Black Rocks Jetty Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get stuck into this one.

The next couple of weeks are looking pretty special for Black Rocks Jetty, with a long run of clean, glassy conditions and a solid south-west swell building through the period. The water is sitting at 77°F which is a touch warmer than normal for this time of year – nice.

We kick off Wednesday morning, August 5th, with a clean 2ft south-west swell, period of 15 seconds, and glassy conditions. It’s small but the energy is already there (298). By Wednesday afternoon, it’s up to 3ft, still glassy, and the swell direction is south-west. This is a sweet little warm-up.

Thursday, August 6th, the morning stays glassy with 3ft south-west swell, period 13 seconds – clean and fun. The afternoon turns a bit cross-onshore, so make the most of the early session.

Friday, August 7th, is another morning glass-off with 3ft south-west swell. The afternoon sees a spike in period to 22 seconds from the south-south-west, but the swell drops to 1ft – very long period, very clean, but tiny. Worth a look if you’ve got a log.

Now, Saturday, August 8th, is where things start to get exciting. The morning is dead calm, 4ft south-west swell, 18 seconds of gorgeous groundswell, and the energy jumps to 779. Glassy, clean, and punchy. The afternoon holds 4ft with a 16-second period, still glassy. This is a standout morning.

Sunday, August 9th, the morning is flat calm again, 4ft south-west swell, 15 seconds – beautiful. The afternoon gets a bit messy with a cross-onshore wind, so surf early.

Monday, August 10th, is a bit of a mixed bag – the swell size holds at 4ft but the wind is cross or onshore, so the quality drops. Not the day to chase.

Tuesday, August 11th, we’re back in the game. Morning glass, 4ft south-west swell, 15 seconds, and energy building to 723. The afternoon stays glassy with 4ft – a solid day.

Wednesday, August 12th, is the real standout. The morning is dead calm, 6ft south-west swell, 14 seconds, and the energy jumps to 1196. That’s moderate-to-strong energy, and the conditions are absolutely glassy. This is a top-tier day for experienced surfers – the size is pushing into intermediate territory, but the quality is unreal. The afternoon turns a little cross-onshore, so nail the morning.

Thursday, August 13th, the morning is glassy again with 5ft south-west swell, 13 seconds, energy over 1000. The afternoon sees the swell jump to 7ft with the same period, and energy hits 1704. This is big, powerful, and clean. For experts only – the 7ft is well into the “big” range, and the 13-second period gives it plenty of punch.

Friday, August 14th, the swell maxes out at 8ft in the morning, 12-second period, but the wind is cross-onshore, so it’s going to be a bumpy, powerful beast. The afternoon stays onshore. This is more of a kite-surfing setup than a paddle-friendly one.

Saturday, August 15th, the swell drops to 5ft but the period stretches to 18 seconds – very long, very clean if the wind plays ball. The morning is cross-onshore though, so it’s a bit tricky.

Sunday, August 16th, is another standout. Morning glass, 7ft south-south-west swell, 17 seconds, and energy of 2653 – that’s strong to very strong wave energy. The afternoon is dead calm, glassy, with the same 7ft swell. This is big, clean, and powerful. Experts only – the size and period will make for heavy, heaving waves at the reef. If you’ve got the nerve, this is the session.

The following week eases off. Monday, August 17th, the wind is onshore with 4ft swell, so it’s messy. Tuesday, August 18th, sees a drop to 3ft south swell, but the morning is dead calm and glassy – a nice little recovery session. Wednesday, August 19th, is even smaller at 2ft south-south-west, but glassy all day. Thursday, August 20th, finishes the run with a glassy morning, 4ft south-west swell, building to 4ft in the afternoon, still glassy.

Overall, the best on offer is Wednesday, August 12th, for the clean, moderate-to-strong energy and glassy conditions, and Sunday, August 16th, for the big, powerful, clean groundswell. The first week is the real gold here.

Rusty.
