Updated at 1215 AM PDT Mon Jun 22 2026 - Hazardous beach conditions along the Pacific Coast through Wednesday - Minor HeatRisk with below to near normal temperatures Monday - Warming trend with pockets of moderate HeatRisk possible across the Santa Clara Valley and East Bay Interior Valleys Tuesday through Thursday, peaking Wednesday && .SHORT TERM... Issued at 303 PM PDT Mon Jun 22 2026 (This evening through Tuesday) Status continues to erode for all, but the immediate coast and through the Golden Gate. The west-northwest feed of stratus looks to keep all but the Golden Gate stratus persistent through the afternoon. Areas that started the day cloud-free are building into the 70s and 80s, with temperatures there expected in the mid 80s to low 90s. For the inland areas that started the day off with cloud cover but cleared: temperatures will range from the 70s to 80s this afternoon. Coastal areas that remain in the stratus look to stick to the upper 50s and low 60s. Cloud cover will build back inland slightly later this evening, but will not reach as far inland due to the the marine layer compressing into the night. Temperatures will remain cool overnight with most areas staying in the mid 50s. The reduction of marine influence from the compressed marine layer will call for the inland areas to continue the warming trend on Wednesday while the coast and near-coast areas remain cool. Inland areas will build into the 80s while the far interior areas look to peak in the mid to upper 90s. && .LONG TERM... Issued at 303 PM PDT Mon Jun 22 2026 (Tuesday night through next Sunday) Wednesday looks to offer nearly identical temperatures to Tuesday, with a few areas in the more inland portions of the region trending a few degrees warmer. The pattern begins to change on Thursday after another warm afternoon, leading into a breezy evening with better onshore flow. A trough deepens into the area at the end of the week, leading to a resurgence of the marine layer and breezy to gusty winds. The increased on shore flow will kick off a cooling trend on Friday, with Saturday seeing the coolest high temperatures of the forecast with mostly 60s and 70s. && .AVIATION...

Updated at 1215 AM PDT Mon Jun 22 2026 Long period southerly swell at around 14 to 16 seconds will increase to 17 to 19 seconds by the middle of the week as energetic storms in the Southern Hemisphere continue to affect the California coast, 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. A Beach Hazards Statement for Pacific Coast beaches continues through Wednesday afternoon. Be sure to check beach conditions before you head out. 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...
