Black Rocks Jetty Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s coming our way.

We’ve got a solid run of surf ahead, starting this Thursday afternoon and running for a good couple of weeks. The main event is a long, strong SSW groundswell that’s going to stack up nicely, and the winds are playing ball for most of it. The water is sitting at 77°, which is a touch warmer than normal for this time of year – a nice little bonus.

The standout spot is Black Rocks Jetty. It’s a very consistent, exposed reef break that handles this SW swell direction perfectly. This first pulse is a beauty. Thursday afternoon we’re looking at a clean 6ft SSW swell, with a period of 16 seconds. That’s proper, long-period groundswell, and with glassy conditions and light winds, it’s going to be excellent for experienced surfers. The combined energy reading is 1373 (moderate to strong), so there’s some real grunt behind it. This wave is for advanced crew only at this size.

Friday keeps the same 6ft SSW swell running, with a 16-second period in the morning and 15 in the afternoon. Morning winds are a light cross-off, and the afternoon goes glassy again. Another top day for those who know the reef.

Saturday the 1st of August is probably the pick of the bunch. The swell bumps up to 6ft from the SSW, with a 15-second period, and we’ve got glassy conditions all day. The combined energy jumps to 1447 (moderate to strong). This is about as good as it gets for this break – clean, powerful, and consistent. Expect a crowd though; this spot is popular for good reason.

Sunday the 2nd drops off a little to 4ft, still a clean 15-second SSW swell in the morning. The afternoon picks up to 5ft but the wind swings onshore, making it more marginal. Still, the morning session is a glassy winner.

Monday the 3rd through to Wednesday the 6th sees the swell taper down to the 2ft to 4ft range, with periods staying in the 13 to 15-second zone. The winds are mostly glassy, so the waves will be clean and fun, but it’s definitely smaller. Energy readings drop to the 200-500 range (weak to moderate), so it’s more of a longboard or fish kind of wave.

Thursday the 7th is a bit of a write-off with a tiny 2ft swell, but it picks up again on Friday the 8th. That Saturday the 8th and Sunday the 9th are looking like another strong pulse. Saturday afternoon has a 4ft SW swell with a 16-second period and glassy conditions – energy back up to 1031 (moderate). Sunday morning the 9th is even better with a 4ft, 15-second SW swell, calm winds, and a combined energy of 1062 (moderate). That’s a top-tier morning.

Monday the 10th holds a solid 5ft SW swell with a 15-second period and glassy conditions – another excellent session for the experienced crew. After that, the window starts to close. Tuesday the 11th gets a bit messy with cross-onshore winds and choppy conditions, and by Wednesday the 12th we’re back to smaller, cleaner waves in the 3ft to 3ft range. The last few days, from the 13th to the 14th, are just small, ordinary surf as the swell runs out of steam.

If you’re a beginner, keep an eye on the smaller days around the 3rd to 6th and again on the 12th, but stay away from anything over 5ft – that’s expert territory here.

So, to sum it up: the best windows are Thursday the 30th of July through Saturday the 1st of August, and then the weekend of the 9th and 10th of August. Get out there.

Rusty.
