The Lowdown
Alright, let’s get into it. This is Rusty.
Right off the bat, we’ve got a window here at Little Austi and Main Beach that’s a bit of a mixed bag. The first decent surf shows up on the morning of Wednesday, July 22. It’s a clean, 4ft ENE swell with a 10-second period, and the wind is a light cross-off from the west. The water is sitting at 65°, which is pretty normal for this time of year. There’s moderate wave energy behind it (238), so it’s not a massive push, but it’s workable and clean. This is the best you’ll see for the first stretch.
After that, things drop off pretty quick. Thursday the 23rd has a bit of swell but it’s small, and the wind picks up, making it less appealing. From Friday the 24th through to Friday the 31st of July, it’s mostly flat to tiny, with poor conditions. There’s a real gap there – nearly a week of nothing worth chasing.
Now, Saturday the 1st of August brings a jump in size – 7ft from the SE – but the period is a short 6-7 seconds, and the wind is cross-off, but it’s borderline for the average surfer. The energy ramps up to 348-440, but the quality is marginal. This is more of a challenge than a treat.
The next real standout lands on Monday, August 3. The morning shows a 2ft SE groundswell with a very long 14-second period, clean offshore wind from the WNW, and solid energy (234). The afternoon holds similar, with 3ft SE swell, 13-second period, and a light cross-off. The quality is good, and the wind is kind. That’s your pick of the second week.
Then, after a couple of flat days, we get a big spike on Thursday, August 6. This is a serious event – 15ft SSE swell with a 12-second period and massive energy (10,383). The wind is cross-off. This is massive, very heavy, and only for experts. The period is long enough to hold shape, but at that size, you’re looking at a paddle battle that’s not for the faint-hearted. The energy is extreme.
So, if you’re picking the one session to lock in, it’s Wednesday morning, July 22, for clean, fun waves. For the long-range promise, Monday, August 3, is the one to watch – good groundswell, clean wind, and quality on offer. The big stuff on August 6 is a spectacle, but only for the very experienced.
Stay safe out there.
Rusty.
