Swell Summary
Tiny surf along north-facing shores will grow slightly tonight into Thursday and then remain steady Friday as a small northwest swell arrives. A slightly larger medium-period north-northwest swell will follow this weekend. A potential storm-force low developing north of Japan will likely send a larger long-period west-northwest swell early next week.
Surf along south-facing shores will remain small before a series of small to moderate, south-southwesterly swells boosts surf heights to near to above seasonal average this weekend into early next week.
East-facing shores will see trade-wind swell decline through tonight as trade winds decrease, leading to a slight reduction in surf through the remainder of the week. A small, medium-period east swell forecast to arrive Thursday may help maintain east- facing surf into the weekend.
