Black Rocks Jetty Surf Forecast and Surf Report

Alright, Rusty here again, but in feet and miles per hour for you lot. Let's break it down.

We’ve got a good run of surf coming into Black Rocks Jetty. It's a reef break, exposed to the SW, and it's a very consistent spot, so you know it's going to work. Water temp is about normal for the time of year.

First up, Friday the 3rd of July. Morning is glassy with a clean 5ft SW swell, period at a nice 14 seconds. The energy is moderate, 916. The afternoon stays glassy with a 4ft SW swell. Clean conditions.

Saturday the 4th is the same story. Glassy morning, 5ft from the SSW with a 13-second period. Afternoon stays glassy with a 5ft SSW swell. Solid start.

Sunday the 5th gets bigger but messier. Morning has a 5ft SW swell with a very long 17-second period and strong energy of 1912, but it's marginal because of the tide. By the afternoon, it's a 8ft SW swell with a cross-onshore wind at 9 mph. That's gonna chop it up. Energy is strong at 2653, but the quality is poor.

Monday the 6th is a write-off. Strong winds at 16 mph from the SSE, cross-onshore, with 7ft to 6ft of wind-affected swell. Choppy and poor.

Tuesday the 7th sees the swell jump. 10ft S swells with a 12-second period, very strong energy readings of 4296 and 3981. But the wind is cross-shore, making it marginal. That size is expert-only territory anyway.

Then we hit the good stuff again. Wednesday the 8th is looking prime. Glassy conditions in the morning with a 6ft S swell, 11-second period, moderate energy of 838. The afternoon is dead calm, glassy, with a 5ft S swell (667 energy). Perfect reef conditions.

Thursday the 9th is smaller. Glassy morning with a 4ft S swell, 10-second period. Afternoon gets a light cross-onshore with a 3ft swell.

Friday the 10th is small. Morning cross-onshore with a 3ft SW swell, but the afternoon swings back to glassy with a 3ft SW swell, 13-second period.

Now for a standout. Saturday the 11th. The afternoon is unreal. Dead calm, glassy, and a 6ft SW swell with a very long 16-second period. Strong energy at 1942. The report says excellent for experienced surfers. That long-period groundswell on a reef is going to produce some beautiful, walling waves. This is your best bet of the first week.

Sunday the 12th keeps the size. Morning has a 8ft SSW swell with light cross-onshore wind, but the afternoon is calm, glassy, and a 8ft SW swell with a 14-second period. Strong energy at 1922. Another excellent one for the experienced crew.

Monday the 13th is a bit messy with cross and cross-onshore winds on 7ft to 6ft SW swells.

Tuesday the 14th is the absolute king of the forecast. Both morning and afternoon are glassy, with a 10ft SSW swell and a very long 16-second period. The energy is very strong, 3978 and 4219. The report says excellent for experienced surfers. This is a serious, heavy, perfect-condition reef swell. Only for experts, but it’s the pick of the whole forecast.

Wednesday the 15th still has a glassy morning with a 8ft SSW swell, 15-second period, and strong energy of 2440. Excellent. Afternoon gets a light cross-onshore.

The run finishes from Thursday the 16th to Saturday the 18th with dropping size, from 5ft down to 2ft, but the wind stays mostly glassy. Clean, but small.

So, to wrap it up: the standout periods are the afternoons of Saturday the 11th and especially Tuesday the 14th of July. That Tuesday is the one. Glassy, massive, long-period groundswell on a reef – a dream for the advanced surfer.

Rusty.
