The Lowdown
Alright, Rusty here again. Let's break down the same picture in feet and miles.
We’re starting off slow at Windang Island. The first few days have some swell, but the wind is all messed up, so it’s not worth the effort. The real standout has to be that Friday morning, September 11th. It’s not the biggest, but the conditions are going to be perfect. We’ve got a 6 ft swell from the SSE hitting the reef and point, with glassy, dead calm wind. That’s the kind of morning you call in sick for. The water temp is about 64°, which is normal for the season.
The period is 10 seconds, so there’s good shape and energy. The combined energy is moderate (653). That’s the pick of the whole forecast.
After that, it gets messy again. Sunday the 13th has a clean window with a 3 ft south swell and an 11-second period. The wind is light and cross-off, so it’ll be clean, but it’s not going to have the power of that Friday. The energy is lower (267). A fun, small wave, but not a highlight.
Monday the 14th has another glassy start, but the swell drops to 3 ft. The period is a long 11 seconds, so it’ll be lined up and clean, but it’s just small and soft. The energy is low (211). Worth a paddle if you’re local, but don’t drive for it.
Looking ahead to the 15th and 16th, the swell jumps up again, but the wind is howling – 30 km/h (19 mph) cross-shore on Tuesday afternoon. That’s ugly. The swell is over 8 ft, which is expert-only territory, but with that wind, it’s a chaotic mess. The energy is strong (953), but it’s a kite surfer’s day, not a surfer’s.
The 17th has a clean morning with a 5 ft south swell and an 11-second period, and the wind is cross-off. The energy is moderate (646). That’s a decent option if you get out early before the onshore wind ruins it in the afternoon.
So, to wrap it up: the best day of the whole 16 days is that Friday morning, September 11th. Glassy, clean, and the point will be working. Don’t miss it.
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.
