The Lowdown

Right off the bat, it’s looking pretty gutless out at Little Austi and Main Beach. We’ve got a long stretch of small, weak surf on the cards, and to be honest, the first proper pulse of energy doesn’t even show up until over a week out. The water temp is sitting at 64°, which is about average for this time of year, so no surprises there.

The opening days are a real struggle. Thursday the 6th has a tiny 1ft easterly dribble with a cross-shore breeze, just a mess. Friday the 7th is a little better, with a cleaner 1ft wave and a cross-offshore wind, but it’s still pretty ordinary. Saturday morning the 8th is the first real highlight of this whole run – the wind goes glassy, dropping to 3 mph, and there’s a knee-high 1ft wave. It’s tiny, but it might be the cleanest it gets for a while, so if you’re desperate for a slide, that’s your window.

The swell finally shows some signs of life on Sunday the 9th, with the energy jumping up. We see 3ft in the morning, and then it pushes to 5ft by the afternoon as the energy climbs to 425. The wind is cross-offshore, so it’s clean, but the period is only 9 seconds, so it’s not got a lot of punch. Monday the 10th keeps that size, with 5ft in the morning, but the wind is howling offshore at 15 mph, making it a bit tricky. By the afternoon, the wind cranks up to 22 mph and the swell drops back to 3ft, which is a mess.

Then we hit a flat spell. From Tuesday the 11th all the way through to Friday the 14th morning, it’s just tiny 0.6ft to 2ft slop. Not worth paddling out for. The energy is in the 30s and 40s, which is about as weak as it gets.

But hold on. Friday afternoon the 14th is where things get interesting. The swell direction swings around to the SSE, and the size jumps to a solid 12ft. The energy reading is massive – 2639 – so there’s a lot of water moving. But the period is 11 seconds, and it’s a beach and reef setup, so this could be a bit of a beast. This is proper expert territory, way too big and powerful for the average punter. The following days see the swell ease off, but it’s still 8ft on Saturday the 15th with a strong cross-onshore wind, making it lumpy and pretty nasty. The rest of the second week is just a downward slide into chop and onshore slop, with a few small clean windows on the 20th and 21st, but nothing that’s going to get the heart racing.

So, the standout is Friday the 14th afternoon. It’s a real beast, but it’s a long way off, so treat it as promising but not set in stone. The other little window is Saturday morning the 8th, if you just want a fun, clean knee-high wave. Don’t hold your breath for much else.

Rusty.
