The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the table for the next couple of weeks.
Well, straight up I gotta tell you, it’s a tough stretch. The forecast is showing a whole lot of "poor surf conditions" for Sandy Mouth. We’re looking at a real dry spell.
The first real chance of anything that might get you interested is around Monday the 7th. There’s a solid swell building, hitting 7 ft from the west with a long 13-second period. The combined energy is strong (1487). But here’s the kicker – the wind is howling onshore from the west at 16 mph. That’s gonna make a mess of it. This kind of size and power with that wind is really only for the experts, and even then, it’s going to be a battle. The swell drops a bit into Tuesday, still with onshore wind, and the period shortens up.
For the rest of the first week and into the second, it’s a frustrating story of small, weak swell and uncooperative winds. The water temp is about average for this time of year, so no surprises there.
There is a glimmer, though. Check out Sunday the 13th. The swell is tiny, only 2 ft, but the wind is going offshore from the east-northeast at 19 mph. That’s a fresh offshore breeze, and it’ll have the surface glassy clean. The combined energy is weak (70), but if you’ve got a longboard and you’re desperate for a trim, that morning session could be your only clean window. The following morning, Monday the 14th, is even cleaner with a gentle offshore from the east at 9 mph, but the swell is a mere 1.0 ft.
Then we hit Tuesday the 15th morning. The swell is still tiny at 2 ft, but the wind is glassy – dead calm. That’s as clean as it gets. The period is a short 5 seconds, so it’s gonna be weak and wonky, but for a total glass-off, it might be worth a paddle.
After that, the second week is a write-off. We’re talking about strong cross-shore winds and even smaller surf. The whole period from the 16th to the 20th is just not worth getting excited about. It’s a long blank run of poor conditions.
So, what’s the best on offer? Honestly, there are no standouts. If you’re a die-hard, the cleanest conditions are on the morning of Sunday the 13th with that offshore wind, but the swell is tiny. The glassy morning of Tuesday the 15th is the other one. For the rest of it, I’d say save your energy and wait for a better forecast. This area tends not to stay this flat for too long, so hopefully, the next outlook will be a different story.
Rusty.

Information about the Sandy Mouth Surf forecast
The above surf forecast table for Sandy Mouth provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Sandy Mouth can be found by selecting the local surf guide option on the grey menu. Our Sandy Mouth 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 (Sandy Mouth) 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 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. 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.
