The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for Sandy Mouth over the next couple of weeks.
To be straight with you, the outlook is pretty grim. We’re staring down a long, dry spell with no real surf to speak of. The entire 16-day window is a bust. There’s a gap from the start right through to the end, with only a tiny flicker of life on the 10th of August that’s still not worth paddling out for. For Sandy Mouth, this kind of flat, blank run is more normal for this time of year, so don’t be too surprised. Forecasts can change, but right now, it’s a waiting game.
Sandy Mouth is an exposed, consistent spot, but the swell just isn’t cooperating. The water temp is about average for the time of year, nothing unusual there. The energy in the water is weak, with combined swell energy values barely reaching two digits (at best 76), so there’s just no push.
The only day that even shows a pulse is Monday, August 10th. The morning sees a 4 ft swell from the NNW, with a short period of 5 seconds. That’s a weak, short-period swell, and combined energy is only 75. The wind is a light cross-offshore from the SSE, so it’ll be clean, but the wave quality is still described as "surfable waves but very ordinary conditions." It’s not worth getting excited about. After that, it drops straight back to nothing.
The rest of the period is a mix of onshore, cross-onshore, and cross-offshore winds, with swell heights mainly between 0.3 ft and 2 ft, and periods all over the shop. Nothing here will hold a face. For the few days with offshore wind (like August 2nd or August 8th), the swell is simply too small to do anything with.
Stick to the sand between your toes for now, boys. The surf will be back eventually.

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.
