The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming down the pipe for Cobden Breakwater over the next couple of weeks. It’s a bit of a mixed bag, with some real standouts if you pick your days right. The water temp is sitting at 54.7°F, which is pretty much spot on for this time of year, so no surprises on that front.

The early part of the week is looking a bit rough, to be honest. Tuesday the 25th and Wednesday the 26th are mostly a write-off with cross-onshore winds and choppy conditions. The swell is there, but the quality is poor. We’ve got a bit of a lull until things start to come together.

The first real bright spot arrives on Thursday the 27th. We’re looking at a clean, offshore wind (ENE) in the morning and a 5.6ft swell from the WNW. The combined energy is moderate (697) and the long 9-second period from the WNW is solid. It’s a nice, clean setup for an intermediate session. The afternoon holds up with a clean 7.5ft from the NW and a cross-off breeze. This is the day to get out if you can.

Friday the 28th gets a bit hairy. The morning bumps up to a powerful 11.5ft from the NNW, but the onshore wind will make it a mess. The combined energy kicks up to 2858, but it’s too big and messy for a good paddle.

The tail end of the month has some serious potential for the experienced crew. On Monday the 31st, we get a massive 11.5ft swell from the W with a very long 16-second period. The combined energy is a whopping 5453. It’s too big for beginners, but with the near-glass winds (NE 3 mph) in the afternoon, it’s a heavy, clean, expert-only session. That Monday afternoon is the standout of this forecast period for strong surfers.

The first few days of September keep the long-period groundswell coming. Tuesday the 1st has 6.9ft from the W with a 16-second period and glassy conditions (ESE 0 mph), making for a clean and powerful session. Thursday the 3rd is another cracker, with a clean 9.8ft from the WNW and a 10-second period, with cross-offshore winds from the E. The combined energy is 2251, and the quality is excellent for those who know the break.

Looking further ahead to the second week, Sunday the 7th of September sees a massive spike in energy – we’re talking an 11.5ft swell from the W with a very long 18-second period and a combined energy of 6766. It’s glassy in the morning, but this one is for experts only. It’s promising but less certain at this range. Monday the 8th of September holds similar promise: an 8.2ft glassy morning with a 16-second period and combined energy of 3260. Another excellent, heavy session for the experienced.

Overall, if you’re looking for the best clean and powerful surf, lock in Thursday the 27th of August for a fun, intermediate session, and mark your calendar for Monday the 31st of August or Monday the 8th of September for the heavy, clean groundswell that the experienced crew will love. Crowds can be an issue here sometimes, so get in early.
