The Lowdown
Alright mate, Rusty here. Let’s have a proper look at what’s on the table for the next couple of weeks.
To be brutally honest, this is one of those stretches where you might want to leave the board in the car and just enjoy a coffee on the beach. We’ve got a long, quiet run ahead. The first real whisper of anything rideable doesn’t pop up until the morning of Tuesday the 25th of August, and even then it’s nothing to write home about. From now until then, it’s a total flat spell – tiny slop, no energy, no hope. We’re talking a solid 10-day gap with zero recommendations.
Now, when we finally get a pulse, it’s Triggs Beach (Adelaide) that shows the only flicker of life. It’s a sheltered reef break, pretty inconsistent, and only for beginners at the best of times. The water’s sitting at 57°F, which is about normal for this time of year – nothing out of the ordinary.
On Tuesday the 25th, we see a spike in the morning: a 6 ft swell from the northwest, with a short period of 6 seconds. The combined energy hits 195 (moderate), but the wind is a gentle cross-shore from the north, so it’ll be a little bumpy. Not great, but it’s the biggest we get.
The standout – and I’m using that term loosely – is Thursday the 27th of August. Morning brings a 5 ft swell from the southwest, period of 6 seconds, and the combined energy is 159 (moderate). The wind is a light offshore from the east-northeast, only 3 mph, so the surface will be clean. The water’s still around 57°F, and this is the only window that’s even close to surfable. It’s not going to blow your mind, but if you’re desperate, this is your best bet. That afternoon, though, the wind swings cross-onshore and the quality drops right off.
After that, it fades back into tiny, weak dribble through to the end of the month. Nothing else worth paddling out for.
So, yeah. One morning, one spot, and a whole lot of sitting around. That’s the story.
Rusty.
