The Lowdown

Hey, Rusty here. Looking at Sandy Beach over the next 16 days, I gotta be straight with you – there’s really nothing worth paddling out for. The whole stretch from July 14 through to July 29 is a write-off. Every single session shows poor surf conditions, with only a couple of marginal windows that still aren’t worth your time. The winds are mostly cross or cross-onshore and fresh, creating lumpy, choppy mess. Swell heights bounce around but never get clean. The combined energy (moderate to strong, ranging from 84 to 1081) is there but it’s all wasted on bad wind. Even the longer period swells that roll in later (like 14–23 seconds) don’t save it because the wind just chops it up. Sandy Beach is a fairly consistent spot normally, but this run is a total dud. If you’re desperate, the only hint of anything rideable is on Friday afternoon July 24, with a 3ft E swell at 17 seconds and moderate cross-shore wind, but still lumpy – and then Monday morning July 27 with 3ft E swell, 14 seconds, again moderate cross-shore. But both are marginal at best, with cross-chop. Honestly, I’d wait for a better forecast. This area often turns around quickly, but this 16-day window is a bust. Stay tuned – forecasts can change. 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.
