The Lowdown
G’day, I’m Rusty, and I’ve been staring at the charts for Windang Island. Let me tell you, it’s a bit of a slow burn, but there’s a couple of windows worth paddling out for. This spot is a reef and point setup, always demands a bit of respect, especially when the swell gets serious. The water temp is sitting at 64°F, which is about bang on for this time of year.
Right now, we’ve got a bit of a quiet spell. Tuesday afternoon kicks things off with a 6ft SSE swell, but the period’s only 8 seconds, combined energy is moderate (462), and the wind is light onshore. It’s marginal at best. Wednesday morning brings a drop in size to 3ft with a 25 km/h cross-off wind, but the conditions are rated poor. That afternoon, it gets ugly – 8ft of S swell with 35 km/h cross winds making for a lumpy mess. That’s too big for beginners and only for the experienced crew, but the quality is shocking.
Thursday looks a bit better. Morning has 8ft S swell, 10-second period, and cross-off winds. The combined energy is strong (1133), but the conditions are still marginal. The afternoon sees the same size with cross winds. Not the cleanest. Friday and Saturday are similar – inconsistent, 3ft to 6ft SSE swell, but the wind is messy, cross or light onshore. This whole first week is a write-off for clean waves.
Now, here’s where it gets interesting. The standout is Monday, 21 September. That morning, we’ve got a solid 6ft S swell with a 9-second period, combined energy at a strong 533, and offshore winds from the WSW at 20 km/h. The description says “very good surf conditions.” The swell direction is SSE, which is close enough to the optimum SE direction for this break, and that offshore wind means clean, groomed faces. This is the pick of the window – a proper session for the advanced crew. That afternoon, the wind swings cross and the quality drops.
Before that, Wednesday, 16 September morning offers a little taste. It’s small at 3ft S swell, 10-second period, but the wind is glassy – dead calm – which is a major positive. Combined energy is moderate (261), and the conditions are “good.” It’s inconsistent and small, but if you’re desperate for a clean, small-wave board, it’s worth a look. The 18th Friday morning also has clean 3ft S swell with cross-off winds, and Friday afternoon sees a tiny 2ft SSE swell with a long 15-second period and offshore wind. That’s more of a longboard or glide session.
The second week is patchy. 20 September Sunday has clean options: 3ft S swell with cross-off winds in the morning, and 2ft S swell with offshore winds in the afternoon. Not huge, but rideable. Then that Monday 21st is the real highlight. After that, it fades fast – 22 September drops to tiny 1ft SSE swell, and it’s all cross-onshore or onshore winds through to the end of the window.
Crowds at Windang Island can sometimes be an issue, so on that Monday 21st, expect a few locals to be stoked on the same idea. Summing it up: there’s a long dry patch right now, but the 16th morning offers glassy small waves, and the 21st morning is the one to circle on your calendar. It’s not a total blank run.

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.
