Black Rocks Jetty Surf Forecast and Surf Report

Alright, surfers, Rusty here. We’ve got a solid run of surf on the way, so let’s get into it.

First up, we’re looking at Black Rocks Jetty. This exposed reef setup is a magnet for SW groundswell. The water temp is about average for this time of year, nothing unusual. The good news is that we’ve got a solid, long-period SW groundswell that’s going to be running for days. It’s a powerful swell, but because it’s coming from the southwest, it’s hitting the jetty perfectly. The combined energy is strong, clocking in at (2777).

Tuesday morning, July 28, is a standout. You’ve got a 7ft SW swell with a 15-second period, and the wind is glassy from the NNE at 3 mph. The conditions are excellent for experienced surfers. This is the pick of the week. The afternoon switches to a slight SSW wind, but still glassy, with a 17-second period and the energy climbing to (2831). That’s a very long, powerful groundswell.

Wednesday, July 29, keeps the quality high. Morning is glassy from the NW with a 7ft SSW swell, 14-second period, and energy at (1676). The afternoon holds a 6ft SSW swell, still glassy, with energy at (1222). This is all top-tier, clean stuff.

Thursday, July 30, the swell drops a touch but the quality remains. Morning has a 5ft SSW swell, 13-second period, and glassy SW wind. The afternoon gets a bit of a boost with a 6ft and 16-second period, and it’s dead calm, glassy. Energy at (1373). This is a beautiful day.

Friday, July 31, the swell holds at 6ft, 16-second period, and the wind is cross-off from the NNW. It’s clean, but not quite glassy. Still very good.

Saturday, August 1, is another top day. Morning is a 6ft SSW swell, 15-second period, with glassy W wind. Afternoon has a 6ft SSW swell, 14-second period, and it’s dead calm. Energy at (1525). Beautiful.

Sunday, August 2, the morning is perfect with a 5ft SSW swell, 15-second period, and dead calm. The afternoon gets a bit bumpy with a 6 mph onshore SW wind and a 6ft, 17-second swell, but it’s listed as marginal. The morning is the better session.

From Monday, August 3, into the second week, the swell drops. We’re looking at 4ft to 3ft SSW swells. The wind is mostly glassy, so there will be fun, clean waves on offer, but nothing like the first week. The energy drops to the hundreds.

Then, a real standout reappears. Monday, August 10, is a second major highlight. The morning delivers a 7ft SW swell, 16-second period, with glassy W wind. Energy is a solid (2767). The afternoon is a 7ft SW swell, 16-second period, with a clean cross-off wind from the N. This is excellent, powerful surf for experienced surfers.

Tuesday, August 11, is a mixed bag. The morning has a big 10ft swell from the SSE, but a short 10-second period and a cross-wind. That’s a lot of energy (3369), but the quality is a bit jumbled. The afternoon is much better, with a 7ft S swell, 13-second period, and glassy conditions. This is a solid session.

The last day of the forecast, Wednesday, August 12, the swell drops to 6ft with a 12-second period, but an onshore SW wind makes it marginal.

So, to sum it up: the first week is a feast of glassy, long-period SW groundswell. The absolute best sessions are Tuesday morning, July 28, and Monday morning, August 10. After that, it’s much smaller but still clean. The crowds are listed as "sometimes" at Black Rocks, so you might have company, but the quality will be worth it.

Rusty.
