The Lowdown

Alright folks, Rusty here. Let's take a look at what we've got coming up at Sandy Mouth.

Straight up, the next two weeks are looking pretty tough. There's a heap of swell on the cards, but the wind just won't play ball. We're in for a frustrating stretch. It kicks off on Monday the 7th with a 6ft west swell, but that's getting hammered by a 12 mph cross-on breeze, making it choppy. The water temp is about average for this time of year.

The whole first week is a write-off. From Monday the 7th right through to Monday the 14th, every session is plagued by onshore or cross-onshore winds, ranging from 12 mph up to a fresh 22 mph. Even when there's some moderate wave energy around (like 1237 on the Monday morning), the conditions just aren't there for a good paddle. You'll get periods of rain, clouds, and a whole lot of lumpy, messy surf.

We then hit a bit of a lull around Thursday the 10th, with tiny 2ft to 2ft swell and weak energy (down to 50), so you can write that off completely. The following weekend, starting Saturday the 12th, has a bit more size, up to 5ft, but again, it’s cross-on and lumpy.

Into the second week, there’s a flicker of hope on Tuesday morning the 15th. We’ve got a clean-looking 3ft groundswell from the WNW with a nice long 12-second period. The wind drops right out to almost nothing, just 3 mph. The combined energy is a moderate 360. This is the best we’ll see, but it’s a small window and the "marginal" tag on the forecast means it could be tricky with the tide. Still, for a brief moment, it could be glassy and fun on a longboard. That afternoon, the wind gets back on it and it’s gone.

Thursday the 17th sees a serious pulse of energy, with a massive 13ft swell hitting and energy readings of 3345. That’s big, powerful, and well over 8ft – strictly for experts only. But it’s pinned by a 22 mph onshore wind, so it'll be a washing machine. Not worth it.

The last few days from the 19th onward are more of the same: solid west swell (7ft to 10ft) but constantly crossed-up by strong onshore winds. The energy is strong (up to 1147), but the quality is zero.

To be honest, with the persistent onshore flow and the exposed nature of Sandy Mouth, if you see that big swell on the 16th and 17th with strong winds, the setup looks far more interesting for kite surfing than paddle surfing.

The one and only standout, if you can call it that, is the small window on Tuesday the 15th. That’s the only time you might get a clean, workable wave for a log.

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.

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.
