Black Rocks Jetty Surf Forecast and Surf Report

G’day, Rusty here. We’ve got a solid 16-day window ahead of us at Black Rocks Jetty, and I’m telling ya, there’s some real gems in this run. The water is sittin’ at 75.7°, which is a touch warmer than normal for this time of year – you’ll feel it, trust me.

This reef break is set for a good run of south-southwest groundswell, with plenty of long-period action. It’s a very consistent spot and exposed to the swell, so when it’s on, it’s on. The optimum direction is SW, and we’ll see a lot of that over the coming days.

The standout of the whole period is without a doubt Sunday September 13th afternoon. We’re talking 6.2 ft of SSW swell with a 16-second period – that’s proper groundswell with heaps of energy (1857 combined energy). And get this: absolutely glassy, not a breath of wind. For a reef break, that’s as good as it gets. It’s bigger than 5 ft so it’s getting solid, but for experienced surfers, this is the session you wait for. Excellent conditions.

But if you want the biggest of the big, mark Saturday September 26th morning and afternoon. Swell hits 8.2 ft from the SSW with a 16-second period, and the energy is through the roof – over 3000! Again, glassy as a mirror. This is expert territory, though – over 8.2 ft, so only the crew with some serious experience should be out there. It’s a long-period swell, so it’ll be best at this reef, with longer lulls between sets making the paddle out a bit easier. A real Sunday-session-in-waiting.

Now, let’s walk through it chronologically.

The first surf comes in Friday September 11th. Morning has 3.6 ft from the south, period 12 seconds, with glassy conditions and light WSW wind. Combined energy is 538 – moderate. Afternoon drops to 2.3 ft but with a very long 18-second period from the SSW, and the energy jumps to 720. Still glassy. Nice clean starter, but not the highlight.

Saturday September 12th is a bit mixed. Morning has 4.6 ft SSW with a 14-second period, but a light cross-shore wind – not ideal. Afternoon cleans up nicely with 4.3 ft, glassy, and that same 14-second period. Good, not great.

Then we hit Sunday September 13th as mentioned – the first big standout. Morning is 5.2 ft with a 17-second period, but a light cross-onshore wind mucks it up a little. The afternoon is the one.

Monday September 14th morning still has 5.2 ft from the SW, but the wind is onshore and it’s marginal. Afternoon gets choppy with stronger cross-onshore breeze – poor conditions, avoid it.

Tuesday September 15th is interesting. Morning has 4.3 ft with an 18-second period – very long period, that’s groundswell – but light cross-onshore. Afternoon, though, glassy again with 5.2 ft from the SW. Excellent conditions for experienced crew.

Wednesday September 16th is another top contender. Morning glassy, 5.9 ft from the south, 16-second period, energy 2921. That’s strong. Afternoon glassy again, 7.5 ft SSW, 14 seconds. This is solid expert territory – fantastic.

Thursday September 17th morning is clean glass with 4.9 ft from the south, 13 seconds. Good session, but afternoon turns cloudy with offshore wind – marginal.

Friday September 18th drops off. Morning has 2.6 ft with a cross-off wind – clean but small. Afternoon is choppy.

Saturday September 19th and Sunday September 20th sees a return to glassy conditions. Swell stays around 3.3 to 4.3 ft from the SW, periods 14 to 16 seconds. Very clean, good fun for all levels.

Monday September 21st is clean again with 3.6 to 3.9 ft from the SW – a nice consistent run.

Tuesday September 22nd is another standout. Morning glassy, 4.9 ft from the SSW with an 18-second period and energy 1992 – that’s strong. Afternoon glassy too, 5.9 ft with a 17-second period, energy 2642. Excellent for experienced surfers.

Wednesday September 23rd sees the swell building but the wind turns cross-onshore. 7.2 ft in the morning, 6.2 ft in the afternoon – both strong energy, but the wind makes it marginal.

Thursday September 24th is blown out. 15.5 mph south wind in the morning, 12.4 mph in the afternoon – choppy and poor. Give
