The Lowdown
Alright folks, Rusty here. Let's have a look at what's coming our way.
First up, water temps are sitting at 81°F, which is pretty normal for this time of year, so you won't need the thickest rubber.
Right now, the outlook is a bit of a slow burn. The first week is looking pretty uninspiring. We've got a long stretch from Thursday the 30th of July all the way through to the 8th of August where there's just not much to get excited about. The swell is small, mostly around 1ft to 2ft, and the wind is often cross-on or onshore, messing with what little shape there is. Combined energy is weak, staying under 200 for most of that period. It's a bit of a flat spell, but these things happen.
The real stand-out is shaping up for the 10th of August. Monday afternoon at Disappearing Sands is where it's at. That's when we see a jump in the swell to 4ft from the SSW, with a very long period of 16 seconds. That's proper groundswell. The combined energy is a solid 850, which is a good sign. And the wind is forecast to go glassy, which is a massive plus. That will mean clean, lined-up waves. The long period will mean nice, powerful waves, but at a beach break like this, it might be a bit straight, so look for a bank that's working.
The day before, on the 9th of August, there's a hint of a pulse on Sunday afternoon with 3ft from the SSW and a long period of 18 seconds, but it's not as clean. The 10th is the one to aim for.
After that, the swell hangs around in the 3ft to 3ft range for a few days, but the wind turns cross-on again, so the quality drops off. It doesn't look like it's going to be a classic run, but that Monday afternoon window is a genuine chance for a good session.
This is Rusty, signing off.

Information about the Disappearing Sands Surf forecast
The above surf forecast table for Disappearing Sands provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Disappearing Sands can be found by selecting the local surf guide option on the grey menu. Our Disappearing Sands 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 (Disappearing Sands) 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 Disappearing Sands 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.
