City Beach groyne Surf Forecast and Surf Report

Alright, grab a coffee, sit down, and let’s talk about the next couple of weeks at your local. We’ve got a bit of a mixed bag ahead, so let’s dig in.

The opening window is actually pretty special if you’re experienced. Starting on Monday, September 7th, the morning at City Beach groyne is looking clean with a light easterly breeze and a solid 8ft WSW groundswell. That’s a long 16-second period, so there’s plenty of energy in the water (combined energy of 2853), but those sets will be spaced out. For a beach/groyne setup like this, the longer period might make it break a little straight, but it should still offer good shape. Water temps are a bit colder than normal at 63°, about 2° below average, so you might want a spring suit. This is the standout of the whole run, but only for experienced surfers—that size and power isn’t for beginners. Crowds are often an issue here, so you’ll probably have company.

Monday afternoon stays clean but the breeze picks up, and the score drops. Better off hitting it early.

Tuesday morning, September 8th, is similar—8ft, 17-second swell, but a fresher breeze makes it less appealing. The conditions are still clean, but the wind is stronger. Not a write-off, just not as good as Monday morning.

Wednesday, September 9th, things start to shift. The swell drops to 6ft in the morning with a 15-second period, but the wind turns offshore from the ENE at 19 mph. That’s a nice offshore, so the waves will be clean. Combined energy drops to 1735, so you’ve got less grunt, but it should be more user-friendly for a wider range of surfers. Still not ideal for beginners given the size, but manageable.

Thursday, September 10th, the swell backs off to 4-5ft and the period drops slightly. It is clean, but it’s small. If you’re on a log or a fish, there might be something, but it’s not going to light the world on fire.

Then we hit a rough patch. From Friday, September 11th, through the weekend and into early the following week, conditions get nasty. Onshore winds, lumpy seas, and growing swell. Saturday sees 8ft building to 10ft onshore junk—that’s a mess, and combined energy spikes to over 4662. Not worth paddling out for a surf; more of a kite day if you’re into that.

Sunday, September 13th, stays onshore with 5ft to 8ft—still poor.

By Monday, September 14th, we get a reprieve. The morning offers clean 7ft WSW groundswell (14 seconds) with light offshore winds again. Combined energy of 1751. Another good window for experienced surfers, and it’s clean. Crowds likely.

Tuesday, September 15th, is glassy. Absolutely glassy. Winds from the WNW at only 3 mph. That’s magic. Swell is 6ft from the WSW with a 14-second period. Combined energy of 1308. This is your second standout—glassy conditions and a decent swell. Not huge, but clean as a whistle. All levels could have fun here, but the 6ft will still push beginners a little.

After that, the second week gets messy. From Wednesday, September 16th, onshore winds return, and we see 10-12ft onshore slop by Thursday and Friday. That’s too big and too ugly for City Beach groyne. The combined energy hits over 5900 on Friday morning, but it’s cross-onshore and choppy. Don’t bother.

There’s a glimmer on Sunday, September 20th, with a 8ft WSW swell and light winds, but it’s cross-shore, not offshore. Combined energy is 2734—decent, but it’s not the gem of the window.

The very last day, Monday, September 21st, has another glassy morning with a very long 12ft swell from the WSW at 19 seconds. That’s a huge groundswell. Combined energy of 8356 tells you there’s a ton of power. Wind is glassy offshore, but that size is for experts only. It could be epic if you’ve got the skill, but for most, it’s a watch-and-wonder day.

So the two best calls are Monday morning, September 7th, and Tuesday morning, September 15th. The first has more size and power for experienced surfers; the second is glassy and a bit smaller, making it the more accessible standout of the run.
