The Lowdown
Alright, let’s break it down in feet and Fahrenheit for the old-school crew. Black Rocks Jetty is the only game in town, and it’s a reef for the advanced surfer – very consistent, so you know it’ll be breaking.
Water temp’s around 76°, which is a touch warmer than normal for July.
Monday afternoon, 20th July: some clouds, no wind, glassy. Swell’s 8ft from the SSW, 13-second period. Combined energy’s 1859 – that’s a solid push. Excellent for the experienced, but not for beginners.
Tuesday morning, 21st July: clear, glassy, 6ft SSW swell, 12-second period. Afternoon stays glassy with a slight breeze. Wednesday morning, 22nd July: glassy, 5ft S swell, 13-second period – that’s the early week pick. Afternoon gets cross-onshore and messy.
Thursday morning, 23rd July: glassy, 4ft S swell, 12-second period, energy down to 641. Still a good session. Friday and Saturday mornings have glassy conditions with 4ft to 5ft SW swells, periods 13 to 15 seconds – solid.
Sunday 26th July is a no-go – strong cross-onshore wind, energy 2204, but it’s choppy. Monday 27th July: 12ft SSW swell, 16-second period, but cross-onshore wind and energy at 6274 – experts only, and it’s blown out.
The real standout: 1st August (Saturday morning). Over a week away, but glassy, 10ft SSW swell, 16-second period, energy 3908. The afternoon’s glassy with 8ft. That’s the one to wait for.
Sunday 2nd August: clean, 5ft SSW swell with cross-offshore wind. Monday 3rd August: glassy, 5ft to 5ft SW swells with periods up to 18 seconds – that’s a long-period groundswell, perfect for the reef. Crowds are sometimes around, but for a spot this consistent, it’s worth the company.
Best on offer: 1st August for the big, clean swell, and Monday 3rd August for the long-period glass.
