The Lowdown
Alright mate, Rusty here. Let’s have a look at what’s on the cards for Cudmirrah Reef.
We’re kicking off a pretty quiet run, honestly. The first week or so is mostly small and ordinary, with a lot of those days just not worth paddling out for. There’s a bit of a gap in real quality early on, but things start to look up around the 4th of September and then really get interesting mid-month.
The standout session is definitely the morning of Thursday, 10th September. We’ve got a solid 6ft south swell rolling in with a period of 11 seconds, and the wind is dead calm – glassy as. That’s going to be proper clean, with moderate wave energy (785). The swell direction is right on the money from the south, which is spot on for this reef. This is the one to circle. It’s going to be a bit of a wait for it, but it’s worth it.
Before that, Tuesday morning, 1st September, is a nice little window. We’ve got a 3ft south swell, 11-second period, with a gentle offshore from the NNW. Clean conditions there, and the energy is moderate (202). The water temp is sitting at 62°, which is pretty average for this time of year, so no surprises there.
The big one to watch is Wednesday morning, 9th September. A big 12ft SSW swell hits, with a massive energy reading of 3888, but the wind is a light cross-onshore and the period is 11 seconds. That’s a lot of water moving, and it’s going to be a heavy, powerful groundswell. Given the size and the reef setup, this is strictly for the advanced crew only. The cross-onshore wind will put some bump on it, so it’s not going to be the cleanest, but for the experienced, there’ll be some serious lumps.
The rest of the time it’s mainly small, under 3ft, with a lot of cross and onshore winds, and low energy. The run from the 5th to the 8th is pretty dead, with only tiny, weak waves and poor conditions. The 12th and 13th aren’t offering much either.
So, bottom line: the 10th of September morning is your best bet by a long shot. The 9th is for the brave, and the 1st is a solid, clean small-wave option. The rest is a bit of a write-off.
Rusty.
