Black Rocks Jetty Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what’s coming our way.

The next couple of days are a bit of a write-off, but we’ve got a cracking run of surf lined up after that. The swell is from the south-west, which is the money direction for Black Rocks Jetty. We’re looking at a long stretch of clean conditions, especially from Friday the 24th right through to early August. The water temp is sitting at roughly what you’d expect for this time of year, so nothing out of the ordinary there.

Wednesday the 22nd and Thursday the 23rd? Leave it. It’s small, crossed-up, and choppy. The wind is all wrong, and the wave energy is moderate at best (961 and 836 on the energy scale). Not worth paddling out.

Then things flip. Friday the 24th morning, it’s glassy as a mirror with a clean 4ft SW groundswell (15-second period). The energy is moderate (828), but with that period and offshore wind, the reef will be offering up some proper little peelers. It’ll be clean all day.

Saturday the 25th keeps that good run going. Another glassy morning, 4ft SW swell, and then a light cross-off breeze in the arvo keeps things tidy. Crowds can be an issue here sometimes, but the quality makes up for it.

Sunday the 26th gets a bit weird. The swell period jumps right up to 21 seconds, but the height drops to 3ft in the morning. That long-period groundswell will be making waves, but with that energy level flirting with being strong (901 and then 2074 in the arvo), it might be a bit inconsistent and tricky to line up, especially on a reef. Not the pick of the week.

Now, Monday the 27th – this is the true standout. A solid 8ft SW swell rolls in with a 13-second period and glassy conditions. The combined energy is pumping hard at 3937. That’s serious wave energy. This is excellent surf, but it’s for experienced surfers only – anything over 8ft on a reef demands respect. Tuesday the 28th is a close second, with 7ft to 7ft SSW swell and glassy conditions all day (energy at 2522). These two days are the absolute apex of the window.

We get a bit of a drop-off through Wednesday the 29th and Thursday the 30th, but it’s still clean and surfable with 4ft to 5ft swell and that glassy wind. Good for a longboard or a fun shortboard.

Friday the 31st sees another big pulse, with 7ft SW swell and glassy in the morning – another one for the advanced crew. Saturday the 1st of August is much the same, big swell and glassy. There’s another strong pulse on Monday the 3rd of August at 7ft.

A quick note: across this whole run, the swell period is often well over 11 seconds, and sometimes even over 15. That’s proper groundswell. It’s going to hold up well and offer some long, lined-up walls off the reef, but expect longer waits between sets.

The only real downside is the back half of the second week. Around Tuesday the 4th and Wednesday the 5th of August, the wind swings onshore and brings in the chop with 3ft to 4ft swell. Energy is moderate but the quality is poor – not worth it.

So, to sum it up: the absolute standouts are Monday the 27th of July and Tuesday the 28th of July, with excellent, clean, 6ft to 8ft SW groundswell. Get on it if you’ve got the skills. Friday the 31st and Saturday the 1st of August are also top-tier for the advanced crowd.
