The Lowdown
Mate, let’s have a look at what’s coming up for Windang Island. This is a solid reef and point setup that needs a south-east swell to really light up, and we’ve got a bit of a mixed bag over the next couple of weeks. The water’s sitting at 65°F – that’s about 2°F warmer than usual for this time of year, so the winter suits are staying on the hanger for now.
The first real chance to get wet kicks off on Friday afternoon, July 31st. There’s a 7ft S swell running with a 9-second period, but the wind is cross from the south at 9 mph. The combined energy is pumping at 1206 (strong energy), but the wind is putting a bit of chop on the face. It’s surfable, the quality is okay, but the wind isn’t doing you any favours. Friday morning was a bust, so this is the first window.
Saturday morning, August 1st, drops to 5ft from the SSE, still a 9-second period, but the wind is light cross from the south at 6 mph. The energy drops to 356 (moderate). It’s a bit ordinary, but the wind is manageable. Saturday afternoon gets glassy with a NE wind at 3 mph – that’s a major positive. The swell is 5ft from the SSE, 9 seconds, and the energy is 316 (moderate). That glassy window will be clean, but it’s not the biggest.
Sunday morning, August 2nd, is the standout. The swell is 5ft from the SE, but the period jumps to 12 seconds – that’s a proper groundswell. The wind is cross-off from the north at 9 mph, so it’s clean. The combined energy hits 666 (strong energy). This is the best on offer in the whole outlook. The longer period means better shaped waves, more push, and longer lulls between sets, which makes paddling out a bit easier. This is a point and reef break, so that long-period swell will wrap in nicely. The crowd factor is “sometimes” here, so you might have a few out, but it’s not a zoo.
Sunday afternoon gets messy with a strong cross-on from the NE at 16 mph, so get out in the morning.
Monday, August 3rd, drops to 3ft, and from there it’s a long, slow fade. There’s a small window on Wednesday morning, August 5th, with a 3ft S swell, 10-second period, and offshore wind from the west at 6 mph. The energy is 210 (moderate). It’s clean, but it’s small. That’s a surfable option if you’re desperate.
Thursday morning, August 6th, gives us a glassy start with a 5ft S swell, but the period is only 8 seconds – short period, so the waves will be a bit jumbled. The energy is 286 (moderate). It’s clean, but not special.
Friday morning, August 7th, is glassy again – zero wind – with a 5ft SSE swell, 9-second period, and energy at 401 (strong). That’s clean and a touch bigger, but the short period keeps it from being a standout. It’s a good session, but not the best of the run.
From Saturday, August 8th, through to the end of the outlook on August 15th, it’s mostly small, weak, and messy. There are long gaps with no real recommendations. The swell drops to under 3ft for days on end, and the wind is often onshore or strong offshore that makes it hard to paddle into the tiny waves. The combined energy mostly sits in the weak range (under 100) for the second week. There’s a couple of clean offshore mornings, like Monday August 10th with a strong 25 mph offshore, but the swell is only 1ft, so it’s not worth suiting up for anything other than a flat-water paddle.
So, the call is: Sunday morning, August 2nd is the clear winner. Get out early for clean 5ft SE groundswell with a 12-second period. That’s your best chance at a proper wave. The rest of the run is either small, short-period, or wind-affected. Don’t hold your breath for the second week – it’s going to be a long flat spell.

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.
