Black Rocks Jetty Surf Forecast and Surf Report

Alright, this is Rusty. Let’s have a look at what’s coming down the line.

We’ve got a bit of a slow start, but once it kicks in, there’s some serious grunt on the horizon. The first real action is a Friday morning glass-off at Black Rocks Jetty, with a tiny but clean 2ft southwest swell, a period of 19 seconds, and the water is a touch warmer than normal at 76°, which is a bit of a treat for this time of year. The combined energy is weak (463), so it’s a gentle session, perfect for a longboard or a late-morning cruise.

By Friday afternoon, the swell picks up to 5ft from the southwest, and the period drops to 17 seconds, still a quality groundswell. The wind is a light cross-off from the NNW, and the energy jumps to moderate (1221). It’s a clean, fun wave for experienced surfers. Saturday morning sees a slightly bigger 5ft swell, but the wind turns onshore from the WSW, and the energy is moderate (1094), making it a bit of a mess. Saturday afternoon and Sunday morning are pretty average, with onshore and cross-shore winds messing with the quality.

Sunday afternoon, the wind swings to a light cross-off again, and the swell drops to 3ft from the SSW, but with a long 17-second period, the energy is still moderate (800). It’s a clean little wave, but the real standout starts to build on Monday, September 7th. The swell pushes 7ft from the SSW, but the wind is a cross-on, so it’s a bit choppy. The energy is strong (1667).

Now, Tuesday, September 8th, is where things get interesting. The morning swell is 8ft from the SSW, with a 16-second period, and the energy is very strong (4093). The wind is cross-shore, so it’s a bit lumpy, but the size is there. Tuesday afternoon is the first real standout: 10ft from the SSW, 15-second period, and the energy is very strong (6564). The wind is light cross-shore, so it’s not perfect, but the power is massive. This is expert territory.

The absolute peak of the whole run is Wednesday, September 9th, afternoon. The swell is 10ft from the SSW, with a 17-second period, and the energy is massive (5903). The wind goes glassy, completely calm. This is a rare, epic window for experts only. The morning of that day is even bigger, 12ft, but with a slight cross-on breeze, so the afternoon is the pick.

After that, it settles down. Thursday, September 10th, is glassy all day, with 6ft in the morning and 5ft in the afternoon, both from the southwest. The energy is moderate (2112 and 1691). A great session for experienced surfers on clean, dropping swell.

The following week sees a few more pulses. September 16th, Wednesday afternoon, has a 10ft swell from the SSW, glassy wind, and very strong energy (4667). Another big, clean day for the experts. September 17th, Thursday afternoon, is glassy with a 7ft swell from the SSW, and the energy is strong (1563). A solid session.

The run fades out towards the end, with the last mention being September 19th, Saturday afternoon, with a 7ft swell from the SW, glassy wind, and strong energy (2237). A good way to finish the window.

If you’re a beginner, stay away from anything over 5ft, so pretty much all of the second week is out. For the experienced crew, the standout is absolutely Wednesday, September 9th, afternoon at Black Rocks Jetty. Massive 10ft south-southwest swell, glassy conditions, and energy through the roof. It doesn’t get much better than that on offer.
