The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu for Sandy Mouth over the next couple of weeks.
Straight up, it's a bleak picture for the foreseeable future. We're looking at a solid 16-day stretch with no good surf on offer. The first ten days are a write-off, with poor surf conditions and wind that just won't play nice. The swell is tiny to start, with the combined wave energy barely registering at 41 (moderate energy) on the 26th, and it's a short-period 8 second swell – not enough push to get excited about. The water is sitting at 66°F and that's a massive 4°F warmer than usual for this time of year, which is a very notable anomaly.
From the 28th of August, we start to see some size, with a 4ft to 6ft swell from the WSW, but the wind is all over the place – onshore, cross-onshore, or strong cross-shore. The combined energy jumps up to 126 (moderate energy) on the Friday morning, but with a fresh cross-onshore and lumpy conditions, it's just not going to be worth paddling out. The wind strengthens into the weekend, with gusts up to 28 mph on the 29th, making it a mess. The swell gets even bigger, hitting 8ft on the 31st of August from the W with a 9-second period, and the combined energy is a strong 1098, but it's accompanied by a moderate cross-onshore and choppy conditions. For a beach break like Sandy Mouth, this setup is looking far more interesting for kite surfing than paddle surfing.
Into the first week of September, the pattern doesn't change. The wind is still predominantly onshore or cross-onshore, and the swell continues to be short-period and messy. There's a tiny glimmer on the 5th of September, where the morning shows a clean 4ft swell from the W with a longer 10-second period and light offshore wind from the WNW, but the model only calls it a "marginal surf forecast" and the score says it's a no-go. Even then, it's a long way out and the consistency is poor. The 9th of September sees a brief period of clean conditions with a cross-offshore wind, but the swell is a weak 4ft from the NW with a short period of 6 seconds, and the combined energy is only 102 (moderate). It's surfable, but nothing to write home about.
Honestly, there's no standout here. It's a blank run, and for an area that's usually fairly consistent, a run this long is a bit of a bummer. But forecasts can change, so don't lose hope entirely.
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.
