The Lowdown
Right then, let’s have a look at what’s on the cards for Sandy Mouth over the next couple of weeks. I’ll be honest with you, it’s a bit of a slow burn. We’ve got a fair stretch of pretty ordinary conditions to sit through before we see anything worth paddling out for.
The forecast opens with a run of poor surf. From Tuesday the 8th right through to the 17th of September, it’s a real mixed bag of cross-onshore winds and messy, choppy surfaces. Swell sticks around but the wind just wrecks it. There’s a bit of moderate wave energy in there at times, like 497 (combined swell energy) on Tuesday the 8th with a 6ft swell from the west, but it’s coming in with a 25 km/h cross-onshore breeze. It’s just not surfable in any enjoyable way. It’s not until the middle of the second week that things start to shift.
Now, there’s one window that looks like it could be the standout. Friday the 18th of September into the morning of Saturday the 19th. On the afternoon of Friday the 18th, we get a 4ft west swell with an 11-second period – that’s a nice bit of groundswell energy, giving the waves a bit of shape and power. But the real winner here is the wind: it’s glassy. Dead calm. That’s the kind of condition that turns a modest swell into a beautiful, clean session. The combined swell energy is 289, which is moderate, and the wind is so light it’s practically still. For a consistent, exposed west-facing beach like Sandy Mouth, a glassy afternoon with a 4ft groundswell is a proper treat. The morning of the 19th will still be clean with a light cross-offshore breeze, but the swell eases a touch to 3ft.
Before that, Sunday the 13th of September has a brief moment where the wind goes onshore, light at 10 km/h, with a 5ft west swell. It’s flagged as marginal, and that light breeze might keep it a little lumpy, but it’s the closest we get to a clean surf before that Friday window.
After the Friday highlight, it fades again. Sunday the 20th sees the swell drop right off, and by Monday the 21st we get a pulse of very long-period swell from the west-northwest (16 seconds, 15 seconds) with a strong 45 km/h cross-onshore breeze. That’s just a messy, blown-out situation. The good window is short, but for those of you who can sneak out on Friday afternoon, it’s the one to aim for.
Keep an eye on the forecasts though – it doesn’t stay poor forever around here.

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 Sandy Mouth 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.
