The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a solid run of swell coming down the line for Black Rocks Jetty, but you’re gonna need to pick your moments.
This reef setup is a consistent performer, and it’s on the exposed side, so it catches a lot of what the ocean throws at it. The water is sitting at 77°, which is a fair bit warmer than you’d expect for this time of year – about 4° above normal, so you can leave the thick rubber at home.
The swell kicks off on Monday, 24 August, with a solid 8ft SSW groundswell pumping in at 14 seconds. The energy is strong (1889), but the winds are glassy. That’s a clean, powerful wave for experienced surfers only. Tuesday morning sees a drop to 6ft, but still glassy with a long 13-second period – that’s your window for a slightly more manageable but still proper session. Tuesday afternoon and Wednesday morning stay clean with cross-offshore winds, but the swell drops a bit.
Then things get serious. Thursday, 27 August morning is the standout. It’s a glassy 10ft SSW swell with a very long 17-second period, and the energy is huge (4932). This is a big, powerful, clean groundswell. For a reef, this is going to be a treat for the experienced crew, but it’s a beast. The period is so long that the sets will be widely spaced, making the paddle out easier, but the waves themselves will be heavy and lined up.
The wind goes a bit funky Thursday afternoon, and Friday through Saturday sees the swell hold at 10-13ft, but with onshore and cross-shore winds. That’s a lot of energy (over 7000 on Friday morning) but with bumpy, choppy conditions. Honestly, for a paddle surfer, that’s a mess. With that much wind and swell on a reef, it’s looking more interesting for the kite crew than a clean paddle session.
Sunday, 30 August, brings a reset. The swell drops back to 7ft, and the winds go glassy again. Another excellent window for experienced surfers. That holds through Monday, 31 August, with clean 4-4ft conditions.
After that, the surf goes quiet. From Tuesday, 1 September, through to Friday, 4 September, it’s a flat spell. Waves are tiny, under 3ft, with weak energy. Don’t bother.
The run picks up again on Saturday, 5 September, with a good 5ft SW swell at 15 seconds and a gentle offshore breeze. That’s clean, lined-up, and a much better size for a wider range of surfers. Sunday, 6 September, morning offers another 6ft glassy session before the wind turns onshore. The following Monday, 7 September, is messy with rain and wind, but Tuesday, 8 September, looks like a gem again: 6ft SSW groundswell at 13 seconds, with glassy conditions. That’s a great way to finish the outlook.
Do not sleep on that Thursday, 27 August morning. That’s the one. Just make sure you’ve got the skills for it.
Stay salty,
Rusty
