The Lowdown
Alright folks, Rusty here. Gotta be straight with you – the next couple of weeks look pretty grim for a paddle around Aldinga Beach. We’re looking at a big, fat gap with no real surf to speak of. The whole 16-day window is basically a write-off for any decent waves.
We start off the 21st of July with tiny, knee-high slop at 0.7ft from the WSW with a short 9-second period, and that’s as good as it gets for a while. The wind is all over the shop, but the swell is just too weak to care. The combined energy is a measly 14, so don’t even bother.
We’ve got a stretch from the 21st right through to the morning of the 27th of July where the finder gives us nothing but zeros. That’s a solid six-day blank run. The water temp is sitting at 58°, which is about normal for this time of year, so nothing wild there.
Then on the 27th of July, Monday morning, there’s a little flicker of hope. The swell bumps up to 5ft from the WNW, but the period is a short, crumbly 5 seconds, making it weak and messy. The combined energy is still only 94, so it’s weak. The morning is glassy, which is a treat, but the waves are labelled as “very ordinary conditions.” It’s surfable if you’re desperate, but it’s not what I’d call a good session. The wind goes onshore later in the day, so that window is tight.
After that, it’s back to the same old story. The rest of the period is filled with tiny dribbles, flat spells, and onshore winds. The only thing worth noting is a couple of mornings with glassy conditions and clean offshore winds, but there’s simply no swell to ride. The swell direction is generally WSW to SW, which is fine for the spot, but the waves just aren’t there.
This is one of those stretches where the area just goes to sleep. It happens. Don’t stress, forecasts can change, but right now, leave the board in the shed.
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.
