The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a pretty quiet stretch ahead for Little Austi and Main Beach. The next couple of weeks are looking like a mixed bag of small, weak swell and tricky winds, but there’s a glimmer of hope if you’re patient.
Right now, and for the first few days, it’s pretty flat. The swell is tiny, around 2ft to 2ft, coming from the ENE with a short period of 9 to 10 seconds. The combined wave energy is weak, sitting at just 52 to 54 (52-54). The water temp is sitting at 63°, which is pretty much bang on average for this time of year. Winds are all over the place – cross-off, onshore, glassy – but with this little swell, it’s hard to get excited. Thursday morning the 13th is surfable but very ordinary, and Friday morning the 14th is glassy but still with next to no energy.
A bit of a bump arrives on Sunday the 16th, with the swell jumping to 5ft from the SSE. But the period is a short, choppy 6 seconds, and the wind is onshore or cross-onshore, making it a messy, poor-quality affair. The combined energy jumps to 222 (222), but it’s wind-affected and not what you’d call clean. This runs through Monday and Tuesday – 4ft to 4ft from the ESE, but again, short period and rain showers, with the energy staying in the 140 to 170 range.
Then we hit a dry spell from the 20th to the 22nd. The swell drops right back to 4ft to 4ft, and the energy is moderate. Thursday the 20th morning is glassy, but it’s still small.
The real standout of the whole forecast is Saturday the 22nd. We’ve got a solid 4ft of ENE swell, with a period of 9 seconds – that’s groundswell territory, and it’s packing some decent energy at 261 (261). The wind is offshore from the NNW, first cross-off in the morning, then clean offshore in the afternoon. This is the best on offer, and it’s not even close. The break is a beach and reef setup, exposed to the ENE swell, and the direction matches the optimum. It’s fairly consistent, and while you might see a few others out, it’s worth the paddle. That afternoon session is the one to circle.
After that, the swell fades again. Sunday the 23rd has some leftover energy (216-204) but the wind gets stronger, and by Monday the 24th we’re back to tiny waves and onshore wind.
So, bottom line: the next two weeks are mostly a snooze, but lock in Saturday the 22nd for a proper session. The rest is small, short-period, and wind-affected. It’s a real waiting game.
Rusty.
