The Lowdown
Alright, Rusty here. Let’s have a look at what's in store.
First up, the main attraction: Cozies and Geeries. It’s a reef and point setup, and we’ve got a nice, long run of swell coming in from the west-southwest, which is exactly what this spot likes to see. The water temp is sitting about average for this time of year, nothing weird going on there.
Kicking things off on Sunday the 30th of August, it’s game on. The morning is the pick – crystal clear skies, a light 3 mph cross-offshore breeze from the east-northeast, and a clean 7 ft swell pushing in with a super long period of 18 seconds. That’s a proper groundswell, lots of energy (2678 combined energy), and that offshore wind will have the faces looking like glass. This is for experienced surfers only at that size; the power is real. The afternoon stays solid but the wind swings onshore and the quality drops – it gets a bit messy.
Monday the 31st is a write-off. Strong onshore winds and a jumbled up wave state – not worth paddling out.
Tuesday the 1st of September brings redemption. Another clean morning with that west-southwest swell holding at 7 ft, period still a fat 16 seconds, and a light cross-offshore breeze. Good, clean, powerful waves for the crew who know what they’re doing. The afternoon stays rideable but gets a little lumpy.
The next few days into Wednesday and Thursday see the quality fade. Winds turn onshore and the swell gets a bit choppy and weak. Friday the 4th of September is a big one – the swell jumps to 12 ft with a 15-16 second period. That’s big. Combined energy hits over 5800. It gets a "clean" read in the morning but that’s a whole lot of water moving for a reef/point. This is expert territory. The afternoon cleans up with a lighter cross-offshore, but still, 12 ft is no joke.
Saturday the 5th is still big, around 10 to 12 ft, but winds are light cross-onshore, so it’s a bit bumpy. The swell period drops, too, so it’s less organized.
Now, Sunday the 6th of September is a standout. Morning session: 8 ft, west-southwest swell, 14 seconds, and a clean offshore breeze from the southeast. That’s the kind of combo that gets me stoked. It’s clean, it’s got push, and everyone will be getting some gems. The afternoon stays clean but the wind picks up a notch. That morning window, though – that’s the one to circle.
Monday the 7th afternoon is another little highlight: 8 ft, clean, with a solid cross-offshore. The morning is a bit cross-onshore and choppy.
We get a couple of smaller, cleaner days on Tuesday the 8th (6 ft, glassy offshore) and Wednesday the 9th (5 ft, dead calm and glassy). Those are the beginner-friendly windows right there. Glassy conditions, smaller waves – perfect for getting the longboard out or teaching a mate.
The swell picks up again in the second week. Thursday the 10th and Friday the 11th are pretty average with onshore winds. Saturday the 12th gets big again – 12 ft from the west at 14 seconds – but winds are cross-onshore, so it’ll be bumpy and tough.
Then we hit the real late period. Sunday the 13th of September afternoon is a prime candidate: 12 ft, solid 17-second period from the west-southwest. Combined energy is huge at 6449. The wind is light and cross-shore, so it’s clean and rippable. This is powerful, world-class level stuff.
Monday the 14th of September ramps it up even more. 12 ft, strong west-northwest swell, period 16 seconds, and the combined energy hits 10040. That’s a lot of ocean moving. The wind is light onshore, so it’s a bit lumpy on top, but for the experienced crew, the raw power is there. That is a massive swath of energy. This one is for experts and big-wave chargers only. It’s promising this far out, but you’ll want to keep an eye on it as it gets closer.
Bottom line: The best windows are the mornings of Sunday the 30th, Tuesday the 1st, and Sunday the 6th of September. And for the brave, the afternoon of Sunday the 13th and Monday the 14th are looking like proper heavy water sessions.
Keep it shralpy,
Rusty
