A very large northwest swell (310-320 degrees) will build through the day today, peak tonight, then slowly decline Thursday and Friday. Surf will exceed High Surf Warning levels along most north and west facing shores, including leeward Big Island, by this evening. In addition, the combination of large wind waves from the west and a mix of medium and longer period swell energy could lead to overwash of some coastal infrastructure and beach erosion, mainly this evening through Thursday morning along exposed north and west facing shores. The swell will decline and shift out of the north- northwest Friday through the weekend.
Minimal trade wind swell is expected this week, though there is some potential for localized wave wrap along east facing shores exposed to the large northwest swell late today into Friday. Rough surf may briefly increase along south facing shores as the front moves down the island chain through today.
