Black Rocks Jetty Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what’s shaping up at Black Rocks Jetty.

We’ve got a decent run of swell on the horizon, but the start is a bit rough. Sunday morning the 5th of July kicks things off with a 4ft SW swell, 16-second period – that’s proper groundswell with plenty of energy (1472). The water’s sitting at 77°, which is about what you’d expect for this time of year. Problem is, the wind is cross-on from the south at 6 mph, so it’s not the cleanest. It’s surfable, but a bit of a grind. That afternoon the swell jumps to 7ft, but the wind stiffens to 9 mph from the SSW, and the energy is up at 2038 – still, it’s choppy and the conditions are marginal.

Monday the 6th is a write-off with strong cross-onshore winds (15-19 mph) and lumpy, messy waves. Tuesday the 7th is still pretty average – morning sees a 8ft S swell with 12-second period and moderate cross-wind, energy is high at 2571 but it’s cross-chop. The afternoon does bump up to 10ft and 3724 energy, but again, wind and chop spoil it.

Then we get a sweet little window. Wednesday the 8th of July swings in with glassy conditions – morning has a 6ft S swell, 11-second period, and the wind is a slight air from the ENE. That glassy surface will make it clean and fun. The energy is moderate at 743. Afternoon stays glassy with a 5ft S swell, 10-second period, and lighter energy at 529. Good times for a paddle if you pick your tides.

Thursday the 9th morning keeps the glassy vibe with a 3ft S swell, but the afternoon turns cross-on and a bit messy. Friday the 10th is a cracker – dead calm, glassy all day, with a 3ft SW swell (15-second period) in the morning and a 3ft SSW (16-second) in the afternoon. Energy is low but clean. Not huge, but if you like a long period, smooth wave, it’ll be a treat.

Now the standout is Saturday the 11th of July through to Monday the 13th. Saturday morning sees a 5ft SW swell, 15-second period, glassy, and the energy is up at 1125 – that’s good power. Afternoon gets better: 6ft SSW, 16-second period, energy at 1724. This is for more experienced surfers – the wave size is solid and the long period means it’ll be pushing hard. Sunday the 12th is even bigger: 8ft SW in the morning, 14-second period, energy at 2590 – that’s heavy, experts only. Afternoon holds at 8ft, still glassy. Monday the 13th then eases to 6ft SW, still excellent conditions. This whole stretch from Saturday through Monday is the best on offer – solid swell, glassy or clean wind, and the long period will favour the reef setup at Black Rocks Jetty. Crowds can happen here sometimes, so keep that in mind.

After that, things taper off. Tuesday the 14th and into the second week we get smaller, cleaner surf but nothing massive. The 14th has a 4ft SW swell in the morning, glassy, energy at 538. The afternoon drops to 4ft with a slight cross-on. Wednesday the 15th is tiny but clean – 2ft waves. Thursday the 16th back to a 4ft SSW swell, 15-second period, glassy in the morning. After that, it fades to knee-to-waist high stuff through the 17th to the 20th, with occasional glassy windows but low energy. Not really a standout period.

So if you’re after the best, aim for the 11th to the 13th of July – that’s where the juice is. You’ve got size, proper swell direction from the SW, and clean, glassy conditions. The rest is more of a slow burn with small, clean days here and there.

Rusty.
