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.

A general guide to surfing at Black Rocks Jetty can be found by selecting the local surf guide option on the grey menu. Our Black Rocks Jetty surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Black Rocks Jetty may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
