Marine Weather and Tide Forecast for Roseland, CA

SHORT TERM
Issued at 124 PM PDT Tue Apr 14 2026 (This evening through Wednesday)

Low level stratus is breaking up across the Bay Area with sunny skies to continue into the afternoon/evening. Another round of stratus is expected tonight along the coast and portions of the SF Bay Shoreline. Locally patchy fog remains possible tonight across the interior valleys, particularly across the North Bay Valleys and southern Salinas Valley. The upper level pattern remains fairly stable in the short term as a deep upper level trough moves into the PNW and more meridional flow (becoming slightly troughy on Wednesday) prevails over California. This will result in Tuesday looking fairly similar to Monday with coastal highs in the 50s to 60s, interior highs in the 60s, and portions of the interior Central Coast in the low 70s. Morning low temperatures will be in the 40s to low 50s with portions of the interior Central Coast and the elevated terrain dropping into the upper 30s. Diurnally breezy onshore winds continue through Wednesday with gusts to around 20 to 30 mph across favored gaps/passes and along the coast in the afternoon/evening. There is some potential for coastal drizzle on Wednesday but if any does occur no accumulation is expected.

LONG TERM
Issued at 124 PM PDT Tue Apr 14 2026 (Wednesday night through next Monday)

There is a slight pattern change Wednesday night into Thursday as a high amplitude ridge moves into the West Coast. This will bring gusty offshore (northerly) winds across the region with gusts between 30-40 mph across the highest peaks. Winds will be strongest across the North Bay Interior Mountains and the interior East Bay.
Fire concerns remain minimal thanks to the recent wetting rains across the region last weekend. Winds shift onshore again by Saturday and continue through the remainder of the Long Term Forecast. High temperatures will see a gradual warming trend Thursday into the weekend with highs building back into the mid to upper 70s across the interior and 60s along the coastline. By Sunday, the upper level ridge will have progressed eastward and another deep upper level trough will move into the West Coast. This low is coming from the Gulf of Alaska and will bring us our next round of rain. The highest rain totals look to be in the coastal mountain ranges with lower amounts expected across the rest of the Bay Area and Central Coast. Temperatures will cool Sunday and Monday with interior highs in the 60s to low 70s on Sunday dropping into the low to mid 60s on Monday. Coastal high temperatures will remain in the 50s to 60s. Gusty onshore winds are possible Sunday into Monday as this next system arrives but it does not meet Wind Advisory Criteria.

AVIATION
(00Z TAFS)
Issued at 429 PM PDT Tue Apr 14 2026

Strong onshore winds will gradually taper off over the next 3-6 hours this evening. High clouds associated with a cold front over far northern California will start to spill over the Bay Area and Central Coast tonight. Under these pre-frontal clouds, there will still be some marine layer stratus impacts before the actual surface front moves through Wednesday night.

Vicinity of SFO...Sustained winds have remain between 15-20 knots for the last few hours. These strong winds will persist for another couple hours before the sea breeze impacts decrease later this evening. There is a 20-30% chance for MVFR ceilings through 18Z Wednesday before the low clouds should start mixing out. More than likely the ceilings will be transient and temporary through the first 18 hours of the TAF.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...With a better exposure to the ocean, the southern terminals have the best chance for MVFR ceilings early Wednesday morning. Despite this, there is very little chance for them to drop below 1,000 feet.

MARINE
(Tonight through next Sunday)
Issued at 429 PM PDT Tue Apr 14 2026

High pressure over the NE Pacific will continue to support a fresh NW breeze and moderate seas over the coastal waters through Wednesday afternoon. A mostly dry cold front will push through Wednesday night, followed by a push of strong to near gale force NW'rlys Thursday. These winds will build rough seas of 10-12 feet across the exposed coastal waters. Winds will ease back to a moderate NW breeze Fri-Sat, allowing seas to gradually subside.
