The Lowdown

G'day, I'm Rusty. Let's have a look at what's on the cards for the next couple of weeks.

Overall, it's a pretty tough stretch at Sandtracks (reef). The water temperature is about average for this time of year, so nothing out of the ordinary there. The trouble is, for the first week and a half, we're looking at either next to nothing or conditions that are just plain ugly. A lot of small, weak swell with strong cross-shore winds that'll chop things up. There's a solid run of poor conditions from the very start, Wednesday the 19th of August, with a tiny 2 ft SW swell with a 16-second period. The energy is weak (340). It's not worth paddling out for.

Things don't get any better for a while. The wind is relentless, mostly from the ENE and fresh to strong, keeping the surface lumpy and messy. The swell stays small until the 23rd of August, when it pushes up to 5 ft, but it's a short-period 7-second wind swell, and the wind is still howling. That's a kitesurfing setup if I've ever seen one, not a paddle surf. This continues right through to the end of the month. There's a long gap here with no decent surf on offer.

Now, the real standout is way out in the distance. On the 1st of September, things start to get interesting. We've got a proper jump in the combined swell energy, reading 1924, which is strong. The swell is from the ENE at 7 ft, with a period of 11 seconds early on, and it's building. The wind is still cross-shore from the ENE, but it's a moderate breeze, so the conditions are marginal. The 2nd of September sees the biggest swell of the whole forecast: a 8 ft E swell with a 13-second period, and the energy is very strong (2393). The wind is cross-offshore from the NE at 25 mph, which is actually cleaning things up. This is the standout window. It's a solid, powerful groundswell, but it's a big one. Over 8 ft, this is experts-only territory, and the long period might make it break a bit too straight on the beach. But for the crew who know what they're doing, this is the best bet by far.

The 3rd of September still has some size, but the wind swings back to a near gale from the ENE, and the quality drops right off.

So, my pick is to wait it out. Forget the first week and a half. The window to circle is the 1st and 2nd of September. It's a bit of a long-range call, so keep an eye on the models, but that's where the juice is.

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.
