The Lowdown

Alright folks, Rusty here. Let’s get into it. We’ve got a 16-day window on the cards, and for the first few days, we’ll be working for it. The standout period is going to be around Tuesday the 8th and Thursday the 10th, but we have to get through Monday first.

Monday morning (7th September) kicks off with a bit of a whimper. Windang Island has a 5ft SSE swell, but the period is a short 8 seconds and it’s coming with a light cross-shore breeze. The water temp is sitting at 64°, which is pretty much bang on average for this time of year. The combined energy is weak (311), and honestly, it’s a marginal call. The afternoon gets worse with a strong SSE breeze at 15 mph turning the 5ft swell into complete chop. Leave it.

Tuesday morning (8th September) is where it starts to get interesting. We’ve got a 8ft SSE swell, period bumping up to 9 seconds, and the wind is a clean cross-off from the SSW at 9 mph. The water is clean. The energy jumps to a moderate 756. This is the first real window, but it’s a big swell for beginners. For the experienced crew, it’s worth a paddle. The afternoon drops to 6ft with an onshore wind, so the morning is the only call.

Wednesday morning (9th September) is a write-off. 4ft S swell with a strong 15 mph wind. The energy is weak (216). The afternoon sees a jump to a massive 10ft S swell, but with a 21 mph wind, it’s a total mess. Leave it for the kite surfers.

Thursday morning (10th September) is the real gem of the first week. We’ve got an 8ft S swell with a period of 10 seconds, and the wind is a clean cross-off from the SSW at 15 mph. The water is clean. The energy is very strong (1434). This is a solid, powerful groundswell. It’s a big wave, so only for experts, but if you’ve got the stones, this is the session. The afternoon keeps the 10ft SSE swell but the wind turns cross-shore, so the morning is king.

Friday morning (11th September) is still decent. 7ft SSE swell, 9 seconds, and a light cross-shore breeze. The energy is moderate (745). It’s a step down from Thursday but still fun for the experienced.

After Friday, the week runs out of steam. Saturday (12th) and Sunday (13th) drop off fast, with poor conditions and small swell. There’s a bit of a gap through the middle of the week. Monday (14th) and Tuesday (15th) are tiny, with 2ft and 1.0ft waves, respectively. Not worth a second look.

Wednesday morning (16th September) sees a bit of a pulse again. A 7ft S swell with an 8-second period, and a light cross-shore from the north. The energy is moderate (594). It’s a short period, so it’ll be a bit crumbly, but it’s something to watch.

The real late-bloomer is Tuesday morning (22nd September). A 10ft S swell, 9 seconds, and a light cross-shore from the north. The energy is very strong (1449). This is a big, powerful swell. The wind is light, which is promising, but the afternoon turns onshore and choppy. This is a long-range call, so it’s a promising but less certain standout. If it holds, it’s the second best window in the whole outlook.

Best on offer: Thursday morning (10th) for the big, clean groundswell, and Tuesday morning (22nd) as a promising long-range option.

Remember, the crowds at Windang Island can be likely, so get there early.

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.
