Black Rocks Jetty Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s coming down the pipe for the next couple of weeks.

We’ve got a serious slab of Southern Ocean energy lining up, and it’s all pointing at one spot: Black Rocks Jetty. This is a reef break, exposed to the southwest, and it’s very consistent. The water is sitting at 76°, which is a touch warmer than usual for this time of year.

The standout is clear as day. Wednesday morning, September 9th. We’re looking at a massive 12 ft swell from the SSW, with a very long period of 17 seconds. The energy is off the charts (8315) and the wind is absolutely glassy. This is pure, heavy groundswell—only for experts. The water temp anomaly is only a degree or so above normal, but the power here is the story. If you’re an experienced surfer, this is the session to circle. The afternoon will hold decent size at 12 ft, but the energy drops a notch (6300), though it stays glassy.

Thursday, September 10th brings a step down in size but still solid. The morning has 7 ft SSW swell at 14 seconds, and the wind is glassy. A good option for strong intermediates who missed the big Wednesday. The afternoon drops to 5 ft, still clean.

From Friday, September 11th through Saturday, September 12th, the swell backs off to 4 ft to 5 ft. The wind stays clean, making for fun, user-friendly waves. The energy is moderate (541 to 885), so it’s not pumping, but it’s a nice window for smaller boards.

Sunday, September 13th is another highlight. The morning kicks off with a glassy 5 ft SSW swell, but the period jumps back to 17 seconds, and the energy is strong (1659). The afternoon holds at 6 ft with 16 seconds. This is excellent, clean surf for experienced surfers.

A heads up: Monday, September 14th and Tuesday, September 15th get a bit messy. Monday morning has a cross-on wind, and by Tuesday morning, a moderate breeze from the SSE is making things choppy. The quality drops. Tuesday afternoon, however, cleans up nicely with a cross-off breeze and a 6 ft SSW swell, 17 seconds, and strong energy (2213).

Wednesday, September 16th sees a jump in size again to 8 ft, but the wind is onshore, making it a bit of a mixed bag. It’s still big, but only for the very keen.

The following week, from Thursday, September 17th onwards, the swell drops. We get a few fun days around Friday, September 18th with a 4 ft SW swell and a very long 20-second period, glassy conditions. Then Saturday, September 19th and Sunday, September 20th offer clean, offshore winds with 4 ft to 4 ft SW swell. Good options for a relaxed session.

The very end of the run, September 22nd and 23rd, looks like a write-off with strong onshore winds and rain. The run finishes on Thursday, September 24th with a glassy morning and 5 ft SW swell.

So, the big winner is Wednesday morning, September 9th. If you’re an expert, don’t miss it. The second best is Sunday, September 13th for its clean, powerful conditions. Everything else is just fun, clean surf for the quiver.

Stay safe out there.
