.SHORT TERM...
Issued at 1220 PM PDT Fri Jun 26 2026
(This evening through Saturday night)

Radar shows ongoing light rain showers across the far interior areas 
as a cold front moves down, associated with the larger upper level 
low propagating across the PacNW. With troughing firmly in place, a 
deeper marine layer allowed for some coastal drizzle this morning 
for a few spots, now currently mixing out. High clouds associated 
with this system continue to move into the region, helping to 
keep interior areas a bit cooler today. Along with these clouds, cooler
850 mb temps will usher in 10-15 degree below normal surface 
temperatures for both this afternoon and Saturday. As the low 
moves slightly southward today and tomorrow, a tighter gradient 
will allow for a significant uptick in onshore winds both days, 
with gusts 50+ mph through west-east passes and mountain 
peaks...20-40 mph wind gusts elsewhere. With better moisture in 
the lower levels, the marine layer on Saturday will remain 
sufficiently deep, and another round of drizzle/light rain 
(<0.05") is expected in the morning.

Winds will increase not only across inland areas, but also over the 
waters. Gusts up to 30-40 kt will be possible with seas of 8 to 10 
ft. Marine hazards are currently in effect through Sunday morning, 
please see the marine discussion for further information.

An uptick in long period southerly swell will result in a high risk 
of rip currents and sneaker waves. Never turn your back to the 
ocean! Beach hazards will be in effect this weekend and into 
much of next week, see the beaches discussion for more
information.

.LONG TERM...
Issued at 1220 PM PDT Fri Jun 26 2026
(Sunday through next Thursday)

The aforementioned low will move up to Idaho/Montana beginning 
Sunday, but weak troughing will remain in place over California 
through at least the middle of next week as high pressure attempts 
to push in from the west. A very slow increase in heights will 
support the marine layer becoming more compressed each day, but 
could still make it relatively far inland with patchy fog for the 
coastal terrain through at least Tuesday. Temperatures will follow 
suit, slowly warming into the middle of the week, but generally 
should remain at or below normal through the forecast period. Model 
guidance has finally started to catch on to this cooler influence 
from the trough, but forecasted temperatures near the end of the 
period may still be a bit too high depending on how long it takes
for the ridge to push in.

.AVIATION...
(00Z TAFS)
Issued at 433 PM PDT Fri Jun 26 2026

Low clouds will continue to fill in further inland through this
evening. Gusty westerly winds will ease slightly tonight,
increasing again on Saturday afternoon across the region, mainly 
20-35 kts at TAF sites. MVFR/IFR conditions prevailing through
Saturday morning with pockets of BR/DZ 03-15Z Sat, which may 
reduce visibilities along the coast and some slightly more inland 
areas 4-6sm. CIGs scattering from the north to the south mid 
morning into the early afternoon hours. 

Vicinity of SFO...MVFR CIGs prevailing through mid Saturday
morning, locally IFR tonight, especially in areas of BR/DZ and vis
near 6sm. Winds will remain elevated but ease through the evening
with gusts near 15 knots. Cloud cover lifts and scatters into the
mid morning as gusty west winds return. Strong gusts build into 
Saturday afternoon, with around a 40% chance of wind gusts 
reaching 35 knots.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...Cloud cover will increase this evening
with MVFR conditions, locally IFR conditions in any BR/DZ 
overnight. Winds will reduce into the evening with elevated winds
returning by Saturday afternoon with gusts near 25 knots at 
times.

.MARINE...
(Today through Wednesday)
Issued at 1156 AM PDT Fri Jun 26 2026

Winds have reduced in the outer waters, but continue to be breezy
to gusty along the immediate coast. Winds across the waters will
reduce through the day but begin to strengthen again Saturday
afternoon. These strong winds and rough seas will result in
hazardous conditions for small craft across the waters at times
well into the work week. Expect gale force gusts to develop in the
northern outer waters and along coastal jet regions over the
weekend as well. Long period southwest swell will persist through
the extended forecast.

.BEACHES...
Issued at 110 AM PDT Fri Jun 26 2026

A Beach Hazards Statement has been issued for the Pacific Coast 
Beaches from Saturday morning through Wednesday morning as long 
period southerly swell returns to the coast, creating an increased
risk of sneaker waves and strong rip currents, especially for 
south and southwest facing beaches. Hazardous beach conditions are
advertised, specifically for moderate to steeply sloped beaches 
along the Pacific Coast of the North Bay, San Mateo, Santa Cruz 
counties. Sneaker waves will run up the beach much farther than 
other waves, potentially catching beachgoers by surprise and 
resulting in people being swept into the water. Rip currents are 
strong enough to pull the strongest swimmers away from shore. Swim
near a lifeguard if possible. Stay back from the beach, and away 
from jetties, piers, beachside rocks, and other infrastructure 
near the water. Never turn your back to the ocean!
