Swell Summary
A moderate, long period northwest swell (320 degree) will hold before reinforcing north- northwest swell (330 degree) fills in tonight and peaks Thursday morning. These swells will keep surf elevated, therefore a High Surf Advisory for select north and west facing shores remains in effect through Thursday. These overlapping swells will slowly decline Thursday night into the weekend. Another moderate, long period northwest swell (320 degree) should gradually fill in on Sunday and could produce surf near the advisory threshold by Sunday afternoon. A combination of small north swells and small west-northwest swells then look to arrive next week.
East shore surf will remain small through the forecast period due to the absence of trade winds. Expect minimal background surf for south facing shores, with a minor south- southwest pulse expected today into Thursday. South facing shores could receive small to moderate choppy windswell Saturday through next week from the southwest winds. This would depend on the location and strength of the front, likely largest for southwest shores of Kauai.
