The Lowdown
Alright, Rusty here. Let’s talk about what’s on offer for the City Beach groyne stretch.
The next few days, honestly, are a mixed bag, but there are a few windows that are going to be well worth the paddle out. The water is sitting at 63°F right now, which is a solid 5°F colder than normal for this time of year, so you’ll be wanting a decent wetsuit – it’s bitingly cold out there.
We’ve got a bit of a lag before things get really good, but the first decent call is Tuesday morning, the 21st of July. The swell is a clean 5ft from the SW, with a period of 11 seconds, giving it a nice bit of shape. The wind is a light offshore from the ENE at just 5 km/h, so it’s going to be glassy and clean. That’s a real standout for the week. The combined energy is moderate at 624 – there’s enough push to get you into the wave.
Wednesday the 22nd keeps the run going. Morning and afternoon both look solid. We’re looking at 5ft and 4ft swell from the WSW, with the wind staying offshore (ESE and E). The period stretches to 13 seconds, which is a proper groundswell, so the waves will have some grunt and the sets will be well-spaced. The energy is moderate (715 and 877), but the quality is there. This is your best bet for a long session.
Thursday the 23rd is more of the same quality, with a moderate offshore breeze (ENE at 25 km/h in the morning, easing to 15 km/h in the afternoon). The swell drops a hair to 4ft, but it’s still a clean 14-second WSW groundswell. The energy is solid (672 and 515). It’s a good, fun surf.
By Friday the 24th, the swell backs off to 3ft, and while the afternoon has a clean offshore wind, the size is pretty marginal. The energy drops to 273. It’s a board-short wave, not a main event.
Saturday the 25th sees a bit more size come back to 4-4ft, but the wind is cross-off, not true offshore. It’s clean, but nothing to write home about. The energy is around 410-470.
Then we hit a rough patch. From Sunday the 26th through to the end of the month, the wind turns onshore and howls. The swell gets bigger – 7ft to 8ft – but with strong cross-on and onshore winds, it’s going to be choppy and lumpy. The energy is high (1268 to 1471), but it’s not surfable for a paddle. This looks more like a kite session, honestly.
The first week of August is a similar story. There’s a lot of energy on the 2nd (1446 to 1909) and 3rd (3105 to 3419), but the wind is a mess. Then on Tuesday the 4th of August, the swell absolutely pumps to 15ft from the W with a 15-second period. The energy is massive – 9027. But listen, that’s way too big for this break. The file says it’s predicted to be too big. That’s a big, dangerous, won’t-hold-up wave. It’s only for experts who know the place very well, and even then, it’s a gamble.
So, the clear standout is Tuesday morning (21st) and Wednesday (22nd). That’s your window. Clean, offshore, consistent groundswell. Get out there while it’s good.
Rusty.
