Marine Weather and Tide Forecast for Lagunitas-Forest Knolls, CA

SHORT TERM
Issued at 208 PM PST Wed Jan 14 2026 (This evening through Thursday)

Sunny sky conditions have returned to the region this afternoon allowing for temperature to warm into the low to mid 60s across the North Bay, lower 60s across the East Bay, mid to upper 60s across the South Bay, and up to the low to mid 70s across the Central Coast. This is resulting a Low HeatRisk across much of the coastal and valley locations across the Central Coast. This all is thanks to high pressure aloft and north to northeast (offshore) winds in the higher elevations.

Overnight, temperatures are forecast to cool into the upper 30s to lower 40s across many of the interior valley locations.
However, cannot rule out wind sheltered spots dipping down into the low to mid 30s, especially in the North Bay valleys, southern Salinas Valley, and southern Santa Clara/Hollister valleys. There is a medium to high probability for patchy dense fog in the valleys of Sonoma County and the West Delta and adjacent inland areas (such as Concord). There is also low confidence over the San Francisco Bay south of the Bay Bridge overnight and into early Thursday morning.

Once any fog that does develop overnight and into early Thursday morning dissipates, afternoon temperatures will warm by a few degrees from today's (Wednesday) as high pressure continues to build aloft.

LONG TERM
Issued at 208 PM PST Wed Jan 14 2026 (Thursday night through next Tuesday)

The mid/upper level high pressure aloft will weaken and shift to the north just off of the Pacific Northwest coast this weekend.
This will allow for temperatures to stabilize and cool slightly over the weekend, yet will stay remain some 5 to 15 degrees above seasonal averages. Temperatures cool slight early next week (but will remain above average) with increased cloud cover across the region. However, the high pressure will remain the dominate feature aloft.

From previous forecaster: "Model confidence becomes a mess into the the last few days of next week. Agreements are fair for the ridge pattern to be broken, but the route to that result is differing across the models. The GFS models and ensembles have been calling for a cutoff low to move through the ridge and break it from the inside, which is certainly rare to see. Other longer term models show variations of a decaying ridge pattern as two stronger troughs build to the north. Either way, this does eventually call for some chances for rain to return in the last week of January. Though the path to get there and the magnitude of the rain still is a matter of debate."

AVIATION
(18Z TAFS)
Issued at 1004 AM PST Wed Jan 14 2026

Quiet and VFR conditions prevail across the CWA this morning and should continue to hold through much of the forecast period. Models are ambitious again for the overnight hours and Wednesday morning forecast, but opted to not be as aggressive as yesterday's TAF and kept visibility reductions to KSTS and KAPC based on the observations we have had so far today and the continued offshore flow.

Vicinity of SFO...Offshore winds will prevail today, with VFR conditions holding through the forecast period. Given offshore flow looks to hold, opted to avoid adding any reduced visibility since we remained in VFR overnight.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...VFR conditions and mainly offshore

MARINE
(Today through Monday)
Issued at 1004 AM PST Wed Jan 14 2026

Gentle to moderate northerly breezes will prevail today. Winds will veer to become offshore Thursday through Saturday before northerly winds return Sunday. Moderate seas will prevail through the week with the exception of the northwestern portion of the waters where rough seas will briefly build in today into tomorrow.

BEACHES
Issued at 338 AM PST Wed Jan 14 2026

Hazardous beach conditions return to all Pacific Coast beaches this morning and persist through tomorrow. Hazards include sneaker waves, strong rip currents, and large breaking waves.
Sneaker waves are potentially deadly waves that suddenly surge much farther up the beach than expected, overtaking the unaware.
They can sweep beach-goers into the ocean, roll logs and heavy debris along the beach, knocking over or pinning down unsuspecting beachgoers, and can result in cold water immersion, which can be deadly with sea surface temperatures in the 54 to 57 degrees range. Remain out of the water, stay off of waterside infrastructure such as jetties, piers, and rocks, and never turn your back on the ocean.
