The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Aldinga Beach. I’ll be straight with you – this 16-day window is lean. Real lean. We’re starting with absolutely nothing on offer, and the only place to look at is Aldinga Beach itself.
The whole 16-day stretch is a flat spell, with no good surf. The first few days are a total write-off. Thursday the 3rd has a tiny 2 ft, 5-second windswell out of the WSW, but with a strong onshore wind, it’s a messy, blown-out situation. Friday the 4th is even smaller at 1 ft, with clean conditions but no real energy. Saturday the 5th sees a jump in size – 8 ft from the WSW on Saturday morning – but the period is only 7 seconds and it’s blowing 25 mph onshore. That’s not surf, that’s a washing machine. The combined energy hits 548 (moderate) but it’s all useless for a paddle.
The combo of significant swell, poor surf quality, and strong wind makes this setup look more interesting for kite surfing than paddle surfing. There’s just no window where the wind, swell, and tide line up.
From Sunday the 6th right through to the end of the period on the 18th, the swell drops to 1 ft and below. Periods hover between 9 and 13 seconds, which is nice for a groundswell, but the height is so small there’s nothing to ride. The combined energy barely gets into double digits, often sitting in the single digits – weak as weak can be. On Tuesday the 8th, we get a glassy morning, but the swell is a pathetic 0.3 ft. The water temp is 58°F, which is about average for the time of year (0.7°F anomaly), nothing unusual there.
To be honest, Aldinga Beach is an inconsistent spot, and this is a perfect example of a blank run. It’s not unusual for this area to go quiet for a while. Forecasts can change, but for now, there’s not a single standout. No calls to make, no waves to chase.
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.
