The Lowdown
G’day, Rusty here. Let’s be straight with each other: it’s a pretty lean stretch ahead for surf around Westport-The Groins. We’re looking at a long, quiet run where you’ll be waiting more than you’ll be riding.
The action really doesn’t kick off until Friday morning, 14 August, when the first surfable waves show up. That’s a gap of a couple of days from the start of the period with nothing worth paddling for.
Friday 14th looks clean in the morning – light offshore winds from the SW and a small 2ft groundswell with a nice long 16-second period. The combined wave energy is moderate at (207), but honestly, it’s barely ankle to calf high. It’s surfable but very ordinary. Afternoon goes messy.
Saturday 15th is similar: clean again in the a.m. with light cross-offshore breeze, 2ft swell from the SW and a very long 18-second period – that’s proper groundswell, but tiny. Energy a touch higher (331), but still very small.
The standout window, if you can call it one, looks to be the morning of Thursday 20 August. We’ve got a bit more size – 4ft from the WNW, period around 11 seconds, and the combined energy jumps to a moderate-to-strong (550). What’s more, it’s glassy with a light offshore N wind. The swell direction lines up with the optimum for this sheltered break (WSW). This is the best on offer across the whole outlook, but it’s still described as marginal due to questionable tide conditions, so don’t expect perfection.
Friday 21 August morning also offers a tiny clean window – light offshore from the S, 3ft WNW swell (272 energy) – surfable but nothing to write home about. Saturday 22 August morning stays clean with 4ft WNW swell and cross-offshore breeze (323 energy), again small but workable.
Beyond that, the second week is pretty quiet. A few clean but tiny glimpses on the morning of 28 August – just 1ft SW groundswell (316 energy) with a light cross-offshore breeze – but honestly, it’s small enough to make you wonder if you brought the right board.
Overall, not much to get excited about. The water temp is sitting pretty average for this time of year – nothing unusual. Crowds are "sometimes" at The Groins, but with this lack of quality, you probably won’t be fighting for waves. If you’re desperate, keep an eye on that Thursday 20 August morning – it’s your best shot.
Rusty.
