.SHORT TERM...
Issued at 113 PM PST Sat Nov 29 2025
(This evening through Sunday)

Tule fog continues through this weekend with solid moisture
working its way into the North Bay valleys as well. Once again had
to tamp down the temp forecast for these areas today. Persistent
fog and stratus can be expected again tomorrow with at least a
better chance for earlier clearing. Elsewhere, temperatures around
seasonal normals continue with quiet conditions and mostly clear
skies.

.LONG TERM...
Issued at 113 PM PST Sat Nov 29 2025
(Sunday night through next Friday)

Things finally start to change a bit Monday as we dry out during
the afternoons. The passage of a weak mid-level trough promotes
mixing of dry continental air, so we can finally say goodbye to
the all-day cloudiness that we`ve been seeing in the North Bay.
That`ll give everyone a few very nice days going into next week.
Next up is an inside slider that is now being advertised
with reasonable confidence by ensemble guidance. Wednesday morning
we`re anticipating offshore winds across the interior North Bay.
This will result in additional drying across the interior for
these northern zones with daytime RH in the 30-40% range, as well
as some compression of the marine layer. In terms of rain, we`re
still kicking the can down the road so to speak. Not looking good
for rain chances for anyone before the middle of the month.

.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.
