The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this outlook is a tough one.
We’re looking at Aldinga Beach, and honestly, for the next couple of weeks, there’s just nothing to get excited about. The entire 16-day window is a flat spell. We’ve got a solid 11-day gap with no real surf to speak of, and what little comes after that is messy and blown out.
The first whisper of something happens on the morning of the 20th of September. A short-period, windswell bumps up to 3 ft from the WSW, but the wind is a strong 25 mph cross-shore from the NNW. That’s going to be a mess of chop and cross-chop. The combined energy is only moderate (60). Not a paddle-surf day – that setup looks more interesting for kite surfing than anything else.
The afternoon of the 23rd of September sees the biggest swell of the period, hitting 5 ft from the WSW. But the period is a weak 5 seconds, and it’s blowing straight onshore from the W at 12 mph. The energy jumps to moderate (106), but with that wind, it’s just a choppy, blown-out lump. Not for the faint-hearted, and definitely not for beginners – that’s getting into expert territory for the poor conditions.
The best of a bad lot might be the morning of the 24th of September. Swell drops to 4 ft from the SW with a 6-second period, and the wind is a gentler cross-shore from the S at 9 mph. The energy is moderate (90). It’s still not great, but it’s the least ugly of the bunch. Still, with the short period and consistent cross-shore, the waves will be bumpy and hard to ride.
So, what’s the call? There are no standouts. No hidden gems. This is a blank run for the area, and it’s one of those times where you just have to wait. The drought is real, and there’s nothing to chase.
Stay patient, and keep an eye on the charts. Things can change.
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.
