Table - best surf conditions forecast for Black Rocks Jetty over the next 16 days.
Alright, let’s get into it. Rusty here.
First up, we’re looking at Black Rocks Jetty, and right off the bat, the water’s sitting at a warm 76°, which is about average for this time of year. Nothing weird there.
The good news kicks off Sunday afternoon, July 12th, with a solid 8ft SW groundswell, but the wind is light onshore from the WSW, keeping it a bit messy. The energy is pumping hard at 2265, but the conditions are marginal. This one’s more for the experienced crew who don’t mind a bit of chop.
Monday morning, July 13th, is where it starts to get interesting. The swell drops slightly to 7ft from the SSW, but we get a clean offshore breeze from the NE. The energy is still strong at 1855, and the surf is looking excellent for the advanced surfers. That’s a proper standout window. Monday afternoon holds similar quality with a light cross-offshore wind and 7ft SSW swell.
Tuesday morning, July 14th, is a gem. The swell is 6ft from the SSW, and the wind goes dead calm – glassy as a mirror. The energy is still moderate at 995, and the conditions are very good. This is the best on offer for the early part of the week. Tuesday afternoon stays glassy with 5ft swell, but the wind shifts to a light S, keeping it clean.
The rest of the week into the weekend sees the swell drop steadily. Wednesday and Thursday have small, clean waves, but nothing to get too excited about. Friday the 17th has a weird mix – a clean morning with small 2ft S swell and a long 16-second period, but the afternoon turns onshore and messy.
Then we hit a big gap. From Saturday the 18th through to Wednesday the 22nd, the conditions are mostly marginal, with cross-onshore winds and deteriorating surf. The swell bumps up on Sunday the 19th afternoon with a 4ft SW swell and a very long 20-second period, but the wind is a moderate cross-onshore, making it choppy. Not great for paddle surfing.
The real standout, and the one to circle on your calendar, is Monday July 20th. The swell jumps to a solid 10ft from the SSW, with a strong 15-second period and massive energy at 3574. But – and it’s a big but – the wind is a moderate cross-onshore from the SSE, making it choppy. This is big, powerful, and only for experienced surfers who know the reef. Beginners, stay out of the water.
The next real highlight comes later. Friday July 24th afternoon sees a clean 4ft SSW swell with a light cross-offshore breeze, and the energy is back up to 1032. That’s a very good session for the advanced crew.
Then, Saturday July 25th is another absolute gem. The morning is glassy with 4ft SSW swell, but the afternoon is the standout – 5ft SSW swell, glassy conditions, and energy at 1206. The wind is light, the waves are clean, and this is the best surf of the entire outlook. Perfect for experienced surfers.
Sunday July 26th morning holds similar glassy conditions with 4ft SSW swell, but the afternoon gets choppy again.
Finally, Monday July 27th morning brings a massive 10ft SW swell with a very long 19-second period and energy through the roof at 6430. The wind is light cross-onshore, so it’s not perfect, but for the big wave specialists, this is a serious proposition. The crowd is likely to be there, as it’s a very consistent spot.
Overall, the best windows are Tuesday July 14th morning for clean, medium-sized waves, and Saturday July 25th afternoon for the absolute best combination of size, wind, and conditions. The big Monday July 20th and Monday July 27th swells are for the experts only.
Stay safe out there.
Rusty.

Information about the Black Rocks Jetty Surf forecast
The above surf forecast table for Black Rocks Jetty provides essential information for determining whether the surfing conditions will be good over the next 16 days.
