The Lowdown
G’day, Rusty here. Let’s have a yarn about Sandtracks. To be straight with you, this 16-day window is a bit of a grind. There’s nothing on offer at the start, so we’re looking at a dry spell before something finally pops up.
The first chance we get to paddle out is on Friday afternoon the 4th of September, but honestly, it’s only a marginal call. You’ll find 4 ft of swell from the ENE, with a period of 9 seconds, and the wind is cross-offshore from the NE at 16 mph. It’s clean, but the wave energy is only moderate at 600, so it’s not exactly a pump. Sandtracks is a reef break, and it’s fairly consistent, though crowds are often a factor here. The water temperature is about 82°, which feels normal for this time of year with an anomaly of just 1°.
The best on offer, and the true standout, comes on Tuesday the 8th of September in the afternoon. We’ve got 4 ft of swell from the SSW, with a very long period of 15 seconds—that’s groundswell, proper energy. The wind is cross-offshore from the NE at 19 mph, keeping things clean. The combined swell energy is strong at 1061. This is the pick of the bunch: clean, long-period lines that will wrap nicely around the reef. Just bear in mind those long-period swells can be a bit tricky at beach breaks, but Sandtracks being a reef setup should handle it well. This one is worth marking on the calendar.
Then on Wednesday morning the 9th of September, there’s another marginal window with 7 ft from the east, but only 8 seconds period, and a light cross-breeze from the east at 6 mph. The energy is moderate at 899, and it’s clean enough, but it’s nothing special.
After that, we see a few clean but unremarkable days around the 11th of September, with 5 ft from the SSE and S, periods around 10 seconds, and light cross-offshore winds. Crowd potential is there, but the consistency drops off.
So, overall: the best bet is the afternoon of the 8th of September—clean, long-period groundswell with a good direction for the reef. The rest is mostly marginal or poor. Keep your eyes on the charts, because a decent window like that can fire.
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.
