The Lowdown

G’day, Rusty here, checking in on the local stretch. We’ve got a bit of a mixed bag coming up over the next couple of weeks, but there’s a few windows that’ll get the blood pumping.

Right off the bat, the best bet is Monday morning, August 3rd, at Little Austi and Main Beach. The water’s sitting at 64° – that’s pretty much spot on for this time of year, so nothing to worry about there. We’ve got a solid 3ft swell rolling in from the SE, with a nice 11-second period – that’s proper groundswell, meaning good energy and clean lines. The wind is light out of the NW at 9 mph, keeping it offshore and glassy. The combined energy is sitting at 226 (moderate), so there’s a bit of push behind it. This is the standout for the whole forecast – clean, surfable, and with that offshore breeze, you’ll be stoked.

Monday afternoon drops off a touch – 3ft from the SE, still with that 11-second period, but the wind goes light and offshore at 6 mph. It’s still clean, but the size is backing off. Worth a paddle if you missed the morning.

Then we hit a dry spell. From Tuesday, August 4th, right through to Saturday, August 8th, it’s pretty grim. The swell drops to nothing – 2ft and smaller – and the winds are all over the place, mostly cross-off or cross-on. The energy is weak (as low as 12), and the wave comment is “poor surf conditions” every session. It’s a full five days of junk, so don’t bother getting your hopes up.

Sunday, August 9th, things start to look a little more interesting. The morning brings a 4ft NE swell with a short 7-second period, so it’s a bit choppy and disorganised, but the wind is offshore from the NNW at 9 mph. The combined energy jumps to 151 (moderate), and while it’s only rated as “surfable but very ordinary,” it’s a step up from the week before. The afternoon holds similar conditions with 4ft and offshore NW wind at 12 mph, but the period is still short. Not a classic, but if you’re desperate, it’s the best of a bad bunch.

Monday, August 10th, sees the swell drop back to 3ft from the ENE, with a moderate 9-second period, but the wind is cross-off from the WSW at 12 mph, keeping it clean. The energy is 117 (moderate), but it’s nothing to write home about. The rest of the week is more of the same – small, weak, and mostly cross-shore winds. There’s a glassy moment on Tuesday morning, August 11th, with 2ft ENE swell, but the energy is only 50 (weak), so you’ll be scratching for a wave.

The second week, from August 12th onwards, is pretty quiet. The swell stays small, mostly under 3ft, and the winds are mostly cross-off or cross-on. There’s a couple of glassy mornings on August 17th and 18th, with 2ft and 2ft ENE swells, but the energy is weak to moderate (116 and 87). The period on the 17th is 10 seconds, so there’s a bit of shape, but it’s nothing to get excited about.

In short, the whole forecast is pretty average. The only real standout is Monday morning, August 3rd – that’s your window. After that, it’s a long wait for anything half-decent, and even then, it’s just surfable, not epic. If you’re a beginner, the 3ft to 4ft days are fine, but anything over 5ft isn’t on the cards. The beach-and-reef setup here means it handles a bit of everything, but with the small swell and inconsistent energy, it’s more of a kite-surfing setup than a paddle-surfing one on the bigger wind days.

Signing off, Rusty.
