Alright, Rusty here, let's talk about what's coming up at Black Rocks Jetty. This spot is a solid reef break, and it's on the menu for a good run of swell. The water temp is feeling about average for this time of year, nothing wild to report there.

We're kicking off Saturday, July 11th, with a nice pulse. The morning is glassy, and we've got a 6ft SSW groundswell rolling in with a long 15-second period. The combined energy is cooking at 1236 (moderate to strong), and it's clean. This is proper advanced territory though, over 5ft, so leave the beginners on the beach. The afternoon holds similar, 6ft and still glassy, with energy up to 1361. This is where it's at.

Sunday, July 12th, the swell builds. Morning is glassy again, 8ft of SSW groundswell at 15 seconds, and the energy is pumping at 2699. That's solid, powerful stuff, but with the size over 8ft, this is strictly for the experts. By afternoon, the wind swings cross-shore and drops the quality a notch, so make the most of the morning.

Monday, July 13th, brings more of the same goodness. Both the morning and afternoon sessions are glassy with 7ft and 7ft SSW swells, period hanging around 14 seconds. Energy is strong at 1876 and 1598. These are excellent, clean conditions for experienced surfers.

Tuesday, July 14th, starts glassy again, 6ft SSW swell, energy at 1093. Afternoon goes dead calm, glassy as it gets, with a smaller 5ft SSW swell at 796 energy. It's very good, clean surf, but the size is dropping.

Now, from Wednesday, July 15th, things get quieter. The swell backs off to around 4ft and smaller, and the wind is mostly cross or cross-on. The energy drops into the hundreds. There'll be some surfable waves, but nothing to get excited about for the rest of that week. The second week, from July 20th onwards, sees a big spike in swell again—up to 8ft and even 10ft on the 22nd—but the wind is strong and cross-on, making it choppy and messy. That setup looks more interesting for kite surfing than paddle surfing. There's a promising blip on the weekend of July 25th and 26th, with another pulse of SSW groundswell and a very long period sneaking in. The morning of Sunday, July 26th, has a glassy 5ft SW swell with a massive 23-second period, and energy is through the roof at 4226. That's a standout, but it's long-range, so keep an eye on it. That long period will hold up best right here at the reef.

So the pick of the window is the first weekend and Monday: Saturday the 11th through Monday the 13th. Clean, glassy, punchy groundswell for those who can handle it. Crowds are "sometimes" an issue here, so you might have company, but the quality will be worth it.

Rusty.
