The Lowdown
Alright, let’s break it down.
It’s gonna be a lean couple of weeks at Aldinga Beach. Honestly, for the first week, there’s nothing to talk about. The swell is tiny, the wind is all wrong, and the wave energy is just pitiful. You’d be better off cleaning your board.
The first half-decent chance doesn’t roll in until Monday the 14th of September. Monday afternoon brings a bump to about 7ft from the west, but the period is a short, choppy 6 seconds. The wind is light and cross-shore, so it won’t be a total mess, but it’s still only marginal. The wave energy hits a moderate 318, so there’s some power there, but the quality is lacking.
Tuesday the 15th sees a bit more size – about 5ft in the morning from the west-southwest – but with a fresh 35 km/h cross-shore wind from the south-southeast, it’ll be lumpy and ugly. The energy is moderate at 190, but conditions are poor.
The only real highlight, and I’m being generous here, is Friday the 18th of September. The swell is small – 2ft to 3ft – but with glassy winds and a little bit of energy (29 in the afternoon), it’ll be clean. Not big, not powerful, but if you’ve got a longboard, you might find a few glassy runners.
Water temp is sitting right around 58°F, which is about normal for the season, so no worries there.
Bottom line: the whole 16-day forecast is a dud. Aldinga is an inconsistent spot, and this run of tiny swell and bad wind is pretty normal for a dry spell. Kite surfers might get a look in on the windier days, but for the rest of us, it’s a waiting game.

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.
