.SHORT TERM...
Issued at 1204 AM PDT Tue Jun 2 2026
(Today and tonight)

Expecting areas of dense fog overnight along the Monterey Bay and 
Big Sur coastline, similar to early Monday morning in the pre-dawn 
hours with a more robust marine layer getting some assistance 
pushing inland from a weak upper trough that will continue to shift 
south toward SoCal for the remainder of the overnight and today. 
Meanwhile, with weak upper level ridging just to our north, leaves 
the Bay Area and Central Coast under unorganized H30 jet flow early 
this morning that begins to increase and become more organized 
throughout the day. Temperatures today will be near or slightly 
cooler than Mondays highs. Higher elevations in the far North Bay 
tonight under the influence of the east shifting upper ridge will 
once again see warmer than normal temperatures from thermal belting, 
while similarly to the far south in higher elevations of the Santa 
Lucias in southern Monterey County the upper low helps promote a 
weak fetch of offshore flow and thermal belting, an interesting 
pattern with H85 temperatures roughly in the 75th percentile for 
this time of year. Otherwise overnight lows into Wednesday will be
in the low to mid-50s for lower lying areas both near the coast 
and inland.

.LONG TERM...
Issued at 1204 AM PDT Tue Jun 2 2026
(Wednesday through Monday)

The remainder of the work week will only have slight fluctuations in 
daily temperatures as the upper level low organizes in the Gulf of 
Alaska with its associated trough deepening southward toward out 
latitude, arriving in earnest later Friday, and lowering our 
temperatures 5-10 degrees below normal for the weekend into the 
beginning of next week. The troughing pattern appears to persist 
past the current extended forecast, however the forecast continues
to remain dry, but pockets of coastal drizzle and fog may be a 
nuisance up and down our Pacific coastline each night and early 
morning.

.AVIATION...
(06Z TAFS)
Issued at 1001 PM PDT Mon Jun 1 2026

Stratus is moving back in along the coast and is expected to move 
into the interior overnight. Moderate confidence that localized fog 
will develop along the coast with IFR-LIFR conditions expected to 
impact HAF, MRY, and SNS. CIGs and VIS are expected to be slightly 
higher across the interior terminals where most sites stay IFR-MVFR 
tonight. HRRR guidance shows a much wider fog footprint along the 
Bay shoreline (impacting STS and OAK) compared to other models. The 
HRRR appears to be an outlier but ensembles generally agree that 
visibilities will drop overnight (ranging from 2-5 SM across the 
interior). Winds are easing across the region but gusty onshore 
winds return again during the afternoon/evening tomorrow.

Vicinity of SFO...Breezy onshore winds continue to decrease 
overnight before gusty onshore winds return tomorrow afternoon and 
evening. Moderate to high confidence in MVFR CIGs overnight with 
increasing confidence that IFR conditions will develop during the 
early morning. CIGs clear by late morning with VFR conditions 
persisting the rest of the day. LAMP guidance suggests a brief 
period of LIFR CIGs are possible between 12-16Z but confidence is 
low in this scenario.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...IFR to LIFR CIGs expected overnight with 
dense fog possible during the early morning hours. CIGs have been 
trending downwards over the last few hours with WVI reporting LIFR 
CIGs as of 05Z. This is increasing confidence in LIFR CIGs 
developing more rapidly at MRY and SNS and continuing for much of 
the night. CIGs look to clear by late morning before MVFR-IFR CIGs 
return early (00-03Z). The current TAFs are slightly optimistic with 
regards to clearing tomorrow afternoon. HREF and LAMP guidance both 
offer more pessimistic forecasts with MVFR CIGs persisting at MRY 
throughout the day. Breezy onshore winds return during the day with 
lighter winds expected overnight.&&

.MARINE...
(Tonight through next Sunday)
Issued at 1001 PM PDT Mon Jun 1 2026

Light to moderate winds continue into early Tuesday with seas
abating. Winds increase Tuesday with strong northerly winds
returning by late Tuesday with gale force gusts returning mid
week and seas building starting mid to late week. Gale force
gusts and elevated seas will continue through the end of the
forecast period.

.BEACHES...
Issued at 1229 AM PDT Mon Jun 1 2026

A Beach Hazards Statement remains in effect today through 5 AM
Tuesday morning due to an increased risk for sneaker waves and
strong rip currents caused by a long period southwest swell. On
the buoys, this swell is being masked by stronger northwest swell
waves, but careful analysis of the wave spectrum at the Point
Reyes and Point Sur buoys reveals a southwest swell around 1 to 2
feet high with a period of 20 seconds. These long period swells 
result in increased risk of sneaker waves, potentially deadly 
waves which surge much further up the beach than expected and 
sweep unaware beachgoers into the ocean, and strong rip currents 
that can sweep the strongest swimmers away from shore. Never turn 
your back to the ocean! Inexperienced swimmers should stay away  
from the water. Observe the waves for 20 minutes before moving 
closer. Swim near a lifeguard if possible, and if caught in a rip 
current, swim parallel to the coast away from the current, and 
then at an angle to shore.
