Surf along north facing shores will remain small today as the current west-northwest swell continues to gradually decline. Surf is expected to build rapidly Saturday with long period forerunners of a large northwest (330 degree) swell potentially reaching the offshore buoys by this evening. This swell will likely peak Saturday evening, producing surf near High Surf Warning (HSW) levels along north and some west facing shores. Surf will remain elevated on Sunday before an even larger long period northwest (320-330 degree) swell will build through the day on Monday and hold through Tuesday, likely above the HSW thresholds. Surf will likely remain elevated through the middle of next week.

Surf along east facing shores will remain small through the weekend as winds over and upwind of Hawaii remain weak. Some increase in east shore surf is possible early next week as a cold front moves down the island chain. Along south shores, surf will remain very small through the forecast period.
