The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cooking for the next couple of weeks. We’ve only got one spot on the menu for this stretch, so we’re keeping it local.

Right now, things are pretty quiet. The surf is small and the conditions are nothing to write home about. We’ve got a bit of a wait before anything worth paddling out for shows up.

The first real glimmer comes in on Sunday afternoon, September 6th at Lahaina Breakwall/Harbour. We’re looking at a 3ft SW swell, with a period of 12 seconds, and winds are blowing offshore from the NE at 9 mph. That offshore wind is a major positive—it’ll keep the waves clean. The combined energy is sitting at a moderate 334. The water temp is around 80°, which is pretty much average for this time of year, nothing weird going on. This is the standout session of the whole outlook. It’s small but clean, and that’s about the best we’re going to get. Expect some company though, as crowds are a factor here sometimes.

After that, things get a bit disappointing. Monday the 7th has some small waves (3ft) but the wind swings cross-off, and the quality drops. By Tuesday the 8th, the swell bumps up to 6ft with a cross-onshore wind, and the conditions turn choppy and poor—not worth your time unless you’re on a kite.

We then hit a long, flat stretch. From Wednesday the 9th right through to Monday the 14th, the swell drops to tiny 1.0-2ft waves. The energy is weak (under 114 most days), and despite some nice offshore winds, there’s just not enough push. That’s about a week of barely surfable slop.

A little pulse shows up around Tuesday the 15th, with a 2ft SW swell, but the period jumps to a very long 20 seconds. Long period like that will be breaking a bit straight at a spot like this, so manage expectations. The energy is moderate (208), but the size is just too small to get excited about. Conditions are still clean. That vibe carries on through the rest of the outlook, with small 1ft to 2ft swells, clean conditions, and winds that are offshore or cross-off. It’s consistent in the sense there’s always something, but it’s never more than ordinary.

For the absolute best of the 16 days, you want Sunday afternoon, September 6th. It’s the only window where size, wind, and period align into something clean and fun. After that, it’s just small and clean but nothing that’s going to get your heart racing.

Stay patient, and keep an eye on the forecasts—it tends not to stay this quiet forever.
