The Lowdown
G’day, Rusty here. Well, I’ve gotta be straight with you – the next couple of weeks are lookin’ pretty grim for a paddle. Windmills (reef break) is the only spot on the cards, but the wind is blowin’ from the wrong direction pretty much the whole time, and that ENE breeze is just killin’ any chance of clean waves. The water temp is sittin’ around 81°, which is bang on average for this time of year, nothin’ unusual there.
From today, Sunday the 23rd of August, right through the end of the month, it’s a write-off. We’ve got a solid 6 ft of swell from the ENE on Sunday, but the period is a pathetic 6 seconds and the cross-shore wind is 22 mph – it’s lumpy, choppy, and just plain messy. The combined swell energy is 230 (weak to moderate), but it’s completely wasted. Monday the 24th drops right off to 1 ft from the NW with a long 11-second period, but the energy is only 30 – barely a ripple. Tuesday through to the end of August is more of the same: waist-high to head-high swells from the ENE, short period, and that dreaded cross-shore wind.
That first week is a total gap. There’s just nothing worth paddling out for. The wind never really cleans up, and the swell direction is all wrong for Windmills – it needs a solid NNW to really light up, and we’re gettin’ the complete opposite.
Now, lookin’ into the second week, we finally get a glimmer of hope. On Monday the 7th of September, we see something real promising for the afternoon. A solid 8 ft swell from the NE with a long 12-second period – that’s a true groundswell with heaps of grunt. The combined swell energy hits a massive 1722 (very strong). The wind swings light from the east at just 6 mph, and it’s cross-offshore, which will make the place glassy and clean. That’s the standout of the whole outlook, no question. Just keep in mind that at 8 ft, this is strictly for the experienced crew. It’s also a long-period swell, so at a reef break like Windmills, those sets will be powerful and well-shaped – perfect for a reef. Earlier that same morning on the 7th, there’s a 7 ft NE swell with a 12-second period and a light cross-onshore wind, which is still pretty good but not as clean.
The few days before that, around the 5th and 6th of September, we’ve got big groundswells from the ENE with periods over 13 seconds, but the wind stays cross-shore or cross-on, keepin’ the surface lumpy. The energy is high – over 1000 – but the conditions just aren’t cooperating.
So, the only real window to get excited about is that Monday the 7th of September afternoon. Until then, it’s a long dry spell. If you’re a kite surfer, that constant cross-shore wind and mediocre swell might be your jam, but for a paddle surfer? Wait for that Monday afternoon.
Rusty.

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.
