The Lowdown
Alright, Rusty here again. Aldinga Beach is looking flat as a pancake for the next couple of weeks. The swell’s barely a whisper, with combined wave energy stuck in the weak range – mostly single or low double digits. On Saturday the 12th, you’ve got a tiny 0.3ft SW groundswell with a very long 15-second period, but it’s so small it’s barely a ripple, energy at just 8. Water temp is 58°, which is about normal for this time of year. Not much to get excited about.
The best of a bad bunch is Sunday the 13th afternoon, when a 3ft WNW swell shows up, but it’s onshore at 15 mph from the W, so it’ll be chopped up. The morning is cleaner with a 0.3ft and NNE cross-off at 15 mph, but still tiny. Monday the 14th gives 2ft to 2ft from the W, again onshore. The rest of the week sees mostly 0.7ft to 1ft, with clean offshore winds on the 17th morning (E 6 mph) and 22nd morning (E 12 mph), but the swell just isn’t there. You’ll get a glassy 0.3ft on the 24th and 25th afternoons – barely a bump.
Saturday the 26th morning offers a 2ft SSE windswell at a short 3 seconds, clean with ESE 6 mph, but it’s not going to set the world on fire. After that, it’s flat again. This spot is inconsistent, and this run is typical of the area. If you’re looking to paddle, you might be waiting a while. Maybe the kite crowd will have fun on the windier days. Forecasts can change, but right now, it’s a snooze.

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.
