The Lowdown
G’day, it’s Rusty.
Alright, let’s have a yarn. The next couple of weeks around Windang Island ain’t exactly lighting the world on fire. There’s a proper flat spell at the start, so don’t rush out. The first week is mostly dribble—small, weak swell and onshore breezes turning things to mush. You’re looking at a solid stretch of poor surf from now until the 21st or so, with barely a wave over 2ft and most of it under that. Not worth the walk.
Thursday morning gives you about 4ft of south swell at 9 seconds, with a light cross-offshore wind that keeps things tidy. But the energy is only moderate (221), and it’s not a patch on what you’d want. Friday morning goes glassy with 3ft at 8 seconds, but it’s ordinary and slow. From there, it’s a downhill slide—cross-on winds, sub 4ft waves, and periods dropping to 6 seconds. The weekend of the 16th and 17th is a washout; the energy just bleeds out to nothing.
We get a slight reprieve Sunday the 23rd when a moderate offshore wind (around 15 mph) cleans up a dribbly 3ft ENE swell. It’s small, but it’s clean and rideable on the point. That carries into Monday the 24th, which is the pick of the bunch—offshore breeze, same 3ft groundswell from ENE at 9 seconds, and the energy jumps to 200 in the morning. That’s the most user-friendly, lined-up and clean you’ll get all week. Tuesday is still okay in the morning, but it falls apart by the afternoon.
Then things get interesting for the experts. Thursday the 27th sees the energy spike to 307 with a 4ft south swell, but the wind is howling at 22 mph from the SSW—it’s cross-off so it’s clean, but it’s strong and messy. Friday the 28th brings the biggest swell of the window: 5ft from the south at 11 seconds, and the energy is strong at 642. That’s proper groundswell. But the wind is a fresh cross-shore at 19 mph with rain, so it’s going to be lumpy and cross-chop. Too big for beginners, and even for the advanced, it’s going to be a fight. This one’s for the experienced only.
Water temp is 18°, about average for this time of year, so no surprises there.
So, bottom line: if you want an easy session, Monday the 24th is your best bet—small, but clean and a bit of energy. Friday the 28th is for the bigger-wave crew, but be ready for rough conditions. The first week is a write-off, so don’t hold your breath. The longer-range stuff looks promising but less certain. Keep the faith, but don’t force it if it’s crap.
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.
