The Lowdown
Alright, let’s get into it.
The next couple of weeks are looking proper for Black Rocks Jetty. We’ve got a solid run of surf on the cards, but it ain’t all smooth sailing. The standout sessions are going to be for those who know what they’re doing. The water’s sitting right around average for this time of year, so no surprises there.
Wednesday the 9th is where it all kicks off, and it’s a big one. We’re talking a powerful SW groundswell pushing 13ft with a 17-second pulse. The energy in the water is strong at 8708. It’s glassy with no wind, making it an incredible, heavy session for experts only. This is the first real standout, a proper charging day. The afternoon backs off slightly to 12ft, still glassy, but still very much in the expert-only zone.
Thursday the 10th settles down a touch to a still solid 7ft SW swell, 14 seconds, with clean, glassy conditions. It’s a great day for experienced surfers to get a piece of it. The afternoon drops to 7ft with a SE direction, still clean and fun.
The weekend, the 11th and 12th, eases right off. We’re looking at small, clean waves in the 2ft to 5ft range. The period drops, and the energy is weak, around 604. It’ll be a fun time for a log or a fish, just not much push behind it. Still, it’s glassy and clean, so you can’t complain too much.
Sunday the 13th brings a new pulse, with the swell building back to 6-6ft, SSW, 16-17 seconds. The morning is clean with slight air, but the afternoon gets a touch of cross-on wind that takes the shine off it.
Monday the 14th is a bit of a write-off on the quality front. The swell is still there, but the wind is on it, making it lumpy and cross-onshore.
The next real highlight is Wednesday the 16th. A strong SW groundswell at 8ft, 15 seconds, with clean, glassy conditions. The energy is back up around 2933. This is another day for the more experienced crew. The afternoon maintains size but picks up some cross-shore wind.
We then see a slight dip on the 17th, with the swell dropping to 7ft and bumpier, cross-onshore winds.
Friday the 18th and Saturday the 19th see the conditions clean right up. The swell is a bit smaller, around 4–5ft, but it remains a clean SW groundswell with nice long 19-20 second periods. The mornings are glassy, and the arvos are clean with a light cross-off breeze. This is a great, fun stretch for all levels.
Sunday the 20th offers some cleaner, offshore winds with a 5ft SW swell. It’s looking like the best of the smaller days.
Monday the 21st is another goodie, with the swell nudging back up to 5ft, SW, 17 seconds, and clean conditions. Another solid day for experienced surfers.
We get a touch of onshore junk on Tuesday the 22nd day, with 8ft of SW swell getting chopped up.
Then, the finale on Thursday the 24th. We’re looking at a proper slug of SW groundswell at 10ft, 16 seconds, with clean, glassy conditions and very strong energy at 5286. It’s a huge, powerful day and one for experts only. This one is for the crew who want a proper end to the run.
Alright, keep an eye on the charts, that long-range Thursday looks special.
