The Lowdown
G’day, Rusty here with the imperial take. This 16-day forecast is a rough one – there’s hardly a decent wave to be found. We’ve got a long, dry spell of poor conditions, and the only glimmer of something rideable is way at the end, and even that’s a maybe.
From Wednesday 15 July through the rest of the month, it’s a mess. The wind is relentless – mostly cross or cross-onshore from the east or east-northeast, blowing 9 to 19 mph, and it’s churning up the surface. The swell is tiny, mostly under 3 ft, with moderate energy in the 200–500 range, but the chop and lumpy conditions ruin any chance of a clean wave.
The one highlight, if you’re desperate, is the afternoon of Saturday 25 July at Sandtracks (a reef break). The swell bumps up to 4 ft from the SSW, with a long period of 18 seconds – that’s proper groundswell. The combined energy hits 1115, which is strong, and the wind swings to cross-offshore from the NE at 16 mph, cleaning it up nicely. It’s the best we’ve got, but it’s still only marginal. Water temp is about average for the time of year, nothing special.
The rest is a washout – days of cross-shore chop and lumpy seas. The morning of Saturday 25 July has a slight chance, but the wind is cross-onshore, so it’s still choppy. The afternoon is your only real window, but don’t expect much. Crowds are often at Sandtracks, so you won’t be alone.
For kite surfers, the strong, consistent cross-shore winds and moderate swell might be more appealing than a paddle. For us surfers, it’s a tough wait. The swell is too small and the wind too messy for most of it. Hang in there – forecasts can turn, but right now, this is a lean stretch.
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.
