Swell Summary
Surf along north facing shores will trend up next Tuesday through midweek as a long-period northwest swell arrives. This will peak Tuesday night into Wednesday, then ease through the second half of next week. Surf along east facing shores will remain small and choppy into Saturday, then decrease Sunday into next week as the trades weaken. Surf along south facing shores will remain small through the weekend, with mainly a mix of background long-period southwest and short-period southeast swells moving through. An upward trend is possible next Tuesday through midweek due to a slightly larger southwest swell arriving.
