Black Rocks Jetty Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into it.

We’ve got a solid run of surf on the cards at Black Rocks Jetty, starting right now. This is a reef break that is very consistent, so it’s a reliable bet for the advanced crew. The water is sitting at a touch warmer than normal for this time of year, 77°, so you’ll be comfortable in a spring suit. The swell direction is a persistent SSW, which is a good match for the spot’s optimum from the southwest.

The action kicks off on Tuesday morning, July 28th. It’s a beauty: 7ft SSW swell with a very long period of 15 seconds, and the wind is glassy from the NNE. This is a proper groundswell, so there’s a lot of energy in the water (2777). That long period will make for some cracking lines on the reef, but the sets will be spaced out. It’s an excellent session for experienced surfers. The afternoon holds the same size, 7ft, with a slightly longer 17-second period out of the SSW, and the wind drops to a dead calm. The energy is even higher (2831). It’s a top-tier day.

Wednesday, July 29th, keeps the quality high. The morning is glassy with a 7ft SSW swell, 14-second period, and strong energy (1676). The afternoon settles a touch to 6ft, but still glassy, with a slight air from the west. It’s still excellent.

Thursday, July 30th, the swell drops a bit. The morning is 5ft, glassy, but the period is still a solid 13 seconds. The afternoon picks up to 6ft, clean with a light SW wind, and the period bumps back up to 16 seconds (1611 energy). That’s a strong candidate for the afternoon session.

Friday, July 31st, is a ripper. 6ft SW swell, glassy in the morning, and the period is 16 seconds. The afternoon is the same size, with a few clouds but still glassy. Excellent conditions.

The standout of the first week is Saturday, August 1st. The morning is a dead calm, 6ft SSW swell with a 15-second period and 1447 energy. It’s a bluebird day. The afternoon has a few rain showers but it’s still glassy. Sunday, August 2nd, the morning is clean with 5ft, but the afternoon gets a cross-onshore wind, so it’s a bit more marginal.

Monday, August 3rd, sees a drop in swell to 4ft, but it’s glassy. That trend continues into Tuesday, where it’s down to 3ft and still clean. The energy drops to 421, so it’s getting weak. The afternoon turns ugly with a cross-onshore wind and rain.

We get a spike back on Wednesday, August 5th. The morning has a 5ft SSW swell, 16-second period, and a cross-offshore wind, making it clean. The energy is back up to 1198. The afternoon gets messy with a cross-onshore wind, so get it in the morning. Thursday, August 6th, is back to clean lines with 4ft and glassy conditions.

Now, the real standout. Mark your calendars for Monday, August 10th. This is the best on offer in the entire 16-day window. The morning is a dead calm, 8ft SSW swell with a 16-second period and a massive 3672 combined energy. The afternoon is the same size, 8ft, with 4091 energy. That is a serious, powerful, long-period groundswell. It’s expert territory only at that size, and the long period means it’ll be a bit walled up at the beach, but on this reef? It’s going to be a freight train. The confidence is high on this one, but it’s 13 days out, so keep an eye on it.

After that, the swell backs off. Tuesday, August 11th, is 6ft and glassy, and Wednesday, August 12th, brings a beautiful 6ft SW swell with a 19-second period (2590 energy) in the morning, and a 7ft, 18-second period in the afternoon. That’s a very long period, so the sets will be fat and walled, but the reef will handle it.

So, overall, there’s no gap in the good surf. It’s a solid run. The two standouts are the calm, glassy 7ft on the 28th and the big, powerful 8ft on the 10th of August. Get out there.

Rusty.
