The Lowdown
Righto, let’s have a look at the coming stretch. For the next sixteen days, Cozies and Geeries is our only spot on the radar, and it’s got a bit of a mixed bag – some real gems buried in there, but also some rough patches to sit through. This is a reef and point setup, fairly consistent, so when the swell and wind line up, it’s worth the paddle.
We kick off on Wednesday the 19th. The morning is a write-off – cross-on wind and choppy 8ft swell, with the combined energy sitting at 2868 (moderate to strong). Not great. But then the arvo turns it around: 10ft of WSW groundswell, period a solid 15 seconds, and a clean cross-off breeze. The energy jumps to a meaty 4208 (moderate to strong). This is for experienced surfers only – over 8ft and powerful. That’s a standout session for the crew who know what they’re doing.
Now, Thursday the 20th morning is the absolute pick of the first week. Glassy conditions, 8ft WSW swell with a long 16-second period, and 3594 (moderate to strong) energy. It’s clean as a whistle, offshore wind from the north. This is a special morning. The afternoon holds clean cross-off winds too, so you can stretch the session out. Crowds are possible here, so get in early. Crowds are possible here.
Friday the 21st stays clean with morning cross-off winds and 8ft of WSW swell, energy at 2302 (moderate). It’s solid but not quite as punchy. The weekend sees the swell drop but stays glassy on Saturday morning – 6ft with a 16-second period, 1875 (moderate) energy, and glassy wind. That’s a lovely clean session for the intermediate crew, though it’s still got some weight.
There’s a dip in quality from Sunday the 23rd through Monday the 24th: the swell hangs around 5ft to 6ft but the wind turns cross-on and the energy drops. Tuesday the 25th is a write-off with onshore wind and lumpy, poor surf – energy down to 475 (weak). You’d be better off doing something else.
Now, here’s the big one: Wednesday the 26th. Morning delivers a serious 10ft WSW groundswell with a very long 17-second period, and the energy rockets up to 5378 (strong). That is exceptional for experts only – it’s going to be big, powerful, and clean with cross-off light breeze. This is the standout of the whole forecast, but it’s over a week away, so keep an eye on it. The afternoon stays excellent for experienced surfers.
We roll into Thursday the 27th with clean 7ft swell, Friday the 28th drops to smaller 4ft, and then Saturday the 29th has a weird one – 3ft but with an 18-second period, energy at 873 (weak). That’s a long-period groundswell but tiny; it might wrap nicely around the point but won’t have much push.
The final week sees a little pulse again around Monday the 31st: 6ft of WSW, 15-second period, clean cross-off in the arvo, energy at 1687 (moderate). Then into early September, we get a build again on Wednesday the 2nd with 8ft, 17-second period, and 3053 (moderate to strong) energy – but the wind is light cross-on, so it’s not quite perfect.
Overall, the absolute standout is that Thursday the 20th morning glassy session, and the other big one is Wednesday the 26th for the heavy crew. There’s plenty of clean surf in between but be patient through the flat blips. That’s it from me. Rusty.
