The Lowdown
Alright folks, Rusty here. Let's get into it.
We're looking at a mixed bag over the next couple of weeks. The swell is coming in from the west-southwest, which is just what City Beach groyne likes, but the wind is going to play games with us. There's some real quality to be had if you pick your moments, especially early on, but there are also a few days where you’ll want to leave the board in the car.
The pick of the entire run, without a doubt, is Wednesday morning the 12th. It’s not the biggest swell, coming in at a clean 7ft from the WSW, but that period of 14 seconds is packing a punch with moderate wave energy (1670). The real story here is the glassy conditions. The wind is light out of the north, and the water is flat – it'll be a dream out there. This is perfect for anyone who can handle a 6-foot wave; you could even stretch a log here. For beginners, this 7ft might be a bit much, so choose your lineup wisely.
Wednesday afternoon the 12th is a step down with a cross-shore breeze, and by Thursday morning the 13th we get a cleaner look with a cross-offshore wind from the NE and 6ft of 16-second swell (1692). It’s solid, but the real gem is Friday afternoon the 14th. We're back to glassy conditions, with a 3 mph southeasterly making things perfect. The swell is 6ft from the WSW with a 16-second period (1743). That’s a long wait between sets, but the shape will be gorgeous on that groyne.
We have a bit of a lull over the 15th and 16th, but Saturday afternoon the 15th is worth a mention. The wind goes glassy from the west again, with a 6ft, 14-second WSW swell (1057). It’s a bit smaller, but it’ll be clean.
Now, look out for the 19th. Wednesday morning the 19th is a beast – 13ft from the W with a short 11-second period. That’s a huge, chunky swell (3601). The wind is cross-offshore, so it’ll be clean, but that’s expert territory only. There’s a warning in the data saying it’s too big for this break, so if you're not at the top of your game, give it a miss. For everyone else, the waves will be thick and powerful on that bank.
The rest of the week is mostly wind-affected or messy. There’s a window on the 23rd and 24th with dropping swell, but the wind isn't cooperative. The final highlight is Wednesday morning the 26th. It’s a while away, so treat this as promising. A 5ft, 16-second WSW swell (2037) with a clean cross-offshore SSE breeze. It'll be good for a paddle.
Overall, it's a classic early-season pattern. The best windows are tight and you have to be on them. Wednesday the 12th and Friday the 14th are your standout calls. See you in the water.
Rusty.

The above surf forecast table for City Beach groyne provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at City Beach groyne can be found by selecting the local surf guide option on the grey menu.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for City Beach groyne may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
