| Area Forecast Discussion National Weather Service San Francisco CA 611am PDT Fri August 14 2026 .SHORT TERM... Issued at 1101pm PDT Thu August 13 2026 (Tonight through Saturday) Upper-level shortwave troughing will bring the coolest conditions of the week with well below normal temperatures and a deep marine layer Friday. The 00Z sounding observed a marine layer of 2,400 feet with satellite already showing an inland intrusion through the Delta and Pacheco Pass. With the associated lift from the aforementioned trough, drizzle can be expected along the coast and in the higher terrain via orographic lift. Smoke from the Timber Fire is expected to improve with the help of northwesterly transport winds. Long Term Issued at 1101pm PDT Thu August 13 2026 (Saturday night through next Thursday) Gradual warming trend kicks off Saturday as upper-level ridging builds into the Desert Southwest. Simultaneously, upper-level troughing will develop well off the West Coast. This will keep the ridge in check and onshore flow in place with temperatures remaining below normal. The marine layer will likely be deeper in the Bay Area than in the Central Coast with a chance for drizzle remaining across the coast and higher terrain. Global ensemble clusters are in agreement through Tuesday and then by Wednesday 60% show troughing prevailing into Thursday. Sensible weather wise, this would result in a cooling trend with increased onshore flow and the deepening of the marine layer. Marine (Today through Wednesday) Issued at 610am PDT Fri August 14 2026 Gentle to moderate northwest winds will continue through early next week. Seas will continue to subside and become moderate in response. A long period southerly swell of about 16 to 18 seconds approaches the coast Friday night into Sunday. Winds will freshen early to mid next week, causing seas to build up to 9 feet. Light drizzle is possible across the coastal waters. Haze and smoke may also impact visibility along the Big Sur coastline due to the Timber fire. NOAA San Francisco Bay Area Office: Watches - Warnings - Advisories CA...None.
