The Lowdown
Alright, let’s break it down in feet and miles per hour. The water’s sitting a touch warmer than normal for the time of year, around 76°F, so you’ll be comfortable in a spring suit.
The first proper window we’re looking at is Black Rocks Jetty on Thursday the 24th of July. It’s not a classic, with a small 3ft SSW swell hanging around, but we’ve got clean conditions with a light cross-shore breeze. The swell’s a long-period groundswell at 15 seconds, so the sets will be well-spaced, and the reef setup is the right place for it. The combined energy is only moderate (744). It’s a marginal call, but the morning’s the pick.
Things start to wake up properly on Saturday the 26th of July. The morning sees a small 3ft SW swell, but the period is a very long 20 seconds, and with a light cross-offshore breeze, the lines will be clean. The energy is still moderate (785), but this is a proper reef wave, so it’ll handle the long period well. It’s a sneaky, small-wave day for the patient surfer.
Now, the real standout. Monday the 28th of July is the one you’ve been waiting for. We’ve got a solid 7ft SW groundswell with a 16-second period, and the morning is glassy. The combined energy is strong (2512), and the conditions are excellent for experienced surfers. This is a proper, powerful swell that will be too much for beginners, but for the crew who know what they’re doing, it’s going to be firing. The afternoon gets a light cross-on breeze, so the morning session is the absolute go.
The quality hangs in through Tuesday the 29th of July. The morning is glassy again with a 6ft SSW swell, 18-second period, and even stronger energy (2993). This is another excellent session for experienced surfers. The afternoon’s also glassy, with a bigger 8ft SSW swell, but with rain showers around. It’s still a standout.
Wednesday the 30th of July keeps the glassy theme going. The morning has a 6ft SSW swell, 14-second period, and moderate energy (1159). It’s excellent again, though the swell’s dropped a touch. The afternoon’s a bit smaller at 5ft, but still glassy and very good.
The first week of August delivers a nice run of clean conditions. Thursday the 31st of July has a 3ft SW swell with a 17-second period and glassy conditions – very good for the reef. The afternoon’s a 5ft SW swell, 16 seconds, and glassy, excellent for the experienced crew.
Friday the 1st of August sees a 6ft SSW groundswell, 15-second period, and glassy morning. The energy is strong (1604), and it’s excellent for experienced surfers. The afternoon turns a bit cross-onshore, so the morning wins.
The second week gets a bit more mixed. Saturday the 2nd of August has a 7ft SSW swell in the morning with a light onshore, which is a bit messy. The afternoon, however, is glassy with a 6ft SSW swell – another excellent session.
We’ve got a few smaller days after that, with Sunday the 3rd of August bringing a 4ft S swell, 12-second period, glassy, but only good, not incredible. The energy drops right off (480). Monday the 4th of August has a 4ft SSW swell, 14-second period, glassy, and very good (565).
The energy really fades by Tuesday the 5th of August, with a 3ft SW swell and weak energy (240). Glassy, but small. The rest of the week is very ordinary, with waves under 3ft and barely any energy.
Then, out of nowhere, Friday the 7th of August fires up again. The morning has a 6ft SW swell with a very long 21-second period. The combined energy is very strong (4178), and it’s glassy. This is excellent for experienced surfers. The afternoon is even bigger, with a 8ft SW swell, 20-second period, glassy, and energy at 4287. This is a proper, powerful, long-period groundswell – a real standout for the experts. The reef at Black Rocks Jetty is the perfect spot for it.
The crowds? Black Rocks Jetty can get busy sometimes, but with this kind of quality, you’ll want to be early.
