The Lowdown
Alright folks, Rusty here. Let's have a look at what Westport and The Groins have got cookin' for us over the next couple of weeks.
Right off the bat, I gotta be honest with you – it's a bit of a slow start. The first few days are lookin' pretty grim. We've got a small, long-period SW groundswell rollin' in, but the wind is just a mess, choppin' everything up. The water is a touch warmer than normal for this time of year, sittin' around 63°F.
We're lookin' at a real quiet spell. From Sunday the 30th of August right through to Wednesday the 3rd of September, it's basically a write-off. The swell is there, but it's small and messy, and the wind is all over the shop. You'll be fightin' a losing battle.
Things start to look a little more promising on Thursday the 4th of September. The swell is still modest at 5ft from the W, but we get a clean, offshore wind from the S in the morning. The energy is moderate (550), and it's a groundswell with a period around 9 seconds, so it'll be shapin' up alright. It's a good, clean beginner-friendly wave.
Then we get a proper tease on Friday the 11th of September. The morning is glassy, with a clean 4ft WNW swell. The energy is moderate (500). It's a fleeting moment of perfection, but it won't last.
The real standout, the one you circle on the calendar, is the weekend of the 13th and 14th of September. Sunday the 13th of September is where it's at. We've got a solid 8ft WNW groundswell, with a long period of 10 seconds, pushin' through with strong energy (1350). The wind is offshore, light, and clean. This is a proper wave. It's brewin' up a bit of size, so it's more of an intermediate to expert wave, but the conditions will be top shelf. The Groins will be workin' a treat.
Look, the crowds are listed as "sometimes" at this spot, so you might have a few friends out, but for a session like that, it'll be worth every bit of company.
To sum it up: the first week is a total dud. The best of the bunch is the morning of the 4th of September for a clean, small wave, and the absolute standout is Sunday the 13th of September for a proper, clean, meaty swell. Don't sleep on that one.
Rusty.
