The Lowdown
Alright, Rusty here again. Let’s talk Windang Island in feet and degrees.
We’ve got a slow start, but there’s a couple of days that’ll get your heart rate up. Early on it’s cross-off wind and junk surf, so don’t bother paddling out until Tuesday afternoon (11th August). That afternoon brings a clean 4ft S swell with 11-second period, offshore wind from the W at 15 mph, and combined energy is moderate (478). It’s rideable but just a warm-up.
Thursday morning the 13th is the first real standout. Clean 6ft S swell, 9-second period, light offshore from the SW at 6 mph, with strong energy at 524. This is the kind of morning that has you checking your wax job before dawn. The reef and point setup at Windang Island will be working nicely. For a break that’s fairly consistent, this is your best bet in the first week.
Now look ahead to Sunday the 23rd of August. Morning delivers a solid 6ft NE swell, period of 9 seconds, and combined energy cranks up to strong (1054). That’s a lot of water moving. Wind is light offshore from the WNW at 6 mph, forecast excellent for experienced surfers. This is the big one. The same afternoon goes glassy with 5ft ENE swell. For the advanced crew, that morning session is the one to save for.
Water temps are about average for this time of year at 64°, with a minor 1° anomaly – nothing to fuss over.
There are gaps: after Thursday the quality drops into marginal or poor surf, with small, short-period, choppy days through the weekend and into the next week. Not much happening until that Sunday the 23rd lights up. Then Monday the 24th offers clean but more ordinary 4ft E swell.
Be patient. The windows to watch: Tuesday 11th afternoon for a fun one, Thursday 13th morning for something cleaner and punchier, and the big standout – Sunday 23rd morning – for experienced surfers wanting a proper hit.
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.
