The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming down the pipe for Black Rocks Jetty.

We’ve got a solid run of surf ahead, but you’ve gotta be patient. The next couple of days are a write-off with poor, choppy conditions as a southerly wind messes things up. By Friday morning the 24th, things start to clean up nicely. The real standout is Monday the 27th—that’s the one to circle on the calendar.

Friday morning the 24th, we’re looking at a clean 4ft swell from the southwest with a 15-second period, and a light cross-offshore breeze. The water temp is sitting at a touch warmer than normal for this time of year, about 76°. Wave energy is moderate (865). It’s small but will be fun on a longboard.

Saturday the 25th is even better. Morning brings glassy conditions with a 4ft southwest swell (760 energy), and Saturday afternoon is glassy too with a 4ft swell from the south-southwest (678 energy). Clean, small, and super fun for cruising.

Sunday the 26th offers a tiny 3ft swell in the morning with a very long 20-second period and clean conditions. That long period means the waves will have real shape and power for their size—perfect for a point or reef setup like this spot. Energy is moderate (786).

Now, Monday the 27th is the main event. A solid 10ft southwest groundswell rolling in at 16 seconds. Energy is pumping at 3999, making for some serious wave power. It’s going to be glassy in the morning and clean in the afternoon. This is only for experienced surfers—that’s a lot of water moving. If you’re confident and keen, this is the session to aim for.

Tuesday the 28th stays excellent with 6ft to 8ft swell, glassy conditions, and very high energy (2894 to 2962). Again, for competent surfers only, especially as the size bumps up.

The rest of the week and into early August keeps delivering. Wednesday the 29th offers 5ft glassy surf (1226 energy), Thursday the 30th has 4ft to 6ft glassy conditions (1247 to 1381), and Friday the 31st morning is a standout with 7ft glassy surf (2342) before the wind shifts onshore in the afternoon.

Into the second week, we’ve got consistent swell but watch those wind changes. August 2nd morning looks good with 6ft glassy conditions and 2231 energy, then the wind goes offshore again on the morning of the 3rd with 6ft swell (1627). The 4th and 5th continue with clean, glassy mornings and solid 5ft to 5ft swell (around 1500 energy).

After that, it drops off. By August 6th, we’re left with small, weak, cross-shore junk. The run is over for a bit.

Crowds can be a factor here at times, so get on it early if you can.

Overall, the best bet is Monday the 27th for the big boys, and Saturday the 25th for a more mellow, clean session.

Rusty.
