Righto, Rusty here. Let's have a look at what's comin' down at Little Austi and Main Beach.
We're lookin' at a proper mixed bag over the next couple of weeks. There's a bit of a slow start, but there is some size on the way, though the wind's gonna be a constant battle. The water's sittin' at 66°F at the start, which is a touch warmer than normal for this time of year—nothing crazy, just a little extra warmth in the water.
The first real surfable day is Tuesday, July 7th. It's not a standout, but it's the first sign of life. We've got a solid 8ft SSE swell rolling in, with a moderate wave energy building (1978). The period's a middling 10 seconds, so it's got a bit of punch. The wind is a cross-shore from the SSW at 9 mph, keeping things a little lumpy but ridable. This is expert territory at this size, well over the 8ft mark on the Thursday morning, so if you're not confident, give it a miss.
The real standout of the whole outlook, and the only time I'd get properly excited, is Saturday, July 11th in the afternoon. We get a drop in size to 4ft from the SE, but the wind goes glassy. Completely glassy. That's about as good as it gets for clean conditions. The wave energy is a moderate 272, and the period is a short 9 seconds, so it'll be a bit more playful and less of a grind. This is your window for a clean, fun session without getting blown off ya board. Crowds are *sometimes* a problem here, so on a glassy weekend arvo, you might have to share.
Before that, there are a few days of 8ft+ swell but with cross-onshore winds that'll make it a messy, choppy mess. That Monday, July 6th, has a decent 8ft swell and an onshore wind—honestly, that setup looks more interesting for a kite surfer than a paddle surfer.
After that Saturday glass-off, it fades fast. The next week is a write-off with tiny, poor waves and strong winds. There's a gap from Sunday, July 12th through to about Friday, July 17th where there's nothing worth paddling out for. A real dry spell.
So, bottom line: if you can only pick one session, make it Saturday, July 11th, for the afternoon glass-off and clean 4ft waves.
Rusty.
