Swell Summary
A couple of late week into early next week small, short to medium period north northwest swells will come through beginning tonight into Friday, as well as Sunday into Monday, that will maintain low end north and west facing shore surf. A small, long period west northwest swell being generated by Northwest Pacific Typhoon Mindulle may reach the islands by Tuesday of next week.
A very small, medium to long period south southwest swell will arrive by tonight and peak Friday. This swell will keep south surf from going completely flat during the remainder of the week.
Choppy wind wave surf along most eastern exposures will remain small the next couple of days. A more late week persistent, stronger trade fetch upstream of the islands may increase weekend east facing shore surf.
