The Lowdown
Alright, let's talk about what’s happening on the West Maui coast. I’ve got to be honest with you, it’s looking pretty small for the next 16 days. The swell is sitting at 1ft to 2ft. Not the kind of thing that’ll have you calling in sick to work, but if you’ve got a log and you just want a saltwater fix, there might be a moment. The water’s at 81°, which is about normal for this time of year.
Starting off on Monday 24 August afternoon, there’s a tiny 1ft SSW groundswell moving in with a 13-second period, so there’s a bit of push behind it, but not enough to do much with. The combined swell energy is weak at 129. The wind is a light offshore from the NNE at 6 mph, so the surface will be glassy clean, but you’ll be floating around waiting for something to stand up on.
Tuesday the 25th and Wednesday the 26th look the same. The swell bumps up to 2ft on Thursday the 27th afternoon, with a 16-second period from the south, and the energy hits 155. That’s the peak of the whole run. The wind stays offshore from the NE through most of this, keeping the surface tidy, but with those tiny heights, you’re going to be scratching for any kind of ride.
The best of a very quiet 16 days is probably Thursday morning, 3 September. It’s still only 1ft, but the wind is a light ENE offshore at 12 mph, and the swell direction from the SSW is right on the money for this break. The period is 14 seconds, so the waves will have a decent shape. The energy is weak at 69, so it’s not going to be pumping, but it’ll be the cleanest little wave you’ll see in the whole forecast period if you just want to glide around.
After that, it goes bad. On the 4th of September, the wind picks up to 40 mph from the NE with thunderstorms and heavy rain. That’s unsurfable. The ocean will be a mess, and that gale-force offshore wind will make paddling out impossible.
The last few days into early September stay tiny. The 7th of September morning has 1ft SSW swell, energy at 140, light ENE wind, so clean, but again, very ordinary.
Look, for the entire 16-day window, the standout isn’t a classic, it’s just the best of a flat spell: Thursday morning, 27 August. The swell combines a 2ft south swell at 16 seconds, the energy is 155, and the wind is a gentle offshore from the NE at 9 mph. It will be clean, the lines will have some length, but you will be waiting for sets. This break is a reef setup, so that long-period groundswell will shape up with some nice walls. Crowds are listed as “sometimes,” so on a Thursday you might find a wave to yourself. The water temperature is normal for the season, so it’ll be a warm, lazy session. Honestly, for most of us, it’s not worth the hassle.
