The Lowdown
G’day, I’m Rusty, and I’ve been staring at the charts for your area. I gotta be straight with you – the outlook for the next 16 days is a tough one. There’s no real standout session, and we’re looking at a long stretch of slop.
The only spot on the radar is Sandtracks, a reef break that’s exposed to the swell. It’s a fairly consistent spot, but it’s not doing us any favours. The water temp is about average for the time of year.
We kick off on Saturday, 8 August, with a tiny 2ft swell from the SSW, but with a 19 mph cross-shore wind from the ENE, it’s just lumpy and messy. The combined energy is a weak 510, and it’s a write-off. This poor pattern sticks around for days. The swell stays below 4ft through to Tuesday, 11 August, with that same pesky cross-shore wind. The wave energy is moderate at best, but the wind just ruins it.
Wednesday, 12 August, shows a glimmer of hope with a 3ft S swell, with a long 18-second period, but again, the wind is a fresh cross-shore. The combined energy jumps to 1032, which is moderate, but the surf is still marginal. Not worth a paddle.
From Thursday, 13 August, things get worse. The swell builds, but the wind picks up to 22-28 mph, turning the ocean into a washing machine. By Saturday, 15 August, we’re looking at a solid 11ft E swell, with strong wave energy (2562), but the wind is a strong cross-shore, creating messy, dangerous conditions. By Sunday, 16 August, the swell hits 11ft from the SSE, with a massive 5736 combined energy, but with the same strong cross-shore, this is strictly for experts, and even then, it’s a battle. These bigger swells (over 8ft) are only for experienced surfers, and with the wind, it’s a no-go.
The final week from 18 August onwards drops off again, with waves under 3ft and ongoing cross-shore winds. The energy drops right back down to weak levels.
In short, we have a gap of about 16 days with no real recommendation. The conditions are consistently poor due to the wind. It’s a blank run, but for this area, that’s normal. Forecasts can change. Keep an eye on it, but for now, leave the board in the shed.
Rusty.

Information about the Sandtracks Surf forecast
The above surf forecast table for Sandtracks provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Sandtracks can be found by selecting the local surf guide option on the grey menu. Our Sandtracks 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 (Sandtracks) 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 Sandtracks 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.
