| Area Forecast Discussion National Weather Service San Francisco CA 339pm PST Fri Nov 7 2025 .SHORT TERM... Issued at 112pm PST Fri Nov 7 2025 (This evening through Saturday) Low clouds prevail across the North Bay and down into the Bay Area with less cloud cover south of these regions. This may limit the amount of warming this afternoon, but only by a few degrees or so. However, mostly clear skies are forecast over the Bay Area and Central Coast by this afternoon as weak offshore flow aloft continues. Temperatures are forecast to warm into the low-to-mid 70s across the interior with 60s closer to the coast. For tonight, valley and wind sheltered locations will drop into the upper 40s with low-to-mid 50s elsewhere. Low clouds are forecast to return tonight and more so into Saturday morning in the North Bay, Bay Area, and into the Monterey Bay region as a shallow marine layer remains in place. Offshore flow will increase slightly in the higher terrain overnight, further drying out conditions. However, recent rainfall and generally weak north/northeast winds will limit fire weather concerns. Warmer conditions are forecast for Saturday as mid/upper level high pressure builds in from the southwest. Thus, temperatures are forecast to be 5-10 degrees above seasonal averages. Long Term Issued at 112pm PST Fri Nov 7 2025 (Saturday night through next Thursday) The warmer and drier conditions are forecast for both Sunday and Monday as the ridge shift eastward and becomes positioned over the Bay Area and Central Coast. Thus, temperatures both days with be 5- 15 degrees above normal for this time of year with mid 70s to mid 80s across the interior, with the Bay Shoreline and the Santa Cruz region reaching into the low 70s to low 80s, with mid-to-upper 60s near the coast. Again, thermal belts will remain active through early Tuesday morning resulting in mild overnight lows and breezy offshore winds in the higher terrain. From the previous forecaster: "Monday night into Tuesday will mark the start of the ridge eroding, allowing a deep upper level low to form in the east Pacific and impact the West Coast beginning Wednesday. All model guidance generally agrees that the rain should start light in the North Bay before spreading southward with increasing coverage and intensity. There is still some uncertainty regarding the exact impacts of this system, and in particular, ensemble model cluster analysis is beginning to note a significant strand of model guidance that keeps rain chances around through Saturday the 15th. However, most model and Atmospheric River guidance continues to lean towards the beneficial side of the impacts to our region." Marine (Tonight through next Wednesday) Issued at 323pm PST Fri Nov 7 2025 Rough seas will gradually diminish to moderate by Saturday with more favorable conditions expected this weekend and into the first half of next week. The next storm will bring a fresh southerly breeze and rough seas to the coastal waters by Thursday. Beaches Issued at 1048am PST Thu Nov 7 2025 Hazardous beach conditions will persist through Saturday for all coastal beaches. Expect an increased risk of sneaker waves and rip currents as well as breaking waves up to 25 feet. Remain out of the water to avoid hazardous swimming conditions, stay off of jetties, piers, and other waterside infrastructure, and never turn your back on the ocean! The increased risk for sneaker waves and rip currents will linger Friday through early Saturday morning with westerly swell quickly rebuilding.
