Swell Summary
The first in a series of long-period swells will arrive late Tuesday afternoon or evening and will push south shore surf to summertime average on Wednesday. Long-period forerunners of a much larger swell will overlap the first swell on Wednesday, and the new swell will peak at 4 to 5 feet on Thursday, producing surf in excess of the High Surf Advisory threshold through Friday. The swell will gradually decline over the weekend and will be followed by another sizable south swell early next week. Smaller short-period southeast to south swells from nearby tropical systems may also move through the area Wednesday into Friday.
East shore surf will trend up over the next few days as trade winds strengthen. Surf along east facing shores will rise to seasonal average late Wednesday or Thursday and hold into the weekend, followed by a likely 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.
