The Lowdown

G’day, Rusty here. Windang Island is our only game in town for this forecast, a reef and point setup that needs the right conditions to fire. The next two weeks have some moments, but there are plenty of average days to wade through too. The water temp is sitting about average for this time of year, nothing wild to report.

The first real surf worth paddling out for lands on Thursday the 27th of August. Morning’s the pick with glassy conditions, a 4ft swell from the south at 10 seconds, and combined energy sitting at a moderate 364. That’s clean, lined up, and easy to get into. Friday the 28th morning is a very close second with a 4ft south swell at 11 seconds and a light offshore cross-off breeze from the southwest – energy’s bumped up a notch to 458, the best we’ll see all week.

The rest of that opening week is a bit of a mixed bag. Tuesday the 25th has a brief pulse of 5ft from the northeast on the arvo, but with a short period and strong cross-shore wind, it’ll be messy. Wednesday the 26th morning cleans up with a light offshore cross-off from the south-southwest and 3ft from the east-northeast, but that’s a marginal one. Saturday the 29th and Sunday the 30th are scratchy.

Heading into the first of September, conditions improve. Tuesday the 1st of September morning and afternoon both see clean, gentle offshore winds out of the west-northwest, with a 3ft south-southeast swell at 12 seconds. Not big, but clean and lined up with 283 energy in the morning. That stretch of good conditions holds through Wednesday the 2nd of September morning with a tiny 2ft south swell at 12 seconds and a light offshore – nothing to get too excited about but it’s surfable.

A gap of a few days follows, with only ordinary sessions until Friday the 4th of September morning, when a light cross-off from the south-southwest meets a 2ft south swell at 12 seconds for a clean, easy paddle. Energy’s at 212 – alright but not a standout.

The second week winds down. Sunday the 6th of September has clean offshore winds from the west-northwest and a 3ft south swell at 10 seconds – small but tidy. Monday the 7th of September morning is glassy, with a tiny 2ft south swell at 10 seconds and energy of 123. It’s the end of the run, a quiet finish.

For the standout, I’m calling Thursday the 27th of August morning – that glassy 4ft south swell with a moderate 364 energy is the cleanest, most lined-up session we’ve got. Friday the 28th morning is a very close second. For the long-range, Tuesday the 1st of September is promising but less certain – still clean, but smaller.

Crowds at Windang Island? They can happen sometimes, so you might not have it all to yourself on those good days.

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.
