Forecast for Big Island Leeward

Swell Summary

North facing shore surf heights will gradually lower early today but at a slower pace due to an overlapping small, medium period northwest swell filling in behind this past week's diminishing northwest swell. A slightly larger, shorter period north northwest swell will arrive this afternoon, peak tonight and then subside from early Friday into the weekend. A large north swell is timed to reach the island chain Saturday night and peak Sunday. This swell will increase early week north shore surf heights to above High Surf Advisory thresholds, possibly as high as low-end High Surf Warning levels. Advisory level surf will begin to fall Monday but a reinforcement northwest swell Tuesday will maintain advisory to potentially warning level surf along north and west facing shores into the middle of next week.

A few slightly larger, lower period south southeast swells have reached the islands and are providing a minor bump to south shore surf. A couple of late season small, medium period south swells coming in the next few days will hold current south shore surf heights through the weekend.

Surf along directly east facing shores, with the exception of more northern or southern exposures experiencing a higher north or south swell wrap, will exhibit a very small chop through early next week in response to light and variable breezes.
