The Lowdown

G'day, Rusty here. Let's have a look at what's shaping up for Windang Island. This is a solid reef and point break that's fairly consistent, so it's worth a look. The water temp is 65°, which is a touch warmer than normal for this time of year, so you might not need the thickest wetsuit.

The fun starts on Friday, July 31st. The morning session is the pick of the early days. We've got a 5ft south swell, with a 10-second period, and a light cross-offshore breeze from the SSW. The combined energy is a solid 474, so there's a bit of power. It's clean, and the swell direction is coming from the south, which is not quite the ideal SE, but it'll still be fun.

Later that afternoon, the swell jumps to 7ft, also from the south, but the wind goes side-shore, and the energy kicks up to 1206. It's a bit more of a handful, but still surfable if you're confident.

Moving into Saturday, August 1st, the morning has a clean 5ft swell from the SSE, with light cross-offshore winds again. The energy is moderate at 342. But the real winner is Saturday afternoon. The wind drops to glassy, a 5ft SSE swell, and the energy is a healthy 316. That's the kind of session you dream about – clean, glassy, and a perfect size.

Sunday morning, the 2nd, sees a 5ft SE groundswell with a long 12-second period, which is a beauty for a point like this. The energy is a solid 666. The wind is a light cross-shore, so it's manageable. But the arvo gets blown out with a strong onshore, so get in early.

Monday the 3rd is a drop-off, with small 3ft swell, and the rest of the week looks pretty marginal. There's a bit of a lull through the middle of the week, with some small clean days but not much push.

Then, we get a couple of standouts in the second week. On Wednesday, August 12th, the morning has a 3ft ESE swell with a 10-second period, and the wind is a solid offshore from the W. The energy is 224, and it's clean. It's not huge, but the conditions are good.

And then, brace yourselves. Saturday, August 15th, we've got a monster coming. The morning is forecasting a 15ft SSE swell, with an 11-second period. The energy is a massive 4837. The wind is a light cross-shore, so the conditions are tempting. But let's be clear, this is a big one. Over 8ft, it's for experts only. The set-up is a reef and point, so it might handle that size, but it's going to be a serious challenge. The afternoon is a bit smaller at 13ft, but still a beast. If you're not an absolute charger, stay on the beach and watch the show.

Overall, the best bet is Saturday afternoon, August 1st, with that glassy 5ft swell. The other standout is that big Saturday the 15th, but that's a wild card for the brave only.

Rusty, signing off.

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.
