The Lowdown

Alright, this is Rusty, your local surf reporter, bringing you the full outlook from the region.

First up, we’ve got Black Rocks Jetty, a reef break that’s very consistent and exposed to the south-west swell. The water temp is sitting at 77°, which is a touch warmer than normal for this time of year – a nice little bonus. Over the next few days, we’re looking at a pretty solid run of small, clean surf. Tuesday morning kicks off with a clean 3ft from the south, with a light cross-off breeze and decent energy (533). It’s a good start, but the real standout is the glassy, building swell later in the week.

Wednesday morning is glassy with 3ft, and that wind stays glassy through the afternoon. Thursday sees the same glassy conditions, with a sweet 3ft in the morning and a period stretching to 16 seconds – proper groundswell. The energy is building to 350. Things really start to hum on Friday morning with 4ft of clean, glassy surf from the south-west, energy jumping to 603. That’s a beautiful morning session.

The weekend looks even better. Saturday morning is glassy with 5ft, and the energy is getting up there (901). Sunday is where it gets serious for experienced surfers. We’re looking at 7ft from the south-south-west, glassy conditions, and the combined energy is a massive 1809. That’s a powerful groundswell, and for a reef break like this, it’s going to be a ripper. The following Monday holds 5ft glassy swell, and Tuesday morning is 6ft from the SSW with glassy conditions.

Now, the 27th of August we see a massive spike – 16ft from the south – but the wind is a fresh cross-shore at 19 mph, and the energy is an insane 15865. That’s way too big for this break, and it’s lumpy, so the setup looks more interesting for kite surfing than paddle surfing. That one is a pass for the surfboard.

The best of the best, the true standout, is Sunday the 23rd of August. That 7ft SSW groundswell with glassy wind and huge energy (1809) is an excellent call for experienced surfers. It’s going to be a clean, powerful, and memorable session at Black Rocks Jetty. Crowds are possible here, so get in early.

Later in the week, the 31st of August through 2nd of September keeps the high quality coming. The 31st is glassy with 5ft from the SSW, period pushing 17 seconds, and energy at 1505. The 1st of September is glassy again with 6ft, and the 2nd of September has a clean 6ft from the SW with a period of 18 seconds and energy at 2462. That’s all excellent, experienced-level surf, but it’s further out so a little less certain.

Overall, it’s a banger of a forecast. For the next week, the surf is on the small side but glassy and clean. Then it ramps up into a solid, powerful run for the experienced crew. Keep your eyes on that Sunday the 23rd and the start of September.

Rusty.
