Alright folks, Rusty here. Let’s have a proper look at what’s coming our way over the next couple of weeks.

Right from the get-go, Wednesday morning the 8th of July, the ocean turns it on at Black Rocks Jetty. We’ve got a clean 5ft south swell rolling in with a period of 11 seconds, and it’s glassy as a mirror with that light northerly breeze. The combined energy is sitting at a solid moderate 609, and the water’s sitting at a comfortable 77°, which is a touch warmer than usual for this time of year – feels good on the skin. This is a reef setup, so it’ll handle that long period groundswell nicely. Best on offer early on is Wednesday afternoon, with the wind dropping to dead calm and the swell holding at 5ft. It’s not massive, but with those glassy conditions and some decent energy, you’ll be getting some proper little nuggets.

Thursday the 9th is still clean with glassy conditions, but the swell backs off a bit – 3ft in the morning and dropping to 3ft by the afternoon. Still fun for a grovel, but nothing to write home about.

Friday the 10th is where it starts to get interesting again. The morning is small at 3ft, but the period jumps to a very long 15 seconds from the southwest. That’s proper groundswell energy. By the afternoon, that swell builds to 4ft, combined energy hits 564, and it’s still glassy. This is when those longer, more powerful waves start showing up on the reef.

Now, Saturday the 11th is the standout of the whole outlook. Morning sees 5ft of southwest swell with that same 15-second period, and combined energy is already punching at a strong 1093. The wind is light and cross-offshore, keeping things clean. But the real gem is Saturday afternoon: 6ft, still from the southwest, 15-second period, and it goes glassy again. Combined energy climbs to a powerful 1361. This is solid, high-quality reef surf for experienced surfers. Crowds can be an issue here sometimes, so if you want a peak to yourself, get in early.

Sunday the 12th gets bigger, but the wind swings cross-shore. 8ft in the morning and 8ft in the afternoon, but that cross-breeze messes with the surface. Combined energy is huge – over 2600 – but it’s a bit lumpy. For expert paddlers only at that size, and honestly, with the cross-chop, it might be more of a kite day than a paddle day.

Monday the 13th cleans up nicely. Morning is 6ft with cross-offshore wind, and the afternoon goes glassy again with the same 6ft. Excellent conditions for experienced surfers, with solid energy in the 1300-1400 range. Tuesday the 14th holds at 5ft with glassy conditions, but the swell direction tacks a little south-southwest.

From Wednesday the 15th, the swell slowly winds down through the rest of the week, staying mostly glassy but dropping below 3ft by Thursday the 16th. The 17th of July has a nice little spike: 5ft south swell with a very long 17-second period and glassy winds – combined energy over 1300. That one could surprise, especially on a reef like this.

The final week gets messy. From the 20th through the 23rd, the wind swings cross-onshore, and the consistent breeze makes it ugly. There’s a 7ft day on the 21st with a short period and choppy conditions – that’s a hard pass. A couple of days in that second week have a decent swell size, but the onshore wind kills the quality. Surfable, but not worth getting excited about.

Best on offer: Saturday the 11th of July, afternoon session at Black Rocks Jetty. That’s your call to arms.

Rusty.
