The Lowdown

G’day, Rusty here. Let’s run through what’s coming up for the next stretch.

The surf fires up on Tuesday, 28 July, with a clean little wave. Nothing huge, but it’s a solid start. Cobden Beach - The Channel is the only spot in play. The morning brings a 4ft W swell, 11 seconds, and a light cross-offshore breeze from the ESE. The water’s at 54°, which is about average for the time of year. The combined energy is moderate (328). The afternoon glass off is a beauty: clear skies, 4ft, glassy as a mirror. It’s small, but it’s clean.

Wednesday, 29 July, is the first real highlight. The morning has a 3ft WSW swell, but the period jumps to 14 seconds, and the combined energy is strong (608). With a light cross-off breeze, it’s clean and lined up. The afternoon is the winner: 5ft WSW at 14 seconds, glassy, and energy at 745. It’s a classic winter’s day, small but punchy, and the best on offer this week.

Thursday, 30 July, starts to lose it. Morning is cross-shore and choppy, with a 4ft W swell, 13 seconds, but the wind is a cross-breeze and the combined energy is moderate (661). The afternoon turns ugly: 8ft NW, short period (8 seconds), and a strong 19 mph cross-onshore wind. That’s lumpy, messy, and the energy is over 1200. For paddle surfing, it’s a write-off. If you’ve got a kite, this setup might be more fun.

Friday, 31 July, is a full-on blowout. 12ft and 18ft swells, high winds, and onshore conditions. The energy is massive (2322 and 12190). This is expert-only at best, and honestly, it’s more of a spectacle than a session. A beach break with this much juice and wind is going to be a washing machine. Not for beginners.

Saturday, 1 August, starts with an 8ft W swell, 12 seconds, and clean cross-offshore wind. The energy is 2041. The comment says it’s too big for this break, so respect that. The afternoon is a gem: 6ft W, 10 seconds, glassy, and energy at 712. It’s clean, fun, and the best of the weekend.

Sunday, 2 August, is small but sweet. Morning has 4ft W, 8 seconds, and clean conditions. The afternoon is tiny with a 1ft WSW swell, but the period is a massive 22 seconds – that’s very long period groundswell. Combined energy is 346. It’ll be glassy and clean, but you’ll be waiting for sets. Good for a longboard or a quiet paddle.

Monday, 3 August, brings a 4ft WSW swell, 18 seconds, and moderate energy (943). The morning is clean with a cross-off breeze. The afternoon gets a bit wind-affected with cross-on wind, but it’s still rideable. The long period means this is better at a point or reef than a beach break – it’ll break too straight for the beach.

Tuesday, 4 August, is another standout. The morning has 4ft WSW, 15 seconds, and clean offshore wind. The afternoon is the best of the whole run: 6ft WSW, 14 seconds, glassy, and energy at 1557. This is excellent for experienced surfers – proper power, clean lines, and a nice size.

Wednesday, 5 August, morning is small and clean at 3ft, 13 seconds. The afternoon jumps to 10ft WSW, 8 seconds, and clean wind, but the comment says it’s too big for the break.

Thursday, 6 August, rounds out with clean 4ft and 4ft W swells, good periods, and glassy conditions.

The gap from Friday, 31 July, to Saturday, 1 August afternoon, is a full day of messy, oversized surf. After that, there’s a solid run of clean but smaller waves. The week of 4 August onwards has a few more promising days, especially Tuesday afternoon and the very long period glassy afternoon on 11 August.

The standout days are Wednesday, 29 July afternoon, and Tuesday, 4 August afternoon. Both have clean, glassy conditions, solid period, and moderate energy. The swell direction (WSW) matches the optimum. If you can only pick one, 4 August afternoon is the best: 6ft, 14 seconds, glassy, and energy at 1557. It’s a surfer’s day.

Crowds are rare at Cobden Beach - The Channel, so you’ll have plenty of room.

Rusty.
