The Lowdown
G'day, I'm Rusty.
Let's be straight up – Windmills is a reef break that only the advanced crew should be looking at, and even then, this 16-day outlook is a tough one. The water temp is sitting at 80°, which is pretty much what you'd expect for this time of year, nothing unusual there.
The first week is a write-off. From Saturday the 25th through to Tuesday the 29th, we've got cross-shore winds and chop making a mess of things. The swell is there, coming in from the NE at 4ft to 7ft, but with a short, weak period of 7 to 8 seconds, the energy is pitiful (combined energy around 134 to 392). It's just messy.
Then we get a window. Wednesday morning the 29th – that's the standout. A clean SSE offshore breeze of only 10 km/h blows into a 7ft NE groundswell with a 10-second period. The combined energy jumps to 922, which is decent, and the offshore wind means it'll be glassy. This is the one to point your board at. But keep in mind, this is an advanced reef break and crowds are often an issue here. That 7ft is manageable for the experienced, but beginners should sit this one out.
Wednesday afternoon holds some clean lines too, but the swell drops to 4ft from the ENE.
After that, it's back to grim. From Thursday the 30th right through to Sunday the 9th of August, it's a solid run of poor conditions. Wind stays on it from the ENE, mostly 15 to 25 mph, creating lumpy, choppy, cross-shore slop. The swell bounces around from 4ft to 7ft, but the period is all over the place – 6 to 11 seconds – giving weak, short-period energy (combined energy between 144 and 529). Even when the wave comment says "clean" on a few afternoons, the wind is still fresh and cross-off, so it's not going to be worth the paddle.
Honestly, for the 16-day run, you've got one real shot: Wednesday morning the 29th. After that, it's a long dry spell. The consistent onshore wind just won't let up. For a reef break with this much cross-shore wind, it's more interesting for a kite surfer than a paddle surfer most days.
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.
