The Lowdown
G’day, Rusty here. Let’s be straight with you—this outlook is a tough one. We’re looking at Windmills, and honestly, for most of the next 16 days, the surf just isn’t happening. There’s a stretch from now all the way until the morning of Monday, 17th August where conditions are poor—that’s nearly a full week of flat, messy, or blown-out waves. Don’t even bother paddling out before that.
Now, Monday morning, 17th August is the first and only real highlight. We get a 7ft swell from ENE, with a 10-second period and moderate offshore wind from the SSE. That wind is your friend here—clean faces, good shape. The combined swell energy clocks in at 869 (moderate), and the break says “expect very good surf conditions.” Windmills is a reef break, advanced only, and it’s fairly consistent with a NNW optimum direction. The swell is angled ENE, which isn’t its favourite, but the offshore wind and clean conditions will make up for it. Crowds are often here, so expect some company. This is your window.
After that, it drops back into poor form from Tuesday 18th August onward—small, weak, and cross-shore winds messing things up again. The water temp is about average for this time of year, nothing wild.
So, mark your calendar for Monday the 17th. It’s your best shot. Everything else is a write-off.

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.
