Black Rocks Jetty Surf Forecast and Surf Report

Alright, Rusty here, let’s have a look at what’s cooking.

We’ve got a solid run of surf coming up at Black Rocks Jetty. It’s not going to pump straight away, but there’s a really nice early window before things get a bit messy midweek, then a proper late-summer pulse to get excited about. The water is sitting at a lovely 25°, which is a touch warmer than normal for this time of year, so the first few sessions will feel real pleasant.

Sunday morning kicks it off with clean 4ft SW swell, period a nice and long 15 seconds – that’s proper groundswell energy. The wind is glass, absolute butter. We’re looking at moderate combined energy (618) and the reef will handle that direction beautifully. Sunday afternoon stays just as clean, same size, still glassy. This is a sweet little window to get the fins wet.

Monday and Tuesday morning hold similar 4ft SW swells, with clean conditions most of the time. Monday gets a light cross-on breeze so it’s not perfect, but Tuesday morning goes back to glassy again. The energy is still moderate (611-677). Decent, but not a standout.

Wednesday is another good one. Morning sees a 4ft SW swell with cross-off wind and clean faces. The period drops a touch to 14 seconds, still quality. Afternoon goes glassy again. This is consistent, reliable surf.

Thursday morning gets a bit onshore and messy – the swell drops to 4ft and the wind is straight on. Not one to get excited about. However, Thursday afternoon turns glassy again with 4ft, so a salvageable session for those with patience.

Now, Friday 14th August – this is where it starts to get interesting. The morning brings 6ft SW swell with a period of 13 seconds, and the wind is glass. Combined energy jumps to 1331 (strong). This is excellent for experienced surfers. The afternoon gets even better with 6ft SSW, still glassy, and the energy hits 1731. That’s proper power.

Saturday 15th August morning is a bit messy with a cross-on breeze, but the afternoon is an absolute stunner. 5ft S swell with a very long 17-second period, glassy conditions, and combined energy screaming 3223. That’s a lot of punch. This is a serious groundswell, and on a reef like Black Rocks, it’ll hold its shape beautifully. This is one of the true standouts of the whole forecast.

Then Sunday 16th August – the morning is the pick of the entire run. 8ft SSW swell, 16-second period, dead calm wind, and combined energy of 3506. That’s big, powerful, and clean. Experts only – this is well over the 8ft mark. The afternoon stays just as clean with 8ft and 2751 energy. If you’re skilled and hungry, this is your weekend.

From Monday 17th to Tuesday 18th, the swell eases back to 4ft, still glassy with good periods. Nice follow-up waves.

After that there’s a very quiet stretch from about Wednesday 19th through to Saturday 22nd. Swell drops below 3ft, periods are okay but the energy is weak (151-358). The wind stays clean on some days, so you might find a knee-high fun wave, but you’ll need a log and low expectations.

Then, hold onto your board – Sunday 23rd August. We get a massive 13ft SSW surge with a 16-second period. The morning is a bit unknown wind-wise, but the afternoon is glassy and combined energy is a wild 7926. This is exceptional, massive, and strictly for experts. It’s over a week away, so long-range, but the signs are there.

Monday 24th August drops back to 8ft, but the wind goes cross-on, so that big swell gets messy. Worth a look if you’re experienced and don’t mind some chop.

Bottom line: the best windows are Sunday 9th for a clean start, Saturday 15th afternoon for a big clean groundswell, and Sunday 16th morning for expert-level perfection. The big pulse on the 23rd is one to watch closely.

Rusty.
