Black Rocks Jetty Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s coming down the line for us. We’re going to get a bit of a slow start, but this forecast has some real gems tucked away, especially for the more experienced crew.

The first few days are pretty quiet. Wednesday morning the 2nd is glassy but tiny, with just 1 ft of SW swell. The energy is weak (80), so it’s more of a paddle-around than a proper surf. Thursday is similar, with a touch more size but still nothing to write home about. The real wait is on.

Things start to get interesting by Friday the 4th. The morning glass is back, and the swell builds to 2 ft from the SW with a period of 19 seconds. That’s proper groundswell energy, and the combined energy jumps to 463 (moderate). The afternoon is even better, with 5 ft of SW swell, still glassy, and the energy cranks up to 1221 (strong). This is a solid window for experienced surfers at Black Rocks Jetty.

Saturday the 5th morning sees the swell push over 5 ft (5 ft from the SW), but the wind is onshore, so it’s more of a challenge than a treat. The water temp is a touch warmer than normal at 76°.

Sunday the 6th afternoon is a real standout. The wind goes glassy again, and we’ve got 4 ft of SW swell with a period of 13 seconds. The combined energy is 812 (strong). It’s clean, it’s got push, and this is the best of the early part of the outlook.

The following week gets serious. Monday the 7th sees the swell jump to 6 ft, but the wind is cross-onshore, so it’s messy. Tuesday the 8th is for experts only. The swell is 10 ft to 12 ft from the SSW, with a period of 15 seconds – that’s very long period energy. The combined energy readings are massive (5306 to 7246). These are big, powerful, shifting lines. If you’re in the water, you need to know what you’re doing. The wind is cross-shore, so it’s a raw, powerful ocean.

Wednesday the 9th is another highlight for the experienced surfer. Into the afternoon, the wind drops to glassy, and we have a solid 10 ft of SSW swell with a 17-second period. The energy is still very strong (4809). This is a world-class window for a reef break, but it’s not for the faint-hearted.

Thursday the 10th is a good drop-off. The swell is still a solid 7 ft in the morning, and the wind is glassy. The afternoon is even better, with 5 ft of SW swell and dead calm conditions. This is clean, powerful, and the kind of afternoon you’ll be telling stories about. The energy is still strong (1464).

After a few days of smaller, trickier conditions, we get a real treat on Monday the 14th of September. The afternoon sees a 4 ft swell from the SSW with a massive 22-second period. That’s a very long period groundswell. The combined energy is 1719 (strong). This will be a proper, clean, high-energy swell at the reef. The wind is cross-offshore, so it’ll be a beautiful, clean wave.

Tuesday the 15th is also a standout. The morning is glassy calm with a 8 ft SSW swell, 16-second period, and a combined energy of 2964 (very strong). This is a serious, powerful day for experts. The rest of the week continues to offer solid, glassy mornings, particularly on Wednesday the 16th and Thursday the 17th, with 6 ft to 8 ft of clean swell.

The standout sessions here are the afternoons of Friday the 4th, Sunday the 6th, and the whole of Monday the 14th and Tuesday the 15th. For the serious crew, Wednesday the 9th is also a massive, powerful day. Black Rocks Jetty is a reef break, and it’s very consistent, so it’s reliable. Crowds are possible, so get out there early for the best of it.

Rusty.
