The Lowdown
Alright, let's give it to you in feet and miles per hour. I'm Rusty, and I've been looking at the options for Aldinga Beach with a heavy heart. The whole 16-day outlook is a desert—not a single proper session worth getting wet for. It's a whole lot of flat, with a couple of ugly, blown-out bumps.
We start with a long gap of nothing. The first chance to paddle out is a write-off. Sunday the 26th of July, we've got a knee-high wave of 1ft from the WSW with a period of just 5 seconds. Energy is non-existent. Light cross-shore breeze means you can see the surface is clean, but there's nothing to ride. It's poor, and that carries on through Monday.
Tuesday the 28th sees the swell jump to 4ft in the morning and 7ft in the afternoon from the W, with the combined energy getting up there. Looks promising, but the wind is a screaming onshore 22 mph, turning it into a complete mess. That's not for a surfboard; that's for a kite. The period is still short on that wave, so it's just a lumpy crumble.
Wednesday and Thursday are back to small and messy. Friday the 31st through the weekend of the 2nd of August, it's flat. We're talking ankle-snappers of less than 1ft. The wind goes offshore or calm, so the water is clean and pretty, but there's no swell. You'd be floating.
There's another pulse on Monday the 3rd and Tuesday the 4th. Monday morning has a 5ft NW swell with moderate energy, but again, messy cross-onshore wind. Tuesday the 4th brings back the 7ft W swell, but it's onshore. Both days look like a kite surfer's dream and a surfer's frustration with that onshore wind.
Wednesday the 5th of August, the wind finally dies. We get glassy conditions by the afternoon. But the swell has vanished to 1ft. The water temp? About average for the time of year down here. From there, it's a slow, flat grind all the way to the end of the outlook on Monday the 10th of August. Tiny swells and clean wind, but zero power.
Aldinga is known for being inconsistent, and this run proves why. It's a bummer, but it tends not to stay this poor forever. Forecasts can shift. For now? Keep the wax in the wrapper.
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.

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.
