The Lowdown

G’day, Rusty here. Look, I’ll be straight with you – this 16-day window for Windang Island is a tough one. We’re looking at a long stretch of mostly small, weak, and wind-affected surf, with only a couple of short windows that might get the heart rate up. The early part of the forecast is pretty grim, with a run of poor surf conditions from Thursday 20 August right through to the end of the month. It’s not until the tail end of the first week that we get a glimpse of something worth paddling for.

The standout moment in this whole outlook is the morning of Wednesday 26 August. Overnight, a solid south swell builds in, and we’re looking at a clean 7 ft of south swell (moderate wave energy at 727). The wind is offshore from the southwest, so it’ll be groomed and clean. This is a proper, powerful swell for a reef and point break like Windang Island, but at this size, it’s for experienced surfers only – beginners will be in over their heads. The wave period is a short 8 seconds, so it’ll be a bit lumpy and less organised than a groundswell, but the offshore wind will help. It’s a fleeting window of quality, so if you’re keen, you’ll want to be on it early.

Following that, the Wednesday afternoon holds similar size at 7 ft from the south (strong energy at 1171), still with a clean offshore wind, but it’s a bit raw and will also be for experts only. After that, the swell drops off quickly, and we’re back into ordinary conditions for the rest of the week and into the start of September, with small, messy waves and cross-onshore winds.

Water temp is around 65°F, which is about normal for this time of year, so no surprises there.

Later in the run, Saturday 29 August morning sees a bump in swell to 6 ft from the northeast (moderate energy at 399) with a clean offshore wind, but it’s not big enough to call a standout, and the period is short. After that, the forecast gets pretty bleak again, with small, weak surf and mostly onshore or cross winds, right through to Friday 4 September. Nothing really worth chasing in that second week – it’s mostly a write-off for decent waves.

So, to sum it up: the best bet is Wednesday 26 August morning, but it’s a short-lived, expert-only session. If you can be patient, keep an eye on the forecasts – things can change.

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.
