Swell Summary
A new long-period northwest swell will build tonight, peak Sunday into Sunday night, then lower on Monday. This swell will give a slight boost to surf along north and west facing shores, but will likely remain below advisory levels. The next in the train of northwest swells will arrive late Sunday night, peak Monday through Tuesday, then gradually decline through Thursday. This swell may bring another round of advisory level surf to most north and west facing shores Monday afternoon through Tuesday night. A much larger long-period northwest swell could bring warning level surf to most north and west facing shores next Friday.
East shore surf not exposed to the series of northwest swells will gradually rise today as the trades return over and upstream of the islands. Surf along east facing shores will then hold relatively steady Sunday, then lower a bit Monday and Tuesday as the trades ease. East shore surf looks to become very small Wednesday and Thursday as the trades become disrupted, with a north swell potentially giving surf a boost next Friday.
South shore surf will remain very small through the middle of next week. An out of season long-period south swell may move through the islands late next week, bringing a sizable boost to south shore surf.
