Black Rocks Jetty Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s look at what’s shaping up for Black Rocks Jetty.

We’ve got a decent run of surf on the horizon, but it’s not all for the faint-hearted. The water is sitting at 76° and running a touch warmer than normal for this time of year, so you’ll be comfortable in a spring suit.

The first real action hits Tuesday afternoon, September 8th. It’s a bit of a raw one – a solid 12ft SSW swell, but it’s coming in with a 15-second period from the south-east and a cross-shore wind. The energy is massive (8583), but the conditions are marginal, with a bit of chop. Honestly, this is a big, powerful reef setup that’s only for the very experienced. The crowd factor is there too, so it’ll be busy.

The standout window is Wednesday, September 9th. The morning is the pick of the entire forecast. The swell holds at 12ft from the SSW, but the period stretches to a very long 17 seconds, and the wind goes glassy from the south-southwest. The energy is still huge (8315), and the description says exceptional for experts. This is a serious, heavy groundswell at a very consistent reef break. It’s going to be a game of patience for the paddle out, but the waves will be lined up and powerful. If you’ve got the skill, this is the session. The afternoon holds similar size and period with a glassy easterly wind, but the energy dials back a touch (6138).

Thursday the 10th sees the swell drop to a more manageable 7ft, still with a long 14-second period and glassy conditions in the morning. This is a big step down in power (2082), making it excellent for experienced surfers, not just the elite. The afternoon drops further to 7ft from the SSE with a 13-second period, and the wind goes completely calm. It’s still a solid, clean wave.

From Friday the 11th through to the 14th, the swell backs off into the 2ft to 6ft range. The wind stays mostly light and favourable, so the quality will be high for a smaller, more user-friendly wave. The energy is lower (538 to 1022), but it’s clean and consistent.

Another true standout is Sunday, September 13th. The morning session brings back a solid 6ft swell from the SSW with a very long 17-second period and glassy conditions. The energy jumps back up to 2110. The sets will be powerful and clean, with long waits between them. This is a rewarding session for the experienced surfer. The afternoon gets a bit of a cross-on breeze, so stick to the morning.

The week of the 15th to the 22nd is a mix of solid, clean surf and some funky winds. The 15th and 16th have some excellent glassy windows with 6ft to 7ft SSW swell and good energy (1980 to 2642). The 21st and 22nd offer a similar story with clean 6ft to 6ft surf.

Looking way out, Wednesday, September 23rd is a big one, but it’s a long way off. The forecast shows a massive 10ft SSW swell arriving with a very long 20-second period and glassy conditions in the afternoon. The energy is extreme (6944). If this holds, it will be a legendary day for experts at this reef. It’s a promise, not a certainty, but it has my attention.

Rusty.
