Forecast for Big Island Windward and Southeast

Forecast for Big Island Leeward

Swell Summary

Surf along north-facing shores will see a slight increase through the day as a small, medium period north northwest (340 degree) reinforcement fills in. Areas better exposed to trade swell will also experience an increase in surf heights. North-facing shore surf will then slowly decline from tonight through Thursday. Another small, medium period northwest swell may arrive around Thursday and persist into the weekend to help revive north shore surf heights. Regardless, these series of small impulses will not provide much change to below seasonal average north surf. Small, medium to longer period background south swell, with the occasional medium period south southwest impulse, will hold small surf along south-facing shores through the week. Surf along east-facing shores will remain up the next couple of days in direct response to the fresh to strong winds. Elevated, rough and choppy east surf conditions will peak today before subtly easing into mid week in response to weakening winds. East-facing shore surf should remain under High Surf Advisory criteria through tonight.
