The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got a solid run of surf on the way at Black Rocks Jetty, and it’s looking like a good period for anyone who can handle a bit of power. The water temp is sitting right where it should be for the time of year, so no surprises there.
The action kicks off Saturday morning, August 8th. Glassy conditions, a clean 4 ft SW swell with a super long 18-second period, and the combined energy is a solid 779 (moderate). It’s a reef setup, so that long-period groundswell will be stacking up nicely. This is the one to aim for – a real standout for the start of the window. The afternoon sees it bump up to 4 ft with the same clean glass, energy climbing to 1002 (moderate) – still excellent for experienced surfers.
Sunday, August 9th keeps the quality high. Morning glass, 4 ft SW at 15 seconds, and 619 energy. The wind is barely a whisper. Afternoon holds similar with a touch more energy at 726. Both sessions are glassy and clean.
Monday, August 10th has a tricky morning with a light cross-onshore breeze messing with the surface, but the afternoon cleans right back up. Glassy again, 4 ft SW at 16 seconds, and 923 energy. That’s a good call for the later session.
Tuesday, August 11th is a full day of glass. Zero wind. Swell hangs around 4 ft to 4 ft from the SW, period dropping slightly to 14 seconds. Energy is moderate (676 and 598). Clean, fun waves for the experienced crew.
Wednesday, August 12th has a morning with a light cross breeze, but the afternoon turns glassy again with 4 ft, 14-second SW swell and 588 energy. Good bet for the arvo.
Thursday, August 13th starts clean with a 4 ft SW swell, 480 energy, but the afternoon gets a bit messy with a 15 km/h cross-onshore and some chop. Not the best session.
Friday, August 14th sees a jump in size. Swell hits 6 ft in the morning and 6 ft in the afternoon, but the wind is cross-onshore both sessions, making it choppy. Energy is strong (1331 and 1790) but the wind is a problem. This is more of a kite day than a clean paddle session.
Now, Saturday, August 15th is a massive standout. The morning is glassy with a 6 ft SSW swell, a very long 18-second period, and energy at 3951 (strong). That’s a serious groundswell with perfect conditions. The afternoon is a bit bigger at 8 ft with a light cross breeze, but the morning is the pick. This is for experienced surfers only.
Sunday, August 16th is another cracker. Morning glass, 10 ft SSW swell, 16-second period, and 4220 energy. That’s a big, powerful swell. Afternoon holds 8 ft with glassy conditions and 3222 energy. Experts only out there – this is heavy.
Monday, August 17th drops back to 4 ft SW, but it’s clean and glassy with excellent energy (1341). A nice recovery day after the weekend’s size.
From Tuesday, August 18th through to the end of the run, the swell backs off, but there are still clean, glassy windows. The 21st of August (Friday) has a promising 3 ft S swell with an 18-second period and 695 energy – glassy morning, that’s a sneaky good session. The 23rd (Sunday) also has a clean 2 ft SW swell with a long 18-second period and 566 energy.
Overall, the standout days are Saturday morning, August 8th for the clean, long-period start, and Saturday morning, August 15th and Sunday, August 16th for the big, powerful groundswell with glassy conditions. Get on it.
Rusty.
