KEY MESSAGES

Updated at 110 AM PDT Fri Jun 26 2026

- Gusty onshore winds today and Saturday with east-west mountain passes as high as 50+ mph and marine impacts through the weekend

- An upper trough brings cooler temperatures, moisture, and a deeper marine layer with AM drizzle this morning and Saturday

- Beach hazards return Saturday morning through Wednesday morning for south and southwest facing beaches along the Pacific Coast

SHORT TERM

Issued at 110 AM PDT Fri Jun 26 2026 (Tonight through Saturday)

Marine layer has begun to move inland for many coastal cities. It will persist through the night into the day today with most of the area partly to mostly cloudy. The marine layer is deepening closer to 2000-2500 ft, significant enough for patchy drizzle this morning along the Pacific Coast. High clouds will continue to move into the area of the the trough.

High pressure that brought above normal temperatures to the area has been replaced by a deepening trough from the Pacific Northwest. Elevated winds observed yesterday strengthen today as the gradient continues to tighten and the front moves through the area. East- west passes could see gusts up to 50+ mph with many other locations gusting up to 25-35 mph. Following the passage of the front, temperatures cooldown significantly falling 4-10 degrees compared to yesterday for most locations outside of the immediate coast. Low clouds will likely struggle to clear out this afternoon with decent moisture in the lower levels and high clouds will move in from north to south.

Additional cooling is expected for Saturday with an even deeper marine layer ushering in widespread coastal drizzle and pockets of light rain starting as early as late Friday night/ early Saturday morning. Saturday should be the coolest day of the forecast with clouds struggling to mix out in the afternoon and a slower trend to the movement of the low. While it meanders along the borders of CA/NV/OR, highs on Saturday should only reach the 50s and 60s for most spots, with low to mid 70s for interior areas, generally 10-15 degrees below normal.

The winds will increase not just for inland spots, but also for the coastal waters. More information can be found in the marine section below.

LONG TERM

Issued at 110 AM PDT Fri Jun 26 2026 (Saturday night through next Thursday)

The pattern begins to shift Sunday as the aforementioned low weakens and starts to move up into Idaho and Montana and heights slowly increase. With this, the marine layer will begin to compress a bit each day into early next week, and temperatures will slowly warm back towards normal. General model trends are pushing temperatures higher for next week, but ensemble guidance continues to favor weak troughing prevailing which would keep us a bit cooler. Should the latter prevail, the coastal waters may continue to be impacted by gusty northwest winds through much of the week, with marine hazards potentially prevailing.

The concern for hazardous beach conditions return for Pacific Coast beaches this weekend as long period southerly swells return. More information below in Beaches, but remember to never turn your back to the ocean!

AVIATION

(12Z TAFS) Issued at 419 AM PDT Fri Jun 26 2026

Generally MVFR stratus has flowed into the SF Bay Area and the Monterey Bay region, down into the Salinas Valley, while the North Bay and interior East and South Bays remain VFR. Lower confidence in a ceiling through the next couple of hours at LVK, with the note that high cloud cover is making it difficult to assess the current extent of stratus. With a deep marine layer through the day, stratus clearing will be largely delayed and limited to the interior regions, while coastal and Bayshore terminals remain socked in over the 24-hour TAF period. Gentle to moderate breezes continue through the morning hours with moderate to strong gusts resuming this afternoon and evening. Stratus will develop again in the late evening and early overnight hours, impacting most of the region with the possible exception of STS. Coastal drizzle is possible tonight into Saturday morning, extending a little beyond the end of the 24- hour TAF period.

Vicinity of SFO... MVFR stratus through the day with any scattering this afternoon being rather brief. Breezy west-northwest winds continue through the morning with gusts to 25 knots picking up again this afternoon. Not expecting gusts to reach 35 kt or above. Drizzle is possible overnight into Saturday morning, with moderate confidence on some clearing towards the end of the TAF period.

SFO Bridge Approach... Similar to SFO.

Vicinity of OAK and SJC... MVFR stratus persists through the day at OAK. At SJC, conditions remain VFR with high clouds making it difficult to determine if the stratus deck is close to the terminal, but high resolution model output shows a moderate confidence that it stays at bay through the late morning hours, before it arrives in the early afternoon and persists through the end of the TAF period. Moderate to fresh winds, west at OAK and northwest at SJC, will develop this afternoon and gradually diminish into the evening. Stratus will gradually diminish through Saturday morning close to or after the end of OAK's extended TAF period. Drizzle is possible at OAK overnight.

Monterey Bay Terminals... MVFR stratus persists at MRY through the day, with moderate to high confidence of scattering at SNS this afternoon. Moderate west winds gusting to around 20 kt will develop in the afternoon, with stratus returning to SNS in the late evening to early overnight hours. Moderate confidence in IFR stratus and drizzle at the terminals tonight through Saturday morning.

MARINE

(Today through Wednesday) Issued at 419 AM PDT Fri Jun 26 2026

Fresh to strong breezes and rough seas will persist through the weekend. These strong winds and rough seas will result in hazardous conditions for small craft across most of the coastal waters at times through at least the first half of next week. There is moderate confidence in at least occasional gales developing across coastal jet regions and the exposed coastal waters over the weekend. Long period southwest swell will persist through the extended forecast.

BEACHES

Issued at 110 AM PDT Fri Jun 26 2026

A Beach Hazards Statement has been issued for the Pacific Coast Beaches from Saturday morning through Wednesday morning as long period southerly swell returns to the coast, creating an increased risk of sneaker waves and strong rip currents, especially for south and southwest facing beaches. Hazardous beach conditions are advertised, specifically for moderate to steeply sloped beaches along the Pacific Coast of the North Bay, San Mateo, Santa Cruz counties. 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!
