Partly sunny skies across the region this morning with high clouds moving in. Isolated fog reports are coming in from southern portions of the North Bay Valleys (Novato and Petaluma) and in the vicinity of Concord. Visibilities should improve and fog coverage should diminish throughout the remainder of the morning as temperatures rise. Otherwise, expect pleasant weather with highs in the 60s across the region. The warmest portions of the Salinas Valley will reach the low 70s.

Surface high pressure across the West and a coastal trough off the Pacific Coast will continue to facilitate light offshore flow across the region. The only impact is radiational fog in the Russian River Valley. If driving in the area, slow down, use your low-beam headlights, and leave plenty of distance ahead of you. Other than that, longwave upper-level ridging across the West will result in a warming trend through Saturday with maximum temperatures around 10 degrees above normal. Higher elevation minimum temperatures will be 10 degrees above normal with coastal and valley locations near to slightly above normal. SJC will challenge its daily maximum temperature on Saturday - the previous record is 71 degrees set in 2015. Hazardous beach conditions will unfortunately coexist with fair weather, please read the BEACHES section below for more details. Minor coastal flooding is expected to return today and persist through Sunday (during the highest tides of the day) to bayshore locations along the San Francisco Bay, San Pablo Bay, and Monterey Bay. The forecast has taken into account 0.4 ft of storm surge. Confidence is moderate due to the uncertainty in: the development of the aforementioned low, the impact of the swell, and wind direction.

The aforementioned ridge will get booted out by an upper-level low in the Gulf of Alaska with the resulting pattern yielding zonal to slightly troughy flow across the region on Sunday. This will renew rain chances, but don't get too excited. The ensembles of the ECMWF and GFS show only a handful of members bringing any rain to the region during this timeframe with the official forecast keeping it all over the water. Right now, the most likely scenario looks to be a pause in the warming trend, an increase in cloud cover, and maybe some drizzle for the North Bay. Global ensemble clusters are in agreement that longwave ridging will quickly rebuild Monday, likely persisting through next Friday at least. This will yield dry weather and another warming trend with conditions very similar to what is expected in the short term.
(12z TAFS) Issued at 326 AM PST Thu Jan 29 2026
Patchy and shallow fog has developed over the Santa Rosa Plain, including at STS, and within portions of the Russian River Valley, which are expected to continue through the morning with similar conditions developing tonight. Otherwise, generally VFR conditions persist through the TAF period with a gentle onshore breeze this afternoon for the coastal terminals, while gentle offshore flow develops inland around the same time.
Vicinity of SFO, VFR through the TAF period. Light to gentle winds, generally from the east, through the morning before a gentle northwest breeze develops in the afternoon.
SFO Bridge Approach, Similar to SFO.
Monterey Bay Terminals, VFR through the TAF period. Drainage winds persist through the morning, breezy at SNS, with a light to gentle northwest wind developing in the afternoon and evening before drainage winds resume this evening.
(today through Tuesday) Issued at 920 AM PST Thu Jan 29 2026
Gentle to moderate northerly breezes continue through Friday before winds veer and become southerly over the weekend. Rough seas are expected through early Friday morning across the coastal waters, diminishing to moderate on Friday and Saturday before rough seas return Sunday and Monday.
Issued at 347 AM PST Wed Jan 28 2026
Hazardous beach conditions return to all Pacific Coast beaches tonight and persist through Friday morning. Long period westerly swell will bring an increased risk for sneaker waves and strong rip currents with breaking waves of 14 to 19 feet. Remember: stay off of jetties, piers, rocks, and other waterside infrastructure, remain out of the water to avoid hazardous surf, and never turn your back on the ocean!
