The Lowdown
Alright folks, Rusty here. Let's break down what's coming our way for the next couple of weeks.
We're looking at a long stretch of small, clean surf ahead. The good news is we've got consistent offshore winds, but the real story is the wave height. For the first week and a half, it's going to be very small, nothing that's going to get the heart pumping. You'll be scratching for anything rideable. Things start to show a bit of life around the 7th of September, but even then, it's not a blockbuster. The best window looks to be from Monday the 7th into Tuesday the 8th.
Let's get into the specifics for Lahaina Breakwall/Harbour. The water temperature is sitting around 81°, which is pretty much bang on what you'd expect for this time of year, so no wetsuit needed.
The whole period is dominated by a very small, weak swell. The combined energy is mostly in the double digits, often under 100, which is ultra weak, and only occasionally nudging into the low triple digits, like 140 (Wednesday 26th) or 145 (Wednesday 2nd). The standout period is Monday the 7th of September. The swell ticks up to 2ft from the SSW with a period of 15 seconds, giving a combined energy of 306, which is moderate. That's the biggest pulse we see. The wind is offshore from the ENE, light at 6 mph, so it'll be clean. Tuesday morning the 8th is still okay, with 2ft from the SSW and 14-second period, but the energy drops back to 227.
Because the swell is so small, it's never going to be too big for anyone. The real issue is just finding enough push. The SSW direction is a good match for the optimum at this break. The consistent offshore winds are a major positive, keeping the surface glassy.
The biggest gap of poor conditions is from the 9th of September onwards, where the swell drops back to nothing and the winds freshen up considerably, making it look pretty ordinary.
If you're a beginner, the small conditions from the 7th to the 8th might be alright for a learning session, as the waves are tiny and clean. For everyone else, it's a long wait for a very modest bump. The crowds here are listed as "sometimes", so with the small size, it shouldn't be a zoo.
So, to sum it up: the only real window to get wet is the 7th of September. It's a small, clean, long-period swell from the SSW. It's not going to be pumping, but it's the best we've got in a very quiet period.
Rusty.
