The Lowdown

Alright folks, Rusty here. Let’s get into it.

We’ve got a solid run of swell on the way for Black Rocks Jetty, starting Sunday the 26th of July. The window kicks off with a bit of a slow start, but hold tight – from Monday morning, things start to cook. The main energy comes from the SW and SSW directions, with a nice long-period groundswell that really favours this reef setup. The first few days see the combined energy building from a moderate 764 up to a strong 3827 (Monday afternoon), so there’s plenty of push in the water. The real standout window is Tuesday the 28th of July through to Friday the 31st of July, where we see consistent swell in the 5 ft to 7 ft range, with very clean conditions thanks to light or glassy winds. Water temperature is about average for this time of year, nothing unusual there.

The absolute best of the bunch is Tuesday morning, the 28th of July. You’ve got a 7 ft SW swell rolling in with a 15-second period – that’s proper groundswell, plenty of energy (2777) and glassy conditions with zero wind. This is a reef break, so that long period will wrap in beautifully, giving you some real memorable walls. It’s a little too big for the beginners, but for experienced surfers, this is as good as it gets. Crowds are possible here, so get in early.

Following that, Wednesday the 29th of July through Friday the 31st of July keeps the quality high. Wednesday morning offers another 7 ft SSW swell with glassy conditions, and the afternoons stay clean with 6 ft. Thursday and Friday both deliver 5 ft SW swell with a mix of glassy and offshore winds – all clean, all very consistent. The combined energy stays strong, between 1093 and 1536, so you’re getting solid, well-shaped waves without the battle.

There’s a slight drop-off over the first weekend of August, with swell settling to 5 ft, but still glassy and clean – a good option for the slightly less experienced. The energy drops to around 918 to 1124, so still fun, just not as punchy.

Into the second week, from Monday the 3rd of August onward, the swell stays consistent but a touch smaller, mostly in the 4 ft to 5 ft range. The standout in this period is Wednesday the 5th of August, with a 5 ft SSW swell, 18-second period, and glassy conditions – that’s a very long period groundswell, and combined energy of 1955. It’ll be a bit more drawn out and better at this reef, but expect some lulls between sets. Very promising, though not as certain as the first week. The rest of the second week is a mix of glassy mornings and onshore afternoons, with the swell tapering down to 2 ft by Monday the 10th of August.

If you’re a beginner, stick to the smaller days around 3 ft to 5 ft, like the 1st of August or the 8th of August. Anything over 5 ft is getting into intermediate territory, and over 8 ft is for experts only. The long period swells (over 11 seconds) mean better shape but longer gaps between sets, so keep that in mind.

Overall, this is a solid 16-day run for Black Rocks Jetty. The first week is the clear winner, with Tuesday the 28th of July the absolute standout. After that, it’s still very, very good, just a little less powerful. Don’t sleep on that Wednesday the 5th of August either – that long period could be a real treat.

Rusty.
