G’day, Rusty here, lookin’ at the next couple of weeks at Windang Island. It’s a reef and point setup, and it’s a pretty quiet start with bugger-all surf for the first few days. The water’s sittin’ at 65°, which is a touch warmer than usual for this time of year—nothing crazy, just a bit of a anomaly.

Right, so we’ve got a gap from now until the 15th of July. The surf’s tiny, under 2ft, and even though the wind’s offshore, there’s just no energy. Wednesday the 15th is where things start to get interesting. The swell jumps to 8ft in the morning, comin’ from the south with a period of 10 seconds—that’s a decent groundswell, but the period’s not super long. The combined energy is 972 (moderate), and the wind is cross-offshore from the SSW at 15 mph. It’s clean, but the conditions are rated as marginal, so it’s not the best quality. This swell sticks around Thursday the 16th, but the wind turns more cross-shore and the period drops to 7 seconds, which is short and messy—makes it look more like a kite session than a paddle.

Friday the 17th, the morning looks better. Swell’s 5ft from the east with an 8-second period, energy at 320 (weak), but the wind is a gentle cross-offshore from the SSW at 9 mph, keepin’ it clean. Still, it’s not a standout.

Now, here’s the one to pencil in: Sunday the 19th of July. The morning session is the pick of the whole run. The swell bumps up to 10ft from the east with a period of 11 seconds—that’s a solid groundswell with some real grunt. The combined energy is 2032 (strong), and the wind is a light cross-offshore from the SSW at just 6 mph. Conditions are excellent for experienced surfers—this is not for beginners, it’s well over 8ft. The swell direction (east) doesn’t perfectly match the optimum (SE), but the size and clean conditions make it a ripper morning. The afternoon is still 10ft but with a glassy cross-shore wind, though it’s rated as marginal.

Monday the 20th, the morning is still solid at 7ft and clean with a light NW cross-offshore, energy at 1017 (strong). Good for experienced surfers again. The rest of the week tails off, with Tuesday the 21st and Wednesday the 22nd offering nice, clean 5ft to 6ft waves, but nothing that’ll blow your socks off. The second week settles into small, clean surf with the odd glassy morning, but the swell drops below 3ft by the 25th, and energy’s weak. The period stays around 10–12 seconds, so what’s there is clean and tidy, but it’s small.

Overall, Sunday the 19th is the big day—get out there early for the clean, solid 10ft east swell. Expect crowds at Windang Island, as it’s a spot that can get busy.

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.
