The Lowdown
G'day, Rusty here, checkin' in from the South Coast. Look, I'm gonna level with ya, the forecast for the next 16 days is a bit of a struggle. We've got a whole lot of nothin' happenin' for a long stretch. The surf is practically non-existent for the first week and a half, with zero-sized dribbles and poor conditions almost every day. It's a real drought, and this kind of blank run is pretty normal for the area when the swell windows don't line up. We're talkin' a solid 12 days of tiny, unrideable junk before we even see a pulse. The only decent spell to keep an eye on, and it's a bit of a wait, comes around the 23rd of September.
Alright, let's try to find a silver lining. The only real standout in this whole 16-day window is a very late one. On Wednesday, September 23rd, Aldinga Beach might finally wake up. The swell is set to jump to 5ft from the West, with a weak period of 6 seconds. The combined energy will be moderate at 154. The water temp is about 58°, which is pretty average for this time of year. The wind is set to be onshore from the WSW, so it won't be perfect, but the raw size is the biggest we've seen by a mile. This bump is really only for the experienced crew, as it'll be too big for beginners. It's a beach break, so with that short-period swell, it might be a bit of a mess, but it's the only shot we've got for a proper wave.
Before that, there's a tiny bit of hope on the 18th of September. The afternoon shows a 4ft swell from the NW, but with a cranky cross-shore wind and a rough chop, it's a real gamble. The combined energy is only weak at 60. Probably more of a kite surfing session than a paddle surfin' one, to be honest.
So, the call is: be patient. The first 12 days are a write-off, but that late-September pulse is somethin' to pencil in. Keep an eye on the wind, and if it swings more offshore, we could be in for a treat.
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.
