The Lowdown
G'day, I'm Rusty. Let's get into it, mate.
Alright, the next 16 days at Sandtracks are a bit of a mixed bag. We've got some solid swell windows, but the wind is the real story here, and it's not always our mate. The first few days are a write-off, but there is some light at the end of the tunnel.
The first decent chance we get is on the morning of Wednesday, the 9th of September. The wind drops right out, going glassy, and the swell is a clean 3ft from the SSW with a long 14-second period. The combined energy is moderate (456). This is about as clean as it gets for the reef, but it's a small wave. Don't expect a monster, but it'll be a fun, grovelly session. The water temp is about average for the time of year.
Then we skip ahead to Friday the 11th of September. The swell picks up a bit to 5ft from the ENE with a 12-second period, giving moderate energy (1024). The wind is a gentle cross-onshore, so it'll be a bit bumpy, but it's surfable. This is a better size but not as clean as the glassy Wednesday.
Honestly, the standout window is that glassy Wednesday morning, the 9th. It's small, but the conditions are perfect. After that, the biggest and most powerful swell hits around Monday, the 14th of September, and Tuesday, the 15th of September. We're looking at 10ft to 15ft from the E with strong energy (2611 to 5880). The swell period is 11 seconds. This is big, heavy stuff, only for the experienced crew. The wind is a strong cross-shore, so it'll be a lumpy, challenging paddle out. This is expert territory only.
For the rest of the run, the wind is mostly a fresh cross-shore, keeping things lumpy and choppy. So, if you're looking for the best chance of a clean wave, that Wednesday morning is the one to circle. The bigger swell later in the window is for the brave, but conditions won't be perfect.
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.
