The Lowdown
Alright folks, Rusty here, with a look at what's coming down the pipe for Black Rocks Jetty. We've got a solid run of swell on the horizon, so let's cut through the noise and get to the good stuff.
Right off the bat, the water is sitting at 77°, which is a touch warmer than normal for this time of year – a nice little bonus.
We kick off Thursday the 30th with a bit of a messy start. The morning is cross-shore and the swell is a jumbled 5ft from the SSW, with moderate energy (1098). The afternoon sees it bump up to 6ft, but the wind swings cross-onshore with rain showers. It's a bit of a washout for quality surfing.
Friday the 31st is where it starts to get interesting. The morning turns glassy with a clean 6ft SSW groundswell (16 seconds) and solid energy (1305). This is excellent for experienced surfers, but that long period will make it break a bit straight over the reef. The afternoon is just as good, with glassy conditions again. This is a real standout.
Saturday the 1st of August keeps the quality high. Morning sees a clean 6ft SSW swell, and the afternoon turns glassy. The energy is bumping up (1447), and the conditions are excellent for anyone who knows their way around a reef.
Sunday the 2nd starts glassy with a 4ft SSW swell, but the afternoon brings in a cross-on breeze. The swell drops off a bit from Monday the 3rd, with a 4ft SW swell in the morning, but it's still glassy and clean for a fun session.
The middle of the week, from the 4th to the 7th, sees the swell drop away to under 3ft. The energy is low (down to 216), and the wind is a bit messy. A few glassy windows, but nothing to get excited about.
Saturday the 8th of August brings a surprise. The morning is dead calm and glassy with a 3ft SW swell, but the period is a massive 17 seconds. That's very long period groundswell. The energy is moderate (539), and it's a great setup if you're on a point or reef, but the beach breaks will be straight. The afternoon stays glassy and the swell picks up to 4ft.
The surf builds nicely into the second week. Sunday the 9th is glassy in the morning with a 4ft SW swell. Monday the 10th of August is another true standout. The morning is dead calm and glassy, with a 5ft SW groundswell (15 seconds) and strong energy (1009). Excellent conditions for experienced surfers. The afternoon holds up with glassy conditions and 5ft swell. This is the pick of the longer-range forecast.
The 11th and 12th are good, with clean conditions and a mix of swells, but the wind gets a bit messy on the 11th afternoon. The 12th afternoon sees a nice 4ft S swell with a 18-second period and glassy conditions – a beautiful, long-period south groundswell.
The 13th of August is a bit mixed with onshore winds, but Friday the 14th of August comes back strong. The morning is glassy with a 5ft SSW groundswell (16 seconds) and strong energy (1310). This is excellent for experienced surfers and a fantastic way to wrap up the window.
So, to boil it down: the best on offer is Friday the 31st of July and Monday the 10th of August. Both have clean, glassy conditions, solid groundswell, and strong energy. Crowds at Black Rocks Jetty are possible, so get in early. Keep an eye on that long period stuff – it's a reef setup here, so it'll handle it fine.
Rusty.
