The Lowdown
Alright, Rusty here. Let's talk about what's on the menu for the next couple of weeks.
To be honest, the outlook is a mixed bag. We're looking at a stretch of days where the wind just won't play nice, and the swell direction is fighting us. The water is sitting at a pretty standard 80°F, which is exactly what you'd expect for this time of year, so no surprises there.
The first real chance to get wet is on Tuesday, September 8th at Windmills (reef). The morning will see a clean 5ft swell from the ENE with a moderate period of 11 seconds, and the wind will be blowing offshore from the south at 15 mph. That's a solid start. The combined energy is moderate (517), so there's some push. It's a bit of a wait for the good stuff, but it's worth it. The afternoon is where it gets interesting. The wind swings around to the SSE at a light 9 mph, still offshore, with the swell dropping slightly to 5ft but shifting to the WSW. The period drops to 9 seconds, but the energy jumps up to 756. This is your standout window. The waves will be clean, the wind will be light, and it's a reef break, so expect some proper shape. This is an advanced spot and it's fairly consistent, and it's often crowded, so expect company.
After that, the rest of the week and into the next is a bit of a write-off. From Wednesday, September 9th all the way through to Saturday, September 19th, the wind is consistently cross or cross-off from the ENE, and the swell is mostly short-period and weak. The energy values are almost all under 300, and many are in the low double digits. It's a long stretch of poor surf conditions. There's a small window on Sunday, September 20th in the afternoon where the swell picks up to 4ft from the ENE and the energy hits 219, but the wind is light and cross-off, making it just surfable but very ordinary. Nothing to get excited about.
The absolute best of the entire forecast is that Tuesday afternoon, September 8th session. The light offshore wind, the clean 5ft WSW swell, and the moderate energy make it a clear standout. Head out then, because the rest of the run is a waiting game until the very end of the forecast.
The final day, Monday, September 21st afternoon, shows a tiny 3ft ENE swell with glassy conditions. The period is 8 seconds, so it's a short-period bump, but the energy is moderate (238). It's a potential dawn patrol or late session if you're desperate, but it's not the same quality as the 8th.
Rusty out.

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.
