The Lowdown

Alright, this is Rusty, your local surf reporter. Let me tell you about what's on the menu for the next couple of weeks at the Lahaina Breakwall/Harbour.

Alright, listen up. The outlook for the Breakwall over the next 16 days is pretty flat, to be honest. There’s not a whole lot of energy coming in, and what is here is hardly gonna get you out of bed. We're looking at a long stretch of very small, ordinary surf.

The best of a quiet period is shaping up for Wednesday the 18th of September. We've got a clean 2ft of swell coming from the SW, and the wind is offshore from the ENE at 9 mph. That combo is about as good as it gets in this forecast. The wave energy will be moderate, sitting around 283 (moderate wave energy). It’s a reef break that's fairly exposed, and with this consistent south-west swell direction matching what it likes, it'll be a workable wave for the crew who are happy to ride a longboard. The water temp is a warm 80°, which is bang on average for the time of year. Keep in mind, crowds are possible here, so you might have some company.

Rightio, let’s run through it.

The period kicks off with a very small window. Wednesday the 9th of September has some rain showers and a tiny 3ft swell from the NW, but the 6 mph E wind is cross-offshore, making conditions ordinary. The energy is weak (141). Thursday the 10th looks similar with a tiny 1ft SW swell but the wind goes offshore from the ENE and NE. It’s clean, but there’s just no power behind it. This very ordinary pattern of small, clean waves with minimal energy continues right through the weekend and into the start of the following week.

We hit a bit of a lull from Sunday the 13th into Monday the 14th where the swell drops to just 1ft and the conditions are described as poor. There is a small spike on Monday afternoon with a longer period swell of 22 seconds from the SW, giving a moderate 106 energy, but the 1ft height is still tiny.

Then we see the best window of the outlook. Tuesday the 15th starts with a glassy 2ft SSW swell. It’s super clean with no wind. Then Wednesday the 16th and Thursday the 17th show building energy with offshore winds and moderate combined swell energy (283 and 232 respectively). The waves are still only 2ft, but the quality will be noticeably better than the rest of the run.

Friday the 18th is the pick of the bunch as I mentioned - 2ft, clean, offshore, with moderate wave energy (283). It’s the most likely day you'll get a few fun little runners.

After that, the energy starts to fade again. Saturday the 19th and Sunday the 20th offer small, clean waves, but the energy drops off significantly. By Monday the 21st and Tuesday the 22nd, we’re back to tiny, poor conditions. There’s a slight bump in energy on Wednesday the 23rd and Thursday the 24th, but the wind turns messy, going cross-shore, and the surf quality is marginal.

The honest truth is, the Breakwall isn't firing. If you're a local, you know the drill. The whole period is pretty flat, so don't get your hopes up for anything with any punch. The entire 16-day run is a quiet one for the area.

Rusty.
