The Lowdown
G’day, Rusty here, and I’ve had a proper look at what’s on the cards for Cozies and Geeries over the next 16 days. It’s a mixed bag at best for a while, with a fair bit of junk to paddle through before the real magic shows up late in the game. First off, the water’s sitting at 63°, which is a touch below the long-term average for this time of year—nothing wild, just a little cooler than usual.
The first standout is the morning of Monday the 14th. That’s when it all clicks. You’ve got a solid 8ft swell pushing in from the WSW, with a clean 14-second period, and the wind is a light cross-off from the ENE at just 3 mph. The water will be glassy, the lines will be clean, and the combined wave energy is strong at 2027. This is full-on for experienced surfers only at that size. A true gem.
Then, hold onto your board, because Tuesday the 15th morning is another cracker. A 7ft WSW swell with a 15-second period and offshore wind from the SE at 6 mph. The energy is still pumping at 1994, and conditions will be pristine. Again, this one’s for the crew who know what they’re doing—big, powerful groundswell.
Now, look out for the very end of the run. On Monday the 21st of September, there’s a monster swell on the way—10ft from the WSW, with a 17-second period and an energy reading of 4494. The wind is light cross-onshore in the morning, but the afternoon cleans right up with a cross-off breeze from the SW at 19 mph and energy hitting 5534. That’s big, that’s raw, and it’s for experts only. The following few days hold similar size—12ft on Tuesday the 22nd morning—but the wind gets stronger, so it’s a bit of a lottery.
If we’re picking the absolute best on offer, I’m calling Monday the 14th morning and Tuesday the 15th morning as the standouts. Clean, powerful, long-period groundswell and light offshores. Don’t sleep on the 21st and 22nd either—massive energy, but it’s a long way out, so keep an eye on it. Crowds are possible at Cozies and Geeries, so get in early.
Rusty.
