Swell Summary
The current northwest swell will hold relatively steady today, remaining just below advisory levels along north facing shores. A new much larger long-period northwest swell will begin to fill in later today, then rapidly build to advisory levels along most north and west facing shores of the smaller islands tonight and to warning levels on Tuesday. The swell will peak at extra large levels Tuesday night and Wednesday, before gradually declining through the remainder of the work week and into the upcoming weekend. For the Big Island much of this swell will be blocked by the smaller islands, however, surf will likely rise to advisory levels along west facing shores late tonight through Wednesday night and possibly Thursday. Surf along north facing shores of the Big Island will likely reach advisory levels as well late Tuesday through Thursday and possibly Friday.
Along south facing shores, a series of south-southwest swells will keep surf well above the October average through much of the work week. East shore surf will remain very small during the next 7 days in areas not exposed to any wrap from the northwest or the south.
