The Lowdown

Alright, listen up. The next couple weeks around Little Austi and Main Beach are gonna test your love for the sport. We'll have a lot of flat, junky days before the ocean decides to put its game face on.

The start of the window is a total no-go. Wednesday the 9th and Thursday the 10th are tiny and choppy, blown out by a fresh cross-onshore wind. You're looking at ankle-biters, not worth the effort. The energy is real weak (25-31).

We've got to grind through this flat, wind-blown patch. The weekend of the 13th and 14th sees a little pulse, but it's nothing to write home about. Swell gets up to maybe 4ft on Sunday afternoon, but the period is a woeful 5 seconds, so it's just fat and lazy. The cross-offshore wind will keep it looking clean, but the lack of punch is the problem. By Monday the 14th afternoon, we get some size, hitting 5ft, but the energy is still weak (134). It's water moving but without any real conviction.

The first real swell of the run hits on Tuesday the 15th. The energy jumps to 376 and the swell is 6ft, but it arrives from the SSE with a cross-onshore breeze, which is gonna completely chop it up. That's a day to watch from the sand, not paddle out.

It'll go quiet again for a few days. Clean and small through mid-week, with periods varying but no size or power. A few fun looking mornings will be just thigh-high slop.

Now for the real standout, and this is a long-range heads-up, is Saturday the 19th. This is when the ocean finally wakes up. We are looking at a solid 10ft on Saturday morning, with the combined energy going absolutely ballistic at 1930. The period is 10 seconds, but at that size, it's just raw power. This is strictly for the elite. It's way too big and, with a cross-onshore wind, it's going to be a heavy, lumpy mess. Saturday afternoon eases to 8ft, still well overhead and challenging. Don't go near it unless you're charging.

Sunday the 20th drops to a much friendlier 5ft and the wind goes cross-offshore. That's a far more manageable wave for the advanced surfer. Energy is still up at 482, so there's decent push. This is probably the best bet for a real session for the most people.

We'll see a slow fade into the following week, with a fun, clean pulse around Wednesday the 23rd and Thursday the 24th. There's a clean 3-5ft forecast with light winds, and energy is building again (306-317). The period gets out to 10-11 seconds on Thursday, which should give a bit more shape. Not epic on the 23rd, but the morning could be super fun on the lower tides.

So, if you're picking your days, the big swell on the 19th is the main event for the experts only. For the rest of us, keep an eye on the morning of the 20th and later on the 24th for the best of the rest. Don't get excited about anything before that.
