G’day, Rusty here. Look, I’ve gotta be straight with you – it’s a pretty grim run for Aldinga Beach across the whole 16-day window. There’s almost nothing to get excited about, and that first real chance of anything rideable doesn’t show up till the morning of Monday the 21st of July. That’s over a week of flat or messy junk. The water temp is about average for the time of year, so no surprises there, but the lack of swell is the real story.

From now through to Sunday the 20th, it’s a write-off. We’ve got a bit of a pulse on Saturday the 11th with some nasty 6ft swell from the NW and a 6-second period, but the wind’s howling at 28 mph from the NW – pure cross-shore slop. The combined swell energy is a moderate 223, but you wouldn’t want to be out there. Sunday’s not much better. Then the swell dies right off, dropping to tiny 1ft by Wednesday the 15th, but that brief glassy morning there’s just no power. It stays flat for days after.

Then on Monday the 21st of July, things finally wake up a little. The morning brings a 4ft swell from the WSW with a 6-second period, combined energy hitting a weak 104, and the wind is light from the north at 9 mph – clean and cross-offshore. The guide says “surfable waves but very ordinary conditions” and scores it a 1 out of 10. Honestly, that’s your best shot. It’s not big, it’s not long-period, and it’s an inconsistent, fairly exposed beach (Australia) that needs a proper SW swell, so this is just a weak taste. Crowds are often here, so you might see a few others hoping for scraps.

After that, it fades back into tiny dribble. The morning of Tuesday the 22nd is flat, and the rest of the run is all small, choppy, or cross-shore junk. The swell goes negligible by the weekend of the 25th, even though it’s glassy at times – nothing to ride.

So, the standout is that Monday morning on the 21st of July. It’s clean, it’s small but rideable, but with inconsistent conditions and only moderate energy, it’s one for the faithful. Just don’t expect anything special.

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.
