KEY MESSAGES

Updated at 1200 PM PDT Sun Jun 28 2026

- Seasonally cool temperatures along with breezy afternoon winds persist into the middle of the week

- Gradual warming trend begins towards the end of the upcoming work week

- Increased risk of sneaker waves and strong rip currents through Wednesday morning along the Pacific coast

SHORT TERM

Issued at 1200 AM PDT Mon Jun 29 2026 (Tonight through Tuesday)

The upper level pattern over the are continues to predominately be dominated by troughing across the western United States. This will lead to seasonally cool temperatures through the work week. As the main trough system shifts to the east, a short wave trough will develop along the western periphery of the main trough following the west coast. The short wave trough will develop into a cut off low by Monday afternoon. Daytime highs today should be largely similar to those seen yesterday, with perhaps a few degrees of warming in the interior North and East Bays and a few degrees of cooling across the warmest spots of southern Monterey County.

The risk of minor coastal flooding continues through Monday night along low-lying areas in the Pacific coast and the San Francisco and San Pablo Bays. The combination of thermal expansion within the Pacific ocean, a full moon on Monday, and southerly swell will account for a little over half a foot of surge over the astronomical tide. In addition, long-period southerly swell will continue to increase the risk for sneaker waves and strong rip currents along the Pacific coast, particularly at south and southwest facing beaches. A Beach Hazards Statement remains in effect through Wednesday morning, see the BEACHES section for more details. Never turn your back to the ocean!

LONG TERM

Issued at 1200 AM PDT Mon Jun 29 2026 (Tuesday night through next Sunday)

Troughing will continue through the work week transitioning to zonal flow for the upcoming weekend, allowing a gradual warming trend to start in time for Independence Day. Towards the beginning of next week, ensemble model clusters show agreement towards a ridge building up across the Western United States, with the interaction between the ridge and any troughing over the Eastern Pacific, which would modulate how impactful the ridge ends up for our region, still to be determined.

MARINE

(Today through Saturday) Issued at 403 AM PDT Mon Jun 29 2026

Gusty northwest winds will continue mainly over the northern and outer coastal waters resulting in hazardous seas for small craft early in the week. Winds and seas will ease over the inner coastal waters from mid to late week. Long period southwest swell will persist through the extended forecast.

BEACHES

Updated at 1225 AM PDT Sun Jun 28 2026

A Beach Hazards Statement remains in effect for the Pacific Coast Beaches 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!
