The Lowdown
Hey, Rusty here. Truth is, we’re in a long, quiet stretch. Aldinga Beach is the only break in the picture, and for nearly the whole 16-day window, the surf is flat-as. Don’t get your board bag ready just yet.
From the start of August through the 9th, it’s practically nothing – swell heights are 0.3ft to 0.6ft at best, with teeny energy readings (single digits to low teens). Winds are mostly cross-off or cross, but there’s no wave to work with.
The first bit of size shows on Sunday the 9th afternoon: a 5ft swell from the WSW, but with a short 6-second period and onshore wind at 22 mph, it’s just slop. The combined energy hits 160 (moderate), but with thunderstorms possible, it’s not a go.
Monday the 10th and Tuesday the 11th have some bigger numbers – Tuesday morning sees a 7ft swell from the NW and energy at 278 (moderate-strong). But that’s onshore wind at 12 mph, and the period is only 6 seconds – close-out city. By Tuesday afternoon, the wind picks up to 19 mph from the WNW, making it a kite-surfing kind of day, not a paddle session.
From Wednesday the 12th, it drops back to tiny junk, 0.3ft to 1ft for days. There’s a glassy moment on Friday the 14th morning with a 1ft swell, but that’s barely a ripple. Saturday the 15th afternoon is dead calm and glassy with 0.6ft – pretty, but not surfable.
No standouts here, folks. This is a flat run for Aldinga Beach – an inconsistent spot even when there’s swell. The water temp is 57°F, about average for this time of year. Save your wax, keep the board in the rack. Forecasts can flip, but right now it’s a long, quiet wait.
Rusty.

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