The Lowdown

Alright folks, it’s Rusty here, and I’ve been staring at the charts for Sandy Beach. Let me tell you, it’s a tough stretch ahead. The whole 16-day window is a bit of a write-off for decent waves, and I’m not gonna sugarcoat it – there are no good surf options to recommend.

The Long Grind

We’re looking at a dry spell that basically runs the entire forecast period. From the start, we’ve got a messy, choppy ocean with the breeze howling out of the ENE, 15 to 25 mph most days, and it’s pinning the swell. The water temperature here is a warm 81°, which is pretty average for this time of year, but you won’t be enjoying it much unless you’re a kite surfer. With that constant cross-onshore to cross-shore wind, Sandy Beach is going to be a lumpy, cross-chop mess. We’re talking weak, jumbled waves that are no good for a paddle surfer. In fact, with the wind and swell setup, this place looks far more interesting for kite surfing than for a traditional surf session. The combined swell energy sits in moderate territory for most of it, but that doesn't mean a thing when the wind is shredding it to bits.

A Glimmer That’s Still Dirty

Come August 31st, Monday afternoon, we finally see a jump in swell size to 8 ft from the ENE. But here’s the kicker – the wind is still up at 22 mph from the NE, making it a messy cross-shore wind. The size is there, but the quality isn’t. It’s still lumpy and the report calls it “marginal.” For a beach and reef spot like this, that much wind and size just makes it a slog. It’s not a standout; it’s just the least ugly day in a bad bunch.

The Best of a Bad Bunch

Honestly, the closest we get to anything surfable is September 8th, Tuesday morning. We see a brief window where the wind drops right off, swinging to the SE at only 3 mph and going offshore. The swell is still a clean 5 ft from the ENE. For a moment there, the ocean might glass off. With that offshore wind, the waves could have a clean face. This is the one window of the whole run that could be okay for an intermediate surfer, but it’s a long way out and you’ve got to take that “marginal” forecast with a pinch of salt. It’s a promise, but not a guarantee.

So there you have it. A long, frustrating wait with one brief, hopeful Tuesday morning on the horizon. Keep the wax warm and hope the forecasts improve.

Rusty.

Information about the Sandy Beach Surf forecast

The above surf forecast table for Sandy Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Sandy Beach can be found by selecting the local surf guide option on the grey menu. Our Sandy Beach 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 Beach) 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 Beach 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.
