Forecast for Big Island Windward and Southeast

Forecast for Big Island Leeward

Swell Summary

A small north-northwest swell will build today, peak tonight and Saturday, then lower Sunday into early next week. A slightly larger north swell with a shorter period will arrive late today and tonight then peak over the weekend. A moderate size longer period north-northeast swell should arrive late Sunday or Sunday night. This swell may peak at low end advisory levels along north facing shores Monday, then slowly decline through late next week. Another small medium period northwest swell appears to move through the islands Monday through the middle of next week as well.

Surf will remain small along south facing shores over the next few days with mainly background energy from the south and southeast. Another small, more noticeable long-period south swell is expected to fill in Sunday into Monday with a slow and gradual decline through late next week.

East facing shores will remain small and well below normal during the next 7 days due to a lack of strong trade winds over and upstream of the islands.
