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

We’ve got a solid run of surf on the horizon, but it’s a tale of two halves. The first week or so is pretty average, with a lot of marginal conditions and low energy. The real standout, the one that’s got me talking, is waiting for us in the second week.

Right off the bat, for Tuesday the 7th, we’re looking at a chunky 10ft swell from the SSE with a 10-second period, but it’s pretty raw. The combined swell energy is a meaty 3694 (moderate to strong), but a strong cross-off wind is keeping it from being clean. Tuesday afternoon gets bigger to 12ft, but turns into a messy cross-shore chop. Not the day to get excited.

Wednesday the 8th is cleaner with a solid 8ft swell from the SE, and a bit more manageable, but still not a classic. The energy drops to 1393 (moderate). Thursday and Friday see the swell dropping quickly into the 5ft to 5ft range. Friday morning the 10th is a real tease though – glassy conditions with a light 5ft SE swell (459 energy). It’s surfable, but small. Friday afternoon stays glassy and small. Saturday the 11th is offering up clean 4ft waves with a light offshore breeze (243 energy), ideal for a longboard.

From Sunday the 12th, the swell really backs off. We’ve got a few days of very small, ordinary waves down to 1.0ft by Monday the 13th. The energy drops to just 19 (weak). That run of poor-to-ordinary surf lasts right through to around Thursday the 17th.

Then things get interesting. On Monday the 20th, a new pulse of S swell pushes through. We’re looking at 5ft to 6ft, but the wind is messy, making it a bit of a chop-fest. The energy bumps back up to 715 (moderate). Keep an eye on it, but it’s not the one.

The real deal is Tuesday the 21st of July. The forecast is showing a massive 15ft SSE groundswell with a 12-second period, and a combined energy of 5155 (strong). The text says it might be too big for this break. This is expert territory only. The water temperature feels about average for the time of year. Wednesday the 22nd also looks huge, 12ft from the S with glassy conditions and energy at 3953 (strong). The forecast even calls it excellent for experienced surfers. That Tuesday and Wednesday window is the undeniable peak. If you’ve got the skills, that’s the session to aim for, but it’s a long-range call so stay flexible.

So, the story is: a lot of small, clean but weak surf for the first week, then a big, powerful, and potentially dangerous pulse for the experts in the second week. The rest is for the patient or the longboard crew.

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.
