The Lowdown

Alright, Rusty here. Let’s have a look at what’s coming our way over the next couple of weeks, focusing on one spot.

We’re starting with a bit of a slow period right now. It’s going to be a few days of pretty ordinary conditions, nothing worth paddling out for in a hurry. The first session that’s actually worth mentioning is on the morning of Tuesday the 15th of September at Cudmirrah Reef. It’s glassy with a light Slight air, small 3ft swell from the northeast. The wave energy is weak (122), so it’s not going to be pumping, but clean. The water temp is 64°, about a touch warmer than normal for this time of year.

The Monday the 14th has some clean-looking bumps at 2ft and 4ft, but the energy is just too low to get excited about. That stretch from the 12th through to the afternoon of the 17th is mostly a write-off with poor to marginal conditions, often onshore or choppy. Not worth your time.

Now, the standout is shaping up for Friday the 18th of September. This is the one to circle. Cudmirrah Reef gets a solid morning with a 4ft swell from the east-southeast, and best of all, the wind goes dead calm – glassy conditions. The swell period is a nice 10 seconds, giving it some shape. Combined wave energy sits at 471 (moderate), so there’s enough push for a decent session on this reef. The optimum swell direction for this break is southeast, and this has a strong easterly component, so it’s not perfect but still very workable. Crowds can sometimes show up here, so expect a few out.

The morning of Saturday the 19th of September is another glassy one with a 3ft swell from the east-southeast and an even longer 11-second period. That’s a bit more of a groundswell feel, which reef breaks love. Energy is still moderate (339). Another clean, fun option.

Later on, around the 22nd and 23rd, things get a bit bigger but messier. The morning of Tuesday the 22nd shows a big 12ft southerly swell, but it’s cross-onshore with wind. That’s big and lumpy – expert territory, and not clean. The energy hits 2031 (very strong), but the wind kills the quality for paddle surfing. Later that week, the morning of Wednesday the 23rd offers a cleaner 4ft southerly swell with a light cross-offshore breeze. A decent option if you missed the main windows.

All up, the best days are the 18th and 19th with clean, waist-to-chest high waves and glassy mornings. Don’t sleep on that Friday the 18th – that’s your winner.

Rusty.

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.
