Swell Summary
The first swell of a multi-day buildup of surf is building across local waters. Forerunners from the next much larger swell will start to fill in tonight, and peak late Thursday at well over advisory levels, potentially warning levels near its peak, and hold through Friday. The swell will gradually decline over the weekend and will be followed by another long period south swell early next week.
East shore surf will trend up over the next few days as strengthening trade winds generate larger wind waves. Surf along east facing shores will rise to seasonal average late this evening or Thursday and hold into the weekend, followed by a possible decline early next week.
Flat summer conditions along north facing shores may be interrupted this weekend by a small long period northwest swell from Typhoon Krosa, currently in the western Pacific.
