The Lowdown
G’day, Rusty here. Look, I’ve gotta be straight with you – this 16-day window for Aldinga Beach is a tough one. There’s genuinely nothing good on offer for the whole stretch. The forecast is a flat, blown-out mess from start to finish, with not a single moment where the stars align for a decent paddle. We’re looking at a solid blank run here, which is more normal for this area when the conditions just don’t cooperate.
Kicking off Monday the 27th of July, we’ve got a tiny 0.2ft to 0.4ft of messy swell from the WSW with a short period of 5 seconds, and the wind is howling from the N and NNW at 16 to 22 mph. That’s a cross-off to cross breeze, but the energy is next to nothing (combined energy of 2 to 13), so it’s flat and frustrating. Tuesday the 28th sees a bit of lift with swell hitting 4ft to 5ft from the W, but the period is still a weak 5-6 seconds, and the wind swings onshore from the W and SW at 19 to 22 mph, making it lumpy and messy – poor surf, no question. Combined energy gets up to 187, but it’s all wind chop.
Wednesday the 29th drops back to 1ft to 2ft with onshore wind, and Thursday the 30th goes flat with a glassy 0.7ft but no power. Friday the 31st through Saturday the 1st of August is almost dead flat with 0.3ft swell and combined energy of just 1 – not worth getting wet. Sunday the 2nd of August shows a pulse of 5ft from the NNW and W, but it’s short period (5 seconds) and the wind is a strong 19 mph cross-off from the N; combined energy hits 113, but the swell is too weak and short to shape up. After that, it’s all downhill again with tiny swell and onshore winds through to the 11th of August, where we finally see a glassy 0.7ft from the WSW with a 9-second period and combined energy of 16, but it’s still flat and lifeless.
Water temperature is about average for this time of year, so no surprises there. Look, there’s no standout, no hidden gem, no day to circle on the calendar. This is a dust-settling period for the ocean. It tends not to stay poor for long, and forecasts can change, so keep an eye on it, but for now, save your energy.

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.

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.
