Swell Summary
A small to moderate size, medium period northwest swell is filling around Kauai and Oahu today. Nearshore buoys are observing a 4 to 6 foot swell peaking in the 14 to 16 second bands this afternoon. This swell will result in slightly over head to double head high surf within the highest sets along many north and west-facing shores through the early Tuesday morning hours. The swell will decline from Tuesday morning into Wednesday. A larger moderate size north northwest swell will arrive Thursday. If this swell comes in as guidance is currently suggesting, surf will achieve High Surf Advisory heights along many of the north and west-facing shores of the smaller islands Thursday night and Friday.
East-facing shore surf will remain somewhat rough tonight due to recent strong east trades over and upstream of the islands. As winds fall off in the coming days, responding east chop will significantly drop off.
Surf along south-facing shores will remain small and mostly at background levels through Thursday. A series of small overlapping south swells could increase surf up to seasonal levels from Friday through the weekend.
