Black Rocks Jetty Surf Forecast and Surf Report

Right, pull up a seat, grab a coffee. Rusty here. Let’s have a look at what’s coming for Black Rocks Jetty.

First thing you’ll notice is the water temp. It’s sitting at 76°, which is a touch warmer than normal for this time of year. Not a big deal, but you can feel that little bit of extra warmth in the water.

The next few days are a bit of a mixed bag, but we’ve got a standout window that’s worth circling. Sunday (the 6th) is nothing to write home about – small, 4ft swell from the SW, and the wind is blowing straight onshore. It’s marginal. The combined energy is weak (659), and the tide is likely messing things up. Monday (the 7th) builds a bit more size, hitting 7ft to 8ft from the SSW, but the wind swings cross-onshore and gets choppy. The energy jumps up (1738 to 2419), but the quality is just not there for a good paddle.

Tuesday (the 8th) is where it starts to get interesting. The swell is still solid, 7ft to 10ft from the SSW, with a long period of 15 to 16 seconds. That’s a proper groundswell. The wind goes light cross-shore, so the surface is just rippled. The energy is building strong (4113 to 7081). For experienced surfers, the afternoon looks promising, but it’s still a bit on the borderline.

Wednesday the 9th is the real standout. This is the one to aim for. We’ve got an 12ft SW groundswell, and the period is a massive 17 seconds – that’s about as clean and powerful as it gets. But the real kicker? Glassy conditions. Zero wind in the morning, and dead calm in the afternoon. The combined energy is pumping (7705 in the morning). This is exceptional surf, but make no mistake, at 12ft and that power, it’s for experts only. The long period means it’ll be holding up well on this reef, but the sets will be more spaced out, making the paddle out a bit easier if you’re fit. The shape should be solid.

From Thursday (the 10th) through to the end of the first week, the swell drops back to a more manageable 3ft to 6ft, still with good SW direction and glassy or light offshore winds. The energy is moderate (533 to 2063). It’s clean, fun surf for experienced surfers, but nothing that will blow your mind compared to that Wednesday.

The second week is a bit more of a waiting game. Swell stays around 3ft to 5ft, with periods dropping a bit. From Sunday the 13th to Tuesday the 15th, we get some nice glassy mornings with 4ft to 7ft SSW swell and good energy (1023 to 1961). It’s good, clean, but not the same power. The afternoon of the 15th and the 16th sees the wind turn cross-onshore, dropping the quality. The 17th and 18th get small again, 2ft to 3ft, with weak energy. The 19th picks up a bit with a 4ft SW swell and glassy conditions, which is a nice little window. The 20th and 21st have some clean moments, but the swell is small and the energy is low (456 to 580).

So, the pick of the lot is Wednesday the 9th at Black Rocks Jetty. If you are an expert, that’s the day. The rest of the window is a solid run of clean, fun waves for the experienced crew, but don’t expect the same power.

Rusty.
