The Lowdown
G’day, it’s Rusty.
Honestly, the next couple of weeks are looking pretty ordinary for Aldinga Beach. We’ve got a long stretch of tiny, weak surf, and you’ll be waiting over a week for anything that even gets close to rideable. The swell energy is just nowhere near enough to get things moving.
Right now, through the 11th, we’re looking at ankle-biters around 0.3ft with weak energy readings in the low single digits. There’s a bit of glassy action on the Friday afternoon, but with zero wave power, it’s flat. This run of nothing continues right through to the 23rd, with most days offering barely a ripple and energy values mostly below 20. There are a few slightly cleaner windows with light offshore breezes, but the swell just isn’t there. The periods are short, mostly under 10 seconds, so there’s no push or shape to speak of.
Now, there is a glimmer of hope at the very end of the window. On the 24th, the swell finally shows a pulse, jumping up to 4ft from the west with a period of 6 seconds, and the energy reading climbs to 98 (moderate). But that short period and a light cross-onshore breeze mean it’ll be pretty lumpy and unorganised. It’s not worth getting excited about, and it’s too far out to call. It might be the best of a bad bunch, but for Aldinga, this is a pretty bleak outlook. The water temp is sitting around 59°, which is about average for this time of year.
Given how small and weak it is, and with that onshore wind forecast for the 24th, this setup looks more interesting for a kite than a paddle board. Keep an eye on the charts, but don’t hold your breath for any gems in this run.
Catch you down the beach.

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.
