The Lowdown

G'day, Rusty here, and I've been staring at the charts for Black Rocks Jetty. This is a reef break, very consistent, and it's exposed to the southwest swell. The water temp is about average for this time of year. We've got a solid run of good to excellent surf coming, but it's mostly for experienced surfers, so keep that in mind.

It kicks off this Saturday, 29th August, with a real beast. A solid 12 ft SSW groundswell, with a very long 15 second period – that's a heap of energy (4900) and it's pushing in with glassy conditions. That's a proper stand-out session for the crew who can handle it, but it's a deep-water reef, so that long period will wrap in nicely. The morning is the pick with light winds, but the afternoon holds the same quality. The swell stays strong on Sunday the 30th, with a 8 ft SSW swell and 14 second period, still glassy in the morning. Energy is still high (2048). The wind shifts a little in the afternoon, making it a bit more ordinary.

Monday the 31st is still a good call, with the swell dropping to a clean 5 ft from the south, 12 second period, and glassy conditions. The wind stays light all day. The energy is a more moderate 574. After that, the surf drops right off into the first few days of September. From Tuesday the 1st through to Friday the 4th, it's pretty flat. There are some tiny waves, but nothing worth paddling out for. It's a definite gap of a few days with no real recommendations.

We get a pulse back on Saturday the 5th of September, with a 4 ft SW swell, 14 second period, and glassy morning conditions (565 energy). That's a nice little window. Then Sunday the 6th serves up a 3 ft SSW groundswell with a very long 17 second period, and the energy jumps to 1005. It's glassy, and that long period will be a treat on the reef. The real standout of the second week, though, is Monday the 7th of September. We're back to a 10 ft SSW swell, 15 second period, and a massive 3783 energy reading. Glassy winds in the morning – that's a day for the advanced crew only. The swell is well over 8 ft, so it's expert territory.

The following days are all over 6 ft, with solid periods, but the wind gets tricky. Tuesday the 8th has a 7 ft S swell, 16 second period, and glassy in the morning, but the afternoon turns into a clean 10 ft SSW swell with 19 second period – that's a very long period groundswell – and a cross-off breeze. The energy is through the roof at 6055. It's a high-quality option, but you need to be on your game. The wind stays cross-off through the 9th and 10th, with waves in the 6-8 ft range. Then from Friday the 11th, the wind turns onshore and the sea gets choppy, with solid 8 to 10 ft south swells, making it messy and unappealing. The energy is still huge, but it's blown out. That run of poor conditions carries through the weekend of the 12th and into the 13th.

So, the real pick of the whole forecast is the first Saturday, 29th August, with that massive, clean swell. For the second week, the morning of Monday the 7th September is your best bet for another big, clean session. The rest of the time is either too small, blown out, or just for the die-hards.

Rusty.
