The Lowdown

G’day, Rusty here. Let’s talk about what’s happening at Windang Island—and fair warning, it’s a bit of a mixed bag ahead. We’ve got a real quiet spell to start, with tiny, poor surf hanging around for the first several days. The first hint of anything rideable doesn’t really show until Sunday the 23rd, and even then it’s just ordinary.

Saturday the 22nd is a write-off. The swell is a pathetic 1 ft from the NE, period a short 6 seconds, and the combined energy is barely a whisper at 14. Winds are cross-off in the morning but it’s just not enough. Nothing to get out of bed for.

Sunday morning the 23rd is where we get our first little pulse – 3 ft of S swell, 8-second period, with the combined energy climbing to 178 (moderate). The wind is glassy out of the N, so it’ll look clean and inviting, but the wave comment says “very ordinary conditions.” It’s small, and not much push. You could get a few grovelly ones if you’re keen.

Monday the 24th and Tuesday the 25th are poor. The swell stays small and messy, winds are cross or cross-on, and the energy readings hover around 110–185. Nothing worth planning around.

Wednesday the 26th is clean – cross-off SSW wind at 12 mph, with 3 ft from the ENE, 8-second period. Combined energy 115-152. It’s clean, but still very ordinary. Not a standout.

Now here’s the first real glimmer: Thursday the 27th morning. Swell jumps to 4 ft from the S, 7-second period, and combined energy leaps to 324 (moderate-strong). Wind is cross-off from the SSW at 9 mph, keeping the conditions clean. The wave comment says “expect good surf conditions.” This is the best we’ve got so far. The break is a reef and point, advanced level, and it’s exposed to S swell, which matches the direction nicely. It’s fairly consistent, but the crowds are “sometimes” – so you might have company, but it won’t be a zoo. The water temp is 65°, which is about normal for this time of year.

After that, Friday the 28th through to Monday the 1st of September is a lot of “ordinary” mornings with clean windows (offshore or glassy winds) but the swell really backs off – 3 ft, energy dropping to 139-247. Worth a look if you’re desperate, but not a special session.

Then we hit the second week. Tuesday the 2nd of September is poor – 1 ft ENE swell with a long 10-second period, but only 83 combined energy. The morning is clean but there’s no push.

Wednesday the 3rd of September afternoon is the other standout in the whole period. Swell is 3 ft from the S, 9-second period, with combined energy of 309 (moderate-strong). Wind is offshore at 12 mph from the W – clean, glassy offshore conditions. The wave comment says “expect good surf conditions.” That’s a proper session for the crew who can handle the reef.

Thursday the 4th of September is a step down – 3 ft S swell, 10-second period, energy 208, but cross-shore winds make it a bit choppy. Not terrible, but not the pick.

From Friday the 5th of September onwards, it trails off into small, weak, and messy again – 2 to 4 ft, energy under 100 or low 200s, mostly onshore or cross winds. The final Sunday the 6th of September afternoon has a pulse of 4 ft S swell at 10 seconds and energy 289, but with light cross-on wind, it’s marginal.

So the clear winners are Thursday 27th August morning and Wednesday 3rd September afternoon. Both offer the best balance of size, energy, and clean wind. The rest is a grind of small, ordinary surf. If you’re chasing a wave, your odds are best on those two windows.

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.
