The Lowdown
G’day, it’s Rusty. Okay, let’s run through this same window for Windang Island.
The early part is a write-off. We’re talking knee-high slop with pitiful energy (91-115) and wind all over the shop. Thursday morning is clean with a light offshore, but it’s only 3ft at 8 seconds – you’d be scratching for one. Friday and Saturday mornings are clean too, but still tiny. Water temp is 65°, about a degree and a half warmer than usual, so it’s not bad for this time of year.
Then Sunday the 10th goes nuts with a 50 km/h westerly – that’s a near gale offshore. There’s a bit of energy in the water (365), but it’s a futile paddle. Monday the 11th is small and clean but still not worth suiting up for.
The first sign of life is Friday the 14th. Light cross-offshore breeze, 4ft of S swell at 9 seconds, and clean. Energy is up to 265. Then Friday afternoon goes dead glassy – no wind, 4ft of S swell. That’s a lovely, clean window. This is a real option.
But the pick of the fortnight is Saturday the 15th morning. 5ft of S swell at 10 seconds, a light SSW cross-offshore, and the energy is pumping at 529. This is the one. For a south swell on a reef and point, it’ll be holding up nicely and it’s got power. Over 5ft – not for beginners, but proper surfers will be onto it. Expect some company, as crowds are sometimes there.
Saturday afternoon the wind kicks up to 35 km/h from the SSW and it ruins it. Sunday the 16th is a total washout with fresh cross-shore winds and lumpy chop.
Everything after that just fades. Monday and Tuesday are small and clean but with no drive. Then we get a few days of total dribble, with almost no energy (45-71). Thursday the 20th has a bit more size (3ft) but it’s onshore and choppy.
The last possible thing is Friday the 21st – 7ft of SSE swell at short, 8-second period, with an onshore breeze. Big and messy, not worth it in my books.
So the call is simple: Saturday the 15th morning is the standout. Friday the 14th afternoon, glassy and clean, is your backup. Otherwise, it’s a quiet two weeks.
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.
