Marine Weather and Tide Forecast for Sereno del Mar, CA

SHORT TERM
Issued at 139 AM PST Sat Nov 29 2025 (Today and tonight)

No major changes to the forecast for today outside of high temperatures in the North and East Bay. The reason being, we're expecting stratus and Tule fog to persist across the region, keeping temperatures regulated. Highs on Friday for these regions peaked in the upper 40s to low 50s, though if there was clearing, the mid to upper 50s were observed. Expect that to the be the case again today for those regions and San Francisco, with warmer temperatures elsewhere especially the Central Coast, where some upper 60s to low 70s will be possible.

Stratus and fog should return again tonight, leading to another mild night with temperatures near or just above normal for this time of year.

LONG TERM
Issued at 139 AM PST Sat Nov 29 2025 (Sunday through Friday)

More quiet weather is on tap through the extended forecast, with cluster analysis showing weak ridging to semi-zonal flow through Tue. Guidance then shows an upper level low, similar to an inside slider type situation Wed into Thu favoring breezy offshore winds for interior N Bay counties. Models then struggle for the late portion of the work week and weekend and where that low goes and if upper level high pressure can nose into the area. Right now, guidance continues to keep us dry.

AVIATION
(18Z TAFS)
Issued at 1005 AM PST Sat Nov 29 2025

A mix bag of LIFR to VFR conditions this morning depending on where you are. Conditions are forecast to gradually improve to VFR by late morning or early afternoon, the exception being across the North Bay and far interior portions of the East Bay. There is a low potential for IFR/MVFR ceilings and/or visibilities to linger through much of the day across the North Bay and East Bay. Also, passing high clouds will persist through much of the TAF period. Low ceilings and/or visibilities return late tonight and into Sunday morning before clearing by midmorning or early afternoon.

Vicinity of SFO.. MVFR (KSFO) to VFR (KOAK) currently. Conditions are forecast to improve to VFR by late morning and continue through the evening. IFR/MVFR ceilings expected to return across KSFO early Sunday morning with a later return to KOAK. Ceilings and/or visibilities improve to VFR by midmorning or early afternoon Sunday.

SFO Bridge Approach...Expecting an earlier return across the approach of IFR/MVFR ceilings Sunday morning. Otherwise, similar to SFO.

Monterey Bay Terminals...VFR. Onshore winds will increase slightly this afternoon before diminishing after sunset. There is low confidence for sub-VFR conditions early tomorrow morning.
Drainage winds likely in the Salinas Valley early Sunday morning before turning onshore by Sunday afternoon.

MARINE
(Today through Thursday)
Issued at 1005 AM PST Sat Nov 29 2025

Gentle to moderate northerly breezes will gradually develop by Sunday with strong gusts over the outer waters. Hazardous marine conditions return Sunday with building swell heights. Winds increase and wave heights build due to incoming long period westerly swell in the mid work week.

BEACHES
Issued at 139 AM PST Sat Nov 29 2025

Moderate to long period northwesterly swell will result in an increased risk for sneaker waves and rip currents. Breaking waves of 13 to 18 feet are expected. A beach hazards statement is in effect for the coastline from Sonoma County to Monterey County through 10 PM PST Sunday evening. Sneaker waves can unexpectedly run significantly farther up the beach than normal, including over rocks and jetties. Rip currents are typically more frequent and stronger in the vicinity of jetties, inlets, and piers.

Dangerous beach conditions look to continue into early next week, though there is some uncertainty as breaking wave heights flirt with High Surf Advisory criteria. Stay tuned, as and remember, never turn your back to the ocean.
