The Lowdown
G’day, Rusty here. Not gonna lie, this outlook for Sandtracks is a bit of a grind for the most part. We’ve got a long stretch of pretty ordinary conditions before a brief glimmer of something worthwhile right at the tail end.
The water’s sitting at a warm 81°, which is bang on average for this time of year, so no surprises there.
The first real chance for a surf kicks off Friday afternoon the 11th of September. Sandtracks is a reef break that’s fairly consistent and exposed to the swell. We’re looking at a modest 3 ft from the ENE, but it’s coming with a moderate cross-breeze at 12 mph, so it’ll be a bit bumpy. The combined energy is moderate at 552, but the wind’s making it messy. Not worth getting too excited about.
Things drop off hard from Saturday the 12th through to Thursday the 24th of September. For almost two weeks, it’s mostly small, weak, and choppy. Swell heights bounce between 1.0 ft and 6 ft, but the wind is relentless – cross-shore and fresh, often blowing 15–22 mph. A lot of these days are rated as poor or marginal. The energy gets strong on a few days – like Thursday the 17th hitting 1239 – but 6 ft of short-period E swell at 10 seconds under a fresh cross-breeze is just a lumpy, blown-out mess. Even the longer-period SSW swells (15–24 seconds) are getting trashed by the wind. Honestly, this stretch looks more like kiteboarding conditions than quality surfing.
Now, here’s the standout. Friday the 25th of September. The morning is still a bit iffy with 5 ft from the E at 8 seconds and a cross-onshore breeze, but the afternoon... That’s the one. The wind drops to glassy – dead calm at just 3 mph from the SSW – and we get 5 ft of E swell. The period is short at 8 seconds, but with clean, glassy conditions, that small E swell will have a nice shape on the reef. The combined energy is moderate at 632. Crowds are often here, so expect some company, but when it’s this clean, it’s worth it. This is your window.
After that, the weekend of the 26th of September fades back into onshore slop with small SSW swell. The pattern doesn’t hold.
So, bottom line: it’s a long, frustrating wait, but that Friday afternoon glass-off at Sandtracks on the 25th is the real deal. Don’t sleep on it.

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.
