Lahaina Breakwall/Harbour Surf Forecast and Surf Report

Alright, Rusty here again. Let’s break it down for you in feet. For the next 16 days at Lahaina Breakwall/Harbour (Maui), it’s a story of persistent but small swell. The guiding wind is mostly offshore from the NE, which is a bonus for a reef setup, but wave heights are tiny. The wave energy is weak, with combined energy values in the low hundreds, so we’re in “gentle puff” territory. No big swell event in sight.

We start on Thursday, 13 August. Morning brings a 2ft south swell, with a period of 16 seconds – that’s a true long-period groundswell, which wraps in nicely over the reef for shape, but the size is small. Wind is a moderate NE offshore at 12 mph, keeping it clean. Combined energy is 240. The afternoon keeps the 2ft, with wind picking up to 16 mph. It’s surfable but very ordinary.

Friday, 14 August, brings similar. Swell holds at 2ft in the morning, dropping to 2ft in the afternoon. Offshore wind holds at 12 mph. Morning combined energy is 161, dropping to 123. Clean, rideable, but small.

Saturday, 15 August, starts with 2ft in the morning (13-second period) and cleaner ENE wind, but by the afternoon, a cross-offshore from the east at 19 mph messes things up, giving “poor surf conditions.” Combined energy is 106.

Sunday, 16 August, is a wash. Swell drops to 1ft, messy cross-off wind, and a risk of thunderstorms by afternoon. Combined energy falls to 98. Hard pass.

Monday, 17 August, shows a tiny hope. 1ft from the SSW with a 14-second period, and a gentle offshore breeze from the ENE at 9 mph. Combined energy is 92. Clean but weak. The same in the afternoon.

From Tuesday, 18 August, onward, we flatline. Swell holds at 1ft to 1ft, mostly from the SW or SSW, with periods from 13 to 18 seconds. Winds are light to moderate offshore. Combined energy stays in the double digits or low triple digits (66 – 180). Waves are surfable, but you have to want it. There’s no standout day.

The best flicker is Wednesday, 26 August, with combined energy of 180 from a 1ft, 18-second SW swell. The period gives it a bit of push for the reef. Wind is a gentle offshore from the ENE. That’s your best bet, and it’s still only “decent.”

For beginners, this is perfect: waves under 3ft, clean conditions, and a consistent reef. For anyone else, it’s a waiting game. No standouts – just a stretch of consistent but unexciting surf. Long flat spell, but with consistent offshore winds, it’ll at least look pretty. If this were a beach, I’d say get the kite out, but for a reef, it’s a gentle paddle.

Best on offer? The morning of Thursday, 13 August, and Wednesday, 26 August. Keep your expectations small.

This is Rusty, signing off.
