The Lowdown
G’day, I’m Rusty. Let’s have a look at what’s coming up for Little Austi and Main Beach.
To be straight with you, the forecast is a bit of a dry spell for a while. The first real chance of anything that could be called surf shows up on Friday the 11th, and even then it’s barely hanging on. For almost a week before that, from Thursday the 3rd right through to Thursday the 10th, it’s all poor surf conditions with tiny, weak swell and mostly messy wind. A lot of those mornings have clean conditions, but with swells barely cracking 1ft to 2ft and combined wave energy sitting under 60 (34 to 57), there’s just not enough push to bother paddling out.
Friday the 11th morning is where things finally tick over a little. There’s a pulse of groundswell from the SSE at 4ft with a very long period of 12 seconds. That’s a lot of energy for this setup – combined energy hits 516 (strong wave energy). The wind is light cross-onshore from the ENE at only 3 mph, keeping things reasonably clean. That said, with that long period, the swell might wrap a bit too straight at a beach-and-reef break like this, but if you’re an intermediate and keen, it’s your best window in the whole run. The water temp is about average for this time of year.
Saturday the 12th morning offers surfable but ordinary conditions with a 3ft NE windswell, period of 6 seconds, and a light cross-offshore breeze from the north at 6 mph keeping it clean. Combined energy is weak at 65. It’s not a standout, but if you’re desperate for a paddle, it’s doable. The afternoon bumps up to 4ft but the wind picks up to 12 mph and the period drops to 5 seconds, making it messy.
Beyond that, Sunday the 13th to Wednesday the 16th stays small and average, with most sessions offering little more than knee-high dribble. The best of those is Sunday afternoon with a clean moderate offshore from the NW at 12 mph and 2ft swell, but combined energy is only 53.
If you’ve got a kite, some of those breezy afternoons might look more interesting than paddle surfing – especially Saturday the 12th and Sunday the 13th afternoons. For a surfer, Friday morning the 11th is your one real chance.
Rusty.
