The Lowdown

Alright, listen up, the surf's gonna be a slow starter, but there's a proper firecracker waiting for you if you're patient.

We're looking at Windang Island, a solid reef and point setup. The water's sitting around 64°, which is pretty much average for this time of year, nothing unusual there.

First few days are a bit of a write-off, honestly. Tuesday the 1st kicks off with small, weak 3ft S swell, but the wind's all wrong, cross-shore and messy. The energy's weak (174), and it's just not worth paddling out for. Wednesday and Thursday are similar – tiny bits of swell, but squeaky clean with offshore winds, so you could get a few grovelly ones if you're desperate, but it's tiny. Friday the 4th morning shows a little more life with a clean 3ft S swell and a bit more energy (144), but it's still small.

Then we hit a proper flat spell. Friday afternoon, all through Saturday, the swell drops right out. You're looking at 2ft or less, and the energy figures are pathetic (44, 64, 46). It's a total lake. You'd be better off cleaning the wax off your boards.

Sunday the 6th is where things start to get interesting. The morning is glassy, dead calm, and we've got a 4ft S swell rolling in with a solid energy reading of 335. That's a great sign. The combo of glassy, clean conditions and a bump in size makes it a genuine standout for a fun session. The afternoon gets chopped by a cross-onshore, so make it a dawn patrol.

The week that follows is a mixed bag of onshore slop and small, average waves. It's not great, but you'll see some waist-high options with the odd clean window if the wind plays nice.

Now, hold onto your board shorts. The real gold is waiting for you on Wednesday the 9th of September. The afternoon is a monster. We're talking a 10ft S swell, with a period of 11 seconds and a massive energy reading of 3057. That's a whole lot of water moving. The wind is moderate and offshore, so it's going to be clean and powerful. This is big, serious swell. Over 8ft, so this is for experts only. Do not take a foamie out here.

That big energy keeps pumping through Thursday the 10th and into Friday the 11th, but the wind gets messy. However, Friday morning the 11th is another absolute standout. The swell is still a solid 10ft, but now it's SSE, with a very long period of 13 seconds, and the energy is through the roof at 3070. The wind is light and cross-offshore, making it clean. This is a proper groundswell – long lines, heaps of energy, and longer waits between sets. That long period makes it perfect for a point break like Windang Island, but it'll be too straight and fast for a beach break. Friday afternoon goes glassy with the same size swell, which is a dream scenario.

The weekend gets a bit unruly with strong winds, but the size sticks around for the crew who can handle it. Monday the 14th morning is a treat for the brave – a much cleaner 5ft ESE swell, glassy conditions, and a nice energy reading of 564. That's a solid, fun day.

The last few days of the outlook see the swell dropping back down, but Tuesday the 15th afternoon serves up a clean 6ft S swell with 626 energy and offshore winds, and Wednesday the 16th morning is a clean 5ft S swell. Solid, consistent waves to finish on.

So, the standout picks? Without a doubt, the Sunday the 6th of September morning for a clean, fun, glassy session as the swell begins to build. Then, the absolute best of the bunch is Wednesday the 9th of September afternoon and Friday the 11th of September. That's proper, expert-level groundswell with clean winds. The long period means the sets will be a bit more spaced out, which makes paddling out easier, but when they come, they'll be meaty. It's a point break, so it'll handle that energy beautifully. Just be aware crowds are possible at this spot.

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.
