The Lowdown
Alright folks, Rusty here. Let’s get real about what’s coming down the pipe for Aldinga Beach over the next couple of weeks. I’m gonna be straight with you: this is going to be a tough stretch for paddle surfing. The reliable swells just aren’t lining up, so don’t get your hopes up too high for any classic sessions.
Looking at the whole 16-day window, we’ve got a massive gap of quiet, tiny surf right from the start. The first real pulse of energy that’s worth talking about doesn't show up until September 5th, and even then, the conditions are a mess. That’s over a week of flatness or ankle-biters from August 26th through September 4th. You’ll see a few days early on with glassy conditions on Wednesday morning August 26th or Friday morning August 28th, but with swell heights stuck at 0.3ft to 0.7ft, you’re just staring at a lake. Wind is light or glassy, sure, but there’s nothing to ride.
The pattern finally shifts around September 5th. On Saturday afternoon September 5th, the swell bumps up to 4ft from the West, with a combined energy of 64 (moderate). The trouble is, the wind is howling onshore from the W at 16 mph, which is going to chop it up bad. The period is a short 5 seconds, so it’s messy, wind-driven slop. Sunday September 6th keeps the West swell around 3ft with that same short 5-second period, but the wind backs off to a light onshore. It’s still not clean. This whole setup at Aldinga, being a fairly exposed beach break, looks a lot more interesting for kite surfing than paddle surfing through this period.
Then, we get a stand-out possibility on Thursday morning, September 10th. The swell jumps to 8ft from the WSW with a combined energy of 671 (very strong). That’s a proper swell. The wind is howling offshore from the N at 16 mph. Sounds perfect, right? Well, hold up. That 8ft is only for experts, and it’s coupled with a short 7-second period. At a beach break like Aldinga, a short-period, powerful swell like that can be a chaotic, walled-up mess. It gets a marginal score, so I’d call it a raw, powerful day for very experienced crew only. The preceding morning, Wednesday September 9th, also shows promise with a 4ft West swell and clean offshore winds from the N at 12 mph, but again the period is a weak 6 seconds, so the energy is there but the shape won't be classic.
As for the water, it’s about 58°F which is normal for the time of year, so no surprises there in terms of warmth.
To sum it up: there is no "best on offer" that I’d confidently recommend for the average surfer. The only window for a true standout is that big 8ft day on September 10th, but it’s only for experts and the short period is a major caveat. The rest is a long wait for small, onshore, or poor-quality waves. If you’re desperate, keep an eye on September 9th for a chance at a clean but weak wave.
Stay patient, and keep checking in.
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.
