| Area Forecast Discussion National Weather Service San Francisco CA 1011pm PDT Fri September 4 2026 .SHORT TERM... Issued at 1122am PDT Fri September 4 2026 (Friday through Monday) The primary concern over the Labor Day holiday weekend is hazardous conditions at Pacific Coast beaches Friday through Monday. Two sets of long period southerly swell from distant Hurricane Karina and Hurricane Marie will result in an increased risk for sneaker waves and strong rip currents with breaking waves up to 10 feet. Remaining out of the water will not be enough, you will need to stay off of beaches, jetties, and rocks to avoid being swept into the ocean by a sneaker wave. Blue sky days are the most deadly at area beaches, don't further the narrative. Minor coastal flooding is expected during high tide for bayshore locations along the San Pablo Bay Friday afternoon/evening. Impacts can be expected primarily in bayside Marin County. Sensible weather wise, anomalously deep upper- level troughing will maintain below normal temperatures and onshore flow through Sunday. The marine layer will likely be extremely nuanced, especially today into tomorrow, as it has to form from scratch after being mixed out by the front. Generally speaking, it should be on the deeper side with the associated lift. In the interim, ample low-level moisture and clear skies will make patchy fog possible in the mornings. Gradual warming and drying trend kicks off Monday as the low begins to fill and move east. Long Term Issued at 1122am PDT Fri September 4 2026 (Tuesday through Thursday) Upper-level ridging will nose in from the east on Tuesday, likely bringing the warmest day of the week with temperatures rebounding to near normal. A reinforcing trough is expected to dig well off the West Coast and pickup what will likely be Tropical Depression Marie Tuesday into Wednesday. This will turn the upper-level pattern into a conveyor belt of moisture with cyclonic flow to the west and anti- cyclonic flow to the east. As we are dealing with two moving targets, the low and Marie, uncertainty is relatively high. It's important to note that Marie will not be making landfall in California, let alone will it be tropical by the time it gets here. We are simply going to get remnant moisture from it. The official forecast has widespread rainfall up to 0.25" with locally higher amounts up to 0.50" in the higher terrain. Right now, this looks like a beneficial event with limited instability. Marine (Tonight through next Thursday) Issued at 1010pm PDT Fri September 4 2026 West to northwest breezes will be gentle to moderate through the beginning of next week. There will be occasionally moderate to strong breezes across the San Pablo, San Francisco and Monterey Bays by the end of the weekend into the beginning of next week. Long period southerly swell has arrived with the Point Sur Buoy registering 18 second period early this afternoon out of the SSW. The long period southerly swell will continue through the weekend into the beginning of next week. Beaches Issued at 1010pm PDT Wednesday September 2 2026 A Beach Hazards Statement is in effect Friday-Monday as the swell from both Hurricane Marie and Hurricane Karina reaches the coast. As these hurricane whip up the ocean, the waves travel over 1,000 miles in all directions, gradually flattening out to low amplitude, but long period swell. These waves aren't very intimidating if you're on a boat in the open ocean, but the long period allows them to push much farther up the beach. Long period swell always increases the chance for sneaker waves, but that's particularly true this weekend since there are 2 different sets of southerly swell, and their energy will periodically combine. In addition to sneaker waves, expect strong rip currents and breaking waves up to 10 ft. As this is a holiday weekend and the weather is otherwise pretty nice, the exposure to the risk is high. Avoid the water if you're not an expert swimmer. If caught in a rip current, swim parallel to shore until you stop feeling the pull. Even on the beach, be prepared for sneaker waves this weekend and never turn your back on the ocean.
