The Lowdown
Alright folks, Rusty here. Let’s talk about what’s cooking at Disappearing Sands.
First thing you need to know: the water is running warm, about 82°F, which is a good degree above the norm for this time of year. Makes the whole session feel a bit more tropical.
Now, the outlook. The next couple of weeks are a real mixed bag for this exposed spot. There’s a long stretch of small, onshore junk to get through, but we do have a couple of standout windows if you’re patient.
The first real chance to get wet comes on Tuesday the 11th. It’s nothing special – a 3ft SSW swell with a solid 14-second period pushing into the beach. The combined energy is moderate (521). The catch is a westerly wind blowing straight onshore, plus rain showers. It’s messy, but the long period means there’s some lully power in the water. For a beginner spot, this is more about getting a feel for the ocean than any kind of quality wave.
We drift into a flat spell. Thursday the 13th afternoon turns glassy calm, but with a tiny 2ft NNE swell on a short 6-second period, the energy is weak (62). It’s surfable, but only just.
The real standout appears on Saturday the 15th. That afternoon, things flip. The wind goes glassy, and a 5ft NNE swell rolls in with a 7-second period. The combined energy jumps to 263 (moderate). This is the biggest swell of the period, and with glassy conditions, it’s going to be clean. The swell direction is coming from the NNE, which isn’t the optimum WNW for the spot, but the size and the clean conditions will open up some fun, crumbly faces. The catch? It’s inconsistent, so you’ll be sitting and waiting. This is the best on offer for the whole forecast.
After that, it’s a long, grim run. There’s a stretch from Sunday the 16th all the way through to Friday the 21st that’s mostly poor, with onshore winds and tiny swell. The energy drops to three-digit and even two-digit values. Not worth paddling out for.
We get a pulse of long-period groundswell towards the end of the window. Monday the 24th sees a 3ft SSW swell with a 17-18 second period, giving moderate energy (432-433). The wind is cross-onshore, so it’s not clean, but that long period will offer some shape. The 25th has a 1.0ft SSW swell with a huge 22-second period, but it’s tiny. Again, it’s marginal.
Honestly, if you want to surf, your best bet is that Saturday afternoon (15th). It’s the only time the size and the wind line up properly. The rest of the period is a waiting game.

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.

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.
