The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what’s heading our way over the next couple of weeks.
Right off the bat, I gotta be honest with you – it’s a tough stretch ahead. For the first eight days, from Friday the 4th right through to the morning of Saturday the 12th, it’s mostly a write-off. We’ve got consistent swell rolling in, but the wind is just relentless, hammering the coast from the west and northwest. That means blown-out, choppy, messy conditions day after day. There’s a big pulse of energy on Monday the 7th with a long-period groundswell from the west – combined energy hitting 1497 – but with that wind, it’s just not gonna be a pretty sight at the beach.
It’s not until the morning of Saturday the 12th that things get interesting. That’s when the westerly wind finally drops and we get a light offshore breeze from the northeast. The swell is small, around 3ft from the west, but with clean conditions, it’ll be rideable. For a spot like Sandy Mouth, which is exposed to the west and consistent, that’s your first real window. This one is for the patient surfer.
Then Sunday the 13th morning is another clean option. A light offshore from the east-southeast will groom a 2ft west swell. The water temp is about average for this time of year, so nothing wild there. It’s small, but clean.
After that, we go through a few more days of lumpy, wind-affected surf until we hit the real standout of the whole forecast. Wednesday the 16th morning. Now listen, this is the one to circle on the calendar. We get a glassy, dead calm morning with a clean 3ft west swell, period of 11 seconds – proper little groundswell. The combined energy sits at 233 (moderate), but with zero wind and clean lines, Sandy Mouth will be offering up some really fun, clean little waves. That’s the pick of the fortnight, no contest.
After that, Thursday the 17th and Friday the 18th mornings offer small, clean-ish surf with offshore winds again (3ft to 3ft from the west), but the magic of that glassy Wednesday morning is the real winner here.
So, in short: the first week and a half is a battle with the wind. If you can hold out, the morning of Wednesday the 16th is the session to chase. Otherwise, the mornings of the 12th, 13th, and 18th offer a little something if you’re scratching for a paddle.
Rusty.

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 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.
