The Lowdown
G’day, Rusty here. Windang Island’s a reef and point set-up, exposed to the south-east, so it picks up a bit of ocean energy. Right now, the water’s sitting at about 65°, which is roughly a degree warmer than usual for this time of year – not a game-changer, but it’s a nice touch for the winter.
We’ve got a bit of a slow start. Saturday morning the 1st of August kicks things off with a clean 5ft SSE swell, period around 9 seconds, and glassy conditions with a light SSW breeze. Combined energy is a moderate 356 – solid enough to get the blood pumping, but nothing wild. That morning session is the pick of the early days: clean lines, low crowds possible, and the swell direction is bang on the optimum from the SSE. Later Saturday and into Sunday, the swell drops off or gets chopped up by NNE and NE winds, so don’t bother after lunch.
There’s a real gap through Sunday afternoon, Monday, Tuesday, and most of Wednesday – just tiny bump or blown-out slop, not worth suiting up for. The longest worthwhile break in that stretch is only about 2ft or 0.7ft, with no energy to speak of.
Then Wednesday afternoon the 5th, things switch on. A solid 6ft S pulse rolls in with an 8-second period, combined energy jumps to 837 (moderate-strong), and it’s got a clean cross-off breeze. That’s a standout – bigger, powerful, and the wind’s working with you. Not for learners at that size, but experienced surfers will be frothing. The SE direction isn’t the absolute optimum, but it’s close enough.
Thursday the 6th stays clean with 4ft to 6ft S swell, but the Friday morning the 7th is another gem: 6ft from the SSE, glassy as, energy at 482 – that’s a proper clean session. Saturday the 8th and Sunday the 9th get messy again with onshore winds, so skip those.
Monday the 10th throws a curveball – 6ft NE swell, short 7-second period, but clean cross-off wind from the NW. It’s chunky but a bit short-period, so it’ll be fat and crumbly at a point break – still rideable if you’re keen. Tuesday the 11th has offshore winds but smaller swell.
The real stand-out for the whole run is Friday the 14th of August. That morning you get a solid 10ft E swell, 8-second period, combined energy of 1126 (strong), with a moderate offshore WSW breeze – clean and powerful. That’s expert-only territory at that size, but for the crew who can handle it, it’ll be pumping. The afternoon drops to 7ft but still clean and big. The following weekend (15th and 16th) gets swamped with strong SSW winds and 8ft to 10ft ENE swell, but the cross-off breeze keeps it rideable – just expect it to be rough and a bit wild. Not the best, but if you’re desperate and experienced, there’s waves.
If you’re after the one session to circle, it’s Friday morning the 14th – big, clean, and the wind’s your mate. Early birds win.
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.
