Table - best surf conditions forecast for Aldinga Beach over the next 16 days.
Alright, gents, Rusty here with the lowdown in old-school numbers. The next two weeks are a tough slog for surfers on this stretch. We’re looking at a long, flat, and blown-out period, with just one late-blooming hope right at the end of the 16-day window.
First up, the grim stuff. From today all the way through to the 25th of July, it’s basically a desert. We’ve got over a week of tiny or messy surf. The wave energy is laughable, with most readings under 100 (mostly in the single digits). That 50 km/h near-gale from the WSW on Saturday the 11th is going to tear up the 8ft swell, leaving nothing but a washing machine. The water temp at Aldinga Beach is 58°, which is a bit cooler than usual for July, but that’s the least of your worries.
We do get a glass-off on the 15th and 16th, but the swell is a joke – a foot or less. The energy is tiny (12 and 6). It’s a pretty morning, but not a surfable one.
Keep your eyes on the 26th of July. That’s the one. The morning of the 26th looks promising with a 5 km/h offshore breeze from the NE and a 7ft swell from the WNW. The combined energy is a solid 346, and the wind is clean. By the afternoon, it really cranks up. The wind goes glassy, and the swell jumps to a proper 10ft from the WSW. The energy hits 857, which is a serious number. This is your only real shot. It’s a long way out, so take it with a grain of salt, but it’s the only thing on the charts that has any life. That 10ft wave is for experienced surfers only, and the 7-second period will make it a bit steep and punchy, but it’ll be a thousand times better than the flat spell we’re in for.
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.
