The Lowdown
Alright folks, Rusty here. We’ve got a 16-day window for Westport-The Groins, and it’s a bit of a mixed bag. No massive standouts, but there are a couple of windows where it’ll be well worth wetting a line.
The overall pattern is one of small, inconsistent swell with a lot of choppy, onshore wind. The first few days are pretty grim, with a lot of poor surf conditions and cross-on wind. Saturday September 5th is a no-go, with wind ripples and marginal surf. The gap in quality surf stretches through until the end of the first week.
Your first real chance to get out is Sunday morning, September 6th. It’s not huge, but it’s clean. We’ve got a 3ft SW swell with a long 17-second period, and glassy conditions with light west wind. The combined energy is moderate (409). This is a classic small groundswell for the jetty, and with the glass, it’ll be the pick of the early days. It’s a sheltered spot, so that 3ft will feel a bit more user-friendly. The water temp is about average for this time of year.
The next real highlight is Friday morning, September 11th. Another dose of glassy conditions, with a 2ft SW swell and a long 17-second period. The combined energy is a bit stronger at 593. This is another clean, small morning session. The jetty will be the spot to pick off the lefts.
Looking further ahead, the second week brings a pulse of energy. Wednesday morning, September 16th sees a 4ft SSW swell, but a short 7-second period and onshore wind make it messy. The wind stays onshore, so we have to wait for the real change.
The standout in the whole forecast is Friday morning, September 18th. Swell bumps up to 6ft from the W with a 10-second period, and the wind is completely glassy. The combined energy is strong (830). This is the biggest, cleanest swell of the run. It’s a solid 6ft, so it’s getting into expert territory, but on a glassy morning at the jetty, you’ll get some proper, powerful waves. The only downside is that with crowds possible, this will be a popular one.
Saturday morning, September 19th is also a good call. A 5ft WNW swell, slightly shorter at 8 seconds, but with clean conditions and a light offshore breeze from the SE. The combined energy is moderate (610). The offshore wind will hold the waves up nicely.
The last mention is Sunday morning, September 20th. The swell drops back to 2ft from the SW, but with a very long 18-second period and a gentle offshore wind from the south. The combined energy is moderate (516). It’s a clean, small groundswell to finish the run.
So, if you’re picking one, make it Friday morning, September 18th for the biggest, cleanest power. The Sunday morning, September 6th and Friday morning, September 11th are your go-to for small, clean, glassy waves.
Rusty.
