The Lowdown
G’day, I’m Rusty. Let’s have a proper look at what’s coming up for Windang Island.
Right now, the surf is pretty ordinary, and it stays that way for the first few days. Monday morning has a weak 4ft swell from the NE, short period of 7 seconds, with a light northerly cross breeze and combined energy of just 283 – not much happening. The water is 65°, which is pretty normal for this time of year. That small NE swell fades fast, and Monday afternoon drops to a tiny 2ft from the S with a choppy onshore wind. Tuesday and Wednesday morning are still quiet, with small, messy swell and poor conditions. Honestly, not worth paddling out.
Then things start to get interesting. Wednesday morning the 16th sees a jump to 8ft from the S, period 10 seconds, and a fresh SSW cross-off breeze that keeps it clean. The combined energy hits 1391 – moderate to strong – but the size and that wind direction will make it a bit tricky. It’s really for experienced surfers only at that size. The afternoon gets even bigger, 10ft, but the wind swings and turns it lumpy. Still, there’s potential for those who know the break.
Thursday morning the 17th is the real standout. Clean 10ft S swell, 10-second period, light SSW cross-off wind, and the combined energy is 2674 – that’s strong, powerful surf. The conditions are described as excellent for experienced surfers. This is a proper session for the advanced crew at Windang Island, with a solid south swell running and clean lines. The wind is light, the surf is pumping, but it’s big – not for beginners.
That afternoon the swell backs off a bit to 7ft, but the wind turns cross-onshore and the quality drops. Friday and Saturday are much smaller and not worth getting excited about, though Saturday morning the 19th offers a brief moment of glassy 2ft S swell – tiny but clean for a longboard if you’re desperate.
The second week brings more size but more mess. Sunday the 20th is flat, but Monday the 21st sees another big pulse: 10ft from the S, 10-second period, combined energy of 2128, but it’s cross-onshore and choppy. Not great for paddle surfing, but that kind of setup might appeal to the kite crew. Tuesday the 22nd holds 7ft with a longer 12-second period from the SSE, combined energy 1142, but the cross-shore wind keeps it from being clean.
The best bet in the second week is Wednesday morning the 23rd. Glassy conditions, 4ft SSE swell with a long 12-second period, combined energy 382 – not huge but clean and lined up. That long period groundswell will wrap nicely into Windang Island’s reef and point setup. The wind is glassy, the conditions are good, and it’s a much more manageable size. This is the one to circle for the second week.
Overall, Thursday the 17th morning is the absolute standout – big, clean south swell for experts. Wednesday the 23rd morning offers a more relaxed but still quality session with glassy conditions and long-period groundswell. The rest of the period is a mix of small stuff or big but messy. Keep an eye on the forecasts – things can change.
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.
