The Lowdown
Right then, let’s have a look at what’s on offer for Sandy Mouth over the next couple of weeks.
Straight up, I gotta be honest with you – it’s a tough stretch. We’ve got a real blank run here. The forecast is showing day after day of poor surf conditions right through until the very end of the period. There’s a solid gap of about eight days with no recommendations at all, so don’t be planning any sessions just yet.
Starting off this Sunday the 13th, we’ve got some waist-high swell coming in from the west, around 5 ft, but the wind is a cross-onshore breeze at 12 mph, making it choppy and messy. The combined wave energy is moderate at 377, but the surf is just poor. It stays in that same vein through Monday and Tuesday, with the swell dropping a bit and the wind actually picking up to a fresh 19 mph on Tuesday, which brings in a lumpy 6 ft west-northwest swell.
Wednesday the 16th sees the energy jump up to 641 – that’s moderate to strong – with a 6 ft west swell, but again, it’s cross-onshore and lumpy. The water’s a warm 65°F which is much warmer than normal for this time of year, over four degrees above average, so at least it’ll be comfortable if you’re just standing on the beach.
The wind doesn’t let up all week. Thursday the 17th has 7 ft waves but it’s still messy. Friday the 18th sees the wind howling from the southwest at 25 mph, making a right mess of a 6 ft swell. Honestly, with that kind of wind and a beach setup, this looks more interesting for kite surfing than paddle surfing.
We finally get a bit of a change on Tuesday the 22nd of September. There’s a 8 ft west-northwest swell coming in with a short period of 7 seconds, and the wind is light from the north at 6 mph, creating a cross-shore ripple. The energy is a strong 586. The conditions are only marginal, with a score of 2 out of 10 – questionable tide and surf quality. This is the only real blip of hope, but it’s a long way off and not exactly a standout. After that, the surf just fades away into tiny, clean but small waves for the rest of the month, barely reaching your shin.
So, the bottom line: there’s no true standout here. The best bet, and I’m stretching it, is that Tuesday the 22nd morning, but don’t get your hopes up. The area is having a proper flat spell, and it might just be one of those normal blank runs. Forecasts can change, but for now, keep the board in the car and the wax in the wrapper.

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.
