The Lowdown

G’day, Rusty here, lookin’ at the next couple of weeks for Windang Island. We’ve got a bit of a slow start, but there’s a couple of windows that’ll get the heart pumping. The water’s sittin’ at 65°F, which is a touch warmer than usual for this time of year, so you might get away with a thinner wettie.

We kick off Saturday morning, 18 July, with tiny 2ft S swell, but it’s clean with a light cross-off breeze. The energy’s weak (125), so it’s more of a paddle than a ride. That afternoon goes pear-shaped with a cross-on and only 2ft – best to wait.

Sunday morning, 19 July, sees a bump to 6ft from the ENE, but it’s a messy cross-shore wind and the period is 11 seconds, which is decent. The energy’s moderate (854), but it’s a marginal call. The afternoon stays similar.

Now, Monday morning, 20 July – this is where it gets interesting. Clean 5ft ENE swell with a light cross-off NNW breeze. The period’s a solid 10 seconds, and the energy’s strong (640). That’s a proper session on the cards. The afternoon gets ruined by a 12 mph cross-on, so make it a dawn patrol.

Tuesday morning, 21 July, is glassy with 4ft ENE swell. The wind is dead calm, and the waves are clean. The energy’s moderate (324), but with that glass, it’s a joy. The arvo turns choppy again.

Wednesday, 22 July, has small 3ft ENE swell, but it’s offshore all day out of the west. Clean waves, but tiny. Good for a log or a longboard.

Thursday, 23 July, throws a bit of grunt at us. The morning has 7ft S swell with a short 7-second period, so it’s lumpy. The afternoon jumps to 8ft from the S, solid energy (1206), and it’s clean. That’s getting into expert territory – too big for beginners, but for the crew that know what they’re doing, it’s a proper challenge.

Friday, 24 July, is a standout. The morning has 6ft S swell, 9 seconds, clean as a whistle with a light cross-off. The energy’s strong (601). The afternoon drops to 5ft and goes glassy from the SSE – that’s your best session of the week. Clean, lined up, and no wind.

Saturday, 25 July, starts glassy with 3ft S swell, but the period stretches to 11 seconds, so it’ll have some push. The arvo gets a light onshore, so it’s not as good.

Sunday, 26 July, has 5ft S swell in the morning, clean with a light cross-off. The arvo goes cross-on and choppy again.

The week ahead from Monday, 27 July, to Wednesday, 29 July, sees a pulse of S swell, but it’s a mixed bag. Monday morning is clean with 3ft, Tuesday and Wednesday get stronger but windier, with 5ft to 6ft and fresh breezes. The energy on Wednesday arvo hits 1796, which is very strong, but the cross-shore wind makes it messy.

Thursday, 30 July, has 5ft SSE in the morning, clean, but the arvo goes poor.

Friday, 31 July, drops right off to 1ft SE with a 12-second period – that’s a long, weak groundswell, best for the point or reef here, but it’s tiny.

Saturday, 1 August, has 5ft SE swell in the morning, but it’s a short 5-second period, so it’s weak and messy. The arvo jumps to 10ft from the ESE, but that’s a big, short-period mess – more of a kite session than a paddle.

The real standout is Sunday, 2 August. The morning is glassy, 8ft E swell, 10-second period, and the energy is very strong (1114). That’s a solid, clean swell for experienced surfers. The arvo drops to 7ft with a light onshore, but it’s still got punch.

Best bet: Friday, 24 July morning session, and Sunday, 2 August morning. Mark those in the calendar.

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.
