The Lowdown
Alright mates, Rusty here. Let’s chew through what’s on the table for Black Rocks Jetty these next couple weeks.
First real wave of the run hits Tuesday, September 15th. Water temp is 24° – a touch warmer than usual for the season, so you can leave the thick rubber at home.
Tuesday afternoon, September 15th is the clear highlight. We’re looking at a 6ft swell from the SSW with a very long 17-second period – that’s proper groundswell pumping into the reef (3099 combined energy). Wind is glassy, completely calm from the SW. This is expert-only at that size, but for those with the bottle, it’s going to be absolutely pristine, powerful, and well-shaped.
Wednesday morning, September 16th pushes up to 8ft from the SSW, 15-second period, but the wind is onshore from the WSW at 10 km/h, so it’ll be a bit bumpy. The afternoon glass-off is the real deal though – same 8ft, glassy conditions, massive energy (2541). That one’s a beauty for the experienced crew only. Anything over 8ft is strictly for the big-wave hunters at this reef.
Then the swell backs right off. Thursday and Friday drop to small, short-period slop, with energy falling into the low hundreds. The weekend stays lean – glassy mornings but only 2-3ft of weak SW swell. A few fun ones Sunday with 4ft and glassy winds, but it’s not going to have any punch.
The next real standout kicks off Sunday, September 27th. Morning brings 7ft from the SSW at 17 seconds, glassy – enormous energy (2105). The afternoon jumps to 7ft from the SW, still glassy. That’s big, clean, dangerous surf for experts only. It stays solid through Monday morning at 6ft with calm winds, and Tuesday morning at 5ft with a 14-second period – still very clean. Energy readings are all in the four-digit range, so this is a sustained run of powerful, quality groundswell.
Crowds can be an issue when it’s good, so plan for a dawn patrol. This reef handles long-period SW swell like a charm – those big 15-17 second intervals will set up beautifully.
For the second week’s forecast, the 27th-29th September look like the prime target. Big, clean, and proper. Less certain at that range, but it’s looking like a solid bet.
Rusty.
