The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the menu for the next couple of weeks.
Honestly, it’s a pretty grim stretch for a solid surf. We’ve got a long, long gap of nothing but junk to start. The first real chance of anything decent doesn’t roll in until Tuesday the 8th of September, which is over a week away. Before that, it’s all cross-shore winds and lumpy, weak surf. The wind is a relentless ENE, blowing at 12 to 22 mph, trashing any shape. You’ll see swell heights around 5 ft to 6 ft, but it’s all short-period, close-to-the-wind chop. The combined energy of all swells directed here stays low to moderate (under 300), so it’s a lot of push with no power. Not worth paddling out.
Now, the standout. The morning of Tuesday, September 8th is the one bright spot. Windmills will wake up with a proper pulse. That’s the day to go. The swell jumps to 8 ft, and it’s coming from the WSW, which is a good direction for this reef. The period is a very long 15 seconds, giving it serious groundswell grunt, and the combined energy of all swells directed here hits 3533 – that’s strong, powerful energy. The magic is the wind: a clean 12 mph offshore from the SSE, grooming the faces. This is excellent surf, but it’s for experienced surfers only. That 8 ft on a reef with that energy is serious. The afternoon will drop off quickly in size, and the wind will shift, so get it in the morning. The water temperature is about 80°, which is pretty much average for the time of year.
The rest of the second week? More of the same ENE cross-shore nonsense. Wednesday the 9th through to the 17th is a write-off – poor surf conditions, lumpy cross-chop, and the wind just won’t get out of the east. There are a few days with a marginal surf forecast, but the quality just isn’t there. The waves are small, the energy is weak, and the wind is wrong. It’s a long blank run after that one good morning.
So, mark your calendar for the 8th, get out early, and be on your game. The rest of the month is a poor bet for a paddle.
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.
