The Lowdown

G'day, Rusty here. We’ve got a bit of a slow start ahead for Windang Island, but there’s some real gold waiting if you're patient. The early part of the week is mostly small and ordinary, but the second half of the forecast period shapes up nicely, with a couple of standout days that will make the wait worthwhile.

The first bit of half-decent surf rolls in on Monday morning, 3rd August. It’s clean, with a 3ft SE swell and a 10-second period, but the wave energy is only moderate (198). The water temp is sitting right around average for this time of year at 65°, with a breeze from the NNW making it a cross-off. It’s surfable, but pretty ordinary – not worth rushing out for.

Tuesday and Wednesday are basically a write-off. Swell drops right off to 0.7ft-1ft, with energy readings in the teens and twenties. The wind is offshore and clean, but there’s just no wave to ride. Thursday morning sees a tiny 2ft S swell with a short 8-second period and light offshore wind, but it’s still a poor surf call.

Friday the 7th is the first real glimmer. A glassy morning with 3ft S swell, 9-second period, and a moderate energy reading of 125. The wind is dead calm and glassy – perfect conditions for a longboard. The waves are small, but clean as a whistle.

Saturday morning the 8th is also glassy, with a 2ft S swell at 8 seconds and 107 energy. Again, tiny but clean. Afternoon turns choppy as the NE wind picks up.

The middle of the week brings cleaner conditions but still tiny waves. The 11th and 12th have some glassy or light offshore mornings with 1ft-2ft swells, but nothing to get excited about.

Now, the real standout pops up on Friday morning, 14th August. This is the one to circle. A 6ft S swell with a 9-second period, and the wind is dead calm – glassy perfection. The energy is very strong (517). Conditions are expected to be very good. This is peak for the period, and it’s early in the day. The afternoon is a no-go because the swell jumps to 10ft with a 12-second period, but an onshore wind makes it messy and only for the experts.

Saturday the 15th carries over that energy with a 6ft S swell (10 seconds, 583 energy), but it’s a morning call with a light cross-shore breeze. Still a solid option, but not as clean as Friday.

Sunday the 16th and Monday the 17th mornings both have glassy conditions and 4ft SE swells with 10-second periods, delivering moderate to strong energy (229 and 318). These are clean, fun, and reliable – a great way to wrap up the run.

The very end of the outlook, on the 18th, drops back to small and uninspiring.

So, to sum it up: the best on offer is Friday morning, 14th August at Windang Island. Glassy conditions, a solid 6ft S swell, and strong energy. If you miss that, Saturday morning 15th and Monday morning 17th are also worth your time. Everything else is either too small or too messy.

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.

Windang Island is 7 km (4 miles) from the city of Port Kembla. If you plan a holiday in Illawarra, look for hotels and other accommodation in Port Kembla. Port Kembla has rooms for a wide range of budgets as well as car hire and transport links.
