281800z. Coast/Valleys, Locally BKN-OVC at some beaches into the afternoon, with clear conditions elsewhere. Low clouds push inland 03-07Z Wed, with bases 700-1200 ft MSL. Most likely coastal TAF site for cigs below 1000 ft MSL is KCRQ, with only 40-50 percent chance at KSAN and KSNA. VIS 3-5SM where stratus nears higher coastal terrain and in the western valleys. Low clouds will scatter out 16- 18Z Wed.
Mountains/Deserts, Mostly clear skies and VFR conditions expected into Wednesday.
No hazardous marine weather is expected through Sunday.
A south swell from 200 degrees of 3-4 ft feet at 17 seconds will produce surf of 3-6 feet with sets to 7 feet into Wednesday. Strong rip currents are expected along with minor tidal overflow during the evening high tide.
Wednesday, a 4-5 ft swell from 160-180 degrees with a period of 13- 15 seconds associated with Hurricane Genevieve will arrive. Surf of 5-9 ft is expected on south facing beaches in Orange County with surf around 3-6 ft elsewhere. Surf will peak on Thursday and Friday, when the swell direction shifts to 180-190 degrees. Strong rip and longshore currents will create dangerous swimming conditions at most area beaches. In addition to the high surf, evening high tides will be above 6 ft this week. The combination of high tides and surf increases the risk of coastal flooding. The swell, period, and tides are expected to decrease over the weekend.
