330 PM HST SAT APR 18 2026
DISCUSSION
A SMALL PULSE OF MEDIUM PERIOD SWELL ENERGY FROM THE NORTHWEST SHOULD
PRODUCE A SLIGHT BUMP IN NORTH FACING SURF HEIGHTS TONIGHT INTO SUNDAY
MORNING. A SMALL TO MODERATE, MEDIUM PERIOD NORTHWEST SWELL WILL MOVE
INTO THE REGION BY MONDAY NIGHT AND CONTINUE THROUGH WEDNESDAY. A
MODERATE, MEDIUM PERIOD NORTHEAST SWELL ARRIVES TUESDAY AND PEAKS ON
WEDNESDAY, BRINGING MODERATE SURF TO NORTH-FACING SHORES, BEFORE
SLOWLY DECLINING THROUGH THE END OF THE WEEK.
A MEDIUM-PERIOD SOUTH SWELL WILL CONTINUE TO FADE TONIGHT, ALLOWING
SURF ALONG SOUTH SHORES TO RETURN TO BACKGROUND LEVELS BY SUNDAY. A
SERIES OF OVERLAPPING SMALL SOUTH SWELLS WILL MOVE INTO THE REGION
INTO NEXT WEEK. SURF HEIGHTS ALONG EAST-FACING SHORES REMAIN ON THE
SMALLER SIDE DUE TO WEAKER TRADE WINDS UNTIL THE ARRIVAL OF THE
AFOREMENTIONED NORTHEAST SWELL ON TUESDAY. SMALL BACKGROUND ENERGY
FROM THE WEST WILL BE POSSIBLE, ESPECIALLY LATER IN THE WEEK, FROM
SEVERE TROPICAL STORM SINLAKU.
