The Lowdown

G’day, Rusty here, looking at what’s on offer for Windang Island over the next couple of weeks. It’s a bit of a mixed bag, but we’ve got a few windows that’ll get the heart pumping.

Right now, the surf is small and messy. Monday morning has a tiny 2ft S swell with a 10-second period, but the cross wind from the north is making it choppy and marginal. The afternoon gets worse with a stronger northerly blowing, so honestly, don’t bother. Tuesday and Wednesday are still poor, with small waves and onshore or cross winds making a mess of things. The water temp is about average for this time of year, nothing too unusual.

We start to see a little light on Thursday the 27th of August. The morning brings a glassy 4ft swell from the south, 8-second period, and the combined energy is moderate at 311. It’s clean, glassy, and the wind is a flat calm sea breeze. This is a solid pick for a Thursday morning session. Crowds are possible here, so get in early.

Friday the 28th is a step back – smaller, crossing wind, not worth the paddle. Saturday the 29th of August, though, that’s the jewel of the first week. Another glassy morning, with a 4ft SSE swell, 10-second period, and clean conditions. The combined energy is moderate at 254. It’s calm, glassy, and the wind is totally absent. This is the standout for the week. It’s a reef and point setup, so the long period energy will wrap in nicely. Crowds are sometimes around, but it’s worth it.

The next few days after that drop off again – small, windy, and poor. We get a bit of a break in the action until the 4th of September. Friday the 4th of September afternoon finally shows some promise: a 3ft S swell, 11-second period, with clean offshore winds from the west at 16 mph. The combined energy jumps to moderate at 335. It’s offshore and clean, which is a major positive. This is a solid session for the second week.

But the real ripper of the entire forecast is Saturday the 5th of September morning. We’ve got a 2ft SE swell, but the period is a very long 16 seconds – that’s a proper groundswell. The combined energy is strong at 504. The wind is a light offshore from the southwest, making it clean. This is going to be a long-period, powerful swell. Given it’s a reef and point, it’ll handle that long period beautifully, giving you long, lined-up waves. The swell is small, so it’s for all levels, but the energy is significant. This is the one to circle on the calendar. The afternoon gets a bit onshore, so hit it early.

Beyond that, the 6th and 7th of September fall apart with strong onshore winds and tiny surf. Nothing to get excited about.

Overall, your best bets are Thursday the 27th and Saturday the 29th of August, and then the standout is Saturday the 5th of September morning. That last one is the one I’d be most keen on.

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.
