Swell Summary
A moderate size, medium period northwest swell peaked earlier today and will gradually decline over the next few days. A pair of gale lows in the North Pacific will send a series of small northwest to north-northwest swells Friday night into the weekend and into the first half of next week. These swells should help maintain near average to slightly below average surf along north facing shores into next week.
A moderate size, medium period north northeast quickly filled in peaked during the day today. This swell has been producing advisory level surf along east facing shores and above average surf for select west facing shores of Maui and the Big Island near Kua Bay. This swell will slowly decline through the remainder of the week. Strengthening trades later this week will support closer to seasonal average surf for eastern exposures this weekend.
Small westerly swells from former Super Typhoon Sinlaku will continue to hold over the next few days and is expected to decline over the weekend. A small southwest swell from the Tasman Sea is expected over the weekend. No significant south swells are expected through the first half of next week.
