The Lowdown

Alright, Rusty here again. Let’s talk about what’s brewing at Black Rocks Jetty in feet and knots.

The first real surf shows up on Monday the 10th of August. The ocean’s got a bit of life, but the real big stuff lands later in the week. The water’s feeling a bit warm – about 77°, which is a touch warmer than usual for this time of year.

Monday afternoon sees a clean 4ft south-west swell, with a very long 16-second period. That’s proper groundswell, with a solid 923 energy rating. The wind is dead calm, glassy. The reef will be handling this beautifully. This is a standout session to open the run.

Tuesday the 11th keeps it clean – 4ft south-west swell, 14-second period, glassy all day. Wave energy around 610. Very consistent break, so you’ll get plenty.

Wednesday the 12th is a bit mixed – morning has a light onshore, but the afternoon cleans up to glassy with a 4ft swell.

Thursday the 13th is smaller, around 4ft, with some cross-shore bumps in the morning, but the afternoon glass-off makes it fun.

Friday the 14th of August is where the magic really kicks off. The morning hits with a solid 6ft south-west swell, glassy, 13-second period. 1237 energy – that’s strong. By the afternoon, the swell drops to 3ft, but the period stretches to a very long 21 seconds. Energy is even higher at 1488. Glassy and clean. This is the session to aim for – long, peeling lines on the reef.

Saturday the 15th of August is a big day. Morning has a 6ft south-south-west swell, 20-second period, and massive 2942 energy. Glassy. By the afternoon, it builds to 8ft, 18-second period, and a huge 3916 energy. This is expert territory.

Sunday the 16th holds at 8ft in the morning with clean cross-off wind. Still excellent, but big.

Second week sees the swell drop. Monday the 17th has a 4ft south-west swell, 16-second period, glassy in the afternoon – a nice, more mellow session.

From Tuesday 18th to Friday 21st, it’s small – 2ft to 3ft. Mostly clean, but small. Good for a longboard.

Friday the 21st afternoon has a 2ft south swell with a very long 20-second period and clean cross-off – a sneaky good little wave.

Sunday the 23rd of August morning perks up with a 3ft south swell, 17-second period, glassy. 903 energy. Very good.

Then Sunday the 23rd afternoon hits with a 7ft south swell and onshore wind – lumpy and rough.

The final big standout is Monday the 24th of August morning – a large 8ft south swell, 16-second period, clean cross-off wind. Energy is massive at 3102. Experts only.

After that, the 25th of August gets onshore with 30+ km/h winds and sloppy conditions.

Best of the whole window: Friday the 14th of August afternoon for quality, and Saturday the 15th of August morning for size and power.

Rusty.

A general guide to surfing at Black Rocks Jetty can be found by selecting the local surf guide option on the grey menu.
