Forecast for Big Island Leeward

Swell Summary

A combo of a moderate to large medium period NNE swell and a small, medium period NW swell will produce moderate to large surf along north facing shores. N swell gradually fills in this evening, peaking tonight and Monday before gradually declining through the middle of the week. Surf may approach or briefly touch the High Surf Advisory (HSA) threshold during its peak for N facing shores. Another small to moderate NW swell is also expected to fill Monday, and peak Tuesday before declining through the end of next week. Surf along east facing shores will remain small except for shorelines exposed to the north- northeast swell through the first half of the week. Surf along south facing shores will remain tiny through the forecast period with mainly background energy.
