The Lowdown
Alright, Rusty here. Let's talk about Sandy Mouth.
It's a grim outlook for the next 16 days. This spot is consistent, usually sees a lot of west swell, but the wind is the enemy here for almost the entire run. We're looking at a lot of lumpy, choppy, blown-out conditions.
The only real chance for a decent wave is early on Saturday morning, the 5th. It's a short window, but it's the only time the stars align. We've got a 4ft W swell with a 10-second period, so the shape and energy are there. The combined energy is 249 (moderate), giving it some life. The main thing is the wind is dead calm – glassy. That's the key to a clean surf. The water temp is 66°F, which is about 4° warmer than average for this time of year, so it's noticeably warm. It'll be crowded, no doubt, but this is the session.
After that Saturday morning, it's a rough stretch. Sunday the 6th drops to tiny 2ft swell and weak energy. The next week, from the 7th through to the 15th, the swell size comes up, sometimes over 7ft, but it's constantly hammered by fresh onshore winds. It's gonna be a choppy, heavy mess. Honestly, that setup is more of a kite surf zone than a paddle surf spot. There's a tiny glimpse of light on the 15th with 2ft and light offshore breeze, but it's got almost no energy, so probably a waste of time.
It's a tough run. The only one to aim for is that glassy Saturday morning, 5th September.
Rusty, signing off.

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.
