Cudmirrah Reef Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get stuck into what’s coming up for our little stretch of coast at Cudmirrah Reef. It’s a bit of a slow-burner to start, but hold onto your boardies, because there’s a serious pulse of energy on the horizon.

We’re looking at a quiet start right through the first few days. Tuesday, the 1st of September, kicks off with small 3ft south swell and a light offshore breeze, which keeps things clean, but the wave energy is weak (165). It’s surfable, but nothing to write home about. Wednesday and Thursday are much the same story – tiny, clean waves losing height each day, with the swell dropping to 1ft by Thursday afternoon and the energy fading right out (62). Friday morning, the 4th, offers a window of glassy conditions on a small 2ft south swell, but the period is short at 7 seconds, so it’s going to be a bit soft and weak. The weekend is a write-off with poor conditions and strong winds.

We hit a bit of a lull until Monday morning, the 7th of September. That’s when we see a real change. The wind goes glassy, and we’ve got a solid 4ft south swell (10-second period) pumping in with moderate energy (265). The forecast says “expect good surf conditions,” and on a reef like this with glassy winds, that’s a window to grab. The water’s sitting at 63°, which is pretty much bang on average for this time of year, so no drama there.

But the real standout, the one you’ve been waiting for, is Wednesday the 9th through to Friday the 11th. This is the big one. Wednesday afternoon sees a jump to 12ft of south swell, with a 10-second period and massive energy (4170). The wind is offshore and clean. This is for experienced surfers only – at over 8ft, it’s expert territory. Thursday the 10th holds at 10-13ft, all south swell, though the wind turns a bit cross. Still, the energy is enormous (2726).

Then, Friday morning, the 11th of September, is the absolute peak. We’re looking at 12ft of south-southeast swell with a long, powerful 13-second period, offshore wind, and energy readings over 4000. By Friday afternoon, it gets even better: 13ft, 12-second period, glassy winds, and energy hitting a staggering 7191. The guidance calls it “exceptional” for experts. This is a true groundswell, and it’s going to wrap beautifully into Cudmirrah Reef. The long period at a reef break like this is a dream – the waves will be thick, powerful, and well-shaped. Just be aware, with that kind of size, it’s not a beginner's wave. The crowd factor? It says “sometimes,” so expect a few others who’ve been watching the charts.

After that pulse, the swell drops back through the weekend, but Monday the 14th offers a nice little reset with a glassy 4ft south-east swell, a long 11-second period, and solid energy (667). That’s a great, clean morning for the regular crew. The 15th and 16th keep a 5ft to 7ft south swell rolling in with clean conditions, a good way to wind down the run.

So, to sum it up: the first week is small and slow, but the second week is an absolute ripper, with Wednesday the 9th through Friday the 11th being the clear standouts. Get your gear ready.

Rusty.
