The Lowdown
Rusty here again, but in feet and knots for you imperial lot.
First week’s looking flat and frustrating. Tuesday morning, August 25th is the best early option: 2ft of WSW groundswell with a 17-second period – that’s proper long-period energy, so it’ll be offering some nice shape at the jetty. The wind is offshore from the south at 13 knots, keeping the faces clean. Water temp is 62°F, about average for the season. The combined energy is moderate (267). It’s small, but if you’re keen, that’s your window.
The rest of the week stays tiny – 2ft to 2ft – with mostly clean mornings, but the afternoons get chopped up by westerly breezes. The crowds are sometimes a factor here, but with surf this small, you’ll be solo. There’s a long gap of poor surf from Wednesday afternoon through the end of August.
Come the first week of September, Tuesday morning, September 1st brings a little pulse: 2ft at 14 seconds from the SSW, with a gentle offshore wind. The combined energy is moderate (288). Then the afternoon sees a 4ft swell with a terrible 6-second period – that’s junky and not worth paddling for.
The real standout is Tuesday morning, September 8th. We’ve got 5ft of swell from the WNW, with a 9-second period, and a light offshore wind from the south at 3 knots. The combined energy is strong (445). The conditions are clean, and that swell is solid enough to get some proper waves at the Groins. Best of the entire forecast.
Wednesday morning, September 9th is also a goer – 4ft from the WNW at 10 seconds, glassy conditions, and combined energy of 490 (strong). The wind is light from the east, dead calm. Get out early because the afternoon turns to chop.
The Sunday before, September 7th, has 5ft of swell but a fresh cross-shore wind at 16 knots – that’s lumpy and choppy, better for kite-surfing.
First week is a write-off. Second week, Tuesday the 8th and Wednesday the 9th are your best shots. Go get it.
Rusty.

Further information to help with frequently asked questions about our surf forecast for Westport-The Groins may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
