The Lowdown
Alright, Rusty here. Let’s talk about what’s happening with this spot.
It’s a pretty grim run ahead for Windmills. This is an advanced reef break, and it’s fairly consistent, but the problem is the wind. For the entire outlook period we’re looking at a persistent ENE breeze that’s going to mess things up. For the first week, that wind is strong – 15 to 22 mph – and coming straight cross-shore, smashing up any chance of clean waves. The swell is there, coming from the ENE with heights around 4 ft to 6 ft, but it’s mostly short-period junk. The combined swell energy builds from a weak 97 up to a moderate 164 and then into the strong range around 522, but it doesn’t matter because the wind is ruining it. The wave comment says “poor surf conditions” across the board. No standouts, no days worth paddling out here for the first nine days.
It’s not until Friday the 25th of September that we get a tiny glimmer. The wind eases off, swinging SE at 9 mph and turning cross-offshore in the morning. The swell drops a bit to 6 ft from the ENE, still short period of 6 seconds, but the wave comment changes to “marginal” (a rating of 1). The clean conditions make this the one small window. Even then, it’s just a marginal call – not a standout, just the least bad option in a bad run. The break is fairly exposed to the swell, and with its optimum direction being NNW, we aren’t getting the good stuff. After that, Saturday the 27th through to Wednesday the 1st of October goes right back to poor conditions with that strong cross-shore wind back.
Overall, this is a tough 16 days. For an advanced reef, the long period groundswells that would make it shine are missing, and the wind is a constant enemy. There are no good surf options here in this window.
Water temperature is about average for the time of year here at Windmills.

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.
