The Lowdown

Alright, Rusty here. Let’s talk about what’s coming up at Black Rocks Jetty. This is a reef setup, very consistent, exposed to the SW—so when the swell lines up, it can be a proper wave. Right now, the water is a noticeable 77°, which is much warmer than normal for this time of year, so you might not even need a spring suit.

Tuesday morning (August 25th) kicks things off in style. We’ve got a clean 6ft SSW swell with a 13-second period and glassy conditions—just a light westerly breeze—which is going to make for some really clean waves. The combined energy is solid at (1007), so there’s plenty of push. It’s a bit meaty for beginners but for experienced surfers this is a standout session.

Tuesday afternoon gets a little cross-on, and the swell drops slightly, so it’s not the pick of the day.

Wednesday morning (August 26th) is still good: clean, 5ft SW swell with a 12-second period, and a light cross-offshore wind from the NNW. That’s a solid session. But Wednesday afternoon is the real gem here—don’t miss it. The swell drops to 3ft but the period jumps to 18 seconds, and it’s glassy. That’s a long period groundswell, so the waves will be lined up, powerful for the size, and clean as glass. Combined energy (1144) is surprisingly punchy for the height. This is the kind of afternoon you tell your mates about.

Thursday the 27th sees a big jump: 10ft SSW swell with a 17-second period, but the wind is onshore and then cross-on with 12 mph winds by the afternoon. That’s expert-only territory—too big and onshore for most. The energy is huge (4932), but the quality is rough.

Friday the 28th is even bigger—13ft—with strong cross-onshore winds hitting 19 mph. The setup looks more interesting for kite surfing than paddle surfing. Combined energy is massive (8345) but messy.

Saturday the 29th is still big, 12ft in the morning with a light cross-on, but Saturday afternoon is a real standout: 10ft SSW swell, 15-second period, and glassy. The (3879) energy tells you it’s still a serious wave, but with no wind and that long period, it’s going to be clean and powerful. For experienced surfers only—this is the real deal.

Things settle down from Sunday the 30th to Tuesday September 1st—swell drops from 7ft to 3ft, mostly clean and glassy, but smaller and less exciting. Good for a longboard if you’re keen.

From Wednesday September 2nd to Friday September 4th, the swell drops right off—1ft to 2ft—with combined energy below 200 in places. There's a real gap in quality surf for several days here. Not much to write home about.

Saturday September 5th afternoon looks promising again: 4ft SW swell with a 15-second period and glassy conditions. Combined energy (757) is decent—good for a clean fun session.

Sunday September 6th is smaller and a bit choppy.

Then hold onto your board—Monday September 7th afternoon brings back 12ft SW swell with glassy wind, combined energy (4569). And Tuesday September 8th is the standout of the whole forecast: 13ft SSW swell, 18-second period, glassy offshore conditions. Combined energy hits (10004). This is exceptional, expert-level surf. If you’ve got the skill, this is the session. Wednesday September 9th keeps it clean with 10ft and 8ft SSW swells, glassy—more quality.

So, the best bets: Wednesday August 26th afternoon for a clean long-period groundswell, and Tuesday September 8th for the big, glassy, powerful stuff. Crowds are possible at times, so keep an eye out.

Rusty.
