The Lowdown
Alright, Rusty here. Let's have a look at what's coming down the pipe for Aldinga Beach.
To be honest, this is a real quiet stretch for the next week and a half. Looking at the whole 16-day window, there's a massive gap right at the start with nothing happening. We're talking almost two weeks of tiny, weak waves that just aren't worth paddling out for. The energy is almost non-existent, with readings like 1 or 2 (it's flat), and the few bumps we get are barely 0.3 ft. It's a bummer, but it's one of those stretches where the ocean just goes to sleep.
The first real glimmer of hope, and I mean *real* hope, doesn't show up until Saturday, August 22nd. We finally see a pulse of swell arrive, but it comes with a price. The wind swings onshore and howls. By the afternoon, we're looking at a 3.9 ft swell from the west, but it's coupled with a nasty 18.6 mph onshore wind. The period is a short, choppy 5 seconds, and the combined energy is a moderate 85. It's going to be a messy, blown-out mess. Honestly, for a beach break like this, with that much wind and that sort of short-period swell, the setup looks more interesting for kite surfing than paddle surfing.
The following morning, Sunday, August 23rd, is a touch bigger at 3.9 ft and a bit more energy (111), but it's still a jumbled up cross-onshore affair. The swell is still short-period (6 seconds), fat and weak. Not a great window for a clean ride.
Keep an eye on Wednesday, August 26th. That's the standout in the whole forecast. The early morning brings a 5.6 ft swell from the west-southwest, with a combined energy of 265 – that's a solid push of water. The period is still short at 7 seconds, so it's going to be a bit sectiony and won't have the long, lined-up walls of a proper groundswell. For a beach break, short-period 5.6 ft surf can be a bit of a washing machine. The winds are onshore, so it's going to be a bit of a battle. This one is really only for the experienced crew; it's too big for beginners. The water temp is sitting at 57.4°, which is bang on average for this time of year, so nothing unusual there.
The rest of the second week cleans up again, but the swell dies right back down to the 1 ft range with glassy conditions, so you're back to a longboard or a flat day.
So, the pick of the litter is that Wednesday, August 26th morning session. It's not perfect, but it's the only time we get any real size and energy. Don't expect a perfect lineup, but if you're after a challenge and a bit of power, that's your window. Everything else is a write-off until then.

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.

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.
