Alright crew, Rusty here with the lowdown on Back Strands.
To be straight with you, the first week is a total bust. It’s a long, flat spell. The first whisper of a wave is Thursday afternoon, July 9th, with a tiny 3ft W swell. The water is running about 4° warmer than normal, which is wild, but the conditions are just "ordinary" – not worth getting wet for.
From there, it’s a desert. The wind is trash – cross-on, onshore, gusty – and the swell vanishes. The 10th through the 17th are a total loss. You’ll see a clean little 2-3ft wave on Saturday morning, July 18th, but it’s weak and short-lived.
The second week gets a pulse, but it’s all onshore junk. By Monday, July 20th, we’ve got a 5-6ft WNW swell with some energy, but the wind is straight onshore, making it a washing machine. The 23rd throws a big 5-6ft W swell with a long 13-second period and a ton of energy, but it’s getting smashed by 35 km/h wind. That’s a kite surfer’s day, not a paddle surfer’s.
The one standout, and the only session I’d be planning for, is Friday morning, July 24th. The swell is a solid 4-5ft from the W, with a nice 10-second period and good energy. The wind goes offshore from the SSE, cleaning it right up. It’s a reef break, it’s fairly consistent, and the swell direction is perfect. It’ll be glassy and lined up. Just know that crowds are sometimes a thing here, so get there early.
The afternoon of the 24th gets a strong cross-offshore wind, so that morning window is the one.
Rusty out.

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 Back Strands 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.
