The Lowdown
Alright, this is Rusty, checkin' in with a long-range look at City Beach groyne. Let's get into it.
We’ve got a bit of a slow start here. The first few days are pretty average with the wind onshore or cross-shore, making for messy, choppy conditions. But don't write it off just yet. The real action fires up later, and there are a couple of windows where this spot will really turn it on.
Monday the 24th is where we finally get a chance. The morning session is looking glassy, with that southwest swell coming in at 7 ft and a period of 14 seconds. It's a proper groundswell, packing some serious energy (1680). This one’s for the experienced crew though, as that size will be pushing it for beginners. The wind is dead calm, so you’re looking at clean, smooth lines off that groyne.
Now, Wednesday the 26th is a monster, but it's a tricky one. The swell jumps up to 12 ft in the morning, with a very long 19-second period and a massive 8984 combined energy. The wind is cross-shore, which will chop things up a bit. Then in the afternoon, the wind drops to glassy, and the swell hits 13 ft with even more energy (9098). This is huge, well over 8 ft, so this is strictly for experts only. It’s a beast of a swell, and that long period will make it a real handful, especially on a beach/groyne setup. It’s going to be a wild one if you’ve got the skill.
After that, things settle down but stay fun. The weekend of the 29th and 30th looks good. Saturday afternoon has a nice 4 ft swell with offshore wind and a clean face. Then Sunday the 30th morning is a standout. A clean 7 ft swell from the WSW with a 17-second period and a light cross-offshore breeze. The energy is strong (2855), and conditions will be excellent for experienced surfers.
Looking into the first week of September, there's another good window. Thursday the 3rd morning is looking glassy again with a clean 7 ft, 14-second swell. That's a prime session for anyone who can handle it.
The second week gets even bigger, but it’s more of a spectacle than a paddle. From the 5th of September onwards, the swell is predicted to be too big for this break. Saturday the 5th has a 13 ft swell, and Sunday the 6th is absolutely massive, with a 20 ft swell and a 17-second period packing a monstrous 19141 combined energy. That’s a king swell. The wind is forecast to be glassy on Sunday morning, but at that size, the groyne is going to be a washing machine. It'll be a sight to behold, but you’d want to be a very, very experienced charger or just leave the board in the car. Given the size and the beach setup, this is looking more like a kite surfer's playground than a paddle surfer's dream.
So, to wrap it up, the pick of the bunch is Monday morning the 24th of August for that first clean, glassy window. And then keep an eye on Sunday morning the 30th of August for another excellent, clean session. The big stuff mid-week and into September is for experts only, or just for watching.
Rusty.
