Swell Summary
Surf along E and SE shores gradually builds in response to strengthening trades and short period fresh swell emanating from Tropical Storm Moke. The direction of this swell will transition to S and then SW as Moke advances west. A High Surf Advisory (HSA) may be needed for the SE shores of the Big Island tonight into Sunday, but at this time it appears surf will fall shy of the HSA threshold.
Surf along S shores remains slightly below the summer average but still slightly elevated through the weekend due to a small, long period SW swell. A series of long period S swells arrive during the middle of next week bumping surf to around the advisory threshold.
A small medium to long period NW swell originating from Hurricane Lala provides elevated surf along N and W shores this weekend.
