G’day, this is Rusty.
We’ve got a solid run of swell headed our way, starting this Friday afternoon, 10 July, and it doesn’t really let up for the better part of a week. The standout spot is Black Rocks Jetty. It’s a very consistent reef break, so you know it’s going to be working. The water temperature is sitting at 77°, which is about a degree and a half warmer than normal for this time of year – feels like a bit of a treat.
The first real call is Friday afternoon. The swell is a clean 4 ft out of the SW with a decent 14-second period, and it’s glassy with no wind. The combined energy is moderate (557). It’s a good, mellow start to the run.
Saturday morning, 11 July, is where it gets interesting. The swell jumps to 6 ft from the SSW, with a 15-second period, and it’s dead calm. That’s proper groundswell, and the energy is solid (1236). This is for experienced surfers only – the size and power will be a handful. The afternoon sees a cross-on wind kick up, so get in early.
Sunday morning, 12 July, is the big one. Swell hits 8 ft from the SW, 15-second period, glassy conditions. The combined energy is massive (2699). This is all the way up there for experts only. It’s going to be a beast. The afternoon gets a bit messy with the cross-on breeze, so the morning session is the only one that counts.
From Monday 13 July through to Tuesday 14 July, we’ve got a steady diet of 7 ft to 6 ft SSW groundswell with glassy conditions. The energy remains strong (1736 down to 1093). These are excellent days for experienced surfers.
By Wednesday 15 July, the swell drops to 4 ft, and the quality starts to fade. The wind goes onshore in the afternoon. Thursday 16 July is small and ordinary, with only 2 ft to 2 ft. There’s a gap in the quality surf from Wednesday afternoon through to Friday 17 July.
Friday 17 July picks up a bit with a clean, glassy 3 ft swell from the S, but the period is a very long 16 seconds. That’s a long wait between sets, especially at a reef. The energy is moderate (381). Saturday 18 July is similar, small and glassy.
Sunday 19 July sees a return to form. The swell is 3 ft to 4 ft from the SW, 15-16 second period, and glassy. The energy climbs again (541 to 805). This is very good, clean surf.
Monday 20 July morning is the standout from the second week. A clean 4 ft SW swell with a 13-second period, glassy, and energy is strong (1037). It’s excellent for experienced surfers. The afternoon gets a cross-on wind, so it’s a morning-only window.
The rest of the week into 21 and 22 July sees a bigger, wind-affected swell (8 ft to 5 ft) with a strong cross-on breeze. The energy is high (2060 down to 813), but the quality is poor. It’s more of a mess than a surf session. Thursday 23 July and Friday 24 July clean up with glassy conditions and smaller swell (4 ft to 4 ft), but the energy is low.
The best of the second week is definitely Monday 20 July morning. For the long-range, Saturday 25 July morning looks promising with a 4 ft SSW swell and a clean cross-off wind, but it’s a bit further out, so keep an eye on it.
Signing off, Rusty.

Information about the Black Rocks Jetty Surf forecast
