SHORT TERM
ISSUED AT 110 AM PDT FRI JUN 26 2026 (TONIGHT THROUGH SATURDAY)
MARINE LAYER HAS BEGUN TO MOVE INLAND FOR MANY COASTAL CITIES. IT
WILL PERSIST THROUGH THE NIGHT INTO THE DAY TODAY WITH MOST OF THE
AREA PARTLY TO MOSTLY CLOUDY. THE MARINE LAYER IS DEEPENING CLOSER
TO 2000-2500 FT, SIGNIFICANT ENOUGH FOR PATCHY DRIZZLE THIS MORNING
ALONG THE PACIFIC COAST. HIGH CLOUDS WILL CONTINUE TO MOVE INTO THE
AREA OF THE THE TROUGH.
HIGH PRESSURE THAT BROUGHT ABOVE NORMAL TEMPERATURES TO THE AREA HAS
BEEN REPLACED BY A DEEPENING TROUGH FROM THE PACIFIC NORTHWEST.
ELEVATED WINDS OBSERVED YESTERDAY STRENGTHEN TODAY AS THE GRADIENT
CONTINUES TO TIGHTEN AND THE FRONT MOVES THROUGH THE AREA. EAST-
WEST PASSES COULD SEE GUSTS UP TO 50+ MPH WITH MANY OTHER LOCATIONS
GUSTING UP TO 25-35 MPH. FOLLOWING THE PASSAGE OF THE FRONT,
TEMPERATURES COOLDOWN SIGNIFICANTLY FALLING 4-10 DEGREES COMPARED TO
YESTERDAY FOR MOST LOCATIONS OUTSIDE OF THE IMMEDIATE COAST. LOW
CLOUDS WILL LIKELY STRUGGLE TO CLEAR OUT THIS AFTERNOON WITH
DECENT MOISTURE IN THE LOWER LEVELS AND HIGH CLOUDS WILL MOVE IN
FROM NORTH TO SOUTH.
ADDITIONAL COOLING IS EXPECTED FOR SATURDAY WITH AN EVEN DEEPER
MARINE LAYER USHERING IN WIDESPREAD COASTAL DRIZZLE AND POCKETS OF
LIGHT RAIN STARTING AS EARLY AS LATE FRIDAY NIGHT/ EARLY SATURDAY
MORNING. SATURDAY SHOULD BE THE COOLEST DAY OF THE FORECAST WITH
CLOUDS STRUGGLING TO MIX OUT IN THE AFTERNOON AND A SLOWER TREND TO
THE MOVEMENT OF THE LOW. WHILE IT MEANDERS ALONG THE BORDERS OF
CA/NV/OR, HIGHS ON SATURDAY SHOULD ONLY REACH THE 50S AND 60S FOR
MOST SPOTS, WITH LOW TO MID 70S FOR INTERIOR AREAS, GENERALLY 10-15
DEGREES BELOW NORMAL.
THE WINDS WILL INCREASE NOT JUST FOR INLAND SPOTS, BUT ALSO FOR THE
COASTAL WATERS. MORE INFORMATION CAN BE FOUND IN THE MARINE SECTION
BELOW.
LONG TERM
ISSUED AT 110 AM PDT FRI JUN 26 2026 (SATURDAY NIGHT THROUGH NEXT
THURSDAY)
THE PATTERN BEGINS TO SHIFT SUNDAY AS THE AFOREMENTIONED LOW WEAKENS
AND STARTS TO MOVE UP INTO IDAHO AND MONTANA AND HEIGHTS SLOWLY
INCREASE. WITH THIS, THE MARINE LAYER WILL BEGIN TO COMPRESS A BIT
EACH DAY INTO EARLY NEXT WEEK, AND TEMPERATURES WILL SLOWLY WARM
BACK TOWARDS NORMAL. GENERAL MODEL TRENDS ARE PUSHING TEMPERATURES
HIGHER FOR NEXT WEEK, BUT ENSEMBLE GUIDANCE CONTINUES TO FAVOR WEAK
TROUGHING PREVAILING WHICH WOULD KEEP US A BIT COOLER. SHOULD THE
LATTER PREVAIL, THE COASTAL WATERS MAY CONTINUE TO BE IMPACTED BY
GUSTY NORTHWEST WINDS THROUGH MUCH OF THE WEEK, WITH MARINE HAZARDS
POTENTIALLY PREVAILING.
THE CONCERN FOR HAZARDOUS BEACH CONDITIONS RETURN FOR PACIFIC COAST
BEACHES THIS WEEKEND AS LONG PERIOD SOUTHERLY SWELLS RETURN. MORE
INFORMATION BELOW IN BEACHES, BUT REMEMBER TO NEVER TURN YOUR
BACK TO THE OCEAN!

WINDS HAVE REDUCED IN THE OUTER WATERS, BUT CONTINUE TO BE BREEZY
TO GUSTY ALONG THE IMMEDIATE COAST. WINDS ACROSS THE WATERS WILL
REDUCE THROUGH THE DAY BUT BEGIN TO STRENGTHEN AGAIN SATURDAY
AFTERNOON. 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 OVER THE
WEEKEND AS WELL. LONG PERIOD SOUTHWEST SWELL WILL PERSIST THROUGH

BEACHES
ISSUED AT 110 AM PDT FRI JUN 26 2026
A BEACH HAZARDS STATEMENT HAS BEEN ISSUED FOR THE PACIFIC COAST
BEACHES FROM SATURDAY MORNING 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!
