Black Rocks Jetty Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get straight into it for your local stretch. We’ve got a bit of a slow start, but don’t tune out—there’s some serious firepower coming down the line.

The Overall Pattern

It’s a quiet opening. Thursday is a write-off, with a messy cross-onshore wind and sloppy 5ft S swell. The energy is there, but it’s just not surfable. You’ll be better off doing something else. The wait is worth it, though. From Friday morning, the window opens and we get a solid run of clean, glassy conditions, especially for the reef set-up at Black Rocks Jetty. The standout window is the final week of July and the very start of August, with a strong pulse of SW groundswell.

The Week Ahead

Friday, 24 July – Things flip. The morning is glassy, with a nice 4ft SW groundswell rolling in at a long 15 seconds. The energy is moderate (808), and it’s aiming right at the optimum direction for this spot. This is clean, makeable surf. The afternoon gets a bit tricky with a light onshore and questionable tide, but the morning is the pick.

Saturday, 25 July – Another glassy morning, similar swell size at 4ft from the SW, period dropping a touch to 13 seconds. Still very clean, and the crowd factor is worth noting – this break can get busy, so get in early. The afternoon sees a slight cross-on wind, but it’s light.

Sunday, 26 July – A shift. The morning is clean with a cross-off wind, but the swell is a touch smaller at 3ft. The real gold is the afternoon. The wind is clean, the swell bumps up to 4ft, and the period jumps to 19 seconds. The energy is strong (1181). This is a long-period groundswell, which means glassy lines and long lulls between sets. It’s excellent for experienced surfers.

Monday, 27 July – This is the first big red-letter day. The swell jumps to 8ft from the SW, with a 16-second period. The energy is pumping (2944). Both morning and afternoon are glassy. At this size, it’s expert-only territory. The reef will be handling it well, but it’s powerful. The water temperature is about average for this time of year, so no surprises there.

Tuesday, 28 July – Still pumping. 6ft in the morning, glassy, excellent for experienced surfers. The afternoon picks up to 7ft from the SSW with a 17-second period. Energy is still very strong (2699). If you’re advanced, this is your window.

The Standout

The true standout is Friday, 31 July (morning) . It’s a week away, so keep an eye on the forecasts, but the data is clean. 8ft of SSW swell at 16 seconds, glassy as a mirror, and the energy is massive (3795). The wind is off the land, the direction is perfect for the reef. This is the best on offer. It’s a big, powerful, clean swell only for experienced surfers, but it’s the kind of session you remember.

The Second Week (August 1st onwards)

Saturday, 1 August – Swell backs off a touch to 6ft, still glassy in the morning. Good, but not the peak. The afternoon gets a bit scrappy with a light cross-onshore.

Sunday, 2 August – Dropping further. Cross-shore winds and a lumpy 4ft to 5ft. Nothing special.

Monday, 3 August – A clean 4ft in the morning, but the energy is fading. A decent session for the patient.

Tuesday, 4 August – Mixed bag. Slight cross-onshore in the morning, then glassy again in the afternoon with 4ft. Worth a look if you’re desperate.

Wednesday, 5 August – Small, clean 3ft in the morning, but the energy is weak (357). A fun little wave for a longboard or a fish.

Thursday, 6 August – Back to a clean 3ft, 15-second period in the morning. Not the power of the previous week, but clean.

Friday, 7 August – The run ends with a messy cross-shore 3ft swell. The long period (20 seconds) will make it a bit of a wait for waves at a beach break, but at this size, it’s not going to be too critical.

The Bottom Line

The first three days are a blank. Don’t bother. The real action is from Friday, 24 July through Tuesday, 28 July, and the absolute standout is Friday, 31 July. That’s your target. The second week offers a few clean, smaller windows, but nothing that compares to that last week of July.
