The Lowdown

G’day, Rusty here. Gotta be straight with you—there’s nothing worth paddling out for in the 16-day window, from August 9 right through to August 24. Not a single session pops. The finder’s given us a blank run, and looking at the guidance for Aldinga Beach, it’s a tough stretch. The break’s inconsistent at the best of times, so a dry spell like this isn’t totally out of character. Still, forecasts can shift, and it won’t stay poor forever.

The whole period is plagued by onshore and cross-onshore winds from the SW and WSW, with only a few fleeting moments of lighter breezes. The swell barely gets off the ground—most of it sits at 0.3 ft to 1 ft, with a weak combined energy (single-digit to low-double-digit values). A small pulse shows up on August 10 morning with a 5.6 ft WSW swell and moderate energy of 216, but it’s blown out by a fresh 18.6 mph onshore wind, making it a total mess. That pattern repeats around August 20 afternoon, with a 5.2 ft WSW swell and 183 energy, but again, choppy cross-onshore winds spoil it. For a spot like Aldinga Beach, which is fairly exposed to SW swells and needs that direction, the wind just kills any chance of shape. There’s no standout day, no clean swell window—just a long, flat, windy gap.

Hang in there, check back later. This is one to sit out.

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.
