Lahaina Breakwall/Harbour Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks.

First up, we’re looking at a pretty flat and ordinary stretch of surf for the next week or so. The main break on the cards is Lahaina Breakwall/Harbour, and it’s a consistent reef setup that’s fairly exposed to the swell, with an optimum direction from the WSW. The water temperature is running about average for this time of year, so nothing unusual there.

From Saturday the 29th of August right through until Thursday the 10th of September, it’s a real grind. The swell is tiny, mostly 1 ft to 2 ft, coming from the SW or SSW with a long period of 14 to 18 seconds. The combined wave energy is weak, ranging from 28 to 243 (most days sitting under 100 to low 100s), so there’s just not much push. The wind is offshore or glassy for a lot of those mornings, which is a positive, but with such small swell, it’s still very ordinary. The mornings are the better call, with clean conditions and a gentle to moderate offshore breeze. The afternoons can drop off or get a bit cross-off or messy. Honestly, this is a stretch where you’re better off waiting.

Then, from Friday the 11th of September, things start to get interesting. The swell picks up to 3 ft from the WNW, with a long period of 16 to 21 seconds, and the combined energy jumps to 323 to 569 – that’s moderate energy, and it’s the first time we’re seeing “expect good surf conditions” in the notes. The wind is light offshore or glassy, so the waves will be clean. This is the standout window. The best of it looks like Friday morning, the 11th, with a 3 ft WNW swell, period of 21 seconds, and glassy conditions – that’s a very long period groundswell, so it’ll have plenty of shape and energy, but it might break a bit straight at a beach break; at a reef like Lahaina Breakwall, it should be really good. Saturday the 12th and Sunday morning the 13th also hold clean 3 ft to 3 ft WNW swell with light offshore winds, and the energy is still solid. That’s the window to pencil in, but it’s over a week away, so the long-range forecast is promising but not locked in yet.

Overall, the first week is a dud. There’s a big gap of no real surf until the 11th, so don’t get your hopes up until then. The 11th through the 13th of September is the only real highlight – clean, moderate swell, good period, and offshore winds. That’s your best bet.

Rusty.
