The Lowdown
Alright, folks, Rusty here. Let’s be straight with you. The next couple of weeks are looking pretty bleak for a proper paddle. We’ve got a long stretch of tiny, weak surf ahead, so if you’re jonesing for a wave, you’re gonna have to be patient. There’s a brief pulse of energy mid-window, but it comes with a lot of wind and mess, so we’ll have to see how it shapes up. The good news? It won't stay this flat forever.
Right now, for the next week and a half, it's a waiting game. We're looking at mostly ankle-biters, with the swell hovering around 0.3 ft to 1 ft for days on end. The energy is weak, with values mostly in the single digits to low twenties. The wind is all over the place, sometimes offshore but mostly cross or onshore, so there’s nothing clean or rideable. The water temp is sitting at 58°F, which is about average for this time of year, so at least that’s not a shock to the system when you go for a look.
Things get a little more interesting on Wednesday, August 26th. A big westerly swell is forecast to roll in, with the summary height jumping up to 3 ft in the morning and then a solid 8 ft in the afternoon. The combined energy goes from a weak 35 to a strong 466 in just a few hours. That’s some serious power, but it’s coming with a stormy westerly wind blowing 25 to 40 km/h. This is going to be a messy, blown-out situation. For a beach break like Aldinga, that much west wind and that much swell will just be a washing machine. It’s really only going to be interesting for the kite crew, not for us paddle surfers. If it cleans up, it’s a different story, but right now, I’m not holding my breath.
After that pulse, it fades just as fast. Thursday the 27th drops back to 4 ft but onshore winds keep it junky. By Friday, we're back down to nothing. The rest of the run into September is more of the same – tiny swells and very weak energy. There are a couple of glassy moments on the 23rd and the 1st of September, but with just 0.3 ft to 0.7 ft on offer, it’s not even worth getting the board waxed.
So, bottom line? There is no standout day in the next two weeks. Not one. The only real swell event is the one on the 26th, and it’s completely ruined by wind. If you can, look elsewhere or take up a new hobby for a bit. The surf will come back, it always does, but for now, the forecast is a barren wasteland.
Stay patient.
Rusty.

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.
