The Lowdown
Alright, this is Rusty.
Well, folks, it’s a bit of a slow start and a long stretch ahead for this region. We’ve got one break to work with, and it’s a finicky one, so we’re going to be playing a waiting game.
Looking at the full 16-day window, the honest truth is there’s no standout, flat-out brilliant surf on offer. This spot, Disappearing Sands, is an inconsistent little beginner-friendly sandbar. It’s rated as exposed, with the optimum swell direction from the WNW, but we’re mostly seeing some weak, short-period south-west swell for the first week.
We kick off on Monday the 14th with tiny 1ft waves coming from the SW, but with onshore wind making a mess of it – it’s a poor start. The combined swell energy is pretty weak, kicking off around a measly (195). Honestly, not worth paddling out for.
We go through Tuesday the 15th and into Wednesday the 16th, the swell bumps up a touch to 2ft and then 3ft from the SSW. Wednesday afternoon looks like the first real chance to get wet. The wind goes glassy, which is a massive positive for clean conditions. The combined energy climbs a bit (457, moderate), but the waves are still very small. It’s a beginner-level pop-up session, nothing more. For the beginner crowd, this might be your best bet for the whole run.
Then it gets grim. From Thursday the 17th all the way through to Saturday the 26th of September, we’ve got a nasty, long stretch of poor conditions. The swell is tiny and inconsistent, often mixing in with on-shore winds that create choppy, unappealing lines. There is a massive gap with almost no decent offers for over a week. You’ll see a few glassy windows late in the day on the 23rd, 24th, and 25th, but only with 1.0ft to 2ft waves and combined energy often below (200). It’s just too small and weak to get excited over.
Finally, on Saturday the 26th of September, we get another glimmer of hope. The afternoon session shows winds going glassy again and the forecast actually saying "expect good surf conditions." The swell is still only 2ft from the SW, with combined energy at (219, moderate). It’s clean and tiny. For a beginner looking for a gentle, clean push, that’s the call.
The very end of the run, around Monday the 28th and Tuesday the 29th, the swell direction shifts to the WNW – which is the optimum direction for this spot – and the size gets closer to 3ft. The combined energy finally climbs into the strong zone (over 500). But the catch? The wind is onshore or cross-onshore, creating choppy conditions. Swell period is also short (13-14 seconds). It’s a frustrating tease – more energy, better direction, but blown out.
The honest call: There are zero standouts here. The best you can hope for is the glassy window on Wednesday the 16th afternoon or Saturday the 26th afternoon for some tiny, clean beginner waves. For everyone else, this 16-day run is mostly a write-off for this spot. Conditions like this are pretty normal for such an inconsistent break – it takes a very specific, clean window to make it worthwhile.
Keep the glassy windows on your radar, but I wouldn't be blocking out any time for 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.
