Lahaina Breakwall/Harbour Surf Forecast and Surf Report

Alright, this is Rusty. Let’s talk about what’s happening in the water over the next couple of weeks.

This forecast is a classic case of small, clean waves hanging around for days, but nothing really fires up to get the heart pumping. We’re looking at a long run of knee-to-waist high surf coming from the southwest, with mostly offshore winds keeping things tidy. The best of the best? Honestly, it’s all pretty mellow, but I’ll point out the couple of sessions that stand out from the pack.

The first real action worth paddling out for kicks off on Monday, the 31st of August. Lahaina Breakwall/Harbour is showing clean, gentle surf. The combined energy is weak (87), but you’ve got a 1ft groundswell from the SW with a very long period of 15 seconds, pushed by a gentle offshore breeze. It’s glassy and clean, perfect for a longboard or a funboard. The water temperature is about average for the time of year.

Tuesday, the 1st of September, looks almost identical, but the swell period jumps to 18 seconds, which is super long. The energy bumps up to moderate (124). This long-period groundswell will wrap around nicely, but it might break a little too straight for a beach break, which is fine because the harbour is a reef setup. Still small, at 1ft, with a gentle offshore wind.

The pick of the whole period, if you can call it that, is Wednesday the 2nd of September. The morning session has the biggest swell of the run at 2ft from the SSW, with a 16-second period and a moderate combined energy of 155. The wind is a gentle offshore from the NE, so it’ll be clean and lined up. This is the best chance for a little punch on the incoming tide.

After that, things get smaller and more inconsistent. Thursday the 3rd and Friday the 4th drop off to poor conditions with very weak energy. There’s a slight bump on Saturday the 5th with a 2ft SSW swell, but the period drops to 11 seconds, and the wind goes cross-off. It’s still surfable, but nothing special.

The second week is a real snoozer. From the 7th of September onwards, the swell stays tiny, mostly 1.0ft to 1ft, with the odd pocket of energy. The wind stays favorable—offshore or cross-off—but the waves are just too small to get excited about. There’s a glassy moment on the afternoon of the 9th, but it’s only 1ft. The last day worth mentioning is Sunday the 13th of September, with a 1ft, 16-second SW swell and a light cross-off breeze, but it’s still just a fun-sized wave.

So, the bottom line: if you’re desperate for a paddle, aim for the first three days of the period, especially Wednesday the 2nd. After that, it’s a long, flat run. The forecast can always change, but for now, it’s a waiting game.

Rusty.
