Forecast for Big Island Windward and Southeast

HIGH SURF ADVISORY FOR EAST FACING SHORES

Forecast for Big Island Leeward

Swell Summary

Surf heights along east facing shorelines will remain solidly within High Surf Advisory (HSA) criteria through Wednesday, driven primarily by a large and persistent fetch of fresh to strong trade winds upstream of the islands. The HSA in effect through Tuesday night, though an extension through Wednesday is looking likely as strong upstream trades are expected to persist.

Surf will remain small along north, west and south facing shores through Saturday, as no significant swell-producing systems are evident in the medium range forecast.

In the extended range forecast, forerunners from the next moderate to large, long period north (010-020 degree) swell appear to arrive by late Sunday night, building swiftly to advisory levels through next week Monday, and then slowly declining into the middle of next week.
