.SHORT TERM...
Issued at 1225 AM PDT Sun Jun 28 2026 (Tonight through Monday)

An upper level trough that has been moving across the Pacific
Northwest will move out of the area today. This will keep the 
marine layer compressed with mostly clear skies by the afternoon. 
High temperatures will rise 5-10 degrees from today as a result, 
with 60s along the coast, upper 60s to 70s along the Bay 
shoreline, and 70s to low 80s in the interior. HeatRisk is 
expected to remain Minor even with the increase in temperatures. 
Onshore winds will become breezy once again in the afternoon and 
evening, but weaker than yesterday with gusts 15-30 mph, except 
up to 40 mph through gaps/passes. Stratus should increase tonight,
but the shallow marine layer will limit inland development.

Along the Pacific coastal beaches, there is a possibility for 
marginal coastal flooding. Due to the upcoming full moon (Monday), 
thermal expansion of Pacific waters, and southerly swells, 
coastal flooding for low lying beaches at predominantly south 
facing beaches is possible at high tides through Monday. 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 through the weekend and into much 
of next week, see the beaches discussion for more information.

.LONG TERM...
Issued at 1225 AM PDT Sun Jun 28 2026 (Monday night through next 
Saturday)

As an upper level ridge over the Eastern Pacific pushes inland
Monday, temperatures will continue to rise for interior areas.
Temperatures in the coastal areas will remain fairly similar to
Sunday. The warming trend will be halted Tuesday as another upper
trough moves into the Pacific Northwest. This will bring cooler, 
below normal temperatures once again by Wednesday and Thursday as 
the trough ushers in cooler air aloft. Onshore flow will also 
increase along with the potential for a deeper marine layer and 
coastal drizzle. Onshore winds will be breezy to windy each 
afternoon and evening. By Friday, ensembles are more split on the 
evolution of the pattern, but ridging becomes a possibility. This 
is reflected in the forecast by an uptick in temperatures.

.AVIATION...
(06Z TAFS) Issued at 836 PM PDT Sat Jun 27 2026

Mostly clear skies will continue through the TAF period for northern 
areas. Elevated winds this evening will ease some into the night and 
early morning. Cloud cover will fill in a bit more over the Monterey 
Bay with MVFR CIGs tonight, eroding into the mid morning on Sunday, 
leading to widespread VFR. Onshore winds increase again Sunday 
afternoon, though not as strong as today. MVFR conditions returning 
to the Monterey Bay region and areas along the immediate coast 
Sunday evening and night.

Vicinity of SFO...Mostly clear through the TAF period. Winds will 
remain elevated into the night; winds increasing near 25 kts on 
Sunday afternoon. Confidence increasing VFR conditions remaining 
through Sunday night. 

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...Winds gusting near 20-25 kts the next few 
hours with lighter winds overnight. MVFR CIGs will continue to fill 
in overnight. These CIGs look to scatter into mid Sunday morning (15-
16z) with weaker onshore winds in the afternoon. MVFR CIGs filling 
in again around 03-06z Mon. with moderate to high confidence on 
timing and occurrence.

.MARINE...
(Tonight through next Friday) Issued at 837 PM PDT Sat Jun 27 2026

Stronger winds will continue at times through the night, ease 
slightly on Sunday morning and then increase again Sunday evening 
and night. 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 as well. Long 
period southwest swell will persist through the extended forecast.

.BEACHES...
Updated at 1225 AM PDT Sun Jun 28 2026

A Beach Hazards Statement remains in effect for the Pacific Coast
Beaches 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!
