa Catalina Island.

Surf of between 5 and 8 feet is expected in Los Angeles County Tuesday morning through Wednesday evening, NWS forecasters said. A high surf advisory will be in effect from 6 a.m. Tuesday to 10 p.m. Wednesday, denoting dangerous rip currents and large waves through at least Wednesday evening, a statement said. Forecasters advised beachgoers to swim near lifeguards and, if caught in a rip current, to remain parallel to shore until able to break free.

"There is an increased risk for ocean drowning, especially with more people seeking relief from the hot inland temperatures. Rip currents can pull swimmers and surfers out to sea. Large breaking waves can wash people off beaches and rocks and capsize small boats near shore," the statement said.

Under partly cloudy skies, L.A. County highs Monday will range from the high 70s near the coast to 100 in the Antelope Valley. Tuesday's temperatures will be marginally lower. Orange County temperatures will range from the mid 70s in Newport Beach and San Clemente to 90 in Yorba Linda, and also fall slightly Tuesday.
