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 coming up at Black Rocks Jetty, so clear your schedule. The water’s sitting at 77°, which is a touch warmer than normal for this time of year – nothing crazy, but you’ll notice it’s nice and comfortable.

The first real action kicks off on Thursday afternoon, July 9th. It’s small but clean with a 3ft S swell and glassy conditions. Not a standout, but the long period (10 seconds) gives it a bit of shape on the reef. Friday, July 10th, is where it starts to get interesting. Glassy conditions all day with a 3ft SW groundswell, and the period jumps to 15 seconds. The energy is building (388 in the morning, 582 by the afternoon) and the wind is nil. For a reef setup, this is a dream start.

Now, the real standout is Saturday, July 11th. This is the best of the week. You’re looking at a 5ft to 6ft SW groundswell, period locked in at 15 seconds, and glassy conditions all day. The combined energy is massive (1117 morning, 1361 afternoon). This is not for beginners – it’s over 5ft, so it’s expert territory. The wind is light offshore or glass, so the waves will be clean and lined up. For a reef, this long period will produce some proper, powerful walls. This is the call.

Sunday, July 12th, is a write-off. The swell jumps to 8ft, but the wind swings onshore from the SSE at 12 mph, turning it into a messy, cross-shore chop. It’s big, but not worth it for paddle surfing. Honestly, this setup looks more interesting for kite surfing.

We get back into it on Monday, July 13th. The swell drops to 7ft, still a solid SSW groundswell, and the wind goes glassy or light cross-offshore. The energy is still strong (1734). It’s clean again, but still only for the experienced crew. Tuesday, July 14th, is similar but smaller at 5ft, with glassy conditions and a solid 13-second period. Very good, clean surf.

There’s a brief drop on Wednesday and Thursday, July 15th and 16th, with swell dropping to 2ft – 4ft. It’s surfable, but ordinary. Friday, July 17th, brings a nice surprise: a clean 3ft S swell with 15-second period and glassy conditions by the afternoon. Good quality for a small day.

The second week holds some promising stuff. Saturday, July 18th, is small. But Sunday, July 19th, is a standout for the second week. The morning is glassy with a 3ft SW swell, but the afternoon turns on: 4ft SSW swell with a massive 18-second period, glassy conditions, and energy at 1261. This is a very long period groundswell – on a reef, it’ll be super clean, though the sets will be few and far between. It’s excellent, but you’ll want to be patient.

Monday, July 20th, is another big one with 6ft SSW swell and 15-second period, glassy in the morning. That’s a powerful, expert-only wave. The afternoon turns onshore, so get it in the morning.

The rest of the week holds good, clean swell in the 4ft to 5ft range, with long periods and mostly glassy or clean conditions. The last big highlight is Friday, July 24th: 5ft SSW groundswell, 15-second period, glassy, and energy over 1000. A proper way to end the run.

The main thing at Black Rocks Jetty is consistency – it’s very consistent, so even the smaller days have something to offer. Saturday the 11th is the absolute standout, and Sunday the 19th is a promising long-range call. No crowds mentioned, but it can get busy, so get there early.

Rusty.
