Forecast for Big Island Leeward

Swell Summary

A small long period west northwest swell will continue to fill in today. The westerly direction of this swell will allow Kauai to block some of it from reaching the central islands. Meanwhile, a small short period northwest swell will fill in tonight, then linger through Wednesday and Thursday.

A longer period west northwest swell is expected to fill in late Thursday and Thursday night, peak late Friday and Friday night, then lower gradually over the weekend. The initial pulse from this swell may be somewhat blocked for the central islands by Kauai but should see less blockage as the swell swings around to a more northwest direction.

Models indicate there will be a series of small southerly swells throughout the forecast period. Some of these swells will have rather long periods so surf may be inconsistent at times. Do to the lack of trade winds, surf along east facing shores will remain rather small over the next several days, with an uptick expected later in the week and into the weekend as the trade winds strengthen.
