The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for the next couple of weeks.
Honestly, the first week or so is a real struggle. We’ve got a long stretch of tiny, weak, and messy conditions that just aren't worth paddling out for. From Friday the 24th of July all the way through to the end of the month, we’re looking at poor surf with swell heights barely cracking 2ft and short, weak periods. The wind is mostly cross or onshore, keeping things choppy and uninviting. You’re looking at about a week of flat, frustrating conditions.
Now, we finally get a bit of a pulse coming into the first weekend of August. The morning of Saturday the 1st of August brings a glassy start with a 3ft SSE swell, period around 10 seconds. The combined energy is moderate at 196, and it's glassy, which is a major positive. It’s surfable, but very ordinary. The afternoon gets a bit bumpy with a cross-shore breeze. Sunday the 2nd is similar – clean in the morning with a 2ft SSE swell (122 combined energy) but nothing to write home about.
The real standout, the one you’ve been waiting for, is shaping up for the second week. Mark your calendars for the morning of Thursday the 6th of August. This is where it gets exciting. Little Austi and Main Beach will see a solid 8ft swell from the SSE, and with a period of 8 seconds, it’s packing some serious punch. The combined energy is a massive 1057, which is strong. The wind is glassy, absolutely dead calm, which means the waves will be clean as a whistle. This is excellent surf, but at 8ft, it’s strictly for the experienced crew. Beginners should sit this one out.
Following that, Friday the 7th of August morning is also a beauty. A 6ft ENE swell with glassy conditions (761 combined energy) will deliver very good waves. The afternoon stays clean with a nice cross-offshore breeze on a 6ft ENE swell (537 energy). These are both excellent days.
Looking further out, the morning of Saturday the 8th of August is the big one. A massive 13ft ENE groundswell with a long 12-second period is forecast. The combined energy is a whopping 4748, which is very strong. The wind is light and cross-offshore, promising clean, powerful waves. This is expert-only territory, but for those who can handle it, it’s going to be spectacular. Keep in mind, with a period that long, the sets will be spaced out, and it might be a bit too straight for a beach break, but on a good bank, it’ll be magic.
Rusty.
