The Lowdown

G’day, it’s Rusty here. Let’s be straight with you: this stretch of coast is looking pretty flat and underwhelming for the next couple of weeks. We’ve got a long run of poor surf ahead, and there’s nothing that’s going to get your heart pumping just yet. The first week is basically a write-off, with tiny, weak leftovers barely showing their faces. We don’t see any proper swell until around the 21st, and even then, it’s ordinary at best. There’s a glimmer of something a touch more interesting right at the end of the window on the 26th, but I wouldn’t book the day off work for it just yet.

The water temp at Aldinga Beach is sitting at about 57.9°F, which is about normal for this time of year, so nothing weird there.

We start the whole run on Friday the 11th with a poor little 0.3ft west swell, and the energy is basically non-existent (1). It stays that way for days – a mix of tiny 0.3ft and 0.7ft waves, often with short periods that don't have any grunt. There’s a slight bump on Sunday the 13th with a 3.3ft west swell, but it’s short period (4 seconds) and the wind is blowing 30 km/h from the west, making it lumpy and cross-onshore. Not worth getting wet for.

Through the middle of the week, we see 2.3ft to 2.6ft swells, but they’re all short-period wind slop from the west or southwest, and the winds are all over the shop – cross-onshore, cross-shore – leaving the surface messy. The energy readings stay weak, in the 24 to 32 range. There’s a clean window on the morning of Monday the 15th with light offshore winds, but the swell is only 2.6ft and weak, so it’s just ankle-biters.

The gap of genuinely poor, unsurfable conditions stretches right through until the 20th. On the 21st, we finally see the energy levels climb into the moderate range (60, then 141 on Monday afternoon) with a 3.6ft to 4.9ft west swell. But it’s all onshore and messy, so it’s going to be a blown-out, ugly sea. That’s more of a look for the kite surfers than a paddle surfer.

The 22nd backs right off again, and we’re back to tiny, weak waves. We get a few clean and glassy mornings in there, but with practically no swell, it’s just a flat, pretty ocean.

The only real standout of the entire window shows late on Saturday the 26th. That afternoon we see the summary swell jump to 5.2ft from the west-southwest, and, crucially, the wind is forecast to be glassy – just 5 km/h. The energy vaults up to 171, which is a solid, moderate pulse. Aldinga Beach, with that southwest swell and clean conditions, is finally going to have some proper lines. It’s not huge, but it’ll be clean and that counts for a lot. Given the forecast is well over a week out, treat it as promising but not set in stone. The long period is still a bit of a factor at a beach, but with glassy conditions, it'll be worth a look.

Overall, it’s a long, flat slog with one potentially decent afternoon right at the end of the run. Keep your expectations low for the next week and a half, and maybe start getting a little more interested as we approach the 26th.

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.
