Lahaina Breakwall/Harbour Surf Forecast and Surf Report

G’day, Rusty here. Look, I’ll level with you – this 16-day window isn’t going to set the world on fire. We’ve got a long stretch of tiny, weak surf. Offshore winds are a regular feature, keeping things clean, but the size just isn’t there to get pumped about. It’s a flat spell, plain and simple, but with these consistent breezes, if anything sneaks in, it’ll be tidy.

We start Friday, August 28th, with the only game in town being Lahaina Breakwall/Harbour. We’re talking knee-high waves at best – 1 ft from the SSW with a period of 14 seconds. There’s a bit of long-period groundswell energy, but the combined energy is weak (84). The wind is blowing offshore from the NE, light to moderate, so it’s clean – glassy in the morning. You might snag a workable little wave if you’re on a longboard or a foil, but it’s more of a paddle than a proper surf.

Saturday the 29th is the same – 1 ft, poor conditions in the morning and just ordinary in the arvo. We drift through Sunday, Monday, and into the start of September with the same story: tiny 1 ft to 1 ft SSW swells. The winds stay offshore or cross-offshore, keeping the surface clean, but the wave energy is mostly below 100. Tuesday afternoon (Sept 1st) goes cross-off and the score drops – still no dice.

Wednesday, September 2nd, gives us a tiny bump – 2 ft from the SSW with a period of 16 seconds and a combined energy of 155. It’s still small and mediocre, but that’s the high point of the first week. The water temp is about average for the time of year.

Then we hit a dead zone. From Thursday the 3rd of September through to Saturday the 5th, the forecast turns to poor surf conditions with energy dropping into the 30s and 40s – a complete gap. Sunday the 6th brings a return to 1 ft to 2 ft SW swell, with energy climbing back above 100, but it’s still just ordinary.

Things finally show a little life on Monday, September 7th. We get a 2 ft SSW swell at 16 seconds – nice long period. The combined energy hits 215 and then 257 in the arvo. The wind is offshore from the NNE, giving us clean, lined-up conditions. For Lahaina Breakwall, this is the standout moment across the whole outlook. The waves are still waist-high, but the quality is the best we’ll see.

Tuesday the 8th holds similar 2 ft SSW swell with strong energy (216 in the morning, 201 in the arvo) and offshore winds – clean and rideable. After that, it fades again. Wednesday the 9th and Thursday the 10th drop back to 1 ft to 2 ft, with energy dropping. Friday the 11th we get a glassy morning (1 ft from the SSW) but it’s tiny. Saturday the 12th sees a bit more life with 1 ft SW swell at 16 seconds and energy of 109, but we’re out of runway.

So, the best of the whole 16 days is Monday the 7th and Tuesday the 8th of September – that’s your only real window where the swell and wind line up. Even then, it’s not a big-wave day, but for a clean, offshore wave on a reef break, those are the sessions. Crowds are listed as “sometimes,” so you might have a few other heads out, but nothing crazy. For beginners, the 2 ft is perfect – not too big. For experts, it won’t even get your heart rate up.

Other than that, it’s a long, quiet stretch. Keep your board handy, because this area tends not to stay flat for long, and forecasts can change.

Rusty.
