Forecast for Big Island Leeward

Swell Summary

Sunday's small west northwest swell will diminish through the day. A larger moderate size, long to medium period west northwest swell will build in from Tuesday through Thursday. During this time period a strong, slow-moving Bering Sea low will send a moderate size, long to medium period north swell into the local waters. This mixed west northwest and north swell will have resultant mid week surf heights along many exposed north and west facing shores likely achieving High Surf Advisory (HSA) heights by Thursday. An extended west fetch will develop far northwest of the islands later this week and push a third, even larger northwest swell into the island waters this weekend. If this swell does materialize, there is a good probability of it generating XL-size, warning level surf along north and west shores next weekend.
