Table - best surf conditions forecast for Sandy Beach over the next 16 days.
Alright folks, Rusty here. Let’s be straight with you – this outlook is a rough one for the Sandy Beach area.
Look, we’ve got a 16-day window staring at us, and honestly, there isn’t a single moment in that whole stretch where the stars align for a decent paddle. The wind is the main culprit. From Saturday the 11th right through to Sunday the 26th of July, we’re looking at a relentless cross-shore breeze, mostly from the ENE, blowing at 18 to 25 mph. That’s a strong breeze that’s going to chop up any chance of clean waves. The swell is coming from the ENE too, so it’s all onshore wind with that swell direction, which is a recipe for messy, lumpy surf.
We do see some energy pop up, with combined swell energy hitting moderate to strong values – like 638 (moderate) on the 11th morning, and even hitting 860 (strong) on the 23rd morning. But that energy is wasted on these conditions. The wave comment for every single entry in the data is “poor surf conditions,” and I’m not going to argue with that. The water temperature is sitting around 79°F with a tiny anomaly, so it’s about average for the time of year, but that’s the only nice thing I can say.
If you’re a kitesurfer, this setup might look interesting to you, with that consistent wind and some bumpy swell. But for a surfer looking for a ride? Forget it. The best advice I’ve got is to wait for a change in the forecast, because this run of poor conditions is a long one. It won’t stay this way forever, but for now, leave the boards in the car.
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.
