The Lowdown
Alright, Rusty here. Let’s talk about Black Rocks Jetty.
The first good surf hits on Sunday, the 23rd of August. We’ve got a 7ft SW groundswell with a 14-second period, and the combined energy is at 1895 – that’s strong. Wind is dead glassy, so the surface is clean as a whistle. But this is reef, and at 7ft, it’s for experienced surfers only. The water temp is 77°, a touch warmer than usual.
Monday the 24th keeps it going with a 7ft SSW groundswell, 15-second period, and morning offshore wind from the NNE. Energy jumps to 2368. Afternoon goes glassy again. Both sessions are expert-only.
Tuesday the 25th brings a 5ft SSW swell, 13-second period, with glassy morning conditions and clean cross-offshore in the afternoon. Solid quality.
Wednesday the 26th: morning has 5ft SW swell with clean cross-offshore wind. The afternoon drops to 3ft but the period stretches to 18 seconds – very long period, which is best on a reef. Still, it’s small.
Thursday the 27th is a write-off. Swell jumps to 8ft in the morning and 10ft in the afternoon, but the wind is onshore and strong. Choppy and messy.
Friday the 28th is the standout. Morning delivers a 13ft SW groundswell with a 16-second period and cross-shore wind. Energy is at 7271 – massive power. This is for experts only. Afternoon drops to 12ft but still holds 6385 energy.
Saturday the 29th: 10ft SW swell in the morning, dropping to 10ft in the afternoon, but the afternoon turns glassy. Clean and powerful.
Sunday the 30th: 7ft in the morning, 6ft in the afternoon, both glassy. Good clean surf for experienced surfers.
From Monday the 31st, it drops fast. By Tuesday the 1st of September, we’re at 2ft, and it stays small and weak through the 2nd and 3rd. There’s a stretch of several days with no real surf to recommend – from the 1st through the 7th, it’s mostly poor or marginal. A little pulse on the 7th with a 4ft SSW swell, but nothing special.
Best on offer: Friday the 28th for the big wave crew – 13ft SW groundswell with 16-second period. And Saturday the 29th for the glassy afternoon with 10ft of clean swell.
Rusty.
