The Lowdown
Alright, let's get into it for your local stretch. We're looking at a bit of a mixed bag over the next couple of weeks. The swell is going to be on the small side for most of it, so don't expect any big, powerful days. We'll have a long wait for the best of it, but there are a couple of windows where it should clean up nicely.
The main break to focus on is Disappearing Sands, which is an exposed, inconsistent spot that works best on a WNW swell. The water temp is pretty much what you'd expect for this time of year, nothing unusual there.
The forecast kicks off this Friday the 11th. It's not going to blow you away, but it's a start. Friday morning you've got some rain showers with a light west wind on it, not ideal. But Friday afternoon looks like the first real highlight. The wind is set to go glassy - dead calm - and we've got a small 2ft swell rolling in from the SSW. The period is a very long 15 seconds, which is proper groundswell, giving the waves some real shape and push. The combined energy is moderate (211), and the conditions should be clean and glassy. Just keep in mind this spot is inconsistent, so it might take a while for a set to come through.
Saturday the 12th and Sunday the 13th are a write-off. The swell drops to 1ft and the wind is rubbish, either onshore or cross-onshore, making for poor conditions. Not worth paddling out.
We get a bit of a lull through the start of next week. Monday the 14th and Tuesday the 15th mornings are poor, but Tuesday afternoon shows some promise. The wind goes glassy again, with a 2ft SSW swell and a very long 19-second period. The combined energy is good, moderate to strong (360). Not a standout, but a decent little session if you're keen.
The next real standout is looking like Wednesday the 16th. The afternoon session is the one to circle. We've got a glassy wind, a slightly bigger 3ft swell from the SSW, and a very long 18-second period. The energy is strong (432), and we're expecting good surf. Still small waves, but it'll be clean and lined up. This is about as good as it gets for this stretch.
Friday the 18th is another one to keep an eye on. The morning is a bit marginal, but the afternoon looks very good. Winds go glassy again, with a 2ft SW swell and a 17-second period. The energy is strong (525), and it's setting up to be a really fun, clean session. This might be the best of the whole run.
After that, things start to fade. The swell hangs around but the wind gets messy through the weekend of the 19th and 20th, turning cross-onshore and ruining the surface. The following week from the 21st through to the 23rd sees the swell drop right off to 1ft or less, with weak energy and poor wind. That stretch is a total dead zone, nothing worth chasing.
From the 24th we start to see a tiny pulse of new energy, but the winds are still a problem. It's a long wait for anything rideable again. We're looking at a gap of several days there with no real recommendations.
The pick of the bunch is Friday the 18th afternoon at Disappearing Sands. The glassy wind and that long-period groundswell should make for some super clean, if small, waves. Given it's inconsistent, you'll want to be patient.

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.
