.SHORT TERM...
Issued at 223 PM PDT Sat Jul 26 2025
(This evening through Sunday)

It is deja vu today with the stratus cleared out inland this
afternoon, lingering at the coastal regions and flowing into the
northern San Francisco Bay, expanding inland stratus this evening
and overnight, breezy onshore winds through the evening hours,
and temperatures remaining cooler than seasonal averages across
the region. High temperatures today range from the lower 70s to
lower 80s inland, up to the upper 80s in the warmest spots of
southern Monterey County, the middle 60s to lower 70s near the
Bays, and the upper 50s to lower 60s at the Pacific coast. Low
temperatures hover in the 50s throughout the region, while highs
on Sunday will be similar to today`s with a few degrees of warming
inland.

.LONG TERM...
Issued at 148 PM PDT Sat Jul 26 2025
(Sunday night through next Friday)

The forecast will  be mostly on repeat this period. The marine layer
is expected to compress Sunday into early next week falling to
around 1000ft +/- a couple of hundred feet. This will keep the
stratus creeping too far inland; however, a deepening marine looks
to return mid week. What does that mean, No Sky July continues and
we`ll start off August as Fogust. Cloudy nights, stratus retreating
to the coast during the day, and near seasonal to below seasonal
temperatures.

.AVIATION...
(06Z TAFS)
Issued at 958 PM PDT Sat Jul 26 2025

MVFR-IFR stratus expands from the coast into the Bay Area valleys
and the Monterey Bay region. Stratus will mix out across the inland
regions through Sunday morning and early afternoon while the coastal
areas remain socked in. Breezy onshore winds continue to diminish
over the next few hours, becoming light through Sunday morning
before resuming in the afternoon. Sunday evening, expect some inland
stratus to return although gradual compression of the marine layer
might limit the inland extent of the ceilings.

Vicinity of SFO... MVFR-IFR stratus through Sunday morning. Stratus
dissipates early Sunday afternoon, with the terminal remaining VFR
for a brief period before getting socked in again during the late
afternoon and early evening hours. Even then, expect the stratus
deck to lurk just to the north of the terminal. Breezy and gusty
west winds continue to diminish through the next few hours, becoming
light through Sunday morning before resuming in the afternoon.

SFO Bridge Approach... Similar to SFO.

Monterey Bay Terminals... MVFR-IFR through Sunday morning, with the
inland regions clearing out by the early afternoon. Low probability
(20-30%) that MRY remains socked in through the day, but model
output currently shows a brief period of clear skies in the
afternoon hours. Stratus returns in the early evening. Light winds
continue overnight before breezy onshore flow returns Sunday
afternoon.

.MARINE...
(Tonight through next Friday)
Issued at 807 PM PDT Sat Jul 26 2025

High pressure maintains northerly flow over the coastal waters
through the next week. Winds will increase locally on Sunday
afternoon north of Point Reyes and south of Point Sur. Moderate
seas prevail through the weekend then gradually increase beginning
Monday.
