Overcast conditions are blanketing the entire Pacific coast along Sonoma County through Monterey County this early Saturday morning. The stratus has spilled through the Golden Gate, and is also expanding through the Salinas Valley. Nearly all airports are running cooler compared to this time 24 hours ago throughout the region, including inland terminals such as Livermore and Concord. The healthy onshore gradient of +3.4 mb from SFO [San Francisco CA] to SAC [Sacramento CA] will help expand the stratus as he night progresses. ∨

Upper-level ridge remains over the eastern Pacific with northwest flow aloft prevailing over the Golden State. For this afternoon, expect seasonable temperatures along the immediate Pacific coast with temperatures in the 60s and 70s, while communities away from the oceanic influence will be much warmer in the 80s to near 100° for far inland locations. While there will be a few degrees of cooling realized today, heatrisk for the interior East Bay and South Bay will remain in the moderate category. As a result, a Heat Advisory continues for these locations through 7pm PDT this evening. ∨

High tide flooding will continue to occur nightly along the low-lying areas of the bayshore and the Pacific coast through the middle of next week. The combination of an upcoming new moon and lunar perigee on Sunday, about 7 inches of additional tidal anomaly from a combination of storm surge, thermal expansion of the eastern Pacific, and about 2 inches inches of sea level rise since the vertical datums were established in the 80s and 90s will add up to bring tides up to 2.0 feet above normal through early next week.

By Sunday and Monday, the grasp of the eastern Pacific ridge will fade as it flattens, courtesy of an Aleutian low. The end result for us will be a subtle (and welcomed) day-to-day cooling for interior communities and the usual June stratus along the Pacific coast. The ridge will attempt to rebuild around Tuesday/Wednesday, which may mark the end of the cooling trend for inland areas. ∨

Aviation. (06Z [11pm PDT] TAFs [Terminal Aerodrome Forecasts]) issued at 9:46pm PDT Friday June 12 2026 extensive stratus continues to blanket the coastal zones and adjacent valleys, locking these locations under a mix of LIFR [Low Instrument Flight Rules] ceilings. Surface visibilities have also declined with the densest pockets along the immediate coast. This marine stratus deck is projected to to hold firmly through the night before the diurnal clearing trend commences. Deep interior locations will remain decoupled from the marine influence which will maintain clear VFR [Visual Flight Rules] conditions through the TAF [Terminal Aerodrome Forecast] period. Intermediate sites, including KSTS [Santa Rosa CA], KSFO [San Francisco CA], and KOAK [Oakland CA] have moderate confidence in IFR [Instrument Flight Rules]/LIFR [Low Instrument Flight Rules] ceilings developing overnight before clearing mid-morning. ∨

Long period southerly swell will continue through the weekend, especially for south and southwest facing beaches.

A beach hazards statement is in effect for Pacific coast beaches along the Central Coast and the Bay Area coast from late tonight through late Tuesday night. Be sure check beach conditions before you head out. Sneaker waves will run up the beach much farther than other waves, potentially catching beachgoers by surprise and resulting in people being swept into the water. Rip currents are strong enough to pull the strongest swimmers away from shore. Swim near a lifeguard if possible. Stay back from the beach, and away from jetties, piers, beachside rocks, and other infrastructure near the water. Never turn your back to the ocean! ∨

Rip currents are strong enough to pull the strongest swimmers away from shore. Swim near a lifeguard if possible. Stay back from the beach, and away from jetties, piers, beachside rocks, and other infrastructure near the water. Never turn your back to the ocean! ∨ LONG PERIOD SOUTHERLY SWELL WILL CONTINUE THROUGH THE WEEKEND, ESPECIALLY FOR SOUTH AND SOUTHWEST FACING BEACHES.
