The Lowdown
Alright, let’s break this down.
Honestly, mate, it’s a grim stretch ahead. We’ve got a solid run of tiny, choppy, onshore slop with nothing worth paddling out for. The first proper recommendation doesn’t even show up until Monday the 27th of July, and even that’s got some serious issues. That’s a week of flat or close-to-flat conditions before we get a look.
So, let’s talk about Aldinga Beach. It’s an inconsistent spot, pretty exposed to the southwest swell window. Water temp is sitting at 58°, which is pretty standard for this time of year – no weird anomaly, just normal winter water. The only real window of opportunity is Monday morning the 27th. We see a pulse of WNW swell push in, around 6 ft with a 6-second period. The combined energy reads moderate (230), and with a light N breeze (10 km/h) blowing cross-offshore, it’s actually clean. That’s your standout, but it’s a short-lived window – beginner surfers might find that 6 ft a bit too much push, so this is more for the intermediate crew. Swell direction (WNW) is a touch west of the optimum SW, but with that clean wind, it’ll still produce some rideable lines.
By Monday afternoon, the wind swings NW and cranks to 22 mph, making a mess with fresh cross-shore chop. From there, the rest of the run is cross-on and lumpy right through to the end of July. Into early August, it’s flat – zero energy on the Saturday, and only tiny pulses after. There's a flicker on Wednesday the 5th of August with a tiny 0.3 ft groundswell from the SW with a 13-second period. The period is long, but at that size, it’s barely a ripple – only a longboard or a foil would get any love.
Bottom line: don’t hold your breath. If you’re keen, the Monday the 27th morning session is the closest thing to a winner we’ve got.

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.
