With Tropical Storm Lala now well west of the islands, fresh to locally strong easterly trade winds have filled in across the entire coastal waters. A Small Craft Advisory (SCA) remains in effect for the windier waters and channels around Maui County and the Big Island through tonight, but trade winds will gradually ease dropping into the moderate to locally fresh range by Tuesday. During the second half of the week, trades will weaken further to become light and variable for most waters before strengthening again this weekend.
Surf along south facing shores remains elevated from a moderate, medium to long period swell that has peaked and plateaued this evening. Observations at PacIOOS buoy Barber's Point shows the south swell maintaining at roughly 4 feet, 14 seconds through tonight. However, it is still expected to slowly decline through midweek, so the overall trend remains unchanged. Some wrap also continues this evening for west facing shores, but this is also expected to follow suit as the south swell declines. Another long period south swell generated from gales just south and east of New Zealand will begin arriving late this week.
Surf along east facing shores will continue to fade tonight as Lala moves further west away from the state and as trades decrease on Tuesday. North facing shores will remain tiny throughout the week.
Small Craft Advisory until 6 AM HST Tuesday for Alenuihaha Channel-Big Island Leeward Waters-Big Island Southeast Waters- Maalaea Bay-Pailolo Channel.
