Stratus continues to build into the valleys this morning, with the marine layer hovering around 1200 to 1500 ft. Upper-level ridging from the Eastern Pacific will build overhead through the period, with the warming and drier trend continuing. Temperatures today will still be slightly below to near normal with highs in the 60s along the coast, and mid 70s to mid 80s for the interior valleys. Heights continue to build into Tuesday, bringing high temps around 2 to 4 degrees warmer than today, with a pocket of Moderate HeatRisk possible around San Jose.
The marine layer, which is currently around 1200 to 1500 feet, will begin to compress through the period as ridging builds overhead. Expect stratus to retreat back to the coast by this afternoon. Slightly less stratus building inland tonight. The more compressed marine layer may allow patchy fog to develop along the coast and in wind-sheltered valleys this morning with a slightly better potential tonight/Tuesday morning.
We continue to highlight a long-period southerly swell that will bring a risk for sneaker waves and strong rip currents, with a Beach Hazards Statement out through Wednesday. If heading to the coast, 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! For more information, see the BEACHES section.

While the warming trend is still expected to peak on Wednesday, ridging has been tempered slightly, and projected high temperatures are slightly lower than previously expected. Highs will still climb into the 60s to low 70s along the coast, with upper 70s to near 90 for interior locations. A few pockets of Moderate HeatRisk are still possible, with the best potential near San Jose again. Slightly cooler but still warm temperatures for Thursday with an upper-level trough approaching the West Coast. Highs are expected to be about 1 to 3 degrees cooler from their peak on Wednesday. The cooling trend will become more noted Friday into Saturday as upper-level troughing settles the western US. The marine layer will also deepen with the troughing, and drizzle will be possible, especially along the coast. Onshore winds will increase, peaking Friday into Saturday with a frontal passage, bringing gusts 30 to 40 mph across ridgelines and through gaps and passes. A warming trend is expected to favored to begin by late weekend, but overall confidence is low as there is quite a large spread in model guidance this far out in regards to the progression of the upper trough to the east and ridging trying to creep back in from the eastern Pacific.

Erosion of marine stratus toward the coast will continue over the next few hours and nearly all terminals should be VFR in the next 1-2 hours. Main exception is KHAF where low clouds are forecast to linger through the day. Clouds moving inland again after 01Z Tue with earlier onset near the coast and later onset farther inland. Confidence in lower cigs is lowest at LVK where the threat has been covered with a TEMPO group rather than prevailing. Expect typical diurnal winds across the Bay Area and Central Coast.
Vicinity of SFO, VFR conditions will prevail into the evening hours with typical increase in winds during the late afternoon. Expect low stratus to begin moving back in after 03z with IFR conditions forecast to set in again after 06z. Similar to today, should see some improvement by mid morning with a return to VFR conditions again by midday. Moderate confidence in timing of MVFR/IFR conditions.
SFO Bridge Approach, Similar to SFO. Increased chance of BKN cigs to linger in the afternoon hours.
Vicinity of SJC and OAK, While low stratus is currently persisting at OAK, it should scatter out in the next hour or so. Expect VFR conditions to then prevail at both terminals into the early evening. MVFR conditions return after 03z Tue with IFR cigs forecast again at OAK after 06z. NW winds 5-10 knots through the period for SJC, W winds 5-15 knots for OAK.
Monterey Bay Terminals, Stratus has already cleared SNS and should clear MRY in the next hour or two as the marine layer continues to erode. VFR conditions will then prevail through the afternoon. MVFR to IFR cigs move back in after 02z and persist through the night, with restrictions persisting through late morning again Tuesday.

Gentle to moderate winds will persist through the middle of the week. Fresh to strong breezes resume over the northern waters Wednesday and Thursday, expanding southwards towards the end of the week. Seas remain moderate through Wednesday, with long period southwest swell persisting through the extended forecast.

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!
Ca, Beach Hazards Statement through Wednesday afternoon for CAZ006- 505-509-529-530.
PZ, None.
