The Lowdown
Alright, mate, Rusty here. Let’s have a look at what’s comin’ down the line for us.
Honestly, it’s a bit of a rough start. The first few days are pretty much a write-off. We’ve got a fair bit of swell energy, but the wind is just mucking it up. The whole first week is a struggle, with cross and cross-off winds from the ENE blowing at 20 to 22 mph, just chopping everything up. It’s not until the 7th of September that we even see a hint of something rideable, and even then it's marginal.
The best of a bad bunch, and really the only standout in the whole 16-day window, is Windmills (reef) on the afternoon of the 14th of September. The waves are gonna be around 7 ft from the ENE, with a period of 8 seconds. The wind is gonna be a light cross-off from the East at 9 mph, which should keep things pretty clean. The combined swell energy is moderate (575). It’s a Monday, so the crowds might be a bit less, though it can get busy there. The rest of the time, the wind is just too strong and from the wrong direction to make anything of the decent swell that’s around.
The water temp is a warm 80°, which is pretty much bang on average for this time of year.
We do have some bigger pulses of energy, like the 7 ft and 6 ft swells earlier on, but with 15-22 mph cross-shore winds, it’s just a mess. For a reef break like Windmills, you need the wind to cooperate, and it just doesn't for most of the forecast. The long period swell on the 10th and 11th of September (14 and 12 seconds) would be a dream at a reef, but the wind is just too strong and from the wrong angle. It’s one of those forecasts where you just have to be patient and wait for that one window on the 14th.
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.
