UPDATED FORECAST 9-27

Southwest swell will be winding down through the day.  Another smaller run of south to southwest swell is due in Thursday through Saturday - this one should be good for shoulder to head high surf at best south facing breaks through the period.  Shorter period northwest swell and windswell will also be in the water Friday through the weekend.  Probably good for chest to head high at best north facing breaks.  Heat wave is over for now near the coast with onshore flow making a return later today with fog and coastal low clouds later.  Offshore winds will be gone too.  The rest of the week should feature northwest winds over the outer waters and far north - perhaps lighter conditions for morning sessions.  A storm system dropping down from the Gulf of Alaska will bring the first early season rain to far Northern California over the weekend, perhaps making it as far as Northern Sonoma County by Monday.  Bay Area should remain dry.  Cya in the water.
