The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming up for Cobden Beach - The Channel.

We’re in for a wild ride, but you’ve got to pick your moments. The start of the period is absolutely pumping with energy, but it’s a real beast—way too much for most of us. The best window for the average surfer is actually further out, around the start of August.

The first real action hits this Saturday morning, July 25th. The Channel is seeing a massive 10-foot swell from the west, with a very long period of 16 seconds. The combined energy is a staggering 4309 (strong to very strong wave energy). The wind is glassy from the southeast, which is a dream. But honestly, at this size, it’s a monster. This is only for the absolute top-tier experts. The water temperature is about average for the time of year.

Saturday afternoon, July 25th, is even bigger – 13 feet from the west, 15-second period, and energy up to 6162. Still glassy, but same warning: it’s a beast. The morning of July 26th drops to 7 feet from the west with a 14-second period, energy at 1719, and a clean cross-offshore breeze. That’s a bit more manageable for strong intermediate surfers, but still a solid, powerful groundswell.

The real standout, the one that gets my heart racing, is Monday, August 3rd. The morning brings a 7-foot swell from the west with a 20-second period – that’s a very long period groundswell. The combined energy is 3049. The wind is a clean cross-offshore from the SSE. For a point break or reef setup like this, that period is magic. It’s going to be powerful, lined up, and with that light offshore, it’s gonna be an absolute dream. This is for experienced surfers only, but it’s the pick of the entire forecast. The afternoon of the 3rd drops to 5 feet, still excellent.

The morning of Tuesday, August 4th, is another good one. A 6-foot swell from the west-southwest, 15-second period, and 1708 energy, with clean cross-offshore winds. This is a solid, high-quality backup day.

The first week also has some okay windows. Monday morning, July 27th, has 6 feet from the west with a 12-second period and offshore winds, but the energy is lower at 900. The Tuesday morning, July 28th, is smaller at 4 feet with 284 energy and clean winds. These are just okay, not the standouts.

There is a big gap of poor conditions from the end of July into the first few days of August. The 30th and 31st of July are blown out or too big, with onshore winds and messy conditions. The morning of Saturday, August 1st, is still too big for comfort at 7 feet, and the wind is only glassy in the morning, so it’s still a big, powerful swell.

After the August 4th window, the swell starts to fade. We get small, clean waves on the 5th and 6th, with waist-to-chest high sets, but nothing to get too excited about. The 7th and 8th are tiny, mostly knee-to-waist high, and the 9th brings a small bump of 3 feet from the north, but it’s nothing special.

So, bottom line: the pick of the month is Monday, August 3rd. Get ready for that. The early part of the weekend is a big-wave spectacle for experts only. The rest is a waiting game.

Rusty.
