The Lowdown

Alright folks, Rusty here. Let’s get into it for Little Austi and Main Beach.

Honestly, looking at the whole 16-day window, this is a tough stretch. There’s a big gap of almost nothing at the start. We’re talking about days with waves so small they’re barely a ripple. Tuesday the 8th has a tiny 0.7ft easterly swell with a long 11-second period, but the wind is messy and cross-onshore, so it’s a no-go. The afternoon sees a bit of a pulse jump to 7ft from the SSE, but the energy is high (559) and the wind is onshore, making it a choppy, marginal mess. That’s not worth paddling out for.

From Wednesday the 9th right through to Saturday the 12th, it’s all poor surf. Swell sizes are tiny, mostly 0.7ft to 1.0ft, and the wind is either cross-on or straight onshore. The surf is just a total write-off. The combined energy readings are all in the double digits, which is weak, weak, weak.

The pattern only starts to show a little life on Sunday the 13th. The morning stays clean with a light north breeze, but the swell is a pathetic 1ft with a short 5-second period. By the afternoon, there’s a 3ft swell from the NE, but the period is a super short 4 seconds. The wind is cross-off and clean, and the energy is a weak 64. It’s surfable, but very ordinary. The best chance of a clean wave in this whole period might be Monday the 14th afternoon. The swell is 3ft from the NE, still short period, but the wind goes glassy at only 3 mph. The water is clean, but the waves are small and weak. The combined energy is a measly 38.

After that, we get a few more days of poor surf peppered with tiny, short-period pulses. The wind is often clean, but there just isn’t any swell to work with. The water temperature anomaly is about average for this time of year, so no worries on that front.

The only slight glimmer of hope comes around Friday the 18th afternoon. We get a 3ft SSE swell with a 10-second period, and the combined energy jumps to 245. That’s moderate energy. The wind is a light cross-shore, which is okay, but the conditions are still described as marginal. Saturday the 19th morning could be your best bet, with a 3ft SSE swell, a 9-second period, and a moderate offshore wind from the NNW keeping it clean. The energy is 132, which is moderate. It’s still just surfable, very ordinary conditions.

For the second week, it’s more of the same: small waves, clean winds, but nothing that gets the heart racing. The 3ft NE swell on the 23rd with a 6-second period is about as good as it gets, and that’s saying something.

The wind is mostly cross-off or glassy on the mornings, so the conditions will be clean, but the swell is just too small and weak to offer any real power. The break is a beach and reef setup, and with the long stretches of poor surf, I’d say this is one of those times where the forecast can change, but as it stands, it’s a flat spell.

Rusty.
