The Lowdown

Alright, let me tell you what's cookin' for the next couple of weeks.

Honestly, I gotta be straight with you – it's a tough stretch here at Little Austi and Main Beach. The first week is pretty much a write-off, with barely a ripple. We're looking at a solid 10-day gap with no real surf to get excited about. Don't get too down, though; it won't stay this way forever.

Come Thursday, the 31st of July, we see a bit of a pulse. A strong cross-shore storm swell pushes in, sending 8ft waves from the SSE with a period of 11 seconds. The combined swell energy is a heavy 1485, but the wind is howling at 25 mph from the SW, making it a total mess. With that kind of wind and size, this setup is looking way more interesting for the kite surfers than for a paddle surfer.

Things settle down a bit for Saturday, the 1st of August. The swell drops to a more manageable 7ft from the SSE, with moderate energy (719). The wind is still a cross-shore from the SW at 12 mph, so it's a bit lumpy, but the tide might be a factor. The conditions are just marginal, and that's being generous.

Sunday the 2nd is a step down again, with 4ft SSE swell, but the wind turns cross-onshore, making it choppy.

Now, here's the one true standout in the whole forecast. On Friday, the 7th of August, we finally get a clean window. The morning looks promising with a 3ft swell from the ESE and a period of 10 seconds. The wind is a clean cross-offshore from the WSW at 9 mph, giving us clean conditions. The combined swell energy is a solid 280, so there's some push. This is the best chance all period to get a few clean ones without wrestling the wind. Just be aware that by the afternoon, the wind swings onshore and messes it up.

So, if you can wait it out, that Friday morning on the 7th is your best bet. Otherwise, it's a long wait for very little.

Rusty.
