Black Rocks Jetty Surf Forecast and Surf Report

Alright, Rusty here. Let's break down what Black Rocks Jetty has cooking. This reef break is a very consistent, exposed spot that really needs a solid SW groundswell to work, and it's about to get a good one. The water is sitting at about 76°, which is a touch warmer than usual for this time of year, so that's a nice bonus.

The first decent surf we'll see kicks off Sunday, September 6th, but it's not the main event. It's a bit marginal with cross-onshore wind, so keep your expectations low. Monday the 7th sees the swell building quickly, hitting 7ft to 8ft from the SSW, but with a strong S cross-onshore, it's going to be choppy and messy. That one's a pass.

Now, Tuesday the 8th afternoon is where things get interesting. The swell jumps to a solid 12ft from the SSW, and the combined energy is pumping hard (7928). It's a cross-shore breeze, but the size is getting into expert territory.

But the absolute standout, the one you've been waiting for, is Wednesday the 9th. Morning and afternoon both serve up 12ft SSW groundswell with a very long 17-second period. And here's the kicker: the wind goes glassy, dead calm. The combined energy is massive (8087 in the morning). This is exceptional, world-class reef surfing, but only for experienced crew. That size and power on a reef isn't messing around. If you're an expert, this is your window.

Thursday the 10th is still a good call, especially the afternoon with 5ft and glassy conditions, but the energy is dropping. The rest of the week sees the swell ease back. Friday the 11th through Saturday the 12th offer some clean, glassy mornings with waist-to-chest high waves, but nothing to write home about.

There's a gap of smaller, less exciting surf through the middle of the second week. Then, around Tuesday the 15th, the SSW swell bumps back up to 7ft with a 16-second period and offshore NE wind in the morning, making for some clean, powerful waves for experienced surfers again. Another nice, glassy window appears on Wednesday the 16th afternoon with a 7ft S swell and zero wind, but it's a bit of a drop from the peak.

Towards the end of the run, from the 17th onward, we're back to smaller, clean, but much weaker surf. A few glassy mornings with 3ft to 4ft waves are okay for a longboard on the right tide, but nothing to get fired up about.

In a nutshell: the clear standout is Wednesday the 9th. Massive, glassy, and powerful. Tuesday the 15th morning is a distant second for the second week, but that Wednesday is the real deal. Don't sleep on it.

Rusty.
