Forecast for Big Island Leeward

Swell Summary

South-facing shore surf will remain low through the week with the continued passage of small, long period background south southwest swell. A swell originating from a gale moving east of New Zealand early next week will be directed within the island's south southwest swell window and is timed to reach our local waters next weekend. This slightly larger, medium to long period swell will support a noticeable increase in south shore surf. A series of small, medium period north swells from a couple of systems northwest of the state, between the western Aleutians and the International Date Line, will produce minor bumps to late week north-facing shore surf. East wind wave chop will remain slightly elevated under generally moderate to fresh east trade winds over and upstream of the islands.
