The Lowdown
Hey, Rusty here again. Let’s talk Windang Island for the next 16 days. This reef‑and‑point break is only for advanced surfers, and it’s fairly consistent. The run starts flat, then a huge pulse mid‑week, followed by a stretch of clean, manageable waves. Best bet is around the 20th.
Tuesday 14 July – Tiny 0.3ft south swell, 16‑second period, energy 8. Westerly offshore, but barely a ripple. Nothing.
Wednesday 15 July – 10ft south swell, 10‑second period, energy 3228 – that’s a thumper. Cross‑off wind, clean, but only for experts. Tide might be tricky. Marginal.
Thursday 16 July – 5ft south, 8‑second period, energy 333. Cross‑off morning, clean, but rough. Afternoon cross‑shore chop. Not a standout.
Friday 17 July – 3.5ft, 5‑second period, weak. Energy 118. Skip.
Saturday 18 July – 2ft, energy 133. No.
Sunday 19 July – 4.5ft from east‑northeast, 10‑second period, energy 416. Cross‑shore, poor.
Monday 20 July – Here’s the winner. Morning: 5ft east‑northeast, 10‑second period, energy

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.
Windang Island is 7 km (4 miles) from the city of Port Kembla. If you plan a holiday in Illawarra, look for hotels and other accommodation in Port Kembla. Port Kembla has rooms for a wide range of budgets as well as car hire and transport links.
