Updates in hr min s Forecast update imminent
Alright folks, Rusty here, and we’re dialing into a spot that’s got a real split personality for the next couple of weeks. The Channel at Cobden Beach (Cobden-Beach) is the only game in town, and it’s a tale of two extremes – some magic windows, and some absolute monsters that you’ll want to watch from the sand.
Right off the bat, Monday the 6th is a no-go. The swell is a solid 8 ft from the West, but the combined wave energy is huge (2991), and the forecast straight up says it’s too big for this break. Don’t even think about it.
The real sweet spot kicks off Tuesday morning the 7th. We’re looking at a clean 5 ft West-southwest swell with a nice 14-second period. The wind is gentle and offshore from the SSE, so expect some long, clean lines. The energy is solid (767), and the conditions are set for a cracking session. This is your standout. That afternoon the swell drops to 3 ft, still good and offshore, with energy at 439.
Wednesday the 8th keeps the good times rolling. We’ve got a morning session with a 3 ft West-southwest swell (energy 325) under a light offshore ESE breeze. It’s small but clean. The afternoon picks up a bit to 5 ft from the West (710), but the wind picks up to a moderate breeze – still offshore, so still workable.
Thursday the 9th is a day for the experienced crew. The morning brings a meaty 6 ft West-southwest swell (1293) with a 14-second period and gentle offshore wind. The afternoon stays solid at 5 ft (1261) with a moderate offshore breeze. This is fantastic, powerful surf for those who know what they’re doing.
Friday the 10th is possibly the pick of the first week. The morning has a 3 ft West-southwest swell (625) with a very long 16-second period, and a clean cross-offshore breeze. But the afternoon... oh, the afternoon. The wind goes glassy at 5 km/h from the SE, with a 4 ft swell (628) and that beautiful 16-second period. It’s going to be smooth as silk.
Saturday the 11th is another treat. Glassy conditions in the afternoon with a 4 ft West-southwest swell (774) and a 16-second period. The morning is clean too with a 3 ft swell and a light cross-offshore breeze. Sunday the 12th is similar, with clean 3-4 ft surf, but a little more breeze. It’s still fun, but the magic is fading.
Things go a bit sideways on Monday the 13th. The swell drops to 2 ft and the wind turns onshore, creating choppy conditions. This run of poor surf continues through Tuesday the 14th with strong, messy onshore wind and a sloppy 8 ft north-northwest windswell. Not worth a paddle.
Now, here’s where it gets interesting again. Wednesday the 15th is for experts only. The swell jumps to a massive 10 ft in the morning (3636) and a huge 12 ft in the afternoon (6667) from the West. The winds are light and offshore in the morning, and glassy in the afternoon, but the forecast is clear: this is too big for this break. Same story for Thursday the 16th (8-8 ft, 2153-2487) and Friday the 17th (12 ft, 3267-5596) – these are massive, powerful swells that will be closing out and dangerous. Only the most experienced chargers should even look at these days.
The surf finally drops back to manageable levels on Saturday the 18th. The morning brings a clean 6 ft West swell (1216) with a 13-second period and light offshore wind. That’s a solid, clean session for the experienced crew. The afternoon turns onshore and messy, so don’t bother.
The last few days, Sunday the 19th through Monday the 20th, wind down with clean, smaller surf in the 3-4 ft range. A good way to finish the run, but nothing huge.
To sum it up: Your absolute standout is Friday the 10th afternoon. Glassy conditions, a 4 ft West-southwest groundswell with a 16-second period – that’s the sort of session you wait all winter for. The morning of Saturday the 18th is also a good bet for the experienced surfer when the giant swell finally backs off. Most of the big stuff from the 15th to the 17th is just too much for the channel to handle.
Stay safe, keep your wits about you, and I’ll see you in the water.
