.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.

.MARINE...
(Today through Friday)
Issued at 1039 AM PDT Sun Oct 11 2026

Hazardous conditions persist over the coastal waters due to fresh
breezes to gale force winds and rough seas. Strongest winds will
be over the outer waters north of Pigeon Point. The strong winds
and long period southerly swell will result in a confused sea
state into the beginning of 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!
