Black Rocks Jetty Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s coming down the pipe for Black Rocks Jetty. It’s a bit of a slow start, but once this southern ocean gets cranking, it’s going to be a wild ride for the crew that knows what they’re doing.

We’re looking at a pretty quiet few days to kick things off. Friday the 17th and Saturday the 18th are a write-off, honestly. The swell is small and the wind is a messy cross-onshore, making for poor conditions. You’d be better off waxing your board at home. There’s a bit of a gap here until we see something worthwhile.

The first real glimmer of hope comes Sunday morning, the 19th. The wind goes glassy, and we’ve got a clean 3ft swell rolling in from the SW. It’s small, but it’s clean. The combined energy is moderate (496), and with that glassy surface, it’ll be a fun session for a longboard or a fish. The water temp is sitting at 76°, which is about average for this time of year, so no surprises there.

Then, Monday the 20th is where it starts to get interesting. The swell jumps up to 7ft in the morning and 8ft in the afternoon from the SSW, with a solid 13-14 second period. The energy is strong (1753-1859), and it’s glassy. This is where the reef comes into play. That’s a proper groundswell. For a reef break like this, that long period means the waves will have real shape and power, but it’s getting into expert territory. Beginners, stay on the beach.

Tuesday the 21st is still solid first thing, with 5ft and clean cross-offshore winds, but the afternoon turns into a bit of a mess with a cross-on breeze. The surf quality drops off after that until the end of the week.

Now, look ahead. The real standout is Sunday the 26th afternoon. We’ve got a 3ft swell, but the period is a massive 20 seconds. That’s a very long period groundswell. The combined energy is strong (1072). For a reef, this is a dream. Those waves will be lined up, with plenty of time between sets to paddle out. It’s glassy, too. This is a gem.

But the absolute king of this forecast is Wednesday the 29th. The morning session is hitting a solid 12ft from the SSW, with a period of 18 seconds. The combined energy is a massive 7068. That is exceptional, powerful surf. The wind is glassy. This is for experts only. If you’re not comfortable in big, heavy reef waves, this is a serious spectator sport. The afternoon gets a bit onshore, so the morning is the window.

The first of August sees another big pulse, with 12ft and glassy conditions, but it’s the same story: big, powerful, and for the experienced crew only.

So, to sum it up: the first few days are a wash. The best on offer for the average surfer is that Sunday the 26th afternoon session. But for the big-wave chargers, circle Wednesday the 29th morning. It’s a long way out, so don’t lock it in, but it looks like a proper event.

Stay safe out there.
