KEY MESSAGES

Updated at 1220 PM PDT Fri Jun 26 2026

- Gusty onshore winds through Saturday with east-west mountain passes as high as 50+ mph. Winds increase for the waters this weekend, with marine impacts through early next week

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

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

SHORT TERM

Issued at 1220 PM PDT Fri Jun 26 2026 (This evening through Saturday night)

Radar shows ongoing light rain showers across the far interior areas as a cold front moves down, associated with the larger upper level low propagating across the PacNW. With troughing firmly in place, a deeper marine layer allowed for some coastal drizzle this morning for a few spots, now currently mixing out. High clouds associated with this system continue to move into the region, helping to keep interior areas a bit cooler today. Along with these clouds, cooler 850 mb temps will usher in 10-15 degree below normal surface temperatures for both this afternoon and Saturday. As the low moves slightly southward today and tomorrow, a tighter gradient will allow for a significant uptick in onshore winds both days, with gusts 50+ mph through west-east passes and mountain peaks...20-40 mph wind gusts elsewhere. With better moisture in the lower levels, the marine layer on Saturday will remain sufficiently deep, and another round of drizzle/light rain (<0.05") is expected in the morning.

Winds will increase not only across inland areas, but also over the waters. Gusts up to 30-40 kt will be possible with seas of 8 to 10 ft. Marine hazards are currently in effect through Sunday morning, please see the marine discussion for further information.

An uptick in long period southerly swell will result in a high risk of rip currents and sneaker waves. Never turn your back to the ocean! Beach hazards will be in effect this weekend and into much of next week, see the beaches discussion for more information.

LONG TERM

Issued at 1220 PM PDT Fri Jun 26 2026 (Sunday through next Thursday)

The aforementioned low will move up to Idaho/Montana beginning Sunday, but weak troughing will remain in place over California through at least the middle of next week as high pressure attempts to push in from the west. A very slow increase in heights will support the marine layer becoming more compressed each day, but could still make it relatively far inland with patchy fog for the coastal terrain through at least Tuesday. Temperatures will follow suit, slowly warming into the middle of the week, but generally should remain at or below normal through the forecast period. Model guidance has finally started to catch on to this cooler influence from the trough, but forecasted temperatures near the end of the period may still be a bit too high depending on how long it takes for the ridge to push in.

AVIATION

(06Z TAFS) Issued at 831 PM PDT Fri Jun 26 2026

Low clouds hover over the area with MVFR/IFR conditions continuing through early Saturday morning. Pockets of BR/DZ until 12-16Z Sat, which may reduce visibilities 4-6sm within 20 miles of the coast. CIGs scattering from north to south mid morning into the early afternoon hours. Low to moderate confidence in any CIGs returning Saturday evening for the region, highest chance along the immediate coast.

Gusty westerly winds will ease slightly tonight. Winds increasing again on Saturday afternoon into the evening from north to south, where TAF sites will see gusts near 25-35 kts at times. Winds ease late Saturday night.

Vicinity of SFO...MVFR/IFR CIGs overnight, becoming MVFR in the morning. Winds will remain elevated but ease through the evening with gusts near 15-20 knots. Cloud cover lifts and scatters into the mid morning as gusty west winds return. Strong gusts build into Saturday afternoon and evening; confidence increasing with around a 60-70% chance of wind gusts reaching 35 knots 22z Sat - 05z Sun. Winds ease Saturday night.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...MVFR/IFR conditions conditions with areas of BR/DZ overnight. Winds will lessen tonight; elevated winds returning by Saturday afternoon and evening with gusts near 25 knots at times. Winds ease Saturday night.

MARINE

(Tonight through next Thursday) Issued at 831 PM PDT Fri Jun 26 2026

Winds continue to reduce through the night, increasing slightly from the Bay Area northward by the early morning on Saturday. Stronger winds become more widespread across the entire region by Saturday afternoon and night. These strong winds and rough seas will result in hazardous conditions for small craft across the waters at times well into the work week. Expect gale force gusts to develop in the northern outer waters and along coastal jet regions over the weekend as well. 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!
