Updates in hr min s Forecast update imminent
Alright folks, Rusty here. Let's have a look at the local stretch, Little Austi and Main Beach.
We’ve got a bit of a wait ahead for anything decent, I’m not gonna lie. The first week or so is pretty much a write-off, so don’t get your hopes up for the next several days. The water temp is sitting at 65°, which is about average for this time of year, nothing to get excited about.
The first real glimmer of hope arrives on Saturday the 11th of July. We finally get a break from the cross-onshore junk. Saturday morning is looking clean with a light offshore wind from the NW and a small 4ft SE swell. The conditions will be smooth, but keep your expectations realistic – the wave energy is modest at 383.
The standout, and I mean the standout, is the Saturday the 18th of July. This is the one to circle on the calendar. It's over a week out, so treat it as a promising long-range call, but it looks bloody lovely. Glassy conditions, calm wind, and a clean 6ft SSE swell rolling in. The wave energy is up at 559, which will give it some push. For Little Austi and Main Beach (beach and reef), that combination of glassy water and a solid 6ft swell should produce some nice clean lines. It's a moderate size, but not too big for the average surfer. If you can, get on it.
Because the easterly angle lines up nicely with the spot’s optimum ENE direction, the swell will wrap in well. Just be aware, as a beach and reef setup, it can get a little tricky with the larger sets, but the glassy wind will make it all worthwhile.
For the rest of the period after that, Sunday the 19th has a small, clean 3ft wave with a light offshore, but it's nothing special. Then it drops right off into tiny and messy conditions through the final days. There's a big empty gap of flatness before that Saturday the 18th, so don't bother checking the cams until then.
In short, it’s a slow burn, but that Saturday the 18th is the real deal.
