Forecast for Big Island Leeward

Swell Summary

Update: Added two feet to north facing shores of Kauai and Oahu today.

The current west-northwest swell is holding 2 to 3 feet above forecast guidance at the Hanalei buoy this morning. The delayed arrival of this swell by roughly 6 to 12 hours will also delay the departure. Therefore, the High Surf Advisory (HSA) for exposed north and west facing shorelines was extended in time until this evening. This swell energy will slowly decrease in height over the next 24 hours, likely falling below advisory thresholds by early Monday morning. The next west-northwest swell will move into the region early Tuesday, building surf heights along north and west facing shores back up to HSA levels by Tuesday night. This swell energy will peak on Wednesday night and then fall below HSA thresholds on Thursday. Long range guidance continues to show a much larger west-northwest swell arriving by Friday night, easily reaching HSA levels and potentially exceeding High Surf Warning thresholds by Saturday if the current wave model trends hold. Stay tuned.
