The Lowdown
Alright folks, Rusty here. Let’s get into it for Disappearing Sands. This place is an inconsistent, beginner-friendly, exposed spot that only really works with a solid WNW swell pushing in.
The first half of the 16-day window has some decent size, but the quality is a bit of a mixed bag. We’ve got a run of swell from Saturday the 5th through to Tuesday the 8th, with wave heights holding around 5 ft to 7 ft from the SSW and then swinging to the W. The combined energy is moderate to strong, hitting up to 2068, so there’s plenty of grunt in the water. The period is a nice 11 to 13 seconds, which is solid groundswell – good for shape and power. The problem is the wind. It’s mostly onshore or cross-on from the west, so it’ll be bumpy and not the cleanest. The best of that early run looks like Sunday afternoon (6th) and Monday afternoon (7th). On Sunday afternoon the swell is 5 ft from the SW with a 12-second period, and the wind goes light cross-on from the WNW at 3 mph, making it a bit more workable. Monday afternoon sees the swell peak at 7 ft from the WSW with a 13-second period, and again a light WNW cross-on at 3 mph. That’s the biggest and best-shaped wave of the early window, though it’s still a little onshore. That 7 ft swell is getting into the size where it’s probably too much for beginners, but for the rest of you, it’s the pick of the first week.
Then we hit a real dry spell. From Wednesday the 9th all the way through to Tuesday the 15th, the swell fades to almost nothing – 1 ft to 2 ft for most of that stretch. The combined energy drops to under 300, which is weak. The wind is light and variable, but there’s simply no wave to ride. Wednesday the 16th sees a slight bump back to 3 ft from the SW, but it’s still weak and marginal.
Now, here’s the standout. The real light at the end of the tunnel is Thursday the 17th of September. The afternoon session at Disappearing Sands is looking promising. The swell is still only 2 ft from the SW, but the period stretches to 16 seconds – that’s proper long-period groundswell. The combined energy jumps to 514 (moderate), and more importantly, the wind is forecast to be glassy. Glassy. That’s a rare treat here. Those long-period swells can break a bit straight on a beach break, but Disappearing Sands is exposed to the WNW, so if the swell direction is right, it could link up nicely. The wave height is small, so it’s perfect for the beginners this spot is known for, and with no wind, it’ll be clean as a whistle. The crowds are listed as “sometimes,” so you might have a few others out, but with such a small forecast, it won’t be packed.
The water temperature anomaly is about average for the time of year, so nothing unusual to report there.
Signing off, 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.
