The Lowdown

G'day, Rusty here, and I've gotta be straight with ya – the next couple of weeks at Cobden Beach - The Channel are gonna be a wild ride. We're looking at a classic setup of a long period groundswell that's just gonna be way too big for the break for a solid stretch, so you'll be sitting on the beach watching the closeouts more than surfing. The water's sitting at 55°F and is about average for the time of year. The combined wave energy is going to be massive, hitting values like 5995 and 6395, which is some serious power in the water.

The first real chance of getting a wave in starts Saturday the 7th of September. Even then, it's not what you'd call pumping. Monday morning the 7th sees the swell drop to 5ft from the WSW, but it's wrapped in a fresh 19 mph cross-offshore wind from the east, which is keeping things clean. The energy is still moderate at 1206. Monday afternoon is even smaller at 4ft, and the same clean conditions. Tuesday the 8th is a bit of a flat day with 4ft from the NNW and a short period of 9 seconds, energy is down to 419, so it's a bit weak.

Now, there's a real standout if you're patient. Wednesday the 9th of September is the pick of the first week. We've got 3ft of clean swell from the west, but the real magic is the wind – it's glassy, dead calm. The wave energy is low at 265, but you'll be out there with nobody else, enjoying a proper glass-off session. It's a break for beginners anyway, so this is the perfect time to learn.

The second week is a write-off, to be honest. From Thursday the 10th onward, the swell jumps back up to 10ft and higher, with a short period of 8-9 seconds, making it choppy and messy. The energy is moderate to strong (1900-3056), but the wind is all over the place, mostly cross-shore and lumpy. It's simply too big and too onshore for this spot.

There is a glimmer of hope on Tuesday the 15th of September. The morning shows 6ft from the west, and again, glassy conditions. The energy is moderate at 1022, and the forecast says excellent conditions for experienced surfers, but the swell is a bit much for beginners. The session looks promising.

The final chance in this window is on Sunday the 20th of September. The morning has 5ft from the WSW with a nice 14-second period, and the wind is a light cross-offshore from the east, cleaning it up nicely. The energy is moderate at 760. The afternoon is similar with 5ft but a lighter offshore from the SE, and energy at 661. Both are clean and look like good, solid, fun waves.

So, to wrap it up: the true standouts are the glassy morning of Wednesday the 9th for a quiet, clean session, and the clean conditions on Sunday the 20th for a more substantial wave. The rest of the time, you're either looking at flat spells or a massive, messy swell that's just too big for the channel. The crowds are rare here, so if you time it right, you'll have it all to yourself.

Rusty.
