The Lowdown
Alright folks, Rusty here. Let's have a look at what the next couple of weeks are serving up for Sandy Mouth.
Right off the bat, it's a bit of a waiting game. The first week is a write-off, I'm sorry to say. We’ve got a persistent cross-onshore wind, mostly from the WNW, that just ruins the surface. The swell is there, but it's short-period, choppy wind-slop, not the kind of waves you paddle out for. The wave energy is weak, mostly sitting in the double digits over the first few days. You're looking at knee-high junk at best. It’s a grim start, and that stretch of poor conditions runs all the way from Wednesday the 5th through to the morning of Tuesday the 11th.
There’s a tiny glimmer on the morning of Wednesday the 12th. The wind goes glassy, dead calm, with a light offshore breeze from the NW. The swell is only 2ft from the west, but with a period bumping up to 10 seconds, it’s got a bit more shape. The wave energy is still low, but for the first time in the forecast, it's surfable. It’s not a standout, just a tiny window of clean but tiny waves.
After that, we’re back into the doldrums of poor conditions through the rest of the week, with the wind swinging back onshore and chopping everything up. The swell tries to build on the 13th and 14th, hitting 3ft to 4ft, with energy climbing, but the cross-onshore wind just kills it. It’s frustrating to watch.
Now, the real, and only, standout is for the morning of Thursday the 20th of August. This is the one to circle on the calendar. The wind is set to go glassy again, with a light southerly breeze. The west swell is a solid 4ft with a period of 9 seconds, and the combined energy is healthy. The report says "expect good surf conditions," and with the wind as clean as it gets, this is the best window we’ve got. It’s a long way off, so don’t book the week off yet, but it’s the only proper chance for a decent session.
The rest of the second week looks messy. The wind stays onshore, and you’ll see a big pulse of energy on the 18th, with swell heights near 8ft and energy readings over 800, but it’s all blown out and won't be anything but a washing machine. That’s kite-surfing territory, not for a paddle board.
So, to sum it up: the first week is a total blank. The 12th offers a window of clean but tiny waves. The one to get excited about, with a bit of luck, is the morning of the 20th of August. Keep your fingers crossed that forecast holds.
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.
