The Lowdown

Righto, Rusty here. Let’s have a look at the next couple of weeks. It’s gonna be a bit of a slow burn for a while, but there are a couple of proper windows coming up that’ll get the blood pumping.

We start off with a flat, frustrating stretch. From Friday the 7th right through to the 12th, the surf at Windang Island (Illawarra) is tiny and pretty much a write-off. The swell’s weak, mostly under 3ft, and the winds are all over the shop—cross-shore, cross-on, and choppy. There’s a bit of swell on the Sunday and Monday, but it’s messy and short-period. You’d be fighting a losing battle for a half-decent wave. This is a real test of patience; the ocean’s just not cooperating.

Then things get interesting. On Thursday the 13th, the wind swings offshore from the WSW, and a proper pulse of southerly groundswell starts to build. It’s a bit raw at first, reading 8ft, but the energy is kicking in. This is the start of the good stuff.

The standout is Friday morning, the 14th. We’ve got a solid 8ft of SSE swell, with a period of 11 seconds, and the wind is a gentle offshore from the WSW. That’s a classic combo for Windang Island. It’s going to be big, powerful, and clean – this is one for the experienced crew, not beginners, as it’s pushing past that 5ft mark. The conditions should be firing. This is the best of the lot for a proper session.

The afternoon cleans up a bit with a 6ft swell, but that morning window is the pick.

The following Friday, the 21st, is another one to circle. After a week of small, bumpy stuff, we get a long-period ENE groundswell at 6ft. The period is a solid 13 seconds, and the morning is glassy with a light WSW wind. Again, this is a big, clean swell. It’s excellent for experienced surfers, but that long period might make it a bit straight at the beach breaks, but a reef and point setup like Windang Island should handle it well. The swell direction is ENE, which isn't the optimum SE, but the quality of the swell and the clean conditions make it a standout.

The 21st is over a week away, so treat it as promising but not locked in. Still, on paper, it looks like a ripper.

All in all, a slow start, but a couple of proper days to get excited about. The water temp is sitting at 65°, which is about average for this time of year, so the rubber’s still on.

Stay patient, keep and eye on the forecast, and be ready for the 14th and the 21st.

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.
