346 AM HST SAT APR 19 2025
DISCUSSION
A MODERATE, MEDIUM PERIOD NORTH-NORTHWEST SWELL HAS SHIFTED MORE
NORTHERLY AND WILL CONTINUE TO GRADUALLY TREND DOWN THROUGH
SUNDAY, PRODUCING BELOW AVERAGE SURF ALONG NORTH AND WEST FACING
SHORES. A TINY, LONG PERIOD NORTHWEST SWELL MAY FILL IN MONDAY
INTO TUESDAY BEFORE SUBSIDING WEDNESDAY, KEEPING SURF FROM GOING
FLAT. IN THE LONG RANGE, GUIDANCE DOES DEPICT A GALE FORMING
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 THE WEEKEND. EAST SHORE SURF COULD TREND DOWN TO TINY
LEVELS BY MID WEEK AS SOUTHERLY WINDS TAKE OVER.
A TINY, LONG PERIOD SOUTH SWELL WILL MOVE THROUGH THIS WEEKEND THAT
WILL PROVIDE A SMALL BOOST IN SURF ALONG SOUTH FACING SHORES. A
LARGER, LONG- PERIOD SOUTH- SOUTHWEST SWELL IS EXPECTED TO FILL IN
MONDAY INTO TUESDAY THAT COULD PRODUCE NEAR TO ABOVE AVERAGE SURF
ALONG SOUTH FACING SHOWERS.
