The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer at Westport-The Groins.
Right off the bat, the next couple of days are pretty ordinary. Tuesday the 18th and Wednesday the 19th are just surfable, with mixed energy and a bit of wind messing things up. Not worth getting excited about.
But then, Thursday morning the 20th is where it gets interesting. The swell picks up to 4ft from the WNW, with a period of 11 seconds. The real kicker is the glassy wind – that’s rare and it’s going to make the waves clean as a whistle. The combined energy is moderate (506), so there’s some push behind it. This is the standout of the whole run. Not massive, but with that offshore glass, it’ll be the best you’ll see. The water temperature is about average for this time of year, so no surprises there.
After that, Friday the 21st has some clean-ish offshore wind in the morning with 3ft from the WNW, but the period drops to 8 seconds, so it’s a bit weaker and less organised. The energy drops too (261). Still, it’s rideable. Saturday the 22nd through to the end of the month gets pretty grim – mostly poor conditions with cross-onshore winds and choppy surf. The swell sticks around, but the quality is just not there.
There’s a bit of a gap there where nothing is worth a paddle. Then, the last few days of the month and into September, there’s a faint glimmer. Saturday morning the 29th has some clean offshore wind with 2ft from the SW and a long 16-second period, combined energy at 328 (moderate). It’s surfable, but not a standout. Sunday the 30th is similar, and Monday the 31st also has light offshore winds. That’s about as good as it gets in that second week.
To be honest, Thursday the 20th is your best bet. If you can get out then, you’ll be stoked. The rest of the run is mostly waiting for the wind to play nice.
Rusty.
