The Lowdown

G’day, Rusty here. Look, I’ll level with you – the next couple of weeks around Lahaina Breakwall/Harbour aren’t going to have anyone calling in sick for a big swell. It’s a real mixed bag of tiny, clean waves and some proper nasty stuff that’s best watched from the shore. The standout window, if you can call it that, is the middle of the first week. Wednesday the 12th has the best combination of conditions, and then again, the end of the run, Tuesday the 25th, looks like a repeat performance.

Right now, the water is a comfortable 80°, which is pretty much dead average for this time of year – no surprises there.

So, starting off on Monday the 10th, we’ve got a bit of swell at 1 ft from the SSW, with a long 15-second period. The wind is offshore from the ENE at 9 mph, so it’s clean, but the wave energy is only moderate (123). It’s surfable, but very ordinary – more of a longboard or a cruise. Tuesday the 11th is a carbon copy, just with a lighter breeze.

Now here’s the pick of the early run: Wednesday the 12th. Swell bumps up slightly to 2 ft from the SSW, but the period stretches to a very long 18 seconds. That’s proper groundswell energy, and the combined energy jumps to a solid moderate rating (283). The wind is offshore and gentle in the morning, then a moderate breeze in the afternoon. It’s a reef break, so that long period won’t be an issue – it’ll wrap in nicely. Expect good, clean surf. This is the best on offer for the first week. The morning of Thursday the 13th is still okay with gentle offshore wind and 2 ft swell (240 energy), but it’s a step down.

Then things go pear-shaped. From Friday the 14th through to the end of the first week, the conditions deteriorate fast. Friday is still offshore but the swell drops. Saturday the 15th, the wind is howling at 22-25 mph from the NE – that’s a fresh to strong breeze, and while it’s offshore, it’s going to be hard to paddle into and just plain unpleasant. Sunday the 16th gets ugly. A risk of thunderstorms and cross-onshore wind swings from SSE to S, hitting 16 mph. The afternoon shows a sudden spike in swell to 8 ft from the S, but with a short, weak period of only 7 seconds and a massive energy reading of 709. That’s strong wave energy, but the wind is choppy and cross-onshore, making it a complete mess. For a reef break, this will be unsurfable – maybe better for a kite session than a paddle.

After that chaos, Monday the 17th turns dead calm. Glassy conditions with no wind and a tiny 3 ft S swell that’s short-period (6 seconds) and weak energy (108). It’s clean but tiny. From Tuesday the 18th right through to Sunday the 23rd, the pattern settles into a boring rhythm: tiny 1.0 ft to 1 ft SSW/SW swells with decent periods (14-20 seconds) and light offshore or cross-off winds. The wave energy sits in the weak to low-moderate range (79 to 128). Surfable, but you’ll be fighting for a dribble on a longboard. The exception is Thursday the 20th and Friday the 21st mornings, which have a light offshore breeze and clean lines – still tiny, but you could get a few.

Then we hit the final standout. Tuesday the 25th. The swell bumps up to 2 ft from the SSW, with a 16-second period and a combined energy of 293 – that’s moderate wave energy, similar to Wednesday the 12th. The wind is a gentle offshore from the NE at 9 mph. Expect good surf conditions again. Considering the whole forecast, this is the other true standout. The long period means it’ll draw nice lines down the reef, and the offshore breeze will keep it glassy.

So to wrap it up: the first week’s pick is Wednesday the 12th, and the second week’s hope is Tuesday the 25th. Everything else is small, clean, and very ordinary. It’s not a total write-off, but you’ve gotta pick your moment.

Rusty.
