The Lowdown
Alright, mate, Rusty here. Let’s have a look at what the next couple of weeks have in store for us at Austinmer Beach.
Honestly, the next week and a half is looking pretty grim. We’ve got a stretch of small, weak, and messy surf that’s going to have you checking your phone more than the ocean. The first real chance of anything worth paddling out for doesn’t show up until Monday the 24th, and even that’s nothing to write home about. Before that, we’re looking at a lot of sub-3ft slop with periods all over the shop, and wind that’s mostly cross or onshore. The combined energy is weak for most of it, struggling to get past the 200s until that Monday. There’s a brief moment on Tuesday the 18th morning where it goes glassy, but the swell is tiny at 3ft, so it’s more of a longboard grovel than a proper surf.
The standout window really starts to build from Monday the 24th. The morning looks clean with a light offshore wind and a 4ft east-northeast swell. It’s not huge, but the conditions are right. And while the energy is moderate (222), the clean lines should make it feel better than the numbers suggest. That’s probably your best bet for that week.
But the real one to keep an eye on is Saturday the 29th. The forecast is calling for a solid 7ft northeast swell, and the energy jumps right up to 755, which is proper, strong stuff. Morning looks glassy with light winds. That’s a big day for the beach. However, at that size, it’s going to be handling some serious water and it’s going to be too much for the beginners. This is one for the experienced crew only. And since it’s a beach break, a long-period swell like that might close out a bit, but with 8-second period, it’s not a pure groundswell, so there could be some workable peaks. It’s a standout for size, no doubt, but it’ll be a handful. The water temp is right around 64°, which is about average for this time of year, so a good wetsuit is still the go.
So, if you’re keen, pencil in the morning of the 24th for a clean, small session, and be ready for the 29th if you’ve got the skills and the courage. The rest of the time, it’s a waiting game.
Rusty.
