The Lowdown

G’day, it’s Rusty.

Honestly, the next couple of weeks are a real mixed bag for Windang Island. We’ve got a lot of small, ordinary days ahead before things finally wake up. Don’t get too excited about the first week – it’s mostly dribble. The standout, and I mean the real standout, is that Thursday the 27th of August morning session. And then there’s another promising window right at the start of September that could be worth circling.

Let’s break it down. The first few days, from Wednesday the 19th through to Tuesday the 25th, are pretty grim. We’re looking at tiny swell, mostly under 4ft, with light and variable winds that aren't doing us any favors. The energy is weak, with combined readings often in the low double digits up to around 150. A couple of afternoons, like Thursday the 20th and Tuesday the 25th, might have a surfable wave, but it’s nothing to rush out for. The water temp is sitting at 65°, which is about normal for this time of year.

Now, that Wednesday the 26th, the wind swings offshore in the morning but the swell is still small. The real action starts on Thursday the 27th. That morning, the swell jumps to 8ft from the SSE with a 10-second period. The energy reading is massive – 1339 – and with a light SSW offshore wind, it’s going to be clean and powerful. This is solid, expert-only territory. It’s over 8ft, so leave the beginners on the beach. This is the pick of the whole run, no question.

The rest of that week gets a bit messy. Thursday afternoon swings onshore, and Friday the 28th backs off to 5ft but with a clean offshore wind. It’s good, but not in the same league as Thursday morning. The weekend of the 29th and 30th gets lumpy, with fresh cross-shore winds and some bigger, messy swell. Saturday afternoon sees a big 10ft SSW pulse with a 30 km/h cross-shore wind – that’s a washing machine, more interesting for kites than a paddle.

Then we get to the second week. The standout in that stretch is the morning of Tuesday, September 1st. The swell is 5ft from the SE with a long 12-second period. The energy is solid at 733, and the wind is glassy – absolutely dead calm. This is where a longer-period swell shines at a reef and point like Windang Island. It should be lined up and clean. It’s a top pick for sure, but being nine days out, treat it as promising rather than locked in.

After that, things fade out again quickly. The water temp is still around average for the time of year. So, to sum it up: if you’re an experienced surfer, chase the morning of Thursday the 27th. If you want something a little more user-friendly but still clean, keep an eye on that Tuesday the 1st of September morning. The rest is mostly flat or blown out.

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.
