The Lowdown

Alright, Rusty here. Let’s have a look at what’s coming our way for Windang Island.

Right now, the surf is pretty flat and messy. We’ve got a bit of a wait on our hands. The first decent chance doesn’t show up until Monday morning, the 14th of September. Before that, it’s all small, onshore junk with nothing worth paddling out for.

Monday morning, the 14th is the first glimmer of hope. It’s not a standout, but it’s clean. We’re looking at a 4 ft swell from the NE, but with a short period of 7 seconds, so it won’t have much punch. The combined energy is moderate (296), and with a light cross-offshore breeze, it’ll be tidy. It’s a small, weak day but ridable for a grovel.

The real action kicks off Wednesday the 16th. This is the first big swell of the period, but it’s a tricky one. We’ve got a solid 10 ft to 12 ft swell from the S, with a 10-second period. The energy is very strong (1810-2085). This is expert-only territory; anything over 8 ft is for the crew who know what they’re doing. The wind is strong, 30 km/h from the SSW and S, keeping it clean but with a lumpy cross-chop in the afternoon. The high tide or specific conditions could make or break it. Not for the faint-hearted.

Thursday the 17th morning is your best bet for a standout session. The swell drops to a still-chunky 7 ft from the SSE, period at 9 seconds, with strong energy (800). The wind is light offshore from the SSW at 10 km/h, which will groom the reef and point beautifully. This is going to be clean, powerful, and lined up. For advanced surfers, this is the one to circle. The water temp is sitting at 64°F, which is about average for this time of year, so a spring suit is fine.

Friday the 18th morning offers a smaller, glassy option. A 4 ft SSE swell with moderate energy (278) and glassy conditions – that’s a rare treat. The wind is nothing, dead calm. It’ll be a fun, clean day for the intermediate crowd, but not the power of Thursday.

After that, the window closes. From the 19th right through to the 23rd, we’re looking at tiny waves, under 2 ft most days, with onshore or cross-shore winds. It’s a blank run for nearly a week.

Late in the period, around Wednesday the 24th and Thursday the 25th, another solid pulse shows up. The 24th has a 7 ft swell from the E with a short 8-second period, and clean winds. The 25th morning jumps to a 8 ft ENE swell, also short period (8 seconds), with strong energy (1140). This is a long-range call, so it’s promising but less certain. If it holds, that Thursday morning could be another big, powerful day, but it’s likely going to be a bit raw and wind-affected by the afternoon.

So, the standout is Thursday the 17th morning – big, clean, offshore. The backup is Friday the 18th morning for the glassy, smaller waves. The big stuff mid-week is for experts only.

Stay frothy.
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.
