Forecast for Big Island Windward and Southeast

Forecast for Big Island Leeward

Swell Summary

Energy associated with the existing NNW swell is small and concentrated in the shorter periods favoring a slight downward adjustment to the surf numbers for N facing shores for this evening. Forerunners associated with a new moderate medium to long period NW swell have pinged on the NDBC offshore buoys this afternoon. This energy will build into the nearshore waters tonight into Sunday. Surf will build rapidly during the morning peaking near High Surf Advisory thresholds for N and W facing shores by Sunday afternoon. A combination of moderate NW and N swells will maintain elevated surf elevated through the first half of next week.

E shores remain tiny to small given the lack of trade winds but shorelines exposed to N swells may be slightly elevated through Wednesday. Surf along S shores will see an increase of short period wind wave chop mainly over the western islands this weekend associated with the passing front. A slight lull is expected Sunday before the next front approaches and increases the wind waves coming from the south.
