The Lowdown

G’day, Rusty here. We’ve got a solid run of surf ahead at Black Rocks Jetty, kicking off from this Sunday morning and rolling through most of the next two and a half weeks. The overall pattern is one of consistent, clean south-west groundswell, with a couple of real standout days that’ll have you grinning ear to ear. The water temp is sittin’ about average for this time of year, so no surprises there.

Let’s start with Sunday the 9th of August – morning brings in a clean 4ft south-west swell, dead glassy with combined wave energy at 618 (moderate). It’s a reef break that’s very consistent and exposed to the swell, so you’ll find nice lined-up waves. The afternoon turns a bit onshore with 6 mph winds, so the quality drops – gets a bit choppy and questionable.

Monday the 10th keeps the same size and direction, 4ft south-west, glassy again in the morning with energy bumpin’ to 677 (moderate). Afternoon gets rainy and cross-on, so morning is your window.

Tuesday the 11th – morning glassy at 4ft south-west, 676 energy, real nice. Even the afternoon holds glassy with a slight shift to south-south-west wind, still clean. Wednesday the 12th follows suit: glassy all day, 4ft south-west, moderate energy – just consistent, fun waves.

Thursday the 13th – a little smaller at 4ft to 4ft south-west, still glassy, but the energy drops to 357–580 (moderate). Good for a cruisy session.

Now, Friday the 14th of August is where things start to fire up. The swell pushes to 6ft from the south-south-west, period at 13 seconds, and combined energy jumps to 1254 (strong). Glassy all day, clean as a whistle. This is excellent for experienced surfers – a bit too big for beginners. The direction is a touch south of optimum, but the quality is undeniable.

Saturday the 15th of August is the first true standout. Morning sees a 5ft south swell with a 20-second period – that’s very long-period groundswell, real energy at 3322 (very strong). Glassy conditions. This kind of long-period swell can break a bit straight at beach breaks, but on a reef setup like Black Rocks Jetty, it’ll hold up nicely. Afternoon brings a jump to 8ft south-south-west, 18 seconds, and energy at 5137 (very strong) – but the wind goes cross-shore and the tide gets questionable, so the morning window is the pick.

Sunday the 16th of August is another standout. Morning is 8ft south-south-west, 16-second period, glassy, with energy at 3317 (very strong). This is expert territory – too big for most, but if you’ve got the skills, it’s going to be epic. Afternoon drops to 7ft, still glassy, still excellent.

Monday the 17th – size drops to 4ft south, cross-on wind in the morning, but afternoon turns glassy with 4ft south and energy at 1067 (strong). Good session if you’re flexible.

From Tuesday the 18th through to Friday the 21st, the swell backs off – 2ft to 3ft south-west to south, all glassy or clean, with energy ranging from 184 to 502 (weak to moderate). Not big, but still fun for a small-wave board.

Saturday the 22nd of August – another solid day. Swell builds to 5ft from the south-south-west, 16-second period, offshore winds at 9 mph from the north-north-east, energy at 1353 (strong). Clean and punchy – a great day for a paddle.

Sunday the 23rd of August is the second true standout. Morning brings 8ft south-south-west, 15-second period, glassy, with energy at 2754 (very strong). This is big, clean, and powerful – experts only. Afternoon holds at 8ft, glassy, still excellent.

Monday the 24th of August – swell drops to 6ft south-south-west, glassy, energy 1294 (strong). Still a very good session to wrap up the run.

Crowds at Black Rocks Jetty can be an issue sometimes, but with all this quality on offer, expect company on those standout days. The spot is very consistent, so there’s rarely a dull moment.

Rusty.
