Black Rocks Jetty Surf Forecast and Surf Report

Alright, let’s get into it. This is Rusty, and I’m looking at the next couple of weeks here at Black Rocks Jetty. This spot is a reef break, exposed to the south-west swell, and it’s looking like a bit of a slow-burner, but when it fires, it’s gonna be a stunner.

The water temp is sitting about average for the time of year, nothing too wild.

Alright, we’ve got a bit of a quiet start. Friday the 17th is a bit of a tease. Morning glass-off with a 2 ft S swell (367 combined energy), clean and glassy – that’s about as good as it gets for a small wave. But it’s small. The afternoon gets blown out by a 12 mph onshore wind, so don’t bother.

Saturday the 18th and Sunday the 19th are a bit of a mixed bag. Saturday has onshore wind and dropping swell, not great. Sunday morning shows a bit more promise with a glassy 3 ft SW swell, 16 seconds period, and 484 combined energy. That’s a clean little wave, but still small.

Now, here’s where it gets interesting. Monday the 20th is the first real standout. The morning brings a clean 6 ft SW swell at 14 seconds, with glassy conditions. That’s a solid wave for anyone with a bit of experience. The afternoon gets even better: 7 ft SSW swell, glassy, clean, and 1,606 combined energy. That’s the best of the first week, no question.

Tuesday the 21st holds on with a 6 ft SSW swell in the morning, clean with cross-off wind, but it goes onshore in the afternoon. Good for a morning session. The rest of the week through to Thursday the 24th is a bit of a roll with smaller, clean swells in the morning, but nothing that’s going to blow your mind.

Friday the 24th and Saturday the 25th are a bit of a lull, with lighter swell and mixed winds. You’ll get some clean windows, but it’s not the main event.

Hold onto your board, because Monday the 27th of July is the big one. A massive 10 ft SW groundswell, with a 20-second period – that’s a very long period groundswell. The combined energy is 6,360, which is immense. The morning is glassy. This is a serious, expert-only wave. The power is huge, and with that period, it’s going to be a proper freight train. This is the absolute standout of the entire outlook. The afternoon is also glassy, with 10 ft at 18 seconds – still huge.

Tuesday the 28th is still offering big, clean waves for experienced surfers, with 8 ft to 8 ft SW swell, but the wind gets a bit stronger. It’s cross-off, so it’s clean, but it’s a step down from Monday.

After that, from Wednesday the 29th through to the end of the run, it’s a mix of big, powerful swell and onshore or cross-onshore wind. The 30th and 31st of July are looking poor with strong, lumpy onshore winds, and that big swell will be a messy, dangerous beast. The 1st of August brings a bit of a drop in size, but still messy.

The takeaway: If you’re an expert, Monday the 27th of July is your day. That’s the one to circle. The first week’s best is Monday the 20th of July for a bigger, clean swell. For the rest, it’s a lot of waiting for the magic to happen.
