The Lowdown
Alright folks, Rusty here. Let’s talk about what we’ve got coming up at Disappearing Sands. This is an exposed beach break that’s best for beginners, but it’s notoriously inconsistent, so we need to be patient.
Right now, on Sunday the 23rd of August, we’ve got our first real chance. It’s tiny, just 2ft of swell from the SSW, but check out this period – a solid 15 seconds. That’s proper groundswell energy, and the combined energy reading (264) is a decent moderate push. The best part? The wind is glassy, absolutely dead calm, so the surface will be like a mirror. The water is sitting at a balmy 82°, which is a touch warmer than normal for this time of year. For a beginner spot that rarely lines up, this Sunday afternoon is the standout of the whole outlook – clean, small, and forgiving.
Monday the 24th keeps the small, clean vibe going in the afternoon with another glassy window, though the swell stays at 2ft from the SSW. The morning on Monday has a light offshore breeze, but we get a marginal tide comment, so keep an eye on that.
Now, we hit a big dry spell. From Tuesday the 25th all the way through to the end of August, it’s mostly poor. There’s a heap of days where the winds go cross or cross-onshore, the swell drops out, and the conditions are just messy. You get days like Sunday the 30th with some energy (130 energy), but it’s cross-onshore and small. That’s a long stretch of nothing much.
The next real flicker of life comes on Tuesday, September 1st. We see a pulse of 3ft from the SSW with a very long 18-second period. That’s a lot of energy (569 energy) for this break, but the forecast flags it as marginal due to questionable tide conditions. Even so, that long-period groundswell could wrap in and offer some surprisingly fun shapes if the tide works out.
We then go quiet again until Sunday, September 6th, where another SSW groundswell shows up (3-3ft, 17-second period) with moderate energy in the 440-508 range. The winds on the 6th are still a bit cross-onshore, so not perfect.
The very last day in the window, Monday the 7th of September, is our second real highlight. Again we see a 3ft SSW groundswell, 16-second period, with strong combined energy (477). And just like the start of the run, the wind goes glassy. That morning session looks absolutely beautiful for a beginner wave. The afternoon stiffens up, but that morning window is the one to circle.
So, to keep it simple: your best bets are Sunday the 23rd of August afternoon and Monday the 7th of September morning. Both have glassy conditions and clean, long-period groundswell. Everything else is a gamble or a write-off. For a spot that’s this inconsistent, this is about as good as a promise gets – but don’t blink, or you’ll miss it.
Rusty.

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.
