The Lowdown
Alright, Rusty here. Let’s talk about Windansea.
It’s a bit of a tough stretch ahead, to be honest. We’re looking at a long, drawn-out period of mainly poor surf conditions with only a few moments that might be worth a paddle. The overall energy is weak to moderate for the most part, with the swell coming in from the SW, which is the sweet spot for this reef setup. The water temp is about average for this time of year, nothing out of the ordinary.
Starting things off, Friday the 11th through the weekend is a write-off. We’ve got a 3ft SW groundswell with a nice long 15-second period, and the combined energy is sitting at 461, which is moderate. But the wind is a killer – a strong cross-shore chop on Friday and then it swings cross-on, ruining any chance of a clean wave. Saturday is even worse with onshore wind. You’d be fighting a washing machine out there.
Sunday the 13th morning is the first flicker of hope, but it’s a marginal one. The swell drops to 2ft from the SW with a 13-second period, and the energy is only 234. The winds are light cross-shore, so it might be glassy for a bit, but the wave height is just too small for a decent session. Not really worth getting excited about.
The real potential, if you can call it that, shows up around Sunday the 22nd of September. The combined swell energy ticks up to 673 on Monday the 21st and Tuesday the 22nd, with wave heights around 3ft from the SW, still with a solid 17-second period. This is a very long period groundswell, which at a reef break like Windansea will produce some proper, lined-up waves. The problem is the wind is forecast as a light cross-on breeze, which might just keep it clean enough for a few good ones. It’s marginal, and I wouldn’t want to guarantee it, but it’s the best the charts are offering in this window. Keep an eye on that week.
Honestly, for the next two weeks, there’s no standout session. The winds are wrong more often than not, and the swell is just too inconsistent in quality. The only real takeaway is that the second week has a touch more energy, but it’s all about whether that light wind holds. It’s a waiting game.

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.
