Alright folks, Rusty here. Let’s talk about what’s on offer for the next couple of weeks at Cobden Breakwater.

We’ve got a solid run of surf coming through, starting this Sunday, July 12th, and it’s looking like a classic winter stretch. The water temperature is sitting pretty normal for the time of year at 56°, so no weird surprises there.

The whole week is driven by a consistent, long-period groundswell. That dominant WSW swell direction is a perfect match for this spot. The energy is moderate to strong (666), but the period is a long 15 seconds, which means these waves will have real shape and power. The wind is a light cross-off from the east on Sunday morning, keeping things clean. It’s a great start, with clean 4 ft faces.

Monday morning gets a bit messy with a rain shower and a stronger cross-off wind, and the swell drops to 2 ft. But Monday afternoon? That’s a sneaky shift. The wind turns offshore from the NE, and the swell jumps to 6 ft, though the period drops to a short 7 seconds, so it’ll be a bit crumbly and less powerful. Still, clean waves.

Tuesday is a solid day. The swell is 5 ft with a 10-second period from the WNW, and the wind is light. It’s clean and very good. Tuesday afternoon, however, the swell gets bigger (7 ft) and the wind turns cross-shore, making it chopped up. That’s a pass.

The standout is Wednesday, July 15th. The morning is a bit iffy with onshore wind at 10 ft, but the afternoon is pure magic. The wind goes glassy, the swell holds at a solid 10 ft from the west with a 15-second period, and the energy is very strong (3563). This is proper, heavy groundswell. For experienced surfers, that’s your session. The wave energy is huge, and with the long period, it’s best suited to the breakwater’s structure here. Not one for learners.

Thursday and Friday are excellent for experienced surfers too, with 7 ft and 6 ft glassy or clean conditions. The energy stays high (1138-2055). The next Saturday, July 18th, also looks fantastic with a 7 ft swell from the WSW and a 16-second period, clean and strong.

The second week, from July 20th onward, is a lot quieter. The swell drops to 4 ft or less, but there are still some clean, glassy windows, like Monday afternoon and Tuesday morning. The energy is weak to moderate (434-582). It’s surfable, but nothing to write home about. By the end of the month, the swell fades into tiny, weak waves, with a few odd pulses of long-period energy that just don’t have the size.

Overall, the first week is where the action is. Wednesday afternoon is the one to circle on the calendar. Crowds are rare here, so you’ll likely have it to yourself.

Rusty.
