The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Windmills over the next couple of weeks.
Honestly, the outlook is a bit of a tough one. We’ve got a lot of days where the wind is just not playing ball, blowing straight cross-shore from the ENE and making a mess of things. The first few days are a write-off, with poor surf conditions and lumpy cross-chop. The water here is sitting at 80°, which is pretty much bang on average for the time of year, so no surprises there.
The first real glimmer of hope comes on Monday the 7th. The morning is still a bit iffy with a cross-off wind and 5ft swell from the ENE, but it’s clean. The real standout, though, is Monday afternoon. We get a solid 7ft swell rolling in from the WSW, with a period of 15 seconds. That’s proper groundswell, and with a moderate cross-off breeze, it’s going to be clean. The energy is strong at 2595 (moderate wave energy). This is a reef break, so that long period, straight swell will wrap in nicely. It’s an advanced spot, and it’s fairly consistent, so you’ll get waves. Be aware that it’s often crowded, so you won’t be alone out there.
Tuesday the 8th morning is also a good shout. We’ve got offshore wind from the S, blowing at 12 mph, keeping things glassy. The swell is 6ft from the WSW, period 11 seconds, and the energy is 1267 (moderate wave energy). The forecast rates it as very good surf conditions. This is your best bet for clean, groomed waves.
After Tuesday, it’s back to the ENE cross-shore grind. The swell drops off, and the wind picks up again, so we’re looking at a long stretch of poor to marginal conditions. The second week is a bit of a desert, with the same pattern of ENE wind and lumpy sea state. Thursday the 16th morning has a clean look with a cross-off wind, but the swell is still mixed up and the energy is low.
Bottom line: If you’re a confident surfer, this is a two-day window. Mark your calendar for Monday afternoon and Tuesday morning. The rest of the window is a pass for paddle surfing; the conditions are more suited to a kite session with that consistent cross-shore wind.
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.
