The Lowdown
Alright folks, Rusty here. Let’s get stuck into what’s cooking for the next couple of weeks.
To be honest, the start of this run is a bit of a write-off. We’ve got a decent push of southerly swell, but it’s arriving with some nasty cross-onshore wind that’s just gonna chop everything up. For the first few days, you’re better off staying home.
The real action, and the standout of the whole forecast, looks to be shaping up for Friday morning, September 16th, at Cudmirrah Reef. It’s a solid, consistent reef break that takes a fair bit of swell to get going. On that morning we’re looking at a clean 6 ft south swell with a period of 11 seconds, so there’s some proper groundswell energy in the water. The wind is light and cross-offshore, which is gonna keep those faces nice and clean. This is a spot for the advanced crew, and with those conditions, it’s the best on offer for the whole outlook. The water temp is nothing unusual for the time of year.
Before that, we do have a glimmer of hope. Friday morning, September 11th is worth a mention. The sun is out, the wind is glassy, and we’ve got a 5 ft south swell. The energy is moderate, but that glassy surface will make for some fun, clean waves. It’s a small window of quality before the wind switches again.
After that September 16th morning, the consistency drops off. There’s a few bits and pieces, like a 5 ft south swell on the afternoon of September 19th with a clean look, but nothing that matches the quality of that Friday peak. The long period 18-second swell on September 18th is tiny at 1 ft, so it’s all show and no go. By the end of the run, around September 21st, we get a clean 6 ft south swell that looks promising, but that’s over a week away and a bit of a long shot.
So, to sum it up: the first few days are a mess. Friday the 11th gives you a clean, glassy session. Friday the 16th is the only real standout – get in the water if you're an advanced surfer and can handle a proper reef. After that, it’s a waiting game.
Rusty.
