The Lowdown
Imperial Version
Alright, Rusty here. Let's size up the waves at Black Rocks Jetty.
We’ve got a bit of a slow start. The first thing worth paddling out for isn't until Sunday the 19th of July, and it’s pretty average. The water is running a touch warmer than usual for this time of year.
The real show starts Monday the 20th. Monday morning is the standout for the early week. We’re looking at a solid 7ft SSW swell, with a period of 14 seconds—that’s proper groundswell, a lot of energy behind it. The combined energy is a hefty 1987, and the wind is glassy from the north. This is a fantastic window for the experienced crew. The afternoon is just as good, with a similar 8ft swell and glassy conditions.
Tuesday the 21st keeps the clean conditions going with glassy offshore winds in the morning and afternoon. The swell drops a touch to 6ft, but it’s still a very clean, ridable wave. The period holds at 12 seconds, meaning good shape.
Wednesday the 22nd offers another glassy morning with a 5ft S swell, but the afternoon gets a bit of cross-onshore wind, making it less appealing.
The weekend of the 26th and 27th is where the heavy stuff arrives. Sunday the 26th afternoon sees a jump to 10ft of S swell, with a short period of 7 seconds and clean cross-offshore winds. The energy is massive at 3030. This is for experts only.
Then Monday the 27th is the absolute peak. The morning starts with 8ft, but the afternoon is the best of the whole run: 10ft of SSW groundswell with a very long 16-second period, pumping out a combined energy of 3669. The wind is glassy. This is a proper, powerful, clean swell. For the experienced crew only.
The first week of August also looks promising. Saturday the 1st of August morning has a glassy 10ft SSE swell, but the period is shorter at 10 seconds. That one is also for experts only.
Overall, if you’re an advanced surfer, the Monday the 27th afternoon is the one to circle on the calendar. The whole run from the 20th to the 28th has some excellent, clean windows, but the sheer size and power of that 27th afternoon is the standout.
Remember, with the longer period swells, the Black Rocks Jetty reef setup should handle the power well, but the size on the 26th, 27th, 31st, and 1st of August is not for the faint-hearted.
Rusty.
