The Lowdown
G’day, Rusty here. Let’s have a look at what’s on offer for Windang Island over the next couple of weeks.
Right off the bat, the first few days aren’t really worth paddling out for. Friday the 17th and Saturday the 18th are small and junky – we’re talking waist-high slop with short-period swell and poor conditions. The water’s sitting at 65°, just a touch warmer than normal for this time of year, but that’s about the only highlight.
Sunday the 19th shows a bit of a pulse, with swell building to 6 ft from the ENE, and the combined energy kicking up to 786 (moderate), but the wind is cross or cross-onshore, and the forecast calls it marginal. Keen surfers might find a few, but it’s nothing to plan a session around.
Now, Monday the 20th morning is where things start to look up. The swell drops slightly to 5 ft, still from the ENE, but the wind goes cross-off from the NNW with a light breeze. The combined energy is 542 (moderate), and the wave comment says expect very good surf conditions. This is the best of the early run – clean, solid head-high waves, and the reef-and-point setup at Windang Island should handle that ENE swell direction nicely. Crowds are noted as “sometimes,” so you might have a few others out, but it’s worth it.
The rest of that week stays in the background. Tuesday the 21st morning goes glassy with 4 ft ENE swell (combined energy 337), but it’s small and clean for a quiet session. Thursday the 23rd morning offers another glassy moment with 5 ft S swell, but it’s a shorter period and the energy is only 219, so it’s more of a fun-sized wave than a standout.
The real standout pops up on Thursday 31st July morning. The swell jumps to 8 ft from the south, combined energy hits 2419 (strong to very strong), and the wind is cross-off from the NNW with a moderate breeze keeping it clean. That’s a solid, powerful groundswell with a 10-second period, which at this point break will mean some heavy, well-shaped waves. But listen – at 8 ft, this is expert territory only. Not for beginners. Crowds are possible, but with that size, the lineup will thin out. This is the one to circle on the calendar.
After that, the first of August backs off quickly. Saturday morning the 1st has 5 ft from the SSE with offshore wind, and the combined energy is 233 (moderate), so it’s a clean, mellow drop-off from the big day before. Still a fun morning session if you’re hanging around.
The long-range stuff around the 29th and 30th of July shows building swell and clean conditions, but it’s still marginal in quality – promising but not locked in.
Overall, if you’re a strong surfer, the 31st of July is the clear winner. For everyone else, Monday the 20th morning is your best bet for a clean, solid session without the heavy vibes.
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.
