The Lowdown

G'day, Rusty here. Let's get into what's on offer for Windang Island over the next couple of weeks. Honestly, mate, the first week is a write-off for any decent surfing. We're looking at a long, dry spell of poor conditions until we finally get a pulse of serious energy, but even that comes with a big caveat.

Right now, and for the first several days, it’s pretty grim. Friday morning starts with a tiny 4ft S swell, but it's glassy, so you could get a few grovel turns in with your mini-mal. The water is sitting at 64°, which is bang on average for this time of year. But after that, it’s a train of small, weak, and messy waves. The combined wave energy is weak, barely scratching 100 to 200 (189-200 energy) over the weekend and into next week. Winds go onshore, cross-shore, it's just a sloppy, frustrating scene. There's a period of glassy conditions again on Wednesday morning (August 19) with a 4ft ESE swell, but it's short-period, weak energy (198 energy), and the tide might not line up. It's not worth paddling out for anything special. The second half of that week, from the 20th to the 22nd, stays tiny, with 2ft to 4ft swells and mostly onshore or strong offshore winds that just flatten everything out. There's a gap of about 5 or 6 days where you can safely leave the boards at home.

Now, here’s where it gets interesting, but you need to be smart about it. On Sunday, August 23, a proper pulse of swell arrives. We’re talking an 12ft S swell with a nice 10-second period and a massive jump in energy to 4093. The wind looks clean, cross-off from the SSW. That’s a lot of water moving around. This is expert territory, mate—anything over 8ft is not for beginners. This is a point and reef, so it should handle that size well and hold a shape, but it's gonna be powerful and heavy. It's the standout session of the whole forecast window, no question. The following morning (Monday, August 24) drops off dramatically to 3ft, so that window is tight.

Then, hold onto your boardies, because Thursday, August 27, gets absolutely wild. The forecast is showing a massive 18ft S swell with a very long 13-second period and the combined energy goes through the roof at 14424. That’s a big, dangerous ocean. The wind is cross-off from the SW, so it'll be clean, but the forecast file itself says it's too big for this break. This is not a surf day unless you're a tow-in pro. It’ll be a beast out there, huge lines and heavy water. It's more of a spectator event than a surfing session. The leftover swell on Friday and Saturday is still big (10ft to 7ft) but cross-shore winds will chop it up. This break can be crowded at the best of times, so if you’re eyeing that Sunday window, be prepared for a pack.

Overall, the only real standout is the Sunday, August 23 session. For the rest, it's either too small, too messy, or too big to be safe. Keep an eye on that big one on the 27th—it'll be a sight.

Rusty, signing off.

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.
