The Lowdown

Alright, Rusty here, let’s talk about what’s on offer. This is a rough stretch for the City Beach groyne. The next week and a bit is mostly a write-off, with a few tiny windows that might be worth a look if you’re desperate. The water is sitting at 62°F which is much colder than normal for this time of year, so you’ll want the thickest wetsuit you’ve got.

The pattern is ugly. Thursday the 6th is a no-go: you’ve got a 8ft WSW swell with a long 16-second period, but it’s messy with a cross-on NW wind at 9 mph, and the combined energy is a massive 3685 – it’s just not clean. Friday and Saturday are worse, with onshore winds cranking up to 28 mph and the swell jumping to 13ft on Saturday. The energy gets up to 6816 and 8953 but it’s all blown out.

Sunday morning the 9th is your first real chance – a 10ft WSW swell at 17 seconds, combined energy of 5149, but the wind is light and cross from the N at 6 mph. It’s marginal, but that light cross-shore might give you a few. The break is fairly consistent, but crowds are often here, so expect company.

Monday the 10th is a write-off again with a near gale from the WSW. Tuesday the 11th is a weird one – the swell is 15ft at 17 seconds, energy is a massive 11983, and the wind is clean cross-off from the SSE at 9 mph. That’s too big for this break though, unless you’re a very experienced surfer on a big board. Beginners, stay away.

Wednesday the 12th morning is the one standout. Glassy conditions with a WNW wind at 3 mph, and a 7ft WSW swell at 16 seconds. The energy is 2639 – moderate, but that glassy surface will make it clean. This is your best window for a paddle. It’s only for experienced surfers at that size, but it’s the best the week has to offer.

Thursday the 13th and Friday the 14th are both marginal with clean-ish conditions but smaller swell around 6ft to 7ft. The 14th Friday morning has a clean cross-off ENE breeze at 9 mph and a 7ft swell at 16 seconds – that’s a nice little session if you can get out. Then the weekend of the 15th and 16th is back to onshore junk.

The second week gets a bit more interesting. The 19th of August Wednesday has a 13ft WSW swell at 16 seconds, energy at 7857, and clean cross-off SE wind at 6 mph – but it’s too big for this spot again. The 21st Friday morning looks clean with a 10ft swell at 14 seconds and a light ENE breeze at 3 mph. That’s a long-range call, but it’s promising.

If you’re a kiter, this whole stretch, especially the big windy days, would be more interesting than paddling. For paddle surfers, the 12th morning is your best bet, and maybe the 14th morning if you want a smaller wave.

Rusty.
