The Lowdown
Alright, folks, Rusty here. Let’s get straight into it. The next 16 days are looking pretty flat for the most part, so we’ve got a long gap before anything really starts to happen.
For the first week and a half, from Monday 3rd August right through to around Tuesday 11th August, don’t bother waxing up. Surf is tiny, mostly 0.7ft to 1ft, with very weak wave energy (16 to 123). The wind is light offshore or cross-off most of the time, which is a shame because there’s just no power behind it. The water temp is sitting at 80°, which is about average for this time of year.
Now, things start to get a little more interesting by Wednesday 12th August. The swell from the SSW picks up to 2ft with a period of 18 seconds (that’s a long period groundswell), and the energy jumps to 255 (moderate). The wind is cross-off from the ENE at 6 mph, so it’s clean but not glassy. This is still pretty small, but it’s the first sign of life.
The real standout, and the only window I’d get excited about, is on Tuesday 18th August. Lahaina Breakwall/Harbour sees a 3ft swell from the west, with a 13-second period and strong energy (328). The wind is offshore from the NE at 12 mph, giving us moderate offshore and clean conditions. This is the best of the whole run—small but clean, and the swell direction matches what this spot likes (WSW optimum). It’s a consistent reef break, so expect a few waves, but just know that crowds are possible here, especially when it’s the only game in town.
Before that, from the 13th to the 17th, we’ve got some 2ft to 2ft swells, but the wind is mostly cross-off and the energy is moderate. It’s surfable but very ordinary, definitely not worth rushing out for.
The bottom line: if you’re keen, aim for Tuesday 18th August. The rest of the 16 days? A long, quiet stretch for Lahaina.
Rusty.
