The Lowdown
Alright folks, Rusty here. Let’s look at what’s on offer for Sandy Mouth over the next couple of weeks.
Honestly, it’s a pretty grim stretch for surf. The whole 16-day window is a real struggle. There’s one very brief, half-decent window, but it’s thin. For most of the period, the wind is a mess, and the swell is either too small, too weak, or just poorly aligned.
Things start off poor on Monday, August 31st. We’ve got a 7ft west swell, but the wind is a fresh 19 mph onshore from the west-northwest, making it a total washout. The water temperature is 66°F, which is a solid 5°F warmer than usual for this time of year – that’s notably warm. The combined swell energy is moderate (847), but it’s all for nothing with that wind.
The next few days are a write-off. Tuesday and Wednesday are small, choppy, and cross-onshore. Thursday and Friday are a bit bigger but still blown out. The combined energy jumps on Friday afternoon to 356 (moderate), but it’s messy.
Now, there is one tiny glimmer. On Saturday morning, September 5th, we get a brief window of pure glass. The wind swings to a light southeast breeze at just 3 mph, glassy conditions. The swell is a small 3ft from the west at 9 seconds. The combined energy is weak (135), but the conditions are clean. If you’re desperate for a paddle and have a log, this is your only chance. It’s surfable, but very ordinary.
After that, it’s back to the doldrums. Sunday the 6th is clean with a light cross-offshore breeze, but the swell is tiny – 2ft and 2ft with combined energy of just 60 and 41 (weak). The whole second week is a bust. From Monday the 7th through to Tuesday, September 15th, the swell barely registers. The combined energy stays below 200 for the most part, and for days on end, it’s below 20. A few mornings have clean cross-offshore winds, but with swell heights of 0.3ft and 0.7ft, it’s not surfable. There’s a long period (12 seconds) on the 15th, but it’s only 0.7ft and cross-shore – just a bump.
So, bottom line: there’s nothing to get excited about here. The only real standout is that Saturday morning glass-off, but it’s tiny. If you’re a beginner, there’s nothing for you. For experts, the whole window is a no-go. This is one of those stretches where the forecast is just flat and blown out. It won’t last forever, but for now, the board stays in the car.
Rusty.

A general guide to surfing at Sandy Mouth can be found by selecting the local surf guide option on the grey menu.

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.
