SURF ZONE FORECAST FOR HAWAII
NATIONAL WEATHER SERVICE HONOLULU HI
329 PM HST FRI APR 18 2025
DISCUSSION
A LINGERING NORTH-NORTHWEST SWELL THAT PEAKED LAST NIGHT WILL
CONTINUE ITS GRADUAL DECLINE THROUGH SATURDAY. ON SUNDAY,
SURF ALONG NORTH AND WEST FACING SHORES WILL DIP BELOW AVERAGE,
THEN REMAIN SO WELL INTO NEXT WEEK. GUIDANCE DOES DEPICT A GALE
FORMING ON MONDAY NEAR THE KURILS, THEN TRACKING NORTHEAST TO THE
WESTERN ALEUTIANS BY WEDNESDAY. IF THIS MATERIALIZES, HAWAII COULD
EXPERIENCE AN UPTICK IN THE NORTHWEST SWELL NEXT WEEKEND.
SURF ALONG EAST FACING SHORES WILL REMAIN BELOW THE APRIL AVERAGE
THROUGH MOST OF NEXT WEEK DUE TO THE LACK OF CONSISTENT TRADE
WIND FLOW.
A SMALL LONG PERIOD BACKGROUND SOUTH SWELL WILL MOVE THROUGH THIS
WEEKEND, BUT WILL HAVE LITTLE IMPACT ON SURF HEIGHTS. A LARGER
PULSE OF LONG-PERIOD SOUTH- SOUTHWEST SWELL IS EXPECTED FOR THE
COMING WEEK.
MEANWHILE, A PASSING UPPER LEVEL DISTURBANCE HAS TRIGGERED
ISOLATED TO SCATTERED THUNDERSTORMS ACROSS MUCH OF THE STATE.
THE POTENTIAL FOR STRONG THUNDERSTORMS WILL PERSIST THROUGH TONIGHT
AND POSSIBLY TOMORROW.
