The Lowdown
Alright, Rusty here, let's break down the next couple of weeks for Westport-The Groins.
So, looking at the whole picture, we've got some challenges ahead. The water is 60°, which is pretty normal for this time of year, so you know what to expect. For the first week, we’re dealing with a lot of cross-onshore wind that's just going to mess up the surface. The swell is small, mostly 3ft to 4ft from the WNW, but the energy is weak to moderate (306) and the period is short, so those waves are going to be weak and disorganized. You might find a clean wave Monday morning with a 3ft swell and a light cross-offshore wind, but it's nothing special. After that, it's mostly "leave your board at home" kind of days.
Now, if you can wait, the real highlight is the morning of Tuesday, September 22nd. This is the one. We’ve got a solid 5ft swell rolling in from the WNW, and the energy is going to be strong (915) with an 11-second period, so there’s some real power behind it. The best part? The wind is forecast to be glassy. Dead flat. This is your best chance for clean, punchy waves by a long shot. Just a heads up, 5ft is pushing into intermediate and expert territory, so it's not for the faint of heart. Being a beach and jetty set-up, the longer period might make the waves a bit dumpy, but with glassy conditions, you'll still have a blast. Crowds can show up here "sometimes," so expect a few others who had the same idea.
That morning window is your golden ticket, because the wind switches onshore by the afternoon and it’s back to choppy mess. The rest of the month is pretty quiet. There are a few mornings around the 28th and 29th where the wind goes light offshore or glassy, but the swell is down to 2ft. The energy is moderate (292-337) and the period is long (15-16 seconds), so you’ll get some clean little lines perfect for a longboard. Nothing to write home about.
So, in short: battle through the windy junk for the first week, and be on the water for that Tuesday the 22nd morning session. That’s the one that’ll make it all worth it.
Rusty.
