The Lowdown
Alright mate, here’s the rundown on the next couple of weeks.
First off, it’s flat as a tack early on. Nothing worth your time from Wednesday the 29th through to late Thursday the 30th. We’re looking at 0.3ft swell with bugger-all energy (8 to 13). Don’t bother.
Thursday the 30th sees the swell kick up to around 5ft, but it’s short-period south swell at 8 seconds and the wind’s all over the shop – cross in the morning, then cross-onshore in the afternoon. Energy hits 325 then 917, but the conditions are just marginal. Not a good bet.
Now Friday the 31st of July – that’s the one. You’ve got a clean 6ft south swell, period up to 10 seconds, and light cross-offshore wind in the morning (SSW at 6 mph). The lines should be clean. Combined energy is 642 – moderate but solid. Windang Island handles this direction well, and with an offshore wind, it’s going to turn on. Crowds can be a thing here sometimes, so get in early. This is your session.
Saturday the 1st of August is smaller – around 5ft to 6ft, but the wind goes onshore later and the periods drop off. Nothing flash. Sunday the 2nd has a clean morning with a 5ft SE swell, 11-second period, and a cross-off north breeze. That could be a fun one, energy sitting at 701.
From Monday the 3rd it goes quiet again – small, weak, or wind-affected right through to around Wednesday the 12th of August. There’s a little bump on Thursday the 13th of August – about 4ft south swell with fresh offshore wind, but energy is only 312 to 446 and it’s only marginal. Not worth getting excited about.
So for my money, Friday the 31st is the standout. Clean, solid, and the water temp is around 66°F – a touch warmer than usual for this time of year, so you’ll be comfy in a spring suit.

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.
