The Lowdown

G’day, it’s Rusty here. Let’s be straight with you – the next week and a half is going to test your patience. We’ve got a long stretch of poor, messy conditions at Windang Island, with very little on offer. For the first several days, it’s a whole lot of nothing.

We kick off from Saturday, August 15, with a small cross-shore breeze messing up a weak 4.3ft SSE swell (280 combined energy). It’s a write-off. Sunday and Monday aren’t much better – the swell drops and the wind turns cross-onshore, leaving the place choppy and uninviting. By Tuesday, August 18, the surf is almost non-existent, with tiny 1.3ft waves and an onshore breeze. This is the low point.

There’s a brief flicker of hope on Wednesday morning, August 19. The wind goes glassy and we get a clean 3.6ft SE swell (266 combined energy), but it’s short-lived and still pretty small. That’s about as good as it gets for the first week. We then fall back into a few days of tiny, cross-shore slop, with some offshore wind but no swell to show for it.

Then things start to get interesting. Saturday afternoon, August 22, the swell jumps to 6.6ft from the south (518 combined energy), but a fresh cross-shore wind ruins it. The real turning point comes on Thursday, August 27. The swell is pushing 9.8ft from the ENE in the morning, but it’s wild and lumpy. However, by the afternoon, the wind swings offshore from the WNW, and the surf cleans up beautifully – 8.2ft of ENE swell (884 combined energy) with clean, offshore conditions. This is the standout session of the window. Big, powerful, and clean. For experts only, mind you – this is well over 8ft.

Friday, August 28, offers more of that same ENE swell (472-479 combined energy) with offshore wind in the afternoon, staying solid at 6.6ft. Then, the best of the bunch for the second week: Saturday morning, August 29. We get 8.2ft of NE swell (1458 combined energy) and a solid offshore breeze. This is a big, strong, clean day for experienced surfers. It’s our other standout, but it’s a week and a half away, so treat it as promising rather than guaranteed.

The wind stays offshore into Sunday, August 30, but the swell fades to around 3.3ft. So, in short: hang tight through the poor run, and if you’re an experienced surfer, circle Thursday afternoon and Saturday morning on the 29th. The water temp is 64.2°, which is about normal for this time of year.

Windang Island is a reef and point setup, so that long-period groundswell from the SSE on Monday, August 24, is worth a mention – it’s a 20-second period, which is very long and will break a bit too straight for the beach, but this spot can handle it. Just don’t expect much.

Alright, keep it salty.

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.
