KEY MESSAGES

Updated at 1225 AM PDT Sat Jun 27 2026

- Gusty onshore winds today 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 today

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

SHORT TERM

Issued at 1225 AM PDT Sat Jun 27 2026 (Tonight through Sunday)

With troughing firmly in place, below normal temperatures are expected today with coastal drizzle and pockets of light rain through the morning. As the heights tighten with the southward push of the trough, winds will be elevated again today with gusts 50+ mph through west-east passes and mountain peaks, 20-40 mph wind gusts elsewhere. 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.

Along the Pacific coastal beaches, there is a possibility for marginal coastal flooding. Due to the upcoming full moon (Monday), thermal expansion of Pacific waters, and southerly swells, coastal flooding for low lying beaches at predominantly south facing beaches is possible at high tides through Monday. 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 1225 AM PDT Sat Jun 27 2026 (Sunday night through next Friday)

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 troughing is expected to continue into next week with temperatures slowly warming into the middle of the week, but generally should remain at or below normal through the forecast period. Windy conditions will persists especially over the marine environment leading to a series of marine hazards, please see the marine discussion for further information.

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

(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 1225 AM PDT Sat Jun 27 2026

A Beach Hazards Statement has been issued for the Pacific Coast Beaches from this 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!
