The Lowdown

G’day, Rusty here. Look, we’ve got a bit of a flat spell on our hands for the next few days, but there’s a good pulse of swell heading our way that’ll fire up the weekend and beyond. Little Austi and Main Beach is our only break on the radar, so let’s get into it.

The first few days, Tuesday the 28th through to Friday the 31st of July, are a write-off. Tiny, weak swell – we’re talking 0.3ft to 1ft – with messy wind and next to no energy (combined energy values between 2 and 15). Not worth paddling for. A bit of a bummer, but it’s a short-lived lull.

Saturday the 1st of August is where things start to turn. The morning is still flat with a 1ft swell from the SSE, but the wind goes glassy, which is a nice sign. By Saturday afternoon, it’s on. A clean 5ft SSE groundswell rolls in with a period of 10 seconds and moderate energy of 542. Glassy wind too. The water is sitting at 65°F, which is about 2°F warmer than usual for this time of year – a nice little bonus.

Sunday the 2nd of August is the standout. Morning sees a clean 5ft SSE swell, period 11 seconds, and a light offshore wind from the NW. Combined energy is a solid 526. This is the best on offer, with clean, well-shaped waves for the intermediate crew. The afternoon drops a little to 4ft but stays clean with a cross-off breeze. Crowds are possible at this spot, so get in early.

Monday the 3rd of August drops off quickly with a 3ft SE swell and onshore wind – conditions get messy. Tuesday the 4th is even smaller. A bit of a gap in quality.

Wednesday the 5th and Thursday the 6th of August look funky. Thursday morning brings a 8ft SSE swell, but it’s blown out by a cross-onshore wind, and the period is a short 9 seconds. The combined energy of 1210 is strong, but the wind kills it. Too big for beginners, and the chop is ugly. This setup might be more interesting for kite surfers than paddle-in surfers.

Friday the 7th of August is a sleeper. The morning is still a bit messy with a 6ft SE swell, but by the afternoon it turns glassy with a 6ft swell from the ESE. Period 9 seconds, combined energy of 804. The wind goes glassy, so expect very good surf conditions. The swell direction is off the optimum, but the quality of the conditions will make up for it.

Saturday the 8th of August is another standout. Morning glassy conditions with a 4ft SSE groundswell, period 12 seconds, and combined energy of 611. That’s a long-period swell, so it’ll have good shape and plenty of push, though it might wall up a bit at the beach break – best for the more experienced. The afternoon stays clean with a 4ft swell and a light cross-shore breeze.

Sunday the 9th of August is a solid drop-off. A 3ft SSE swell, clean morning with a cross-off wind, but the energy is lighter (267). Still a fun little session for a longboard. Monday the 10th of August is similar, with a 3ft E swell and a clean offshore wind, but it’s not going to set the world on fire.

From Tuesday the 11th of August onward, we’re back to small, choppy junk. Wind shifts onshore and stays that way, with swells under 3ft. A bit of a flat end to the outlook.

To wrap it up: Sunday the 2nd of August is your best bet for the whole period – clean, consistent, and great energy. Friday the 7th and Saturday the 8th of August are also worth a look, especially if you can sneak out in the glassy afternoons.

Rusty.
