Table - best surf conditions forecast for Cobden Beach - The Channel over the next 16 days.
Alright, this is Rusty, and I’m looking at the next couple of weeks for Cobden Beach - The Channel. It’s a consistent, beginner-friendly spot that’s exposed to the swell, and it likes a WSW direction. The water temp is sitting at 56°, which is pretty much bang on average for this time of year, so nothing unusual there.
The week kicks off with a real tease. Sunday afternoon the 12th looks glassy with a 4ft WSW swell at 15 seconds, and the combined energy is moderate (551). That’s clean, fun-sized surf for a learner. But then things go quiet. Monday the 13th through Tuesday the 14th is a write-off—rain, choppy winds, and poor conditions. We’re looking at a couple of days with nothing to ride.
The real standout comes on Wednesday the 15th. Early morning, it’s glassy with a 10ft W swell, a very long 15-second period, and the energy is strong (4596). That’s a big, powerful groundswell. But here’s the thing: for a beginner spot, this is way too big. This is expert-only territory, and even then, a long-period W swell might be a bit straight at a beach break. It’s a proper sight to see, but only for the experienced crew.
Thursday the 16th is still big, with a 7ft swell early and a 6ft in the afternoon, but the wind is offshore or clean. Still big for the average punter. Friday the 17th is where it gets good for more people. Both morning and afternoon are glassy, with a 6ft to 6ft W swell, solid 13-14 second period. The energy is moderate (1032-1190), and the wind is perfect. That’s excellent, clean surf for competent surfers.
Saturday the 18th and Sunday the 19th are also looking choice. Saturday morning has a 5ft WSW swell, clean offshore winds, and moderate energy (1395). By Saturday afternoon, the swell bumps to 6ft, the period stretches to a very long 17 seconds, and the energy is strong (2187). Sunday morning offers a 5ft WSW at 15 seconds with offshore winds. Afternoon goes glassy with a 5ft W swell. This whole weekend is a solid run of clean, well-shaped waves.
After that, the surf settles down. Monday the 20th through Wednesday the 22nd is smaller, in the 2ft to 4ft range, but with glassy conditions, it’s still fun for the longboard or a learner. It’s consistent, so there’s always something to ride.
The second week sees a little pulse around Thursday the 23rd with a 5ft WSW swell, clean offshore wind, and moderate energy (775), but after that, it trails off into small, cleaner waves for the rest of the period. Nothing huge, but plenty of mellow, glassy conditions.
The best of the whole window is that Friday the 17th, with the glassy, 6-6ft swell and perfect wind. It’s not too big, it’s clean, and the energy is solid. Get on it.
Rusty.
