The Lowdown

Righto, let’s have a look at what’s shaping up for Windang Island. This is a reef and point set-up, exposed to the swell, and it’s a fairly consistent spot that doesn’t need much to get going. The water temp is sitting at 65°, which is about 2° warmer than the long-term average for this time of year—so you’re in for a nice, slightly warmer-than-usual paddle.

The first few days are a bit of a write-off, I won’t lie. From Tuesday the 4th right through to the start of the second week, there’s just not enough push in the water to get excited about. We’re talking tiny dribbles of 0.7ft to 1.0ft swell with weak energy (18 to 24). The wind is offshore or glassy at times, which is a tease, but the swell is basically non-existent. That run of flat spells lasts a solid week before anything worth paddling out for shows up.

The first real glimmer comes on Thursday morning the 13th. We’ve got a 4ft S swell with a short period of 8 seconds, but the wind is a light cross-off from the WSW, and it’s clean. The energy is moderate (247). It’s surfable, but it’s not the standout.

The standout is Thursday afternoon on the 13th. This is the one. A 8ft S swell, period jumping to 11 seconds, and the wind drops to glassy from the NE. The energy here is strong (1374). This is excellent surf for experienced surfers—clean, powerful, and those long gaps between sets will make it easier to get out the back. The water is clear, the sun’s out, and it’s going to be a session you remember. The swell direction is directly from the south, which is bang on the optimum for this spot. Crowds are possible here, so get in early.

Friday the 14th stays big but gets a bit tricky. Morning is 8ft S swell with a 10-second period, but the wind is light cross from the south, and the energy is very strong (2049). This is expert-only territory; too big for most. The afternoon drops to 7ft, but the wind swings around to a cross-shore, keeping it a bit lumpy. Same story Saturday morning the 15th—6ft from the south, glassy conditions, but the period is short (7 seconds), so it’s a bit dumpy. Still, a good option for the confident crew.

After that, the swell fades off again through the middle of the second week, with a few smaller, wind-affected days. The final highlight looks like Wednesday morning the 19th: 6ft SE swell, 9-second period, clean with a light cross-off from the NW. The energy is solid (731). It’s a good, clean option to wrap up the window.

So, bottom line: if you’re keen, point your board at the 13th of August. That Thursday afternoon is the pick of the pack. The rest of the window is either flat or too gnarly for the average punter.

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.
