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.
Honestly, it’s a tough stretch. The whole 16-day window is a bit of a struggle. We’ve got a long run of what I’d call "park the truck and stay in the truck" conditions. The wind is just messy, and the swell is tiny. For the first two weeks, there’s nothing to get excited about. The first recorded day with a sniff of surf is Monday the 3rd of August, but it’s woeful – a tiny 2 ft W swell with a weak energy of 39, and a cross-onshore breeze. It doesn't get any better for ages. We’re looking at a solid 15-day gap with no real recommendation.
The water temp is sitting around 65°, which is a touch warmer than normal for this time of year, but you won't be caring about the water temp when you're scratching for a wave in 0.7 ft slop. Wednesday the 5th sees a bit of a spike in the swell – 6 ft from the W – but the wind is howling onshore at 19 mph. The energy jumps to 311 (moderate), but with that wind, it's just a washing machine. That setup is more interesting for kite surfing than paddle surfing, to be honest.
The only tiny glimmer of hope comes right at the tail end. On Tuesday the 18th of August, we finally get a "surfable" call. The morning shows a 4 ft W swell (133 energy) with a light cross-offshore breeze from the NE. The wave comment says "surfable waves but very ordinary conditions," which is about as good as it gets. It's a 7-second period, so it's windswell, but at least the wind is offshore. The water temp anomaly hadn't been noted for that last entry, but it's been a touch warmer.
That Tuesday morning is the only standout, and even then it's a "maybe you can get a few" kind of session. It’s not gonna be a day for the history books.
Keep your chin up, Sandy Mouth. It tends not to stay this poor for long, and forecasts can change.
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.
