923 AM HST SAT JUL 11 2026
SYNOPSIS
STRONG HIGH PRESSURE FAR NORTH OF THE STATE WILL PRODUCE BREEZY
TRADE WINDS THROUGH THE WEEKEND AND INTO THE FIRST HALF OF NEXT
WEEK. A SLIGHT WEAKENING AND VEERING OF THE TRADE WINDS IS
POSSIBLE DURING THE SECOND HALF OF NEXT WEEK AS THE HIGH PRESSURE
MOVES NORTHEAST AND LOW PRESSURE POTENTIALLY DEVELOPS IN THE
TROPICS TO THE SSW. AN INCREASE IN MOISTURE WILL BRING ENHANCED
SHOWERS TO WINDWARD AND MAUKA LOCATIONS SATURDAY NIGHT INTO SUNDAY
MORNING. THE NEXT PLUME OF MOISTURE COULD THEN ARRIVE BY THE
MIDDLE OF NEXT WEEK.
SHORT TERM UPDATE
RADAR SHOWS TYPICAL TRADE WIND SHOWERS THIS MORNING, AND SATELLITE
INDICATES CLOUDS ARE MAINLY WINDWARD AND MAUKA. WINDS REMAIN
BREEZY, WITH SUSTAINED WINDS AVERAGING 10 TO 15 MPH WITH THE
TYPICAL GUSTY SPOTS A LITTLE HIGHER. NO CHANGES ARE PLANNED TO THE
FORECAST THIS MORNING, AS EVERYTHING IS HANDLED WELL BY THE
CURRENT FORECAST.

MODERATE TO LOCALLY BREEZY TRADES CONTINUE ACROSS THE HAWAIIAN
ISLANDS, WITH POCKETS OF EMBEDDED LIGHT TO MODERATE SHOWER
ACTIVITY EXPECTED TO IMPACT WINDWARD SITES AT TIMES, OCCASIONALLY
SPILLING OVER INTO LEEWARD AREAS. EXPECT VFR CONDITIONS TO PREVAIL
ACROSS MOST LOCATIONS, WITH OCCASIONAL LOCALIZED MVFR CONDITIONS
IN ASSOCIATION WITH LOW CLOUDS AND SHOWER ACTIVITY.
AIRMET TANGO REMAINS IN EFFECT FOR MODERATE LOW-LEVEL TURBULENCE
OVER AND DOWNWIND OF TERRAIN FOR ALL ISLANDS. THIS AIRMET WILL
LIKELY CONTINUE AS THIS ONGOING TRADE WIND PATTERN PERSISTS.
MARINE
STRONG HIGH PRESSURE WILL REMAIN ANCHORED FAR NORTH OF THE STATE,
DRIVING FRESH TO STRONG TRADE WINDS INTO THE REGION. A SMALL CRAFT
ADVISORY (SCA) REMAINS IN EFFECT ACROSS ALL HAWAIIAN COASTAL
WATERS THROUGH SUNDAY AFTERNOON. THE TRADES WILL WEAKEN SLIGHTLY
HEADING INTO EARLY NEXT WEEK, WHICH WILL LIKELY LEAD TO THE SCA
BEING SCALED BACK TO THE WINDIER WATERS AND CHANNELS AROUND MAUI
COUNTY AND THE BIG ISLAND.
THE CURRENT SMALL MEDIUM-PERIOD SOUTH-SOUTHWEST (190-200 DEGREES)
SWELL WILL HOLD TODAY JUST BELOW THE SUMMER AVERAGE. A SMALL TO
MODERATE, LONG-PERIOD SOUTHWEST SWELL (220 DEGREES) IS EXPECTED
TO FILL IN LATER TODAY THROUGH MONDAY, WHICH WILL BOOST SURF
THROUGH EARLY NEXT WEEK.
SURF ALONG EAST-FACING SHORES WILL REMAIN ROUGH AND CHOPPY
THROUGH THE FORECAST PERIOD AS FRESH TO STRONG TRADES HOLD. A
SERIES OF SMALL, MODERATE PERIOD WEST (270 TO 280 DEGREES) SWELLS
WILL HOLD INTO EARLY NEXT WEEK, FOLLOWED BY A SMALL LONG-PERIOD
WEST SWELL HEADING INTO MIDWEEK, SOURCED FROM TYPHOON BAVI IN THE
FAR WESTERN PACIFIC. NO SIGNIFICANT NORTH OR NORTHWEST SWELLS ARE
EXPECTED, SO SURF ALONG NORTH- FACING SHORES IS EXPECTED TO
REMAIN FLAT TO TINY.
HIGHER THAN NORMAL HIGH TIDES ARE EXPECTED, WITH COASTAL FLOODING
POSSIBLE DUE TO UPCOMING KING TIDES, PARTICULARLY MONDAY THROUGH
WEDNESDAY. INTERESTS IMMEDIATELY ALONG THE COASTS IN LOW-LYING OR
VULNERABLE AREAS SHOULD CONTINUE TO MONITOR FORECASTS.
