The Lowdown

G’day, I’m Rusty. Look, I’ve got to be straight with you – this Windang Island stretch is going to be a frustrating wait for most of the next fortnight. The first few days are pretty grim, with tiny waves and tricky winds making it hard to get excited. Then there’s a long, quiet gap until we finally see something worthwhile. The standout is a real beauty, but you’ll need patience.

Starting off, the weekend of August 29th and 30th offers nothing to write home about. Saturday morning sees a weak 4ft SSE swell, but it’s cross-shore with a combined energy of just 358 and it’s described as marginal – honestly, not worth paddling out for. Sunday morning improves slightly with a glassy 3ft S swell, period around 9 seconds, and the water temperature sits at 64°, which is about average for this time of year, but the wave energy is weak at 222.

From Monday the 31st right through to Sunday the 7th of September, it’s pretty much a write-off. The swell drops to knee-high or less, winds are mostly onshore or cross-shore, and the scores are poor. There’s a tiny window Wednesday the 2nd afternoon with a 2ft S swell and clean offshore wind from the west at 9 mph, but wave energy is barely 95 – it’s surfable but very ordinary. The rest of that week is flat or messy.

Then we hit a real standout: Tuesday the 8th of September. The afternoon brings a solid 6ft S swell with a period of 12 seconds (that’s groundswell) and the combined energy jumps to 1116 – moderate to strong energy. Offshore winds from the west at 25 mph are strong, meaning it’s clean but hard work paddling into. This is advanced territory; beginners should sit this one out.

But the absolute best session on offer is Thursday the 10th of September morning. Glassy conditions with an ESE breeze at just 3 mph, a clean 6ft SSE swell, period 12 seconds, and wave energy at 997. The optimum swell direction is SE, and this is coming from the SSE, so it’s a great match. This is a reef and point break, so that long-period swell will link up beautifully. It’s fairly consistent here, but crowds are possible – be ready to share.

By Friday the 11th of September morning, it’s still clean and glassy with a 4ft SE swell and period 12 seconds, energy at 402 – a nice follow-up for those who want a quieter session.

After that, from Saturday the 12th into Sunday the 13th, the swell fades back to tiny 1-2ft junk with poor scores. A long gap and then a couple of promising days – check the forecasts, but if you can get out on that Thursday morning, that’s the one.

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.
