The Lowdown

Alright folks, Rusty here, and I've been staring at the charts for our local patch. Let's get into it.

The short-term looks a bit flat and average, but there's a real change-up coming in the second week. We’ve got a solid window opening up around the 22nd, and a big, clean pulse on the 27th could be the real standout of the whole period. Hang tight, it's a bit of a waiting game.

Right now, the water is sitting at about 64° – that's pretty much bang on average for this time of year, so no surprises there.

Let's start with Windang Island. It's a reef and point setup, exposed to the south-east, which is its sweet spot. Honestly, through to the 22nd, the surf is underwhelming. We've got a bit of fun-size swell on the 13th, with a 4 ft S swell and a light cross-offshore breeze cleaning things up nicely, but the energy is pretty weak (255). It's surfable, but not a standout. The 15th sees a bit more size with a 5 ft S swell, but a moderate 12 mph SSW breeze is making it a bit wobbly.

We then hit a real lull. From the 17th right through to the 21st, there's a big gap of several days with very little to recommend. You'll find a few glassy mornings on the 18th and 19th, but with tiny waves (2 ft to 3 ft) and very weak energy (120 to 108), it's a longboard or a day off, really.

Now, things start to look up on the 22nd. The 22nd of August Saturday afternoon is the first real flash of hope. We've got a 5 ft ENE swell, and the wind is a clean offshore from the W at 9 mph. The wave energy jumps up to a solid 593, and the forecast is for very good conditions. This is the one to aim for if you can get a late session in.

That trend continues into the 23rd with a 4 ft ENE swell and a 9 mph NW cross-offshore wind, keeping it clean. Good, but not a classic.

The real highlight, and the one I'm getting excited about, is the 27th of August Thursday morning. This is a proper pulse. We're looking at a 7 ft S swell, with a clean 15 mph offshore wind from the W. The wave energy is huge, sitting at 1009, which is very strong. The period is 10 seconds, which is solid. This is the kind of day that Windang Island was built for. The water will be clean, there's real power, and it's pointing straight in. This is expert territory at that size, but if you're confident, this is the best session of the forecast period, by a long shot. The afternoon gets a bit questionable for tide, but the morning is the call.

After that, the 28th still has some size at 6 ft from the SSE, but the wind is a bit more on it, making it tricky.

So, to sum it up: the first week is a grind. Get your board ready for the 22nd for a fun afternoon session, and mark the 27th of August Thursday morning in your calendar. That's the day.

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.
