The Lowdown
Well, mate, I'm Rusty, and I’ve gotta be straight with you – it’s a tough stretch ahead for Aldinga Beach. The whole 16-day window is a write-off for any decent surf. There’s a massive gap from the start right through to the end, with barely a ripple worth paddling for.
The first few days, starting Thursday 30 July, are flat. We’re talking tiny 1.0ft dribbles from the WSW with a weak period of 7 seconds and barely any energy (11). The water is sitting at 58°F, which is pretty much normal for this time of year, so no surprises there. The winds are glassy and calm, but there’s nothing to ride.
Friday and the weekend stay just as flat. Winds flip around but the swell stays tiny, under 0.7ft, with energy levels dropping to just 1. It’s all hopelessly small.
Then Sunday 2 August afternoon sees a bit of a pulse – 4ft from the WNW, but it’s a short-period 5-second windswell with only 59 units of energy. The wind is a messy cross-onshore at 30 km/h, making it lumpy and poor. Not worth a look.
The following week is more of the same: tiny, weak, and often blown out. The wind stays onshore or cross-off, but the swell never gets above 2ft. Even the mornings that are clean have no wave to ride.
Heading into the second week, there’s a spike on Sunday 9 August with 5ft from the WNW and 130 energy, but it’s accompanied by 30 km/h winds and rain. It’s still poor surf. Then Monday 10 August sees a bigger 8ft to 8ft WSW swell with 527 to 635 energy – that’s a lot of power, but it’s howling onshore at 35 to 50 km/h. That’s not surf, that’s a washing machine. For experts only, if anyone’s mad enough.
The rest of the week dies back down to nothing. By Friday 14 August, it’s back to 0.3ft and clean offshore winds, but there’s nothing to catch.
So, the honest truth? There’s not a single standout day in the whole 16-day forecast. No good options. It’s a long, flat run with no surf to speak of. For a spot that’s inconsistent at the best of times, this blank run is pretty normal. Keep the board in the shed, wait for the forecasts to change.

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.

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.
