Forecast for Big Island Windward and Southeast

Forecast for Big Island Leeward

Swell Summary

A pulse of south-southwest swell is producing surf near June average before slowly declining tonight. A series of overlapping pulses of small, long- period south and south- southwest (170-220 degrees) swells will produce mainly background level surf along southern shores Friday through the middle of next week. Choppy, moderate surf will persist along east facing shores due to the trade winds locally, and upstream of the islands. An out-of- season, 3 to 5 foot medium period northwest swell generated by former Northwest Pacific Typhoon Guchol, which has transitioned into an extratropical storm is forecast to arrive this weekend. This swell will provide a boost to north and west shore surf well above June normal peaking Sunday and Monday, before declining Tuesday.
