Dangerous to record breaking heat will build across the center of the nation and slowly build eastward this week. Wildfire conditions remain critical for the Southwest and portions of the Great Basin through Monday. For the northern Plains and upper Midwest, severe thunderstorms with the potential for large to very large hail and severe winds are the primary hazards. Read More >

696 FXUS66 KMTR 290708 AFDMTR Area Forecast Discussion National Weather Service San Francisco CA 1208 AM PDT Mon Jun 29 2026 ...New SHORT TERM and LONG TERM... .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. && ..AVIATION... (06Z TAFS) Issued at 915 PM PDT Sun Jun 28 2026 Widespread VFR lasts into the night. Winds will reduce into the night, becoming light for most areas into Monday morning. Cloud cover returns to the Monterey Bay and HAF into the late night with MVFR CIGs, lower confidence in any MVFR cigs around the San Francisco Bay. This cloud cover erodes into the mid morning on Monday, leading to widespread VFR again. Vicinity of SFO...Mainly VFR through the TAF period with lower confidence in any CIGS reaching the airport near sunrise. Gusts cut off into the night and winds reduce slightly. Expect winds to become light into early Monday with breezy west winds returning that afternoon. MVFR cigs returning sometime Monday night with lower confidence on exact timing. SFO Bridge Approach...Similar to SFO. Monterey Bay Terminals...Winds reduce into the evening as come low clouds begin to flow through the area. VFR this evening transitioning into MVFR as CIGs fill over the terminals sometime around 10-11z. These CIGs look to erode into late Monday morning around 16-18z. MVFR cigs returning sometime Monday night with lower confidence on exact timing. && .MARINE... (Tonight through next Saturday) Issued at 915 PM PDT Sun Jun 28 2026 West to northwest winds continue to stay strong, resulting in hazardous seas for small craft across the waters well into the work week. Gale force gusts will continue over the northern outer waters until early Monday morning before winds reduce some, but will likely return by at times through the middle of the 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! && .MTR WATCHES/WARNINGS/ADVISORIES... CA...Beach Hazards Statement through late Tuesday night for CAZ006- 505-509-529-530. PZ...Small Craft Advisory until 3 AM PDT Tuesday for Pigeon Pt to Pt Pinos 10-60 NM-Pt Arena to Pt Reyes 0-10 nm-Pt Reyes to Pigeon Pt 0-10 nm. Small Craft Advisory until 3 AM PDT Monday for Pigeon Pt to Pt Pinos 0-10 nm. Small Craft Advisory until 9 AM PDT Monday for Pt Pinos to Pt Piedras Blancas 0-10 nm. Gale Warning until 3 AM PDT Tuesday for Pt Arena to Pt Reyes 10- 60 NM. && $$ SHORT TERM...Malarkey LONG TERM....Malarkey AVIATION...APR MARINE...APR Visit us at www.weather.gov/sanfrancisco Follow us on Facebook, X, and YouTube at: www.facebook.com/nwsbayarea x.com/nwsbayarea www.youtube.com/nwsbayarea |
