Swell Summary
The current south-southwest swell that has peaked will slowly drop tonight through the rest of the week. A High Surf Advisory is in effect for all south facing shores of the Hawaiian Islands through 6AM.
Along north facing shores, a moderate long-period northwest (310-320 degree) swell has also peaked. However a smaller short- period northwest swell is expected over the weekend into early next week.
As the long-period south swell declines on Thursday, strong to gale force southerly winds are expected to develop and strengthen even further Thursday night into Friday. This increase of southerly winds will bring a rapid increase of short- period energy Thursday into Friday and will once again bring surf heights above the advisory thresholds for south facing shores. Large disorganized surf is expected along many south facing shores Thursday into Friday.
Surf along east facing shores could see an increase later this week due to the strengthening southeasterly winds especially for southeast exposures.
