The Lowdown
Alright, folks, Rusty here. Let’s cut through the data and talk about what we’re actually going to ride for the next couple of weeks. It’s patchy, I won’t lie to you.
We open the window on Friday afternoon, the 14th. There’s a tiny 3ft wave from the north, but it’s got a short hitch to it, only 6 seconds. The water’s sitting at 82°, which is a bit warmer than the long-term average for this time of year. But there’s just no punch in it, weak energy. It’s glassy, which is nice, but the waves will be soft and unremarkable. Just a teaser, really.
Saturday the 15th is the one to make the most of early. The swell picks up to 5ft from the NNE, and the energy gets into a moderate range. We’ve got a light cross-offshore breeze, so the faces should be clean and lined up. It’s not huge, but it’s the most rideable surf we’ll see in the near term. Sunday the 16th, though, is a write-off. It drops to ankle-slappers, maybe a foot and a half, with a long period but no size. The wind goes onshore, and it’s messy.
The whole stretch from Sunday through Thursday is flat. I’m talking barely a ripple. There’s a few pulses of long-period swell from the west-northwest, but it’s all of 1 to 2 feet. There’s nothing to get excited about. You’d be better off checking the tide pools.
We get a little glimmer on Thursday the 20th and Friday the 21st with some longer-period south-southwest groundswell, but the size is still only 2 to 2 feet. The energy is moderate, but you’ll need a longboard and a lot of patience. There are a couple of glassy windows, so it could be a fun, mellow paddle, but it’s not breaking any records.
The rest of that week is pretty ordinary. A bit of south-southwest swell bumps up the energy slightly around the 24th and 25th, but the winds are mostly cross-onshore. The standout of the entire run is Tuesday the 25th. The wave height is still just over 2 feet from the south-southwest, but the energy is strong, and the morning is dead glassy. That long-period swell, around 16 seconds, will provide some clean, well-formed waves. It’s not big, but the quality will be there. That’s the one to set your alarm for.
After that, it’s all downhill again. The last few days of the month are small, with messy winds and poor shape. There’s a bit of south-southwest energy around the 28th and 29th, but the wind will kill it.
So, bottom line: Saturday morning the 15th is your safest bet for a fun, clean session. And Tuesday morning the 25th is the one with the most quality, but you’ll be on a longboard. The rest of it is a waiting game.
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.
