.SHORT TERM...

(This evening through Tuesday night)

GOES-West visible satellite imagery reveals marine stratus
hugging the Monterey Bay shoreline and points south while the vast
majority of the San Francisco Bay Area is mostly clear. As of
noon PDT, temperatures are generally running within a few to
several degrees of what they were compared to this time yesterday.
By the time the afternoon concludes, expect temperatures along to
coast to peak in the upper-50s to 60s, warming to the 70s to to
around 90 for inland communities. All-in-all, a very typical
summer day.

Western North America has been dominated by a long-wave trough
with upper-low centered over the Northern Rockies. This troughing
pattern will continue through much of the week with onshore flow
prevailing for the Golden State. This will result in the usual
marine stratus for coastal communities and near- to slightly
cooler than seasonable temperatures inland. While inland
temperatures are forecast to rise by a few degrees from Monday to
Tuesday, coastal communities may reverse and cool as a result of
the continued onshore flow. That said, forecast HeakRisk for the
Bay Area and Central Coast will remain in the Low (green) to Minor
(yellow) categories through the middle of the week.

The risk of minor coastal flooding continues through Monday night
along low-lying areas in the Pacific coast and the San Francisco
and San Pablo Bays. The combination of thermal expansion within
the Pacific ocean, a full moon on Monday, and southerly swell will
account for a little over half a foot of surge over the
astronomical tide. In addition, long-period southerly swell will
continue to increase the risk for sneaker waves and strong rip
currents along the Pacific coast, particularly at south and
southwest facing beaches. A Beach Hazards Statement remains in
effect through Wednesday morning, see the BEACHES section for more
details. Never turn your back to the ocean!

.LONG TERM...

(Wednesday through next Sunday)

The long-wave trough will gradually loose its grip over western
North America by the end of the work week as a zonal flow re-
establishes over the region. This will result in rebounding
temperatures by Friday and Saturday with high returning to the
90s for the warmest interior communities. Cluster analysis of the
ensembles suggests a building ridge over the Desert Southwest by
early next week. There is still some variance in possible
solutions, but something worth keeping an eye on for next week.
Latest Climate Prediction Center guidance does give increased
likelihood of above normal temperatures in the 8 to 14 day
outlook.

.AVIATION...
(06Z TAFS)
Issued at 817 PM PDT Mon Jun 29 2026

Moderate to high confidence in MVFR/IFR ceilings developing at
bayshore and coastal terminals respectively tonight; higher
confidence in CIGs coming in early morning hours around sunrise
for areas near SFO and OAK. Diurnal winds will prevail. CIGs fill
back in around the bay regions Tuesday night.

Vicinity of SFO...VFR with elevated winds out of the northwest
through the evening. Moderate confidence on a ceiling returning
near 11-13z, with MVFR more likely. Reasonable best case scenario
is a donut hole develops over the terminal with stratus remaining
confined on the north and west sides. Stratus not sticking around
for too long, becoming VFR after 16z with elevated winds
returning in the afternoon with gusts near 25 kts at times.

SFO Bridge Approach...The San Mateo Bridge Approach has low
probabilities (<30%) for developing a ceiling below FL045.
Reasonable best case scenario is clouds remain confined to the
terminal and northward.

Vicinity of SJC and OAK...High confidence in VFR and diurnal
winds prevailing at SJC. Moderate confidence in an MVFR ceiling
developing at OAK tonight via a stratus feed through the Golden
Gate Gap between 11-17z. VFR into Tuesday afternoon/evening with
westerly winds for both sites. CIGs returing to OAK later Tuesday
night with lower confidence on timing.

Monterey Bay Terminals...MVFR/IFR cigs will cover both terminals
through the night. Clearing looking likely for both terminals
Tuesday 16-18z, highest confidence at SNS. Lighter westerly winds
tonight becoming elevated with gusts near 20 kts by Tuesday
afternoon. Low to moderate confidence on cigs returning a bit
earlier Tuesday evening between 03-05z.

.MARINE...
(Tonight through next Sunday)
Issued at 817 PM PDT Mon Jun 29 2026

Strong northerly breezes will continue through Friday for the
outer waters and the coastal jet region of Point Reyes. This will
create hazardous conditions for small craft. Frequent gale force
gusts are expected across the northern outer waters and along the
Point Reyes coastal jet region through Wednesday, a bit weaker
Thursday and Friday. Moderate northerly breezes will prevail
elsewhere. Rough to very rough seas will continue through
Wednesday before abating to become moderate to rough Thursday into
Friday.

.BEACHES...
Issued at 236 PM PDT Mon Jun 29 2026

A Beach Hazards Statement remains in effect for Pacific Coast
beaches through 5 AM Wednesday. Long period southerly swell will
create an increased risk of sneaker waves and strong rip currents.
This will be especially true for south and southwest facing beaches
with moderate to steep slopes along the North Bay, San Francisco
Peninsula, and Santa Cruz coasts. Sneaker waves can sweep across the
shoreline without warning, pulling people into the  sea from rocks,
jetties and beaches. Dangerous swimming and surfing conditions and
localized beach erosion can be expected. Stay off of jetties, piers,
rocks, and other waterside infrastructure. Remain out of the water
to avoid hazardous surf and NEVER turn your back on the ocean.
Monitor local weather, surf and tide forecasts at
www.weather.gov/mtr.
