The Lowdown
G'day, I'm Rusty. Look, I've got some mixed news for you. We've got a bit of a flat spell to get through first, but there's a couple of ripper days on the horizon if you can be patient.
The overall pattern for the next couple of weeks starts slow, real slow. From now until the end of this week, we're looking at small, messy conditions. Then, hold onto your boardies, because the following week shapes up with some proper groundswell and glassy mornings – that's where the real action is.
Let's start with the here and now. For the next few days, Windang Island is a write-off. The swell is tiny, and we've got a cross-onshore breeze making a mess of things. On Tuesday the 18th, we get a bit of a reprieve with a glass-off in the morning, but the swell is only 2ft. It's surfable, but you'll be scratching for anything decent. That flat, underpowered run extends right through to Saturday the 22nd. There's a brief moment on Friday morning the 21st where it's glassy with a 3ft swell, but the energy is weak, so it's not going to set the world on fire.
Now, here’s the standout. Keep your eyes locked on Sunday the 23rd of August morning. This is the one we've been waiting for. A solid 8ft south swell hits with a period of 9 seconds. The energy reading is massive, so there's plenty of grunt in the water. That is proper wave energy. The wind is light and cross-offshore from the north, making for clean, lined-up waves. This is excellent surf, but at that size it's strictly for the experienced crew. Beginners, sit this one out.
After that pulse drops, we still have some fun, smaller swells through the start of the following week. Monday the 24th has clean 4ft conditions in the morning with an offshore breeze, and Tuesday the 25th looks choice too: glassy in the morning with a 6ft south swell, and then cleaning up even more in the afternoon with a strong 16 mph offshore wind from the west.
Windang Island is a reef and point break, which is perfect for these south swells. It's an exposed spot, so it grabs the energy well. It can draw a crowd though, and breaking is on offer for the Sunday standout, so get in early. The water temp here is running about average for this time of year, so your 3/2 steamer will be fine.
For the second week, the swell hangs in there but gets a bit smaller. Wednesday and Thursday mornings have those strong offshore winds (19 mph +), but the swell drops to 5ft to 4ft. The energy is still moderate, but those strong winds can make it a bit tricky. After that, it fades back out with small, choppy conditions to close out the month. Overall, despite the quiet start, that Sunday morning on the 23rd is your absolute best bet – set the alarm and don't sleep in.
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.
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.
