The Lowdown
Alright, Rusty here again. Let’s run through it in feet and Fahrenheit for those who think that way.
We’re looking at a slowish start around Windang Island. The first few days have either tiny waves or messy wind. Don’t bother until later. The good stuff starts to pop on Tuesday the 25th and then again late in the month and into early September.
Wind is the key – we get some beautiful glassy or offshore spells, especially Thursday the 27th morning and Friday the 28th morning. Water temp is about average for the time of year, around 65°, nothing unusual.
Here’s the rundown. Friday the 21st: morning is clean but just a 3ft ENE swell with a short 7-second period and weak energy (59). That afternoon goes glassy, but it’s a tiny 3ft NE swell – surfable but nothing to write home about. Saturday the 22nd is a dud – 1.0ft junk.
Sunday the 23rd has more size, 4ft from the S in the morning, but the wind is cross-shore. Energy is moderate (221), but the quality is poor. Monday the 24th is a washout with strong cross-onshore wind.
First real standout: Tuesday the 25th morning. Clean 4ft NE swell with a light cross-offshore breeze from the N, and solid energy (302). That’s a good window. The afternoon goes south with rain and cross-shore wind.
Wednesday the 26th is average. Then Thursday the 27th morning – this is the gem. Glassy as it gets, a clean 4ft S swell with 9-second period, energy at 305. Clean and fun. Friday the 28th morning is also glassy with a 4ft S swell (300 energy) – another top pick.
The weekend of the 29th and 30th turns ugly with strong wind and small surf. There’s a long dry spell from the 30th of August through the 2nd of September – just flat, so leave the stick at home.
We get a glimmer on Thursday the 3rd of September: a 3ft S swell with moderate energy (206), but the wind is light and cross-shore – marginal. The next real winner is Saturday the 5th of September morning: glassy, a 4ft SSE swell, 8-second period, and energy at 306. That’s a nice clean session to wrap things up.
So the best calls are Tuesday the 25th morning, Thursday the 27th morning, Friday the 28th morning, and that Saturday the 5th of September morning. Most waves are between 3ft and 4ft, good for a range of surfers. When that wind goes glassy or offshore, the reef and point setup here will deliver.
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.
