The Lowdown

Right then, let's have a look at what's on the cards for Sandy Mouth over the next couple of weeks. To be straight with you, it's a pretty grim stretch. The swell window is open and there's energy coming through, but the wind just won't play ball. For a spot that needs clean conditions, this is one of those runs where you're better off waxing the longboard and waiting for a better day.

Alright, let's break it down. There's really nothing worth paddling out for in the first week. Wednesday the 12th kicks off with a tiny 2ft west swell, period around 10 seconds, and the combined energy is weak at just 96. The morning has a light cross-offshore breeze, so it's clean, but those waves are just poor. By afternoon, the wind swings cross-onshore and it's a write-off. Thursday the 13th sees a bit more size, up to 3ft, with the period stretching to 11 seconds – that's a longer-period groundswell, which is good for shape in theory, but the wind is cross-onshore again and the energy is moderate at 224. It's still messy.

Friday the 14th, we get a direct onshore wind with that 3ft swell, and the energy drops (104). Saturday the 15th is a complete mess – the swell jumps in period from a short, weak 5 seconds, but we're talking 4ft to 4ft coming from the north with a fresh cross-shore breeze at 19 mph. That's lumpy, choppy, and the energy is only 122 to 130 – honestly, that setup looks more interesting for kite surfing than paddle surfing. It stays that way right through until the middle of the following week.

The real story here is the lack of any good surf. There's a gap of several days – from the 12th all the way to the 19th – with zero recommendations. Everything is flagged as poor. The water temp is about average for this time of year, nothing unusual.

Then on Wednesday the 19th of August, we start to see a bit more size, with the swell hitting 5ft in the morning and 5ft in the afternoon, coming from the west-northwest. But the wind is howling onshore at 22 to 25 mph, and the energy is moderate to strong (262 and 217). It's a full-on onshore blast – un-surfable. That trend continues into Thursday the 20th, where the swell peaks at 7ft, with strong energy (844 in the morning, 494 in the afternoon). But the wind is still cross-onshore, fresh, and lumpy. For experienced surfers, there'll be power in the water, but you'll be battling a washing machine. Beginners should stay well clear – that's heavy stuff.

After that, the swell backs off again, but the wind never settles for long. Friday the 21st, the swell drops to 3ft, cross-onshore. Saturday the 22nd, it's tiny with light wind. There's a flicker on Sunday the 23rd with a 6ft west swell, but again, onshore winds and moderate energy (354). It's just not coming together.

If you're holding out for something, the very end of the period on Thursday the 27th of August shows a 8ft west swell with strong energy (904), but it's coupled with a fresh cross-onshore breeze. For experts only, and even then, it'll be a battle.

So, no standouts here, folks. It's a dry spell for Sandy Mouth. Forecasts can change, but right now, I'd keep the board in the bag.

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.
