Forecast for Big Island Windward and Southeast

Forecast for Big Island Leeward

Swell Summary

A small, medium period northwest swell (310 degree) is expected to arrive this afternoon and provide a boost in surf along north and west-facing shores through Monday. This swell will slowly decline late Monday and be gone by Wednesday. A series of smaller northwest to north swells are expected to pass through during the second half of the week. Surf along east-facing shores will experience a minor boost today as trades strengthen over and upstream of the islands. Although trades will slightly weaken over the state early in the week, a persistent moderate trade fetch upstream of the area should result in a continued east shore, short period wind wave chop through the week. Other than very small early to mid week bumps along southwest and southeast exposures from low period energy moving in from the Southern Hemisphere and within the trade belt, respectively, surf along many south-facing shores will remain small.
