The Lowdown

Alright folks, Rusty here. Let’s talk about what’s on the cards for Sandy Beach over the next couple of weeks. I’ve gotta be straight with you – looking at this 16-day window, there isn’t a single day I’d point at and say, “Yeah, that’s the one.” The whole stretch is pretty grim.

Right out of the gate, Friday the 28th through to Thursday the 10th of September is just a write-off. We’ve got a consistent cross-shore wind from the ENE, sitting around 22 to 28 mph, which is just trashing any chance of a clean wave. The swell is all over the place – starting small at 3 ft from the south with a long 14-second period, then switching to a messy ENE windswell with a short, weak 6-second period. The wave energy is moderate at best, but it doesn't matter because the wind is ruining it. The surf commentary calls it “poor surf conditions” every single time through to the 3rd of September.

By the time we get to Thursday the 3rd, the swell is still there at 6 ft to 7 ft from the ENE, but the period stays short and the wind is relentless. There’s a tiny glimmer on Friday the 4th of September, where the swell ticks up to 7 ft – 7 ft with a period hitting 11-12 seconds, and the wave energy gets strong. But again, that fresh cross-shore breeze just chops it all up. The commentary says it’s “marginal surf forecast” at best. For a beach-and-reef setup like Sandy Beach, with that much wind and that much swell, this spot is looking far more interesting for kite surfing than paddle surfing right now.

As we push into the second week, things actually get worse instead of better. By Monday the 7th of September, we’re looking at 10 ft, then 12 ft on Tuesday the 8th, with the wave energy going through the roof. That’s serious size – only for experts. And still, that fresh to strong cross-shore wind is blowing 25-28 mph. Then by Thursday the 10th of September, it gets properly nasty with a severe gale from the ESE at 47 mph, totally blowing the place out.

The last couple of days, Saturday the 12th of September, the swell drops right back to 2 ft and the wind finally eases, but we’re looking at a cross-onshore or cross-shore breeze again. The period gets long at 16 seconds, but the waves are tiny and the wind isn't helping.

Honestly, there isn’t a standout here. Not one. The water temperature is a normal 81° for the time of year. But with no clean conditions and a forecast that just stays stubbornly poor, it’s a blank run.

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.
