SYNOPSIS
BREEZY TRADES WITH MINIMAL SHOWER ACTIVITY CONFINED TO MAINLY
WINDWARD AREAS AND MAUKA SLOPES. MODEL GUIDANCE IS BEGINNING TO
HINT AT DEVELOPING NORTHWEST TROUGHING WHICH MAY INTRODUCE HIGHER
WIDESPREAD PRECIPITATION.
SHORT TERM UPDATE
ISSUED AT 955 AM HST WED APR 1 2026
NO SIGNIFICANT FORECAST CHANGES WERE MADE IN THE NEAR TERM. THE
ONLY MENTIONABLE ADJUSTMENT WERE TO TONIGHT THROUGH THURSDAY'S
COASTAL WINDS. LAST NIGHT'S ASCAT PASSES ACROSS THE WESTERN END
OF THE STATE HAVE VERIFIED STRONGER WINDS THROUGH ISLAND PASSES.
HIGH RESOLUTION MODELING IS ALSO ONBOARD WITH KEEPING THESE
CHANNEL WINDS STRONGER IN THE SHORT TERM, STRONGEST OVER MA'ALAEA
BAY AND THE PAILOLO AND ALENUIHAHA CHANNELS WHERE WINDS SHOULD
REMAIN AT SMALL CRAFT ADVISORY LEVELS. OVERALL TRADES WILL FADE A
BIT FROM FRIDAY AND THE WEEKEND AS THE PRESSURE GRADIENT RELAXES
FROM A WEAK SURFACE HIGH MOVING ONTO THE U.S. MAINLAND WEST COAST.
UPPER RIDGING NOSING IN FROM THE WEST WILL GUARANTEE ANOTHER
PLEASANT DAY FOR THE MAJORITY OF THE ALOHA STATE. PARTIALLY
CLOUDY SKIES AND CONTINUED DRY CONDITIONS RULE (UPPER 50 TO LOW
60 F DEW POINTS). THE AFTERNOON WILL WARM INTO THE AVERAGE MID
70S ALONG AND NEAR THE COAST, INTO THE 60S ABOVE 2 KFT. TONIGHT'S
FULL MOON SHOULD BE SEEN BY MANY WITH FREQUENT LUNAR PEEKS BETWEEN
PASSING CLOUDS. EVENING BREEZY COASTAL TRADES AND LAND BREEZY
WITHIN WIND-SHELTERED INTERIOR LOCALS AS TEMPERATURES QUICKLY COOL
BACK INTO THE MIDDLE 60S TO LOW 70S SHORTLY AFTER SUNSET. LOCAL
SOUNDINGS DEPICT A MOISTENED LOWER 7 KFT BOUNDARY LAYER CAPPED BY
BONE DRY MID TO UPPER LAYER AIR. THUS, ANY VERY LIGHT
PRECIPITATION WILL PRIMARILY FOCUS ALONG EASTERN-FACING UPSLOPE
MAUKA AND HIGHER INTERIOR ELEVATION WITH THE OCCASIONAL OFFSHORE
WEAK SHOWER PASSING OVER WINDWARD COASTAL AREAS.

MARINE
ISSUED AT 955 AM HST WED APR 1 2026
HIGH PRESSURE NORTH OF HAWAII WILL SHIFT EASTWARD BY THE WEEK,
CAUSING TRADE WINDS TO DIMINISH. A SMALL CRAFT ADVISORY IS IN
EFFECT FOR THE TYPICALLY WINDIER WATERS AROUND MAUI COUNTY AND THE
BIG ISLAND THROUGH THURSDAY NIGHT.
MODERATE NORTH AND EAST-FACING SHORE SURF CONTINUES TO BE GENERATED BY
A SHORT PERIOD NORTHEAST (040 DEGREE) SWELL WHICH WILL GRADUALLY
DIMINISH THROUGH TONIGHT. BREEZY WINDS WILL ALSO BRING ROUGH
CONDITIONS TO EAST FACING SHORES TODAY, BUT WILL DECLINE THROUGH THE
REST OF THE WEEK.
THE NEXT SMALL, MEDIUM-PERIOD NORTHWEST SWELL WILL ARRIVE THIS
WEEKEND TO BRING A SMALL BUMP IN SURF FOR WEST-FACING SHORES. ALONG
SOUTH- FACING SHORES, EXPECT SMALL REINFORCEMENTS TO SUSTAIN SMALL
SURF THROUGH THE WEEK.
