The Lowdown

Alright, Rusty here. Let’s have a look at what’s cookin’ for Cudmirrah Reef over the next couple of weeks. It’s a bit of a slow burn, so don’t be in a rush.

We’ve got a few days of small, average energy to sit through. The first bit of surf worth paddling out for shows up on Thursday morning the 3rd of September, but honestly, it’s a pretty weak start. We’re talking a tiny 2ft swell from the south with a period of 10 seconds and a combined energy of just 80. The wind is cross-off from the WNW at 9 mph, which keeps things clean, but the waves are ordinary.

The first real standout comes on Sunday the 6th of September. The morning glass-off is the call. Winds are light from the south, glassy conditions, and the swell bumps up to 4ft from the south with a 9-second period. The combined energy jumps to 364, which is moderate, and the report says expect good surf conditions. That early Sunday session is where you want to be if you’re keen – clean, lined up, and the reef doing its thing. The afternoon on Sunday is a no-go though; the cross-onshore from the ESE at 9 mph chops it right up.

Now, hold on to your board for Thursday the 10th of September. This is the absolute standout of the outlook. We get a solid 6ft swell from the SSE, with a long period of 11 seconds, driving a combined energy of 748 – that’s strong wave energy. And the morning is glassy. There’s a very good chance of cracking waves here. This is groundswell, and it’ll be peeling down the reef beautifully. The afternoon is still fun, but the wind swings cross-on, so the morning is your time.

Friday the 11th of September is still worth a look in the morning. The swell drops a bit to 4ft, still from the SSE, but the period stretches out to a very long 12 seconds (combined energy 423). With a light cross-off breeze from the NNE at 3 mph, it’ll be clean and lined up. Again, the afternoon gets messed up by stronger cross-shore wind.

After that, the energy fades. The second week is pretty quiet. There are a few days like Tuesday the 15th of September with a bump of 3ft but short period, and some poor-to-ordinary conditions. Nothing to get excited about. Expect a long gap from around the 12th right through to the end of the forecast window, with mostly small, weak, or poorly shaped surf. The combined energy drops back to two-digit numbers often, and the period is short, so it’s not really worth the paddle.

So to sum it up: if you can, get out on Sunday the 6th for that glassy morning. But the real gem is Thursday the 10th of September – get there early for the 6ft SSE groundswell with clean, glassy conditions. That’s your best bet by a long stretch.

Rusty.

A general guide to surfing at Cudmirrah Reef can be found by selecting the local surf guide option on the grey menu.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. 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 Cudmirrah Reef 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
