The Lowdown
Alright, Rusty here. Let’s break down what’s on the horizon for Windansea.
It starts off pretty slack. For the first few days, from Friday the 21st of August through the 25th, the surf is flat or just too small to bother with. The water is sitting at about 70°, which is a touch warmer than typical for the season, but that’s about the only good thing. The waves are tiny and weak, even with the morning offshore flows, so save the wax.
The first sign of life creeps in on Wednesday the 26th of August. The morning shows a jump to 6ft from the SSW with solid period. The energy is strong (1600), but the wind is swinging cross-shore at a moderate clip, which puts a choppy top on it. Not the classic Windansea you’re hoping for, but it’s a sign that something is on the way.
The clear standout of the whole forecast is the afternoon of Thursday the 3rd of September. The swell holds at a clean 3ft from the south, with that long period, and then you get that glassy wind – a slight air. That’s the magic ingredient for the reef. The combined energy reads a solid 592, and it’s coming from the right direction. That’s your golden hour.
After that, Friday the 4th of September sees building swell, pushing 5ft to 5ft from the south, but with a side-onshore breeze that messes with the surface. Then Saturday the 5th of September brings the real muscle, with waves hitting 7ft from the SSW and long, powerful periods. The morning offshore wind is back, but that size is for experienced hands only. It’s a big groundswell, so think reef privileges and expert crowds.
The second week is more of a waiting game, but that Thursday glass-off is the real deal. Everything after that gets bigger and a little more unruly.
Rusty out.

Information about the Windansea Surf forecast
The above surf forecast table for Windansea provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Windansea can be found by selecting the local surf guide option on the grey menu. Our Windansea 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 (Windansea) 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 Windansea 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.
