The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this 16-day stretch for Windmills is a total write-off. I’ve looked through every day from July 16 through to July 31 and there’s not a single recommendation worth paddling out for. The finder’s telling me it’s all “poor surf conditions” with a score of zero, and that’s the truth.
Windmills is a reef break for advanced surfers, fairly consistent and fairly exposed, with an optimum swell from the NNW. But the wind is the killer here – it’s coming cross-shore from the ENE almost the entire forecast, blowing at 12 to 19 mph (20-30 km/h). That’s a moderate to fresh breeze kicking up lumpy cross-chop. The swell sizes float between 2 ft and 6 ft (0.5-1.7m), with periods mostly short (5-8 seconds) meaning weak, choppy waves. Even when the energy picks up – like on the 28th and 29th July when combined energy jumps to 615 and 644 (moderate to strong) and the period stretches to 13 and 11 seconds – that longer-period groundswell might have some push, but the wind still spoils it. That cross-shore mess means the wave face stays bumpy and ugly. For a reef that needs clean conditions, it’s just not happening.
The whole 16 days are a blank run. Nothing stands out. No morning glass-offs, no offshore windows. Even the few times the swell gets over 5 ft (like 6 ft on the 25th and 26th) it’s still accompanied by that cross wind, so it’s not even worth thinking about for advanced crew. If you’re a kite surfer, that constant cross-breeze might be your thing, but for paddle surfing – forget it.
Look, Windmills is a fairly consistent spot, so it’s a bit unusual to see such a long dry spell. Forecasts can change. But right now, you’d be better off staying home and waxing your board for another day.

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.
