Black Rocks Jetty Surf Forecast and Surf Report

G’day, Rusty here. We’ve got a solid run of surf coming our way at Black Rocks Jetty, kicking off from Tuesday the 28th of July. The standout window is the middle of this week, but honestly, there’s plenty to keep you keen.

Right off the bat, Tuesday morning the 28th is looking clean. You’ve got a solid 7ft groundswell from the SW, with a long period of 15 seconds. The wind is a light NNE cross-off at 3 mph, and the water is a touch warmer than normal at 76°, about 3° above average for this time of year. The combined wave energy is pumping at 2777, so there’s serious power in the water. This is a reef break, and it’s very consistent, but it’s an advanced spot—7ft on a reef isn’t for the faint-hearted. It’s glassy in the afternoon, with the swell dropping to 6ft on Wednesday and Thursday, but still with that long period, clean conditions, and very high energy. The morning of Wednesday the 29th is glassy, with a WNW wind at 3 mph, and the afternoon stays glassy with a W wind. Thursday the 30th is also glassy all day. This is about as good as it gets for a few days.

Friday the 31st holds 6ft groundswell, but the wind shifts to a cross-off NNE in the morning and picks up to 9 mph in the afternoon with some rain showers. Still clean, but a bit more breeze. Saturday the 1st of August is back to glassy conditions, both morning and afternoon, with 6ft of swell from the SSW. The energy is still strong at 1447. Sunday the 2nd of August starts glassy with 5ft, but the afternoon gets tricky—the wind goes onshore from the SSW, and the swell jumps to 6ft with a very long period of 17 seconds. That’s a lot of juice (1932 energy), but the onshore wind will mess it up for most. It’s still a reef, so the long period could work well, but the wind is a problem.

From Monday the 3rd of August, the swell drops to 4ft, and the energy starts to fade. The mornings are calm and glassy, but the power is slipping. By Tuesday the 4th, the swell is down to 2ft, and the conditions are only marginal. There’s a big gap from about the 5th of August to the 8th of August, with small, weak swell and cross-onshore winds most days. The energy is down in the hundreds, and the surf is only good for a paddle, not a proper session.

But then, from Sunday the 9th of August, it picks up again. The swell returns to 3ft from the SW, and the conditions are glassy or near glassy all the way through to Wednesday the 12th of August. The energy sits in the moderate range, around 500 to 800, and the period is 14 to 15 seconds. It’s not the big stuff from the start of the month, but it’s clean, consistent, and very surfable. The mornings are the best, with calm winds. The standout from this second week is Sunday the 9th and Monday the 10th of August, with glassy conditions all day and good, clean 3ft to 4ft groundswell. The energy is enough to get a few fun ones.

Overall, the best on offer is the first few days, particularly Tuesday the 28th of July and Wednesday the 29th of July. That’s the big, clean groundswell with the best wind. The second week has a promising run of glassy mornings starting the 9th of August, but it’s smaller. For the advanced crew, jump on that early window. For the rest, the later run is a nice, reliable option.

Rusty, signing off.
