The Lowdown

Righto, grab a cuppa, let's have a look at what's on the cards for the next few weeks.

The window starts quiet, but there's a proper pulse of southern hemi groundswell building for the second week that’s got our best break, Windang Island, looking really interesting. It’s a solid reef and point setup, fairly consistent, and it loves a solid SE swell, so this run has plenty of potential. Just keep in mind it’s an advanced wave, so this isn't one for the groms or the weekend warriors.

The first few days are small and uninspiring. Friday the 7th is a write-off with a tiny 2ft SSE swell and a light offshore in the morning, but the SE cross-on wrecking it by the arvo. Saturday the 8th shows a glimmer of hope: a glassy 2ft S swell on the morning, with a period of 8 seconds. It’s tiny, but it’s clean. That’s about it for the first week—everything else is either onshore, choppy, or just too small to bother with. There’s a block of nothing worth chasing from Saturday arvo right through to the end of the second week.

Now, hold onto your board. The real action kicks off on Thursday the 13th, when a solid 6ft S swell rolls in with a 10-second period and a combined energy of 686 (moderate wave energy). It’s clean with a cross-off offshore, but the wind goes cross-shore in the arvo. That’s a warm-up. Friday the 14th is the morning you want to circle. The swell drops slightly to 6ft from the SSE, but the wind is a light cross-off, and the conditions are described as "very good." This is the standout. The 10-second period means it’s a proper groundswell with good shape, and the energy is still high at 632 (moderate wave energy). But for a point reef like Windang Island, that long period makes for some beautifully lined-up walls. The morning is the pick; the arvo gets chopped by a cross-onshore.

The following Saturday the 15th still has some 4ft SSE swell, but it’s not as clean. After that, the swell drops right off into the third week, with nothing but tiny, poor conditions through to the 22nd. There’s a late pulse on Friday the 21st with a 6ft S swell, but it’s got a short 7-second period and onshore winds, so it’s messy. The 22nd has a 7ft S swell with a cross-shore wind, but it’s borderline for experts and the quality is marginal.

The water temp is about average for this time of year, so no worries there. If you are a solid surfer, the absolute best on offer is Friday morning the 14th at Windang Island. The 6ft SSE swell, light cross-off wind, and clean conditions will be a real treat. The 13th is a solid backup if you can handle the bumpier arvo conditions. Everything else is a pass.

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.
