The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming down the pipe for the next couple of weeks.

We’ve got a solid run of surf ahead, with a real standout weekend about a week and a half out. The forecast is built around one spot – Black Rocks Jetty – and it’s a very consistent reef break that handles South-West swell like a champ. Be aware, this is a spot for advanced surfers only, and it can get crowded sometimes.

The water is sitting at 77° right now, which is a touch warmer than normal for this time of year – a nice bonus.

We kick things off on Wednesday, August 5th. The afternoon sees a glassy 3 ft SW swell rolling in with a very long period of 15 seconds. The combined energy is moderate (381). It’s clean, but small. Thursday morning looks similar, a glassy 3 ft SW swell, with a 13-second period (283 energy). The wind is light and offshore, so it’s worth a paddle.

Friday, August 7th, starts glassy with a 3 ft SW swell. By the afternoon, the swell drops to 1 ft, but the period jumps up to 22 seconds, which is incredibly long. The energy is still moderate (349). This groundswell will wrap in nicely, but it’s small.

Then we get to the first real highlight. Saturday, August 8th, is a beauty. The morning is glassy, the swell climbs to 4 ft from the SW with an 18-second period, and the energy is strong (780). The afternoon is even better: 4 ft, 16-second period, clean glassy conditions, and energy climbing to 796. This is the best surf of the first week – clean, solid, and long-period groundswell.

Sunday the 9th has a bit of cross-onshore wind in the morning, but the afternoon cleans up to glassy with a 4 ft SW swell and 14-second period (560 energy). Monday the 10th is a bit messy with a light cross-onshore wind, but the swell holds at 4 ft.

Tuesday the 11th has a cleaner afternoon, going glassy with a 4 ft swell and 14-second period (599 energy). Wednesday the 12th is similar, with a glassy afternoon showing 4 ft SW swell.

Now, for the real standout. The action steps up on Saturday, August 15th. The afternoon is absolutely firing: a clean 6 ft SW swell, 18-second period, and the energy is very strong (2174). The wind is calm, it’s glassy. This is big, clean groundswell for experienced surfers only. Sunday the 16th morning is also a cracker: 7 ft SSW swell, 16-second period, glassy, with energy at 2050. This is expert territory, pure and simple.

After that, the swell holds through the start of the next week, with Monday the 17th seeing a 5 ft SSW swell, and Tuesday the 18th returning to glassy conditions with a 4 ft swell. The last few days of the run, from the 19th, show cleaner, smaller conditions, with glassy mornings and good energy.

No other breaks are on the menu, so if you’re an advanced surfer, Black Rocks Jetty is the only game in town. The swell pump around the 15th and 16th is the one to circle on the calendar. It’s a long way out, so keep an eye on it, but it’s looking like the best of the entire run.

Rusty.
