The Lowdown
G’day, Rusty here, and I’ve got the outlook for Cobden Beach – The Channel. It’s a consistent beginner-friendly spot, exposed to the swell, and the optimum swell comes from the WSW. The water temp is about average for this time of year.
Right now, the whole 16-day window is a bit of a wild ride. For the first couple of weeks, the swell is just too big for this break to be any good for a paddle. We’re looking at a solid run of swell that’s consistently over 8ft, making it expert-only at best, and honestly, with the wind often cross or cross-onshore, it’s going to be lumpy and messy. The combined energy of all swells directed here is strong to very strong, with values ranging from 1567 to 8545, so there’s a lot of power moving around, but not in our favour for a clean session.
The first real standout doesn’t come until Sunday the 13th of September. That morning, we’ve got a 3ft swell from the WSW, with a very long period of 16 seconds. That’s proper groundswell, and with a glassy, clean surface and a light breeze, it’s going to be a magic window. The combined energy is moderate at 803, and it’s the only time in the whole run where the conditions are rated as “very good.” This is the one to aim for—a rare, clean, surfable wave for a beginner-friendly break. Keep in mind, because it’s a long-period swell and a beach break, the waves might be a bit straight and more challenging to find a good pocket, but with the offshore wind, it’ll be worth it.
The rest of the forecast is a long gap of blown-out, oversized, or just poor surf. From the start of the period right through to the 12th of September, it’s mostly a write-off—either too big, too windy, or both. There’s a brief moment on the morning of the 6th (Sunday) where the swell drops to 6ft, but the wind is cross and the wave state is marginal, so it’s not a standout.
The week after that standout on the 13th, things go back to being poor. The 14th of September is a Monday morning with a 4ft, 15-second swell, but it’s cross-shore with a cross-chop, so it’s no good.
So, bottom line: if you’re a beginner looking for a safe paddle, wait for the morning of the 13th—it’s the only true highlight. Everything else is either too big, too windy, or both. This is a consistent break, so it won’t stay poor forever, but this run is a long one.
Rusty.
