.SHORT TERM...
Issued at 1245 AM PDT Fri Jun 5 2026
(Today and tonight)

Satellite shows a few patches of cirrus clouds and coastal stratus
clouds otherwise it's clear. Coastal haze and strengthened cold 
water upwelling has returned in response to gusty northwest winds 
over the coastal waters. Dry weather continues under a strong high
pressure system. The northerly ACV-SFO pressure gradient is strong
at 8.3 mb and the onshore SFO-SAC pressure gradient is moderate at
2.9 mb.

Expect sun with daytime highs in the upper 60s/70s coastside to 
the 80s/90s well inland today. Mainly clear with low temperatures 
cooling to the 50s tonight.

.LONG TERM...
Issued at 1245 AM PDT Fri Jun 5 2026
(Saturday through Thursday)

An upper level trough returns Saturday and Sunday. This will 
bring cooler temperatures Saturday and Sunday. Expect dry weather
with more comfortable outdoor daytime temperatures for the 
weekend. Model output has varied some on the chance of rain for 
the Bay Area early next week, nonetheless an active pattern favors
a rain chance. Rain may be mixed with drizzle. After this 
timeframe a strengthening 500 mb ridge of high pressure develops 
with a warming and drying trend late next week.

.MARINE...
(Tonight through next Tuesday)
Issued at 242 PM PDT Thu Jun 4 2026

Hazardous conditions for small craft continue through the 
weekend. Gale force gusts are expected across the outer waters and
along the coastal jet regions. Moderate to rough seas will 
continue to build through Friday to become rough to very rough for
the inner and outer waters through the weekend. Conditions will 
gradually begin to improve Monday as northwesterly winds diminish 
to become fresh to strong and seas subside to become moderate.

.BEACHES...
Issued at 242 PM PDT Thu Jun 4 2026

A Beach Hazards Statement will go into effect at 3 AM Friday through 
9 AM Saturday due to an increased risk of sneaker waves and strong 
rip currents. Long period southwest swell is approaching the Pacific 
coast, with periods of 17 to 18 seconds and a height of around 3 
feet in the open waters. 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 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.
