The Lowdown
G’day, Rusty here, lookin’ at the next couple of weeks around Windang Island. It’s a bit of a mixed bag, but there’s a couple of windows where it’ll be worth paddlin’ out. The water’s sittin’ at about 65°F, which is right on average for this time of year, so nothin’ wild there.
We kick off with a pretty flat start. Saturday the 8th through to Tuesday the 11th, it’s mostly small, messy, and blown out. Winds are cross or cross-on, and the swell’s barely ticklin’ 2ft to 3ft. The wave energy is weak, only 79 to 209 (combined energy of all swells directed here). Not worth wettin’ the board.
Then Wednesday the 12th rolls in and it’s still ordinary. Thursday the 13th, though—that’s where it starts to get interestin’. The morning brings a clean 5ft swell from the south, with a period of 9 seconds, and a light offshore breeze. Wave energy jumps to 380 (combined energy of all swells directed here). The afternoon is the real standout: glassy conditions, 5ft of south swell, period still 9 seconds, and energy at 460 (combined energy of all swells directed here). That’s clean, lined-up surf, and it’s the best on offer. Friday morning the 14th keeps it goin’ with another glassy session, 3ft south swell, period 10 seconds, and energy at 227 (combined energy of all swells directed here). The wind’s dead off, so expect smooth faces.
After that, it fades. Saturday the 15th morning is still surfable at 4ft south swell, but the afternoon gets choppy with a strong cross-shore wind. Sunday the 16th through to Wednesday the 19th is mostly weak and messy again, with wave energy droppin’ back to between 43 and 147 (combined energy of all swells directed here). There’s a small window on Thursday the 20th morning with glassy conditions and 3ft ENE swell, but it’s only ordinary.
The second week shapes up a bit better. Saturday the 22nd afternoon sees a bump to 4ft ENE swell, but the wind’s onshore, so it’s marginal. The real long-range promise is Sunday the 23rd morning: glassy, 4ft ENE swell with a period of 11 seconds, and wave energy at 360 (combined energy of all swells directed here). That’s a longer-period groundswell, and it’ll hold up nicely at Windang Island’s reef-and-point setup. The afternoon gets a bit bigger at 5ft, but the onshore breeze will mess it up. Keep an eye on that Sunday mornin’—it’s lookin’ promising but less certain this far out.
Windang Island is a reef and point break, so it handles south and east swell pretty well. The standouts are Thursday the 13th and Friday the 14th, with glassy or light offshore winds and clean south swell. If you’re keen on a longer paddle, Sunday the 23rd morning could be a treat.
Rusty, signing off.

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.
