The Lowdown

G’day, Rusty here. Look, I’ll be straight with you – the next 16 days at Windang Island are a bit of a mixed bag, and honestly, there’s not a whole lot of quality surf on offer. The first few days are a write-off, and we’ve got a long stretch of ordinary conditions before we even get a sniff of something decent. Let’s break it down.

We start on Wednesday, 9 September, with a sloppy 3 ft southeast swell at 8 seconds, but the 20 km/h cross-off wind from the SSW isn’t doing much for it. The water’s sitting at 64°, which is about average for this time of year. The combined energy is weak (133), and the waves are just poor. It’s not worth paddling out. Later that afternoon, the swell jumps to 8 ft – that’s too big for beginners and pushing into expert territory – but the 35 km/h southerly cross-wind is going to turn it into a lumpy mess. No thanks.

Thursday, 10 September, morning sees a 8 ft south swell at 10 seconds, with a better 15 km/h cross-off wind from the SSW. The combined energy is strong (2063), but the forecast calls it marginal. The size is still hefty for most, and the wind is just okay. It’s a pass for me. The afternoon drops to 6 ft from the SSE, but the cross-shore wind makes it choppy.

Friday, 11 September, and Saturday, 12 September, are all small – 5 ft and 3 ft – with weak energy and cross-shore or cross-onshore winds. The waves are marginal at best, and the afternoons are poor. By Sunday, 13 September, we’re down to 2 ft and 2 ft south swells, with cross-onshore winds. It’s a wasteland. Monday, 14 September, through to Wednesday, 16 September, are tiny – 2 ft to 3 ft – with light winds, but the surf is just ordinary. The combined energy barely cracks 200.

Now, Thursday, 17 September, morning finally offers a glimmer. A 3 ft south swell at 9 seconds with a 10 km/h WSW cross-off wind. The combined energy is 179 – weak – but the wind is clean, and the waves are “surfable but very ordinary.” It’s a small, clean option, but nothing to get excited about. The best window in this whole 16-day run? It’s a stretch, but I’d say Thursday, 10 September, morning had the most size and energy (2063), even though it was marginal. If you’re an expert and can handle the 8 ft south swell, it’s the only standout. The offshore wind direction is SSW, which is reasonable for the break’s optimum southeast swell direction, but the cross-off wind isn’t perfect.

We then hit another gap of poor tiny surf through Friday, 18 September, to Sunday, 20 September, with 1.0 ft to 4 ft swells and cross-shore winds. Then Monday, 21 September, brings a 30 km/h offshore wind from the west, but the swell is only 4 ft and short-period (7 seconds). The energy is weak (165), and the forecast says poor. It’s clean but gutless. The rest of the period through 24 September is a mix of small, short-period swells from the ENE and NE, with cross-onshore winds, and a final 8 ft south swell on the afternoon of 24 September with fresh cross-winds – lumpy and poor.

Overall, there’s no real quality surf here. The standout is the 10 September morning session for experts only, due to the size and energy, but it’s still marginal. For most of us, it’s a long, flat run. Keep an eye on the forecasts, but don’t expect much.

Rusty.

Information about the Windang Island Surf forecast

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