The Lowdown
Alright, Rusty here. Let’s have a look at what’s cooking for Westport-The Groins.
First thing you gotta know – the water is a touch warmer than normal for this time of year, sitting at 62°, which is a nice little bonus.
Alright, let’s get into it. The first proper session to really get excited about is Saturday, September 12th. We’ve got a glassy morning with a clean, 3ft southwest groundswell rolling in at a long 15 seconds. The wind is light, straight out of the south-southwest, making for some real clean lines at the Groins. The combined swell energy is moderate at 492, so there’s some push behind it. Saturday afternoon stays clean with a cross-off breeze and the swell holding at 3ft.
Sunday the 13th is a write-off. The wind gets up, and the swell drops off – not worth paddling out.
Monday the 14th is ordinary. There’s some surf in the morning, a 3ft swell, but the period has dropped right off to a short-burst 8 seconds. The wind is okay, but the waves just won't have any shape.
The next real standout comes almost a week later, on Monday, September 21st. The morning is absolutely glassy again, with a nice 3ft southwest groundswell at a very long 18 seconds. The combined energy is strong too, at 407. This is a proper groundswell. The only thing to keep in mind with such a long period at a beach/jetty setup is it can break a bit straight, but with that light wind, it should be worth a look for a few. The afternoon gets a bit mixed with some cross-shore chop.
Looking into the second week, the only bright spot is Thursday morning, September 24th. The swell bumps up a touch to 4ft from the west-northwest, still a decent 10-second period, and it’s glassy. Combined swell energy is at 408. That’s a promising window, but it’s a long way out, so don’t set your watch by it yet.
After that, the rest of the outlook into the end of September is pretty grim with wind and choppy conditions. The Groins is a fairly consistent spot, so keep an eye on the forecasts; it rarely stays flat for long.
This is Rusty, signing off.
