The Lowdown
Alright, surfers, Rusty here with a look at what's on the menu. We've got one spot to focus on: Black Rocks Jetty. This is a solid, very consistent reef break that's exposed to the SW, so it knows how to handle a decent south swell. The water's sitting at a toasty 76°F, which is a touch warmer than normal for this time of year, so you might get away with just a springsuit.
Right now, we're in a bit of a waiting game. The first real action kicks off on Sunday, September 6th. It's not the best, with a 4ft SW swell and a light onshore wind making things a bit messy. The wave energy is weak (813), so don't expect much.
But hold on, because things start to get interesting from Tuesday, September 8th. The swell builds to 10ft from the SSW with a 15-second period. That's a lot of energy (7650) and the wind turns light and cross-shore, cleaning things up. This is advanced territory, and it's only for the experienced crew.
The real standout, the one you've been waiting for, is Wednesday, September 9th. We've got a solid 12ft SSW swell with a very long 17-second period – that's groundswell gold. The wind goes glassy in the morning with a light breeze. This is exceptional, top-tier surf for experts. The wave energy is massive (8087). Just remember, with a period that long, it might be a bit straight at a beach break, but Black Rocks being a reef should handle it beautifully. Expect some serious sets and clean faces.
After that peak, the swell eases but stays fun. Thursday, September 10th, still has clean 7ft SSW swell with glassy conditions, excellent for experienced surfers. Friday, September 11th, the swell drops to 3ft from the S, but with flat calm winds, it'll be a good day for a smaller crew on logs or mid-lengths.
The second week looks more relaxed. We've got some clean windows, like Saturday, September 12th afternoon with a glassy 4ft SSW swell, and Sunday, September 13th morning with a 5ft SW swell and a very long 18-second period, offering clean waves for experienced surfers. The energy drops off, but there are still fun, clean waves to be had through to the end of the forecast, with small but glassy conditions on the 20th and 21st.
So, to wrap it up: if you're an expert and you want the best, circle Wednesday, September 9th on your calendar. The conditions are about as good as it gets. For everyone else, the following days offer plenty of clean, smaller surf.
Rusty, signing off.
