The Lowdown
Alright crew, Rusty here. Let’s talk about Black Rocks Jetty. This reef break faces the SW, and the buoys are showing that’s exactly where the energy is coming from. Water temp is about 76°F, a touch warmer than average for this time of year, so you’ll be comfy in a shorty.
The first few days are slow but steady. The real highlight hits on Wednesday, September 9th. You’ll see a solid 12ft SSW groundswell with a very long period of 17 seconds, and dead calm, glassy conditions. The combined swell energy is around 8180 (strong), so this is a serious, powerful swell. This one’s for experienced surfers only – the size and the power will be too much for beginners. It’s the best session of the whole run.
Leading up to that, Saturday the 5th starts with a 5ft SW swell (14-second period) and a light cross-off wind from the NNW at 10 km/h, keeping it fairly clean (energy 1094). That afternoon turns glassy, dropping to 5ft. Sunday the 6th stays glassy all day with 4ft SW swell (13 seconds). Nice, clean little waves.
Monday the 7th gets bigger but sloppier. A 7ft SSW swell (15 seconds) on Monday morning turns choppy with a cross-onshore wind. Monday afternoon pushes to 8ft but it’s still messy. Tuesday the 8th afternoon delivers a 10ft SSW swell (15 seconds) with cross-shore winds, but it’s bumpy – a powerful option if you’re keen, but not the best.
After that standout Wednesday the 9th, the swell backs off but the quality holds. Thursday the 10th offers clean, glassy conditions with a 6ft SSW swell (14 seconds, energy 2484). Friday the 11th is smaller at 4ft and glassy again. The second week has a few onshore days, with rain showers on the 13th, but the morning of the 15th has clean 5ft SSW swell (16 seconds, energy 1526) that’s worth a paddle. The last few days around the 19th and 20th see clean glassy mornings but the swell drops right down to 3ft.
So to wrap it up: the absolute best session is September 9th for the big-wave crew. For everyone else, there’s plenty of good clean smaller surf on the 5th, 6th, 10th and 11th.
Rusty.
