The Lowdown

Alright, Rusty here. Let’s be straight with you – the next couple of weeks are looking rough for a proper session. There’s no real standout in this first week, but hang in there, because towards the end of the period, things get interesting, albeit with a big caveat.

We start off with nothing worth paddling out for. From Thursday the 27th of August straight through to Monday the 8th of September, it’s a long, frustrating stretch. The only break on the cards is Windmills, an advanced reef setup. The problem is the wind. It’s hammering out of the ENE all day, every day, sitting at 15-19 mph, locking in a persistent cross-shore chop. The swell is small – around 4ft to 6ft – coming from the ENE with a short, weak period of 5-7 seconds. The combined wave energy is weak to moderate at best (values around 87-400), but with that wind, the surface is just lumpy and messy. The water temperature sits at a warm 80°F and the anomaly of 0.3°F means it’s just about average for this time of year, so at least a wetsuit isn’t a worry. But honestly, this whole first stretch is a write-off for a clean wave.

Now, the real point of interest comes on Monday the 8th of September. The swell starts to pick up. By Tuesday the 9th of September afternoon, we’re looking at a solid 7ft swell from the ENE with a period jumping to 12 seconds – that’s real groundswell energy pouring in. The combined energy rockets up to 1045, which is strong energy. But the wind is still on it, blowing cross-shore at 12 mph, so it’s not glassy. The quality is still low, rated as marginal. A 7ft swell on an advanced reef like Windmills will be a handful, and with the wind messing it up, only the most experienced locals are going to find anything.

The best on offer actually falls on Thursday the 10th of September and Friday the 11th. We see a small drop in wind to just 6 mph from the ENE, still cross-shore but now a light breeze. The swell bumps up to 7ft-8ft from the ENE, with a period of 10 seconds. The combined energy is very strong – 1012 to 1210. This is big, powerful surf. For an advanced reef like Windmills, this is strictly for experts. At over 8ft, it’s not a day for beginners, and the light cross-shore will still put some ripples on the face. It’s the best energy of the whole forecast, but with the direction not being the optimum NNW for this break, and the wind not truly offshore, it’s a powerful but messy prospect. The swell direction is ENE, which isn’t straight into the break’s preferred window, so expect it to be a bit walled up.

Because the wind is always cross-shore and the setup is a reef, even with the big swell this is looking more like a tough paddle than a clean drop. If you’re a confident charger, Thursday the 10th of September morning is the pick of a mediocre bunch. Otherwise, give it a miss.

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.
