The Lowdown
G’day, I’m Rusty. Let’s dig into what’s coming up at Black Rocks Jetty.
The water temp is right around average for the season, nothing weird. The first couple of days are messy, but we’ve got a couple of proper windows to get excited about.
Monday the 7th is a total dud—7ft to 8ft of SSW swell with cross-onshore wind and choppy junk. Not worth wetting a wetsuit.
Tuesday the 8th shapes up. Morning sees 7ft SSW, light cross-shore, and the energy is solid. But Tuesday afternoon is where it’s at: 10ft SSW, light cross-shore, and clean enough to get your heart rate up.
The big one is Wednesday morning the 9th. Glassy, 12ft SSW, 17 second period—this is long-period groundswell with a heap of punch. For a reef setup like this, that’s a proper treat. Definitely for experts only at that size. Energy is through the roof. That’s the session of the fortnight.
Thursday the 10th stays glassy—7ft SSW easing to 5ft SW—still good for experienced surfers.
From Friday the 11th through Sunday the 13th, the swell drops to 3ft to 6ft, mostly glassy, with long periods. Clean but small.
Monday the 14th turns bumpy again with cross-onshore wind. Tuesday the 15th cleans up nicely, glassy afternoons with 6ft SSW—real nice.
Saturday the 19th and Sunday the 20th are looking good: glassy, 6ft to 7ft SSW, clean and consistent. Monday the 21st has 10ft S swell with glassy afternoon conditions—big and clean for the crew who can handle it.
Best surf? Wednesday the 9th—glassy 12ft groundswell. Second pick is Tuesday afternoon the 8th, with 10ft and clean lines. Crowds can pop up here sometimes, so pick your moment.
This is Rusty, out.
