Alright, Rusty here. Let’s get into it.

It’s been a bit slow around here, but there’s a pulse of energy coming through. The water temp is sitting at 66°F, which is a touch warmer than usual for this time of year. The first real window of action kicks off on Monday the 6th with a solid 8ft SSE swell rolling into Windang Island, but the southerly wind is blowing cross-shore at 12 mph, and the energy is high (1232) but a bit messy. It’s surfable, but you’ll be working for it.

Tuesday the 7th is where it starts to look a bit better. The swell pops up to 10ft SSE in the morning, pushing 12ft SE by the afternoon with a period of 11 seconds, building some proper power (3636 and 4837). The wind is cross-offshore from the SSW at 12 mph, keeping the face clean. This is the first standout – punchy, powerful surf, but at 10ft to 12ft, this is strictly for the experienced crew. Beginners, stay out of the water.

Wednesday the 8th is still solid, but the swell drops to 8ft and the wind shifts to cross-off in the morning, then cross in the afternoon. The energy is still moderate but the quality is waning.

By Thursday the 9th, the swell is down to 6ft, and the week looks like it’s fading into background noise through the weekend. There’s a few smaller, cleaner windows on Friday the 10th morning with 6ft SE and a light breeze, but it’s nothing to get excited about.

Now, the big one. If you’re keen on planning ahead, mark Friday the 17th of July. We’re looking at a massive 15ft S swell with a 13-second period, delivering a whopping 9636 combined energy. The wind is light and cross-offshore from the SSW, so it’ll be clean. But I’m telling you now – at that size, this is a serious beast. Only for experts, and even then, it’s a big call. The swell direction at S matches the optimum for this reef and point setup, so it could be a classic, but it’s not for the faint-hearted.

Saturday the 18th morning gives a nice little treat – glassy conditions with a 6ft SSE swell, clean and calm. That’s a quieter, more mellow option for anyone who wants a session without the chaos.

The rest of the second week is mostly small, weak, or blown out. Monday the 13th is flat. Tuesday the 14th picks up a tiny 3ft S swell, but it’s short period and not worth rushing for. The 20th and 21st have some tiny, long-period S and SSE swells, but those are more for the longboarders and the patient.

Crowds at Windang Island can be a thing sometimes, but with this mix of size and conditions, it’ll likely be a mix of the dedicated and the brave.

So, to sum it up: Tuesday the 7th is the first decent call for the advanced crew, and Friday the 17th of July is the big, looming standout – but it’s a monster. Everything else is small or average.

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.
