The Lowdown
Alright, let’s talk waves. We’ve got a slow couple of weeks, but there’s definitely some gold in them there hills if you’re willing to wait it out.
Right off the bat, Thursday the 10th has some knee-to-waist high lines early with a light offshore breeze, but it gets messy by the arvo. Then Friday and Saturday mornings are glassy but way too small to get worked up about. You’ll be bored.
Sunday the 13th brings a bit more push, chest-high stuff, but the wind swings onshore and wrecks it. Now, Monday the 14th is your first real session. The morning is dead flat calm with a solid 4ft of clean NW groundswell. It’s going to be smooth and rippable. That’s a proper window.
After that, it’s a bit of a lull. Tuesday has a clean but small wave, and then Wednesday and Thursday are total write-offs with fresh winds and rain. Not worth the hassle.
Keep your eyes on the prize: Monday, September 21st. This is the big one. We’re talking a solid 8ft of NW swell with a long 14-second period. The energy in the water is massive. The morning is glassy, which is exactly what you want on this reef. This is serious, expert-only territory. It’s going to be a proper show. The next morning, Tuesday the 22nd, still has good size and clean conditions, a solid follow-up.
The swell fades out pretty hard after that, dropping to nothing by the end of the week. That big Monday is the standout, no question. The Monday before is a good warm-up if you want something a bit more forgiving.
Rusty signing off.
