The Lowdown
Alright folks, Rusty here with a look at what’s on the menu for the next couple of weeks at Westport-The Groins (Westport-The Groins). Right off the bat, I gotta be real with you – it’s a slow start, with a whole lot of nothing happening for the first several days. The water temp is sitting right around 59°, which is pretty much bang on average for this time of year, so no surprises there.
Through the back half of August and into the very start of September, we’re looking at a pretty grim stretch. The swell energy is weak, mostly in the 100-200 range, and the winds are almost always cross-onshore, making for choppy, messy conditions. You’ll see a few morning windows with a gentle offshore breeze, like Friday the 21st with a 3ft WNW swell, but the overall energy is weak (272) and the wave quality is just ordinary. Things don’t really improve through the weekend and into the following week. The swell stays small, under 2ft, and the wind stays on it or cross-shore, keeping the surf pretty flat and uninviting. There’s a long gap of really poor conditions here.
Now, if you’re patient, there’s a glimmer of hope waiting for us. The real standout, the best on offer, comes on Thursday, September 3rd. The morning session is looking like a solid pick. We’ve got a clean 6ft WNW groundswell rolling in, with a moderate energy reading of 509 – that’s decent punch. The wind is glassy, swinging around from the north at just 3 mph, which means the faces will be smooth. That size is a bit much for beginners, but for the rest of you, it’s the best window in the entire forecast. The morning is clean, but by the afternoon the wind will swing cross-onshore and chop it up, so get out there early.
The next day, Friday the 4th, sees a similar 5ft WNW swell, but the wind is already cross-onshore, so it won’t have the same quality. And after that, we’re back to small, ordinary conditions with a clean but weak SW swell on the 5th and 6th.
So, to sum it up: a long, flat start, one absolute gem of a session on the morning of Thursday the 3rd of September, and then a return to small stuff. Set your alarm for that Thursday morning and you’ll be rewarded.
Rusty.
