The Lowdown
Alright, Rusty here, and I’m calling it as I see it – this stretch is flat-out quiet. There’s nothing doing for the first week and even into the second, we’re barely scratching together anything rideable.
For the first few days, it’s all tiny stuff, 0.3ft max, with combined swell energy numbers that are just sad (from 4 up to 10). The wind cleans up on a couple of mornings – like a glassy northwest breeze on Tuesday the 8th, and a clean offshore southeast breeze on Wednesday the 9th – but without any swell, it’s just a pretty, flat ocean. This is a long, boring run.
Come the second week, Sunday the 13th shows a little northerly bump at 2.6ft, but with a period of just 4 seconds and a combined energy of 29. It’s weak and choppy with a moderate cross-shore wind. Not worth getting wet for.
Your one real window, and it’s still not much, is Tuesday the 22nd of September at Triggs Beach Adelaide. A north swell pushes through at 4ft, period of 5 seconds, and combined energy hits 76 – the biggest number in the whole forecast. The morning wind is a clean cross-offshore from the north-northeast. It’ll be the best of a poor bunch, but that short period means it won’t be well-shaped. Water temp is around 58°, which is about average for this time of year.
If you’ve got to surf, aim for that Tuesday morning. Otherwise, it’s a long wait for nothing much.
