The Lowdown
G’day, it’s Rusty.
To be straight with you, this stretch ahead looks like a tough one. We’ve got a solid-looking fortnight of waves showing on the charts, but the wind gods have got it in for us. That constant east-northeast flow is gonna chop up just about everything, so the real gems are going to be rare. The one window that stands out is the opening afternoon, and even then, it’s a short-lived clean spell before the cross-shore junk moves in.
First up, Tuesday afternoon (September 8th) is your best bet. Windmills (Windmills-1) is looking like the standout of the entire period. We’ve got a 4.3ft swell coming from the ENE with an 11-second period, and it’s pushing a moderate combined energy of 583. That’s a decent, workable wave. But the real story is that light SSE wind, offshore for this spot, with a "clean" call on the water. It’s an advanced reef break, so it's not for everyone, but for those who know their way around, it’s going to be proper. The water temp is a touch warm at 80.1°F, which is pretty much spot-on average for this time of year. Just remember, crowds are a real possibility here, so get out there early.
After that, it’s a long, frustrating slog. From Wednesday morning (September 9th) right through the weekend and into the following week, the east-northeast wind is going to be blowing sideways or cross-off, with speeds picking up from 9 mph to 19 mph and beyond. The swell sticks around, mostly between 2.6ft and 5.2ft, but with periods dropping to 7 or 8 seconds, it’s going to be a jumbled, cross-chop mess with a poor quality call every single time. The energy is all over the place, too, with readings like 102, 185, and 237, just enough to get you out there without giving you anything to ride. It’s a two-week stretch of looking at the ocean and shaking your head.
The second week doesn't offer any favors. The ENE wind hangs in there, and the swell stays up but messy. You’ll see some moderate energy readings in the 300s on the 18th and 19th, with 4.6ft to 4.9ft swells, but the cross-shore wind and short period are just going to keep it lumpy and hard to surf. By the 20th, the storms roll in, and winds get even stronger, making it less about surfing and more about trying not to get blown off your board. The only potential positive late in the window is on the 22nd when we see a cross-off wind state, but the swell looks pretty weak and short-period by then.
Bottom line: if you can sneak out on that Tuesday afternoon, you’re in for a treat. Otherwise, you’re waiting for a serious change in the wind pattern, because this forecast looks pretty grim for paddle surfing. With these strong cross-shore winds and the beach/reef setup, this might be more interesting for the kite crew than anyone else.
So, mark your calendar for the 8th. Don’t sleep on it.

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.
