The Lowdown

Alright, Rusty here. Let's get into it.

First up, we’ve got a solid run of swell on the cards for Black Rocks Jetty, a reef break that’s very consistent and handles a south-west swell perfectly. The water is sitting at 77.2°F to start, which is much warmer than normal for this time of year – a solid 4°F above average, so the boardies are the go.

The week kicks off on Wednesday, August 26th with a glassy 3.0ft south-south-west swell, long period of 18 seconds. The energy is pumping (1185), and with the wind dead flat, it’s clean and inviting for anyone who knows their way around a reef. Not a standout but a nice warm-up.

The real standout window opens Thursday morning, August 27th. We’re looking at a solid 10.0ft south-south-west groundswell, period a very long 17 seconds, and glassy conditions. The energy is massive (4932) – this is powerful, clean, and demanding. This is a proper session for experienced surfers only; anything over 8.0ft is expert territory, and this is it. The wind is a whisper from the west-south-west, so it’s flawless. This is the best on offer in the whole outlook.

Thursday afternoon the wind swings cross-on and the quality drops, but the swell holds. Friday the 28th is blown out – strong cross-shore winds and lumpy 13.0ft surf – not worth the paddle. That said, Saturday afternoon, August 29th, glassy conditions return with a 10.0ft south-south-west swell, still a long period of 15 seconds. It’s excellent for those who can handle it, but the energy is still high (3932).

Sunday morning the 30th is glassy again with a 7.5ft south-south-west swell – still a big wave, but cleaner and more manageable than the 10.0ft days. The wind is off, so expect clean lines. The energy is dropping but still substantial (2078).

After that, the swell fades through the start of September. From Monday, September 1st, we’re into small, weak surf – under 3.0ft for days, with very low energy (down to 75). The conditions are often glassy, but there’s just not enough push. There’s a gap from the 1st through to the 4th where it’s really not worth getting wet.

Then, Saturday, September 5th afternoon shows a little pulse: 3.6ft south-west swell, calm and glassy, with energy picking up to 751. It’s a small window of very good, clean conditions. The next morning, Sunday, September 6th, is another glassy session with 4.6ft south-south-west swell, period 15 seconds, and energy back up to 1178. Clean, solid, and excellent for experienced surfers.

The second week rounds out with a few more promising days. Tuesday, September 8th, morning has light offshore winds from the north-east, a 5.2ft south-west swell, and clean conditions. The energy is strong (1414). Wednesday, September 9th, morning is the standout of the second week – a clean 8.2ft south-south-west groundswell, period 16 seconds, light cross-offshore wind, and energy hitting 3566. This is another big, powerful session for experts only. The long period means it’ll be a bit straight at the beach, but on a reef like this, it’ll be a proper ledge.

After that, the swell starts to ease again, but remains surfable through the 10th with a 6.6ft south-south-west swell and glassy conditions on Thursday morning.

Best on offer: Thursday, August 27th morning for the sheer power and perfection, and Wednesday, September 9th morning for a second helping of big, clean groundswell. Both are for experts only.
