The Lowdown
Alright, Rusty here, breakin' it down for Sandy Mouth.
Honestly, the first few days are a total bust. The swell is flat and the wind is trash, makin' for nothing but a choppy mess. You can leave the board at home for the 14th and 15th of August – it's just not worth it.
We get a tiny glimmer on Wednesday morning, the 16th of August. The wind turns offshore from the east, and we get a little 0.7m swell from the west. The energy is still weak (94), but it's clean. You'll be scratchin' for waves, though.
The only real standout is Thursday morning, the 17th of August. The swell bumps up to a solid 3ft from the west, with a 11-second period – that's some real groundswell. The energy is up into the moderate range (230), and the wind is a light cross-shore. It'll be a bit funky, but it's the most power we see all forecast. For a beach break, a long period like that can make the waves close out, so you gotta find the right bank. Still, it's the best of a bad lot.
After that, it's back to the slow grind. The energy drops off, and the wind stays messy for the rest of the run. There's a clean morning on the 24th of August, but the swell is tiny (2ft) and the energy is weak (114). Clean, but not worth a paddle.
Water temp is about normal for the year. Nothin' else to shout about.
So, a long, quiet stretch. The morning of the 17th of August is your best shot, but don't get your hopes up. The rest is mostly flat or blown out.
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.
