The Lowdown
Right, grab a coffee, let’s have a look at what’s on offer for Sandy Mouth over the next couple of weeks.
First thing to say, mate, it’s a slow start. Really slow. The water temp’s sitting at 64°F right now, which is a touch warmer than normal for the time of year, but that’s about the only thing that’s happening. For the rest of July and into the first few days of August, we’re looking at a long dry spell with no decent surf to speak of. The wind is mostly cross or cross-on, and the swell is tiny – hardly breaking 3ft on the best of those days, with periods of only 4-6 seconds. That’s just windslop, not surf. The combined energy barely gets into double digits (16 on the 20th, 39 on the 21st), so you’re not missing a thing.
The only true ray of light, the only standout in this whole 16-day window, lands on Friday, the 31st of July. The morning session is the one to pencil in. The wind swings around to an easterly offshore breeze at 12 mph, and that’s a game-changer. Clean, peeling conditions. The swell jumps to 8ft from the west, with an 8-second period. That’s not a long period, but the energy is serious – combined energy of 737 – and that’s the only time the forecast says “expect very good surf conditions.” That’s a morning for the experienced crew. At 8ft, it’s pushing into expert territory if you’re not comfortable in bigger, powerful waves. The afternoon of the 31st drops off to 5ft, still clean but with less punch.
The few days after that tail off again. The 1st of August has a little 3ft groundswell with a 9-second period, but the wind’s all over the place. By the 4th of August, the swell bumps back up to 5ft from the west, but the wind is absolutely howling onshore from the WSW at 16 mph, which will ruin it. The combined energy is high (384-442), but with that wind, it’s just a washing machine. Honestly, for a kite surfer, the 4th of August afternoon might look more interesting than for a paddle surfer.
So, to sum it up: save your energy for the morning of Friday, 31st July. That’s your window. Everything else is a rest day.

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.
