The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Black Rocks Jetty over the next couple of weeks.

The good news is, there’s surf on offer right from the get-go. The first few days are a bit of a mixed bag, but we’ve got a real standout window coming up that’s going to be something special. The water is sitting at a toasty 76.5°, which is a touch warmer than normal for this time of year, so you might not even need a full winter suit.

Friday, July 24th kicks things off with a clean 5-foot south swell in the morning. Wind is a light cross-off from the north, so it’ll be a bit textured but rideable. The energy is moderate (772). That afternoon, the wind drops to glassy and the swell switches to a cleaner 3.6-foot from the southwest, with a nice 14-second period – that’s a proper groundswell. The combined energy picks up to 823, and it’s looking like a lovely session for a log or a mid-length.

Saturday sees a smaller, cleaner 3.6-foot southwest groundswell (13 seconds) with a gentle offshore from the NE in the morning. The energy is still moderate (730). It’s a solid day for a cruise. The afternoon gets a bit bumpy with a cross-off wind, but it’s still surfable.

Sunday morning is tiny, only 2.6 feet, but that swell is from the SW with a massive 20-second period. That’s a very long period groundswell, which will wrap in nicely at this reef break and give you some long, clean lines. The energy is moderate (813). It’s a glassy morning, perfect for a longboard before the afternoon cross-onshore messes it up.

Monday, July 27th is the first big standout. This is expert territory. We’re looking at a solid 8.2-foot swell from the southwest, with a 16-second period. The combined energy jumps right up to 3493 – that’s strong wave energy. The wind is dead calm, glassy as a mirror all day. This is not for beginners – over 8 feet is only for the crew who know what they’re doing. But if you’ve got the skills, this is going to be an epic day at the jetty.

Tuesday, July 28th is another ripper. A 6.2-foot swell in the morning, building to 7.5 feet in the afternoon from the SSW, with a 17-second period. The energy is strong (2665 and 3229). Glassy conditions all day. Another one for the experienced surfers, but the quality will be top-tier.

Wednesday, July 29th stays excellent, with a 6.6-foot SSW groundswell in the morning (1560 energy) and 5.9 feet in the afternoon (1295 energy). Glassy. There’s a chance of rain showers in the afternoon, but who cares when the surf is that clean?

Thursday, July 30th is a tale of two halves. Glassy morning with a 3.3-foot slow swell (17 seconds, 1150 energy) – great for a relaxed session. The afternoon gets a bit of a south cross-onshore wind that messes with the surface on a 5.9-foot swell, so it’s a bit less appealing.

Friday, July 31st morning looks a bit bumpy with a cross-onshore wind on a 7.9-foot swell, but it cleans up in the afternoon as the wind goes glassy. That afternoon session is a beauty: 7.2 feet from the SSW, 16 seconds, and 2485 energy. That’s for the experts only.

The first week of August drops in size. Saturday and Sunday (1st and 2nd) are smaller, 4.9 feet down to 3 feet, but with glassy winds and long periods, they’ll be fantastic for a smaller board or a longboard. The energy is moderate (around 800-1000). Monday, August 3rd is a similar story, with a clean 4.3-foot SSW swell.

From Tuesday, August 4th onwards, the swell really backs off. The 4th and 5th are tiny, with 2.3 feet to 3 feet, and the energy drops to weak levels (297 and 366). The winds are often glassy, so it’s not terrible, just small. The 6th looks poor with a cross-onshore wind.

Friday, August 7th is a small, glassy finish to the week, with 2.6-foot waves. It’s a fun little day for the longboard crew.

Looking ahead to Saturday, August 8th, we get a bit of a pulse back. The morning is a bit cross-onshore, but the afternoon turns glassy and clean with a 4.3-foot southwest swell and a 16-second period. The energy is moderate (1023), and it’s a promising way to end the forecast period.

The absolute standouts are Monday the 27th and Tuesday the 28th – that’s the big, clean, powerful groundswell at Black Rocks Jetty. If you’re experienced, that’s the week to clear your schedule. The second
