The Lowdown
G’day, Rusty here. Look, I’ve been through this forecast for the next couple of weeks, and it’s a tough one. The swell is gonna be pumping, but most of the time it’s just too damn big for this spot. Cobden Beach – The Channel is a beginner-friendly break, but when the swell hits over 8 feet, it’s strictly for experts, and even then, it’s a beast. The first real opportunity doesn’t come until the morning of Saturday, July 18th.
The water is sitting at 55°F with a normal temperature for this time of year, so nothing unusual, just your standard winter chill.
The standout window is the morning of Saturday, July 18th. We’ve got a solid 6ft swell from the WSW, with a long 15-second period – that’s proper groundswell energy. The wind is glassy, dead calm, so the surface will be like a mirror. The combined energy is high (1421), so there’s plenty of push. This is the best on offer: clean, powerful, and a bit of a challenge. Because the swell is 6ft, it’s right on the edge for beginners, so it’s more for the experienced crew.
Sunday morning, July 19th, is also worth a look. The swell is a touch bigger at 7ft from the W, still with a long 16-second period, and the wind is light and offshore from the E, keeping it clean. The energy is even higher (1962). But again, it’s getting into the bigger range, so be ready.
After that, the swell drops right off. From Monday, July 20th, through to Thursday, July 23rd, it’s small – around 3ft to 5ft – with weaker energy in the 200-400 range. The wind is often glassy or clean, so it’ll be pretty, but not much to get excited about. Friday, July 24th, stays small and clean.
Then, on Saturday, July 25th, it gets ugly. Rain showers and a strong 12 mph cross-onshore wind from the N make for a messy, choppy day. That’s a write-off.
Things turn back on Sunday, July 26th, but it’s back to the big stuff again. The morning has a 8ft swell from the WSW with a 15-second period and clean offshore winds from the S, and the energy is massive (3043). The afternoon is similar, with glassy conditions. This is another expert-only window. It’s gonna be powerful and borderline intimidating.
Monday, July 27th, morning is a good option for experienced surfers – 5ft from the W, 16-second period, clean offshore winds, and a solid energy level (1265). Then it drops off again.
The pattern repeats into the end of the month. Tuesday, July 28th, and Wednesday, July 29th, see more big swell (7ft to 10ft) and strong energy, often with cross-onshore winds, making it a bit of a scrap. The morning of the 29th is a standout for the big-wave crew – 10ft from the WSW, offshore wind, and a massive 4240 energy – but it’s a serious session.
In short, the best bets are the mornings of July 18th and 19th and the morning of July 27th for the experienced crew. The big stuff on the 26th, 28th, and 29th is for experts only. The rest is either too small, too big, or too windy. Stick to the glassy windows and pick your days.
Rusty.
