The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Aldinga Beach over the next couple of weeks.
To be straight with you, the outlook is a quiet one. We’ve got a long stretch of days ahead with next to nothing in the water. The first real chance of a wave doesn’t turn up until the morning of the 28th, and even then, it’s not a pretty picture. The early part of the week is mostly flat or tiny, with a bit of a pulse coming through on Tuesday the 28th that brings a 4ft swell from the west, but it’s arriving with a messy onshore wind and a period of just 5 seconds. That’s short-period, wind-driven junk, and combined wave energy is only moderate at 112. It’s not a session you’d paddle out for on a surfboard – the wind and chop would make it more of a kite session.
After that, we’ve got a few days of small, weak swells, mostly under 3ft, and the wind is often onshore or gusty, keeping the surface lumpy. The morning of the 30th does offer a glassy spell with a tiny 1ft swell from the WSW, but with only 11 energy, it’s barely a ripple. The rest of the first week and into the second week is a long run of flat-to-miniscule surf, with combined energy values often sitting at 1–4. That’s about as weak as it gets.
Looking further ahead, the morning of the 7th of August shows a long-period groundswell pulse from the southwest, with a period of 15 seconds, but the swell height is only 0.3ft. That’s a lot of energy for nothing to ride. The 8th of August is similar, with a 0.3ft, 14-second swell from the southwest. It’s a tease, but there’s no size to work with. The wind stays light and cross-off for those days, so the conditions would be clean if there was any wave.
Overall, there’s no standout session. The best of a very poor bunch would be the morning of the 30th of July, where the glassy conditions and a tiny 1ft swell from the WSW might offer a rare, super-small longboard cruise if you’re desperate. It’s not worth getting excited about. The rest of the 16-day window is a write-off for any decent surf. The water temperature is around 57°, about 1° cooler than average for this time of year, so it’s a little chilly but nothing out of the ordinary.
Stay patient, lads. It’s a flat spell.
Rusty.

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.
