The Lowdown
Alright folks, Rusty here. Let's have a look at what Little Austi and Main Beach has cookin' for us. This is a beach and reef setup.
Alright, straight up, the next 16 days look pretty flat and ordinary most of the time. We've got a long stretch of nothing really happening. The first clue of any real surf doesn't pop up until Monday the 7th, and even that’s nothing to write home about. There are long gaps of poor conditions, especially from now through the weekend, with only small, weak waves and sketchy winds.
The first little blip of interest comes Monday morning the 7th. We've got a 3 ft swell from the SSE with a 9-second period, and a northwest wind blowing offshore. That’s clean, and the combined energy shows a bit of life at 161 (moderate). It’s not big, but it’s the first clean wave of the period.
Then it gets real ordinary again until Wednesday afternoon the 9th, where the swell starts building. By Wednesday afternoon, the swell hits 5 ft from the SSE (8 seconds), but it's cross-onshore from the south at 12 mph, making it choppy. The energy jumps to 373 (strong), but the wind is a problem.
For a standout, you’re looking at Thursday the 17th – that’s over two weeks away, so keep the salt in your pocket until we get closer. The morning shows 6 ft from the NE with an 8-second period. It’s cross-onshore with light rain, but the combined energy hits 698 (strong). That’s the biggest push of the whole 16-day run. At 6 ft, it’s getting into that intermediate zone, maybe a bit much for beginners. The water temp is around 64°F, which is about average for the time of year – nothing weird going on there.
Nothing in this whole window is a screaming winner. The only one that really stands above the rest is that Thursday the 17th morning session, if you’re happy to wait and the wind co-operates. Keep an eye on it.
That’s the book on it. Keep your stick wet, even if it’s just a splash.
Rusty.
