Table - best surf conditions forecast for Windang Island over the next 16 days.
G’day, Rusty here. Let’s break down what’s coming for Windang Island.
Right now, it’s a flat start. Sunday the 12th through Tuesday the 14th, the swell is tiny – 2ft down to 0.3ft – and the conditions are poor. Leave the stick at home.
Then Wednesday the 15th morning, a solid south swell hits at 8ft, with a short period of 8 seconds. The combined energy is strong at 1561, so there’s plenty of power, but it’s only for the experts. The wind is cross-offshore from the SSW, so it’ll be clean, but it’s a beast. The afternoon gets messy with cross-shore wind.
Thursday the 16th and Friday the 17th are smaller – 6ft to 5ft – with cross-off wind, so clean but not special.
The big standout is Monday the 20th morning. A solid 7ft easterly swell with a nice long period of 11 seconds. The energy is strong at 1123, and the wind is a light cross-off from the NNW, keeping it clean. The swell direction (E) lines up with the optimum (SE) perfectly for the reef and point. This is the best call – solid, powerful, and clean. Crowds can be an issue here, so get in early.
Tuesday the 21st is a gem. The morning has 6ft east swell, 11-second period, and light offshore wind from the WSW. The afternoon goes glassy with almost no wind – that’s a treat. The energy is good (734 to 815), and it’s clean all day.
Wednesday the 22nd morning keeps it going with 5ft east swell, a very long period of 13 seconds, and light offshore wind. The energy is strong at 1355 – a proper groundswell.
Thursday the 23rd morning fires with 7ft southerly swell, 10-second period, and light cross-off wind from the NNW. The energy is huge at 1773, and the swell direction matches the optimum (SE) well. Only for the experienced crew.
Friday the 24th afternoon brings a nice 5ft east swell, 12-second period, strong offshore wind from the W, and big energy at 1022. Clean and solid.
From the 25th onward, the swell backs off but stays clean with offshore winds, fading to 2ft by Monday the 27th afternoon.
Water temp at the start is 65°F, which is 2°F warmer than average – a nice little bonus for winter.
The standout is Monday the 20th morning – 7ft east swell, 11-second period, clean cross-off wind, and energy pumping. Tuesday the 21st is a close second, especially that glassy afternoon.
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.
