Black Rocks Jetty Surf Forecast and Surf Report

Hey folks, Rusty here. Let’s talk about the next couple of weeks at Black Rocks Jetty. It’s a reef break, and it’s exposed to the SW swell. The water’s sitting at 77° and that’s a touch warmer than usual for this time of year.

We’ve got a solid run of clean, glassy surf kicking off Friday afternoon, August 7th. The swell is a small 1 ft from the SSW with a crazy long 22-second period – that’s proper groundswell. The energy is moderate (421). It’ll be tiny but perfectly clean with glassy conditions. This stretch is where it’s at for a patient surfer on a log.

Saturday morning, August 8th, sees the swell bump up to 4 ft from the SW, period still long at 18 seconds. The combined energy is climbing (779). Saturday afternoon gets a little more size at 4 ft, same direction, 16-second period (978). Sunday, August 9th, keeps the good times rolling with 4 ft SW swell at 15 seconds (619). The wind stays glassy right through this whole first run. Conditions are very good, and crowds can be an issue here sometimes, so get out early.

By Monday, August 10th, we’ve got consistent 4 ft SW swell at 14-16 seconds, still glassy. The energy is moderate to strong (677-923). This is a fantastic block of days. The highlight of this first week is probably the run from Saturday to Monday – clean, waist-to-chest high glass.

Things get a little more interesting for the experienced crew. On Friday morning, August 14th, we see the swell hit 5 ft from the SW, 13-second period, with the energy jumping to 1145. It’s still glassy. It gets bigger on Saturday, August 15th, with a 7 ft SSW swell at 18 seconds (3972 energy), but the 9 mph SSE cross wind makes the surface a bit bumpy. The real standout for the bigger stuff comes on Sunday morning, August 16th. We’ve got a clean 8 ft SSW swell with a 16-second period, glassy wind, and very strong energy (2853). This is excellent, expert-level surf. The period is long enough to hold shape, but at that size and with that direction, it’ll be a challenge. The following Monday morning, August 17th, also looks excellent with a 5 ft S swell at 18 seconds, completely calm conditions (1855 energy). That’s a proper session for the experienced surfer.

After that run, the swell starts to back off. From Tuesday August 18th through the end of the forecast window, expect smaller, cleaner waves. Mornings are mostly glassy with swell around 2 ft to 3 ft from the SW. The energy settles back to moderate (300-574). It’s good, clean, small-wave fodder for a mid-length or a longboard. The consistency is good, so there’ll be waves to be had. The period stays around 13-15 seconds, so the quality remains decent even as the size drops.

If you’re after clean, manageable surf that’s not going to smash you, jump on that first weekend. If you’ve got the skills and the courage, August 16th and 17th are the ones to circle on the calendar – they’re the real standouts of this outlook.

Stay safe out there.
