The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Sandy Mouth over the next couple of weeks.

Right off the bat, I gotta be straight with you – this is a tough one. The entire 16-day window is basically a write-off for any decent surf. We’re looking at a long, dry spell with nothing worth paddling out for. The first few days are a total bust, and the pattern doesn't really look like it’s gonna change much.

Starting from Tuesday, July 21st, we’ve got tiny 1 ft swell from the west with a weak period of 10 seconds. The combined energy is a measly 34 – that’s just not enough to push a ripple. To make matters worse, the wind is a messy cross-on from the NNW at 12 mph. The water is sitting at 64°, which is a touch warmer than normal for this time of year, but that’s small comfort when there’s nothing to ride.

Wednesday the 22nd and Thursday the 23rd are more of the same – small, weak swell from the NNW, with periods dropping to a pathetic 5 seconds. The wind might ease up a bit on Thursday morning with a glassy window, but the swell is still only 3 ft. It’s clean, but there’s just no power behind it.

We roll into the weekend of the 25th and 26th, and the swell tries to pick up a little, hitting 4 ft to 5 ft on the Sunday the 26th. The combined energy climbs into the moderate range (119 to 137), but the wind is howling from the NW at 12-16 mph, cross-on and choppy. It’s a mess.

Then on Monday, July 27th, we see the biggest swell of the whole forecast – 5 ft from the WNW with a 7-second period and energy hitting 195. The wind is onshore from the WNW at 9 mph. That’s about as interesting as it gets, but with the onshore wind and the short period, it’s going to be a bumpy, lumpy closeout. Not worth the paddle.

The rest of the first week and into the second week is just a repeat. We get a little bump on the 1st and 2nd of August, with swell around 3 ft to 4 ft from the west, but the wind is onshore at 16-19 mph. The energy levels are moderate (141 to 225), but the quality is just not there. The forecasters are calling it “poor surf conditions” across the board, and I can’t argue with that.

There’s a moment on the 4th of August where the wind goes light and cross-off from the SE, which would clean things up, but the swell is only 2 ft with a 7-second period. It’s a tease.

Honestly, for a beach break like Sandy Mouth, this setup is more interesting for the kite surfers than for us paddle surfers. The onshore winds and the lumpy conditions just aren’t our friend. There’s no standout window here. The best you can hope for is a tiny, clean bump on the 23rd morning, but it’s a long shot.

Keep an eye on the charts, but for now, I’d save the wax.

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.
