The Lowdown
Righto, folks. Rusty here. Let's cut through the noise and get straight to the point for this stretch of coast. We're looking at a pretty grim 16-day window, I'm not gonna sugarcoat it. The pattern is set for dirty, cross-shore winds and lumpy, uninviting surf. The only spot on the radar is Sandtracks, a reef break that's fairly consistent but often crowded. It's an intermediate-level wave, and it's exposed to the swell, needing something from the SSE to really get it going. The water's sitting at 81°, which is pretty normal for this time of year.
The problem is, from now right through to the end of the outlook, the wind is locked in from the ENE and E, blowing straight across the wave. That means the surface is constantly chopped up by a moderate to fresh breeze, creating a real mess. There's some moderate swell energy (around 300-400 units) in the first few days, but the wind is just ruining it. We get a little spike of energy (up to 675) on Monday the 10th of August, with a 5 ft swell from the ENE, but again, a fresh cross-shore kills it. The periods are short, around 8-10 seconds, so it's all windswell, no real power behind it.
Later in the week, from around the 12th of August, the swell energy jumps up a bit more, hitting over 900 units, and the swell direction swings to the S and SSW, which is a better angle for Sandtracks, but the wind stays the same – fresh and cross-shore. The swell height gets up to 6 ft and even 7 ft on the 14th and 15th of August, with periods of 8 seconds, but the wave quality is just poor. It's likely to be a windblown, lumpy mess. The strong breeze does kick in towards the 17th of August, making it even worse. Honestly, for the whole 16 days, there's not a single session that's worth paddling out for. It's a total blank run.
Because of the persistent strong cross-shore wind and the significant swell energy, this setup actually looks more interesting for kite surfing than paddle surfing. The conditions are just not there for a clean wave.
Rusty.

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.
