The Lowdown
Alright, this is Rusty. Let's have a look at what's on the cards for Windmills over the next couple of weeks.
Honestly, I gotta be straight with you – it's a pretty grim stretch ahead. We're looking at a solid run of days where the surf just isn't happening. The wind is a persistent problem, hammering in from the ENE almost non-stop and keeping things messy and lumpy. For the first week or so, it's all cross-shore junk with barely any energy, and the swell is short and choppy. You're looking at a blank run from the start all the way through to the 15th of August.
Now, there is a little flicker of hope on the 16th of August. Sunday morning shows a jump in the swell, with a 10ft groundswell out of the ENE. The wind finally swings around to a cross-off from the ESE, which is a massive plus. The combined energy is a whopping 1562, which is a whole lot of ocean movement. But here's the catch – at 10ft, that's big, powerful stuff. With a 10-second period, it's going to be a heavy, lurching wave that's strictly for the experienced crew. On a reef like Windmills, it'll have some serious shape, but the sets will be a handful. The water temp is about average for the time of year, so no surprises there.
After that Sunday morning window, it drops right back off. The wind returns to the east and the swell fades away, leaving us with small, weak, and messy conditions for the rest of the forecast. The 16th of August is the only real highlight, but it's a big, menacing one. Don't get your hopes up for anything else.
Keep it salty.
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.
