The Lowdown
G'day, Rusty here. Let’s be straight up: the next week and a half is a write-off for Little Austi and Main Beach. There’s a long dry spell from now right through until the end of July, with only tiny, weak, or messy waves. We’re talking over a week of flat, poor conditions, and that’s just the way she goes sometimes around here.
The only real glimmer in this whole 16-day window comes on the morning of Saturday, 1st August. We’ve got a solid, moderate energy swell rolling in (493) from the SSE at 4ft, with a period of 10 seconds – that’s a nice groundswell, with clean lines. The wind is a light offshore from the WNW at 3 mph, so expect smooth, clean faces. This is the standout session of the outlook. It’s a beach and reef setup, and with that offshore wind and decent energy, it should offer some fun, rideable waves for the intermediate crew. Crowds are possible here.
There’s also a bit of a pulse on Sunday morning, 2nd August. It’s smaller at 3ft from the SSE (222), but with a light offshore from the NW at 3 mph, it’ll be clean again. Not the standout, but a solid option if you missed Saturday.
Don’t get too excited about the big 10ft SSE swell that shows up on Thursday, 30th July. That is expert-only territory at this break, and with onshore winds, it’ll be a messy, washing machine affair – honestly, more of a kite surfing setup than a paddle session.
Water temp is 65°, which is pretty normal for this time of year – nothing unusual going on there.
So, in short: sit tight, wait for the morning of Saturday, 1st August, and get on it. The rest is a whole lot of nothing.
Rusty.
