The Lowdown

Alright folks, Rusty here. Let’s have a proper look at what’s on the cards over the next couple of weeks. We’re focusing on Black Rocks Jetty, and it’s a bit of a slow starter, but there’s some serious firepower waiting for us if we’re patient.

The water is sitting at a balmy 77°F, which is a touch warmer than normal for this time of year – you’ll feel that little extra warmth on your skin.

The first real action worth getting out of bed for is on Saturday the 15th. Saturday morning sees a solid 6ft SSW groundswell rolling in with a very long 20-second period and moderate combined wave energy (3762). The wind is light and from the SW, which is onshore here, so it’ll be a bit bumpy and not ideal. But hold tight, because Saturday afternoon is where it gets good. The swell bumps up to 7ft from the SSW, still a long 18-second period, and energy jumps to 5264. More importantly, the wind swings to a light NNW, giving us a clean cross-off breeze. This is expert territory for sure – that size and power will demand your full attention.

Sunday the 16th is a gem. Morning brings a clean 8ft SSW swell from a 16-second period (3428 energy) and glassy conditions with a whisper-light WNW breeze. That’s as clean as it gets for experienced surfers. The afternoon turns even glassier with the wind going dead calm and a steady 7ft SSW swell. This is the kind of session you’ll talk about all week.

After that, we hit a bit of a lull. Monday the 17th drops right off to 4ft with a cross-to onshore wind, and it stays small and marginal through to about Friday the 21st. The energy drops below 1000, and you’ll be chasing little waist-high leftovers if you’re keen. It’s not a write-off – Thursday morning the 20th and Friday the 21st have some glassy 3ft to 4ft SW swell, but nothing to get excited about.

Then we get a proper weekend. Saturday the 22nd serves up a clean 5ft to 6ft SSW swell with glassy conditions in the morning. But the real standout, and I mean the standout of the whole outlook, is Sunday the 23rd. Both the morning and afternoon pump out a solid 12ft SSW swell with a long 17-second period and monster energy readings of 6879 and 6932. The wind is light and cross-off, leaving the surface clean and lined up. This is only for experts – at that size, it’s serious. The swell direction is a perfect match for this break. If you’ve got the skills, that Sunday is the day.

Monday the 24th still has plenty of juice with 8ft SSW swell in the morning, glassy and clean, but the afternoon gets chopped up by a stronger onshore breeze. Tuesday the 25th is smaller and messier.

Now, look ahead to Thursday the 27th. Another big pulse arrives with an 12ft SSW swell, a 17-second period, and 7070 energy, all under glassy morning conditions. This is another expert-only day, and it’s promising, but remember it’s over a week away, so keep an eye on the updates.

The weekend of the 29th and 30th settles back down to solid but manageable 5ft to 7ft SSW swell with glassy conditions most of the time. Good for experienced surfers who want clean waves without the huge, heavy sets.

Overall, the first few days are a slow burn, but Sunday the 16th and especially Sunday the 23rd are the absolute standouts. The long-period groundswell will mean better shaped waves and easier paddling between sets, but at Black Rocks Jetty, the size and power will keep the crowds to those who know what they’re doing. Expect crowds sometimes here, but when it’s this big, it thins out.

Stay safe, read the ocean, and I’ll see you out there.

Rusty.
