The Lowdown
Alright, Rusty here. Let’s break down what’s in store for Aldinga Beach over the next couple of weeks.
Straight up, this is a dry spell, no two ways about it. The first week is a total bust. It’s going to be a long, flat, and frustrating stretch with barely a ripple from Wednesday the 29th of July all the way through to late in the week of the 4th of August. We’re talking tiny dribbles of 0.3ft to 1.0ft, mostly from the WSW, with periods around 7 to 8 seconds – that’s just weak, short-period wind slop. The combined swell energy is pitiful, barely hitting double digits (20 or less) most days. There are a couple of glassy mornings, like Thursday the 30th and Friday the 31st, but there’s just no swell to push it. You’d be better off skipping the paddle and enjoying the clear skies from the beach.
Now, if you’re a patient soul, things start to look a bit more interesting, though it’s still not a classic. Keep your eyes on Monday the 10th of August. We’ve got some proper energy swinging in overnight. Monday morning sees the swell jump to a solid 10ft from the WSW with an 8-second period, and the combined swell energy is cranking at 1035 – that’s strong. But the wind is a cross-onshore from the south at 9 mph, making it a messy, choppy beast. By Monday afternoon, the wind drops to a light cross-shore from the SSE, but the size is still a heavy 10ft. That’s expert territory. This is a big, raw ocean that will be closing out most of the beach.
The real standout, or the best of a challenging bunch, comes on Tuesday the 11th of August. The morning is the one to aim for. The swell is still a meaty 7ft from the WSW, but the wind has shifted to a clean offshore from the NE at 9 mph. That’s the magic ingredient. The combined energy is still very strong at 378, and with that offshore wind, Aldinga could actually hold some shape. It’s an inconsistent break as it is, and the period is a short 7 seconds, so the sets won’t be long, but the conditions will be clean and the waves will have some grunt. This is for intermediate to advanced surfers; 7ft is too much for beginners. The afternoon drops to 3ft with a lighter cross-off wind, still clean but with less punch.
The water temperature is sitting around 58°F, which is about 1°F below the long-term average. Nothing unusual, just your typical bone-chilling winter water.
Beyond that, it fades out again quickly. Wednesday the 12th and Thursday the 13th are back to small, weak dribbles. So there it is. A long flat spell, one rough and powerful day for the brave, and one clean, solid morning on the 11th that’s the only real ticket. Don’t hold your breath for anything else.
Rusty.

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.
