.SHORT TERM...
Issued at 147 PM PDT Sun Oct 11 2026
(This evening through Monday night)
Quiet weather is being observed across the Bay Area and Central
Coast, with a few cumulus clouds popping up over some mountains and
stratocu over our southern marine forecast areas. Water vapor
imagery shows dryer air entrenched over the northern half of the
state, thanks to an upper level trough. Models, including the NBM,
still hint at light showers for far southern Monterey and San Benito
counties late tonight and into Monday morning though the dry air
might keep it as virga or mid and high clouds instead. Outside of
those precip chances, dry weather prevails for Sunday and Monday and
it will be accompanied with cool temperatures.

.LONG TERM...
Issued at 147 PM PDT Sun Oct 11 2026
(Tuesday through next Saturday)
The upper level trough does barrel towards NV and UT late Monday
into early Tuesday morning leading to some lighter offshore flow.
High pressure over the eastern Pacific will be building and working
its way into the region, leading to temperatures slightly warming.
The ridge continues to build into the region on Wednesday which will
kick off the more notable warming trend for the rest of the week.
The aforementioned upper level trough looks to center itself over
WY/CO with broad troughing influencing the Desert Southwest. The
trough becomes a bit more longwave like for the end of the week,
which could lead to a renewed chance for offshore flow with warmer
weather. This could lead to a period of elevated fire weather
conditions.

.AVIATION...
(00Z TAFS)
Issued at 453 PM PDT Sun Oct 11 2026
Mostly clear skies will persist through the TAF period as drier
air continues to filter in from the North. Strong onshore winds
will diminish over the next 3 hours before flipping to a light
offshore breeze overnight. Surface winds will return to a
moderate onshore breeze Monday afternoon.
Vicinity of SFO...High confidence in VFR conditions through the
TAF period. Strong westerly winds will weaken through the early
evening. A gentle NE wind is expected in the early morning, before
a moderate westerly breeze returns around midday.
SFO Bridge Approach...Similar to SFO.
Monterey Bay Terminals...VFR conditions are expected to persist,
but there is a better chance for some mid-level clouds through the
TAF period as some remnant moisture from Tropical Storm Rachel
wraps around from the East.

.MARINE...
(Tonight through next Friday)
Issued at 453 PM PDT Sun Oct 11 2026
Northerly flow is slowly easing over the coastal waters, but
hazardous conditions persist with fresh breezes to gale force
winds and rough seas. Strongest winds will be over the outer
waters north of Point Reyes. Moderate to longer period swells
continue to mix in leading to a confused sea state into next
week.

.BEACHES...
Issued at 1042 AM PDT Sun Oct 11 2026
Buoy reports this morning still indicated some solid swell
entering the coastal waters. As such, still seeing an energetic
the surf zone. Give the observed height and period isolated
breaking waves 18-20 ft are possible at favored break points. Long
period southerly swell will persist through the weekend, bringing
an increased risk of sneaker waves and strong rip currents. The
large tidal swings will also result in coastal erosion as water
and waves are brought farther up the beach than normal, especially
during high tide. Remain off jetties, piers, rocks, and other
waterside infrastructure as waves can sweep across the shoreline
without warning, pulling people into the sea. Remain out of the
water to avoid hazardous surf and strong rip currents and never
turn your back on the ocean!
