The Lowdown
Alright crew, Rusty here. Let's break down the long-range for Windmills. Gotta be honest, this forecast is a tough one to sell. Over the next 16 days, we've got a whole lot of nothing good for the first week and a half.
Right now, through the end of August and into the first week of September, it's a complete mess. We've got a solid 15 to 22 mph cross-shore wind from the ENE, just tearing the surface apart. There's some swell in the water, in the 4 to 6 ft range, but with those winds, it's all bumpy, lumpy, and cross-chop. That's not surf, that's a workout. You can expect that kind of low-quality slop from now until about the 10th of September. The water temp at the start is about 80 degrees, which is just normal for the season, so the wind chill will be the only thing you feel.
But, there is a light at the end of this ugly tunnel. On the 11th of September, things finally look up. Friday morning we get a light E breeze at just 6 mph, turning offshore from the S by the afternoon. That is the key. We'll get clean waves in the 6 ft range from the ENE. It's not a long-period groundswell, only 8 seconds, so it's a bit windswellish, but with that offshore wind smoothing it all out, it’ll be the cleanest and most fun we'll see all forecast. That's your one shot. This is a standout, but we're talking a week and a half away, so keep your expectations in check until we get closer. After that, the 12th and 13th drop off into tiny 2 to 3 ft weak mush.
This break, Windmills, is an advanced reef. When it gets over 8 ft, it's expert country. We do see some bigger energy around the 8th and 9th of September (over 6 ft with strong energy readings), but the wind is still blowing a messy cross-shore, making it a dangerous, blown-out mess.
In short, we have a long dry spell and one decent window. Lock in the 11th of September as your best bet.
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.
