The Lowdown
Alright folks, Rusty here. Let’s have a look at the local scene for the next couple of weeks. Honestly, it’s a bit of a tough stretch ahead. We’re starting with a long gap of nothing worthwhile, and most of the window is plagued by strong, cross-shore winds that are going to make things messy. The water temp is sitting at 80°, which is bang on average for this time of year, so at least you won’t need a thick suit.
The first session that’s even worth a mention won’t arrive until Saturday the 5th. Before that, forget it – Tuesday through Friday is all rain showers, clear skies, and a fresh breeze that’s either cross or cross-off but never really offshore. The swell is there, but the wind is just too strong and lumpy.
Now, Saturday the 5th and Sunday the 6th are the only real standouts in this whole outlook, and even then, they’re marginal. The best bet is Windmills, a reef break for advanced surfers only. On Saturday morning, we’ve got a solid 6 ft swell from the ENE, but here’s the thing – that period jumps to 13 seconds, which is proper groundswell. The combined energy is massive at 1019 (moderate to strong), and the wind is a moderate cross-shore. The afternoon holds similar at 6 ft with even more energy (1174). It’s not perfect, but it’s the best we’re going to get. Keep in mind this spot is fairly exposed and the optimum swell direction is NNW, so the ENE swell isn’t hitting it dead-on. It’s a marginal call, but with a bit of luck, there’ll be some clean, longer-period lines rolling through. Crowds are likely here, so get in early.
Sunday the 6th is a carbon copy – 6 ft ENE swell, 12-second period, and that same moderate cross-shore breeze. The energy is still high at 985. Again, not glassy, but the quality of the swell energy is decent. Windmills is your only real play for the entire forecast.
After that, it drops off hard. Monday the 7th shows a slight improvement in wind with a gentle cross-off breeze and 5 ft swell, but it’s still just a marginal call. Then from Tuesday the 8th onwards, it’s a long, poor run. The wind stays cross or cross-off but fresh, and the swell direction gets weird, swinging to the WSW and then to the NNE. By the second week, the swell drops to below 3 ft and the energy dries up to nothing. A couple of days around the 12th of September show a massive 13 ft pulse from the ENE, but with a strong cross-wind and a period of just 9 seconds, that’s heavy, short-period junk – really only for the hardcore chargers, and honestly, it looks more like a kite-surfing setup than a paddle session.
Bottom line: the only two days worth circling are Saturday the 5th and Sunday the 6th at Windmills. It’s not a classic, but it’s all we’ve got. After that, you’re better off waiting for the next forecast run.

Information about the Windmills Surf forecast
The above surf forecast table for Windmills provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Windmills can be found by selecting the local surf guide option on the grey menu. Our Windmills surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Windmills) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Windmills may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Windmills is 20 km (12 miles) from Wailuku. If you plan a vacation in Maui, look for hotels and other accommodation in Wailuku. Wailuku has rooms for a wide range of budgets as well as car hire and transport links.
