Forecast for Big Island Windward and Southeast

Forecast for Big Island Leeward

Swell Summary

The current northwest swell will continue to slowly lower into this evening, with surf heights well below High Surf Advisory (HSA) levels. A large long- period northwest (310-320) swell will impact the local waters during the first part of this week. Long- period forerunners are expected to arrive tonight, followed by building swell through Monday night. Surf will rise to HSA heights by Monday afternoon for north and west facing shores and perhaps approach warning criteria as it peaks Monday night through Tuesday. The swell will slowly subside Tuesday night through the end of the week.

Moderate southeast flow will maintain small chop along east facing shores, while background energy out of the southerly quadrant keeps small surf in place for south facing shores.
