The Lowdown

G’day, Rusty here. Let’s look at what Little Austi and Main Beach has in store.

It’s a quiet start. The first time you’d even think about paddling out is Thursday 13th, but it’s nothing special. The water temp is 64°, right about average for the season.

Thursday 13th morning has a tiny 2 ft swell from ENE with a 10-second period. Light WSW wind keeps it clean, but there’s almost no power.

Friday 14th morning is glassy with a 1 ft, 10-second ENE swell – rideable but weak.

Saturday 15th is a total dud – onshore wind and tiny waves.

From Sunday 16th through Wednesday 19th, the swell picks up to 6 ft–6 ft from SSE and ESE, but it’s all onshore with rain showers. Choppy and ugly – better for kite surfing.

Thursday 20th drops to 3 ft with light wind, but still cross-onshore.

Friday 21st morning is the first clean session – 3 ft ENE groundswell with a light offshore breeze. Not epic, but you could get a few.

Saturday 22nd morning is the real standout. Expect good surf: 3 ft from the ENE, clean with a light WSW offshore wind. Energy is solid. The crowd factor is only sometimes, so it might be quiet. That’s your best bet.

Sunday 23rd brings a big 6 ft–7 ft NE swell, but cross-onshore wind messes it up – only for experts, and even then it’s not pretty.

After that, it fades into small, onshore junk through to Wednesday 26th. One glassy morning on the 26th, but with a short-period 3 ft SSE swell that’s only ordinary.

So, mark Saturday 22nd morning on your calendar. That’s the one.

Rusty.
