Black Rocks Jetty Surf Forecast and Surf Report

Alright, let’s get into it. This is Rusty, and I’m looking at the 16-day window for Black Rocks Jetty.

We’ve got a solid run of surf coming up, but it starts off a little average before kicking into gear. The swell is mostly from the southwest, which is exactly what this spot loves. The water is sitting at 25°, a touch warmer than normal for this time of year, which is nice.

The first decent surf kicks off Saturday afternoon, September 5th. We’re looking at 5ft of SW swell with a 14-second period, giving the waves some real push. The wind is a light cross-off from the north, so the waves will be clean. The combined energy is moderate at 733. Not a standout, but a good warm-up.

Sunday, September 6th, is a beauty. Morning and afternoon both have 4ft of SW swell, 13-second period, and glassy conditions with a light west wind. The energy is in the moderate range (659 and 813). This is easy, clean, fun surf. A great day for a paddle.

Now, Monday September 7th gets a bit more size, but the wind turns cross-on from the south at 9 to 12 mph. The swell jumps to 7ft and 8ft, but it gets choppy. The energy is strong (1738 and 2420), but the quality fades. This is more for the experienced crew, and even then, it’s not the best.

The real standout is Tuesday afternoon, September 8th. The swell drops back to 10ft from the SSW, but with a 15-second period and a cross-off wind from the southeast. The combined energy is a massive 7507, indicating strong wave energy. This is an exceptional session for experts only. The waves will be powerful and clean. This is the one to circle.

Wednesday, September 9th, is equally impressive for the big-wave hunters. Morning and afternoon both have 12ft of SSW swell with a long 17-second period. The morning has a light offshore wind from the ENE, keeping it clean, and the afternoon goes glassy with no wind. The energy is very strong (7795 and 6041). This is heavy, powerful groundswell, best handled by the pros. The long period might make the waves a bit too lined up for a beach break, but at a reef setup like this, it’ll be world-class.

The swell drops through the rest of the week, but the conditions stay clean. Thursday September 10th has 6ft and 5ft of SW swell with glassy conditions, perfect for experienced surfers. Friday September 11th and Saturday September 12th have smaller, clean waves around 3ft to 4ft, good for a fun session.

Sunday September 13th sees the swell back up to 7ft in the afternoon with a 16-second period and glassy conditions. The energy is strong at 2193. Another excellent session for experienced surfers.

The following week, from Monday September 14th to Wednesday September 16th, offers a mix of solid swells and clean conditions. The standout in this second week is Tuesday morning, September 15th, with 8ft of SSW swell, 15-second period, and glassy conditions. The energy is 2391. That’s a very clean, powerful session for the experienced crew.

The surf starts to fade from Thursday September 17th, with smaller waves and poor conditions creeping in by Friday September 18th. The run ends with a few days of small, onshore wind, but the outlook picks up again on Saturday September 19th with a return to clean, glassy waves in the afternoon, and Sunday September 20th finishes the window with clean 5ft waves and a gentle offshore breeze.

Crowds are possible here, so keep an eye out.

The absolute best on offer? Tuesday afternoon September 8th and Wednesday September 9th. That’s the big, clean, powerful stuff for the experts.

Rusty.
