Black Rocks Jetty Surf Forecast and Surf Report

Alright mate, this is how it's looking in the old units.

Let’s talk about Black Rocks Jetty. It’s a reef break that’s very consistent and open to the SW swell. Water temp is sitting at 25°, just a touch warmer than usual for the season.

The run starts Saturday morning, July 4th. We’ve got a glassy 5ft SSW swell rolling in. The period is 13 seconds, the combined energy is a moderate 948, and with the wind flat calm, it’s going to be mirror-smooth. The break is advanced, and crowds are possible here, but Saturday morning early should keep the numbers down. This is a quality session if you’re keen.

Saturday afternoon gets a light breeze on the face – morning is the time to be out.

Sunday July 5th starts with a 4ft SW swell but the wind turns cross-onshore. The energy jumps to 1472, but the clean look is gone. Afternoon goes bigger, 7ft SW, but it’s cross-onshore and choppy. Hard pass.

Monday July 6th is just messy with cross-onshore wind and 7ft slop. Don’t bother.

Now, Tuesday July 7th. Morning sees a big 10ft S swell with a 12-second period and a cross-shore breeze. The combined energy is a strong 4661. That’s big and lumpy. This is expert territory only.

A big shift for the better on Wednesday July 8th, with glassy conditions all day long. The swell sits at 5ft in the morning and 5ft in the afternoon from the S. The energy is moderate (679 and 534), but those clean conditions will make it look like a dream. Great day for experienced surfers who know the reef.

Thursday July 9th and Friday July 10th stay glassy, with waves dropping from 3ft down to 3ft, then back up to 3ft on Friday afternoon with a 13-second period. The energy is low, but for a clean day on a longboard or a small craft? Could be a fun little session.

The real run begins Saturday July 11th. Glassy conditions, clear skies, and a 6ft SSW swell with a 14-second period. Combined energy is 1501, so it’s got some grunt. For advanced surfers only.

Sunday July 12th morning is the absolute beast: 10ft from the SSW with a 15-second period and 4686 in combined energy. Glassy. This is a serious, powerful groundswell on a reef. Only for experts with their A-game.

Monday July 13th keeps the quality up with 8ft SSW swell and glassy conditions in the morning, then a clean cross-offshore wind in the afternoon. Excellent both sessions.

Tuesday July 14th stays glassy with 6ft to 5ft SSW surf. Clean and fun for the advanced crew.

The quality wanes after that. Wednesday July 15th has glassy 4ft waves that fade into the afternoon. By Thursday July 16th the surf drops to 2ft, and the energy is weak at 126.

The 17th and 18th are very small and glassy but ordinary. A gap of three days with nothing worth paddling for.

Then Sunday July 19th brings a fun return: 5ft to 5ft SSW swell with glassy conditions and combined energy jumping back to 950 and 969. That’s a sweet, clean way to close the period.

So the one to book time off for? Sunday morning, July 12th. Big, clean, powerful swell. That’s the standout.

My runner up is Wednesday July 8th and Saturday July 11th for clean, strong swells.

Rusty.
