Black Rocks Jetty Surf Forecast and Surf Report

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

First up, the water’s sitting at a warm 77° with a touch warmer than usual feel for this time of year, so that’s a nice bonus as you paddle out.

We’ve got a solid run of surf on the cards, kicking off Wednesday morning. It’s not a screamer right from the get-go, but it builds nicely. Wednesday morning sees a clean 7ft SSW swell rolling in with a long 14-second period – that’s proper groundswell energy. The wind is light cross-shore, so it’s workable, but the real magic happens Wednesday afternoon when it drops to glassy conditions. The swell eases a touch to 6ft, but that glassy surface makes Black Rocks Jetty look really inviting. The combined energy is pumping at 1676, which is strong, and this reef setup handles that direction well.

Thursday and Friday keep the run going with 5ft to 6ft SSW swell, and Friday is the standout. Friday morning and afternoon both serve up 6ft SSW swell at 15-16 seconds, with glassy conditions. That’s clean, lined-up, and powerful. The energy stays in the 1300s, so you’re feeling every bit of it. Saturday morning holds strong too with 6ft SSW at 15 seconds and clean cross-offshore wind. This whole stretch from Wednesday afternoon through Saturday morning is where you want to be in the water.

Now, the swell starts to taper a bit into Sunday and Monday, dropping from 5ft down to 4ft by Monday afternoon. Still some clean windows – Sunday morning is glassy with 4ft, and Tuesday morning has a tiny 3ft glassy pulse, but after that we hit a lull. From late Tuesday through the end of the first week, the swell drops under 3ft and the wind turns onshore or cross-on, so it gets pretty marginal. There’s a few small glassy moments on the 6th and 7th of August, but nothing to get excited about.

Then, just when you think it’s done, the second week shows promise. Around the 8th of August, we see a fresh SW groundswell pulse coming in at 3ft to 3ft but with a very long 17-18 second period. The energy jumps back to 646, and the wind is glassy. That’s the kind of long-period groundswell that really suits a reef like Black Rocks – the waves will be lined up with plenty of push between sets. The morning of the 11th of August looks even better: 5ft SW swell at 14 seconds with clean cross-offshore wind and energy back over 1000. That’s a legit standout in the longer range, but keep in mind it’s further out so not locked in just yet.

Overall, the best of the best is Friday, 31st July, with shoulder-high plus SSW groundswell, glassy conditions, and that reef handling the direction perfectly. It’s a spot that can get crowded sometimes, so get in early. The second standout to circle is Tuesday morning, 11th August, for a powerful SW pulse with clean winds.

Be aware that Black Rocks Jetty is an advanced reef break – when the swell’s over 5ft it’s no place for beginners, and at 7ft on Wednesday morning it’s serious. Those long-period swells (over 15 seconds) will really stand up on the reef, so respect the takeoff zone.

Enjoy the run, and stay sharp out there.
