The Lowdown
Alright folks, Rusty here. Let's have a look at what Windansea is doing over the next couple of weeks.
To be straight with you, the outlook for Windansea over the next sixteen days is pretty grim. We're looking at a solid run of poor surf conditions, with hardly any windows of quality. The swell is there, but it's almost always battling the wrong wind direction, leaving it choppy and messy.
Monday the 14th kicks things off with a bit of energy – the swell’s around 4 to 4 ft from the west with a combined energy of 405, but that cross-onshore wind from the SSW at 9 mph is just ruining it. It’s gentle cross-onshore and fairly choppy. Not worth paddling out for.
Through Tuesday and Wednesday, the swell drops, and while we see a few longer period swells – up to 20 seconds on Tuesday afternoon – that only makes things trickier at a spot like this. Windansea is a reef break, so those long period groundswells can actually wrap in nicely here, but the cross-onshore wind just kills the potential. The water temp anomaly is about average for this time of year, so no surprises there.
From Thursday the 17th right through to the end of the month, it’s the same story: small swell, mostly in the 2 ft to 3 ft range, combined energy floating between 280 and 498, but almost always with a cross-on wind. The only faint glimmer is that by the morning of the 21st of September, the rating hits a meager 2/10, and the swell is a consistent 3 ft from the SW with a 17-second period, and it's glassy with light onshore wind – that's about as clean as it gets in this stretch. For a couple of sessions around that Monday, the 21st, you might catch a few lined-up but weak waves if you’re desperate.
The second week, from the 22nd onward, it’s flat and unremarkable. Swell direction stays SW, period drops, and the wind, while lighter, stays onshore or cross-onshore. Nothing to get excited about.
Truth is, there’s no real standout here. If I had to pick the closest thing to a session, I’d say the morning of Monday the 21st of September is your best bet – small 3 ft SW groundswell with a 17-second period, light glassy conditions, and at Windansea that long period might offer a few clean lines. But don’t expect much – it’s a marginal call at best.
Rusty.

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.
