The Lowdown

Righto, let’s have a look at what’s cookin’ for Windang Island over the next couple of weeks.

First up, the water temp is sittin’ about 65°, which is a touch warmer than normal for this time of year – nothing wild, but a nice little bonus.

The next week or so is a bit of a mixed bag. We kick off on Saturday the 18th with some small weak energy (113) and a tiny 2ft easterly windswell, but the cross-on breeze is gonna make it messy. Not worth paddlin’ out for. Sunday the 19th sees a solid jump in size to 6ft from the ENE, with a long 11-second period – that’s proper groundswell energy – and the combined energy is cranked up to 834 – solid stuff. But the wind is cross or cross-on, so it’s not gonna be clean. The score says marginal, and I’d agree.

The real window opens Monday morning the 20th. We’ve got 5ft of ENE groundswell (period 11 seconds) with a light NNW cross-off breeze. The energy is still strong at 713, and the conditions are clean. That’s the standout for the first week. Windang Island is a reef and point setup, so that long-period swell will wrap in nicely and offer some proper lines. The offshore wind will keep the faces smooth. It’s not the biggest, but it’s the best combo of size, power, and clean conditions in the early part of the forecast. Just be aware that crowds are possible here.

Tuesday the 21st drops off a notch to 4ft with a 10-second period, but the morning still has that clean cross-off wind. It’s surfable, but nothin’ special.

Then we hit a bit of a lull mid-week. Wednesday the 22nd has small 3ft or less swell, with offshore wind but very ordinary waves. Thursday the 23rd comes back up to 6ft from the south, but the wind is howling from the SSW and S, making it messy.

Now, here’s the real gem. Friday morning the 24th of July. The swell holds at 6ft from the south, period 10 seconds, and the energy is a solid 668. But the magic is the wind: glassy. Dead flat calm. That’s a rare treat for a reef and point break. This is the best on offer across the whole outlook. Clean, lined-up, and powerful enough for a good session. The swell direction from the south is a good match for the optimum SE direction, so it’ll wrap in well.

After that, it fades. Saturday the 25th is small and glassy in the morning, but only 3ft. From there, the swell drops into the doldrums for most of the next week. From Sunday the 26th through to Wednesday the 29th, we’re looking at weak, small waves – mostly under 3ft – with poor conditions. The energy values are mostly in the double digits, just a dribble. Thursday the 30th has a weird spike: a 1ft swell with a wild 18-second period (energy 246) – that’s a very long period groundswell, but it’s tiny and the wind is cross. Not worth gettin’ excited about. Later that same day, a 6ft short-period (7 seconds) SE windswell pops up, but it’s cross-shore and choppy.

The first two days of August (Saturday and Sunday) are a write-off – rain, strong wind, and poor conditions. The very last session on Sunday afternoon the 2nd shows a glimmer with 4ft clean waves and a light cross-off breeze, but the energy is only 207 and the swell is from the east with a short 8-second period. It’s a maybe, but not a standout.

So, bottom line: if you’re lookin’ for the best, target Monday morning the 20th for that clean 5ft ENE groundswell, or Friday morning the 24th for the glassy 6ft south swell. That Friday is the pick of the lot.

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.
