Black Rocks Jetty Surf Forecast and Surf Report

Alright, Rusty here, let’s talk about what’s on offer.

We’ve got a solid window of swell coming up for Black Rocks Jetty, a very consistent reef break that’s exposed to the SW. The water is sitting at 75.9°, which is pretty much spot on for this time of year, so no surprises there.

The action starts on Tuesday 14th July with glassy conditions and a 4.9ft SSW swell pushing in with a solid 13-second period. The combined energy is moderate (750). It’s clean, it’s got push, and it’s the start of a good run. Wednesday 15th July morning is even better: 4.3ft of SSW groundswell, glassy, and the energy is building (862). That’s a real sweet spot for a reef break like this – long period, clean lines, and easy paddling between sets.

Thursday 16th July sees the swell dropping to 2.3ft with a shorter 10-second period, but the wind goes offshore in the morning, so it’s still ridable and clean for a small-wave session. Not a standout, but a fun little window.

Then Friday 17th July brings a spike in period – 17 seconds on the morning of the 17th with 2.3ft of S swell, but it’s cross-offshore. The energy is light (331) and the long period will make it a bit straight at the reef, but a log or a longboard could still work.

The first real standout comes on Monday 20th July. The swell jumps to 6.2ft SW with a 15-second period, and the energy is strong (1641). The wind is cross-onshore, so it’s a bit textured, but for a reef break that handles size, it’s still got plenty of grunt. The size builds Tuesday and Wednesday, but the wind stays cross-onshore, so it’s more for the experienced crew who don’t mind a bit of chop.

Thursday 23rd July gives us a little reset: glassy, 3.0ft SW at 13 seconds, and clean. Nice for a morning paddle.

Now, here’s the big one. Friday 24th July morning is absolute magic. 7.5ft of SW groundswell with a 17-second period, glassy, and the combined energy is massive (3488). That’s a serious groundswell hitting a reef with no wind. For experts only – this is well over 8ft on the sets, and it’s going to be powerful. This is the best of the whole run.

Saturday 25th July stays big, but the wind swings cross-onshore, so it’s less clean. Still, 7.2ft to 7.9ft SSW with long period is a lot of ocean moving.

Sunday 26th July morning is another glassy peak: 8.2ft SW at 15 seconds, energy at 3178. Again, experts only, but absolutely pristine conditions if you’ve got the nerve.

Monday 27th July is the final crown. Glassy, 8.2ft SW with a 19-second period – that’s about as long as it gets. The energy is 3782. It’s a perfect, powerful groundswell on a reef. This is the absolute standout window for experienced surfers. The winds are calm all day, so both morning and afternoon sessions are on.

After that, the swell slowly backs off through the 28th and 29th, with cleaner conditions returning on the 29th morning with 4.9ft SW at 15 seconds and glassy wind. A nice way to wrap it up.

So, if you’re advanced, mark your calendar for Friday 24th July morning, Sunday 26th July morning, and Monday 27th July all day. That’s the cream of the crop. For everyone else, the first few days (14th-15th) are clean and moderate – perfect for getting out there.
