The Lowdown
Hey folks, Rusty here. Let’s take a look at what’s coming up for City Beach groyne over the next couple of weeks.
Right off the bat, the water temperature is sitting at 62°, which is a couple of degrees colder than normal for this time of year – so you’ll want a thicker wetsuit if you’re heading out. The early part of the forecast is a bit of a mixed bag, but there are some real gems to get excited about if you’re patient.
The first decent chance comes on Tuesday morning, September 1st. We’ve got a clean 5 ft groundswell from the WSW with a great long period of 16 seconds, combined energy is strong at 1338. The wind is light and cross-off from the SSE, so the surf should be clean and well-shaped. This is one for the experienced surfers, as the swell is solid and the period means longer sets. It’s the standout of the early week.
The rest of that week is messy. Wednesday and Thursday see a mix of onshore winds and some rain, with the swell picking up to 7-8 ft, but the wind is mostly cross-on or onshore, making things choppy and unappealing. The combined energy climbs up to 2152 on Thursday afternoon, but with a fresh breeze from the west, it’s messy. Nothing to get excited about there.
Friday September 4th morning is a write-off – 10 ft swell but with a moderate cross-onshore SW wind, making it choppy and rough. The afternoon looks a bit better with a light cross-shore breeze and the same 10 ft swell, but it’s still marginal. Saturday and Sunday (September 5th and 6th) are a no-go – strong winds, heavy rain, and blown-out conditions. The swell is actually huge (15 ft on Saturday afternoon), but with a near gale cross-onshore, it’s only for the very brave or the kite surfers.
Now, here’s the real gold. Monday morning, September 7th, is glassy calm with a 8 ft WSW groundswell pumping in at a 16-second period. The combined energy is huge at 3609. This is clean, powerful, and for experienced surfers only. The waves will be well-formed, and the glassy conditions make it a top pick.
Tuesday morning, September 8th, is another beauty – glassy conditions from the east, a 8 ft WSW swell with a long 16-second period, and combined energy of 2859. This is clean, powerful, and again for the experienced crew. If you can only get out one day, this is it.
The second week starts to fade a bit. Wednesday September 9th has a cleaner cross-off wind but smaller swell – 6 ft dropping to 5 ft, still decent. The rest of the week sees a lot of moderate to fresh winds and lumpy conditions, with the swell hanging around 7-8 ft but often choppy or bumpy.
The next standout pops up on Saturday morning, September 12th – a clean 8 ft WSW swell with a moderate offshore wind from the east, combined energy of 2084. It’s got that offshore groomed look, and it’s another one for the experienced surfer. The afternoon is also nice with a light cross-off.
Sunday morning, September 13th, is glassy and 5 ft – a good option for a relaxing session, but nothing huge. The last real highlight is Tuesday morning, September 15th, with a gentle offshore from the east and a clean 8 ft WSW swell, combined energy 2441. That’s a solid way to wrap up the run.
Overall, the best of the bunch is Monday September 7th and Tuesday September 8th mornings – glassy, powerful, clean groundswell. If you’re an experienced surfer, get on it. The rest of the period is a mix of messy or marginal conditions, with a few smaller windows of clean surf.
Rusty out.
