.SHORT TERM...
Issued at 103 AM PST Sun Nov 30 2025
(Today and tonight)
High clouds make life for the meteorologist a little difficult this
morning, as it blocks the low level clouds that are being
observed in the North Bay, East Bay, and San Francisco region. The
question for today, is, you guessed it, much like yesterday and
pertains to if or when will the clouds clear out around there.
Guidance favors perhaps a few hours earlier today, perhaps the
early afternoon hours instead of the mid to late. Given that,
opted to go with slightly higher temperature forecast than
yesterday's observed temperatures for the N Bay and surrounding
areas. Highs will still be below normal there by about 0 to 10
degrees, while the rest of the region is closer to normal for this
time of year.

.LONG TERM...
Issued at 103 AM PST Sun Nov 30 2025
(Monday through Saturday)
The forecast remains on track for the extended period, with the
first feature being stratus clearing out for the North and East Bays
Monday and Tuesday afternoon. An inside slider remains on tap for
midweek, which will bring breezy conditions to the interior North
Bay hills Wednesday morning. Conditions will dry out as well in
terms of minRH values; however, no major fire weather concerns are
expected. Beyond that, the slider looks to dig south, which should
allow for upper level ridging to build towards us. Dry weather
remains in the forecast with near seasonal to slightly warmer than
normal high temperatures expected for the end of the week.

.AVIATION...
(18Z TAFS)
Issued at 954 AM PST Sun Nov 30 2025
Varying conditions from LIFR to VFR this morning depending on
where you are. Low ceiling and visibilities will gradually improve
to VFR by midmorning or early afternoon, earlier than yesterday.
Weak to occasionally moderate offshore winds persist in the higher
terrain across the region and is mixing down to the terminals at
times this morning. Onshore winds are expected to return this
afternoon for a brief period, then become light and variable late
tonight and offshore early tomorrow morning across the Bay Area.
Low clouds are forecast to return to the Bay Area terminals
(potential for fog in and around KSTS) early Monday morning with
an earlier clearing time than today. Lower confidence for the
Monterey Bay terminals for low ceilings and/or visibilities. Any
low clouds and/or fog that does develop are expected to clear
earlier on Monday as offshore flow may persist throughout much of
the day, especially across the Bay Area terminals.
Vicinity of SFO...IFR to MVFR conditions persist at KSFO, yet
conditions are forecast to return to VFR later this morning, just
before or around noon. Onshore winds are also expected by this
afternoon before becoming variable overnight. Offshore winds are
then forecast to return early Monday morning with the potential
for IFR/MVFR conditions. As offshore flow prevails early Monday
morning and into the afternoon, we are expecting an earlier
clearing time compared to today.
SFO Bridge Approach...Similar to SFO.
Monterey Bay Terminals...VFR at KMRY and LIFR at KSNS, yet
expecting to improve to VFR here in the next few hours. Onshore
winds are forecast to increase slightly this afternoon and then
ease overnight. Low probability for IFR to sub-IFR conditions
early Monday morning, likely around sunrise and shortly there
after.

.MARINE...
(Today through Friday)
Issued at 954 AM PST Sun Nov 30 2025
High pressure will remain located off of the Oregon coast
maintaining northerly breezes through the week. Northerly flow
will increase throughout the day today and gradually diminish into
Monday. Winds will be locally stronger over the outer waters and
coastal jets. Wave heights and swell energy increase early this
week.
&&
.BEACHES...
Issued at 828 PM PST Sat Nov 29 2025
Hazardous beach conditions will continue into next week with a
very energetic surf zone.
A beach hazards statement remains 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.
A set of forerunner waves arrive early next week renewing the
danger for sneaker waves.
