The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s shaping up ahead of us. The first few days are a bit of a write-off, so don’t stress about rushing out. We’re looking at a slow start, but there’s a real pulse of energy coming through later in the period that’s worth circling on the calendar.
For the first few days, from Tuesday through Thursday, it’s pretty ordinary. Small, weak ENE swell with onshore or cross-shore winds making a mess of things. The combined energy is low, under 400 (377), and the conditions are just not there. Wednesday morning might offer a tiny window with a clean 3ft wave from the ENE, but it’s very ordinary. Honestly, leave the board in the shed.
Things start to get interesting on Friday, the 24th of July. The morning brings a solid jump in size. We’re looking at a 7ft south swell, with a clean offshore wind blowing from the SW. The energy is pumping at 1264, and the conditions are set to be very good. This is a strong, punchy swell for the advanced crew. The water temp is sitting at 63°, which is about average for the time of year, nothing weird there.
Friday afternoon drops off a bit with the wind swinging onshore, but the real standout is waiting for us. Wednesday the 29th of July. Mark it down. The morning delivers a hefty 10ft south swell, with a clean offshore breeze from the SW. This is big, powerful stuff – the combined energy is a massive 2154. This is for experts only. The reef at Shark Island (Cronulla) will be handling that south swell really well, but it’s going to be a handful. If you’re not comfortable in solid, critical waves, sit this one out.
The morning of Thursday the 30th of July is also a strong one, with an 8ft south swell and light offshore winds, but the energy is dropping slightly to 1669. Still excellent for experienced surfers.
Beyond that, there’s a smaller but clean run on the 1st of August. Saturday morning looks glassy with a 5ft SE swell, which is a nice size for a good session without the chaos. The wind is dead calm, so it’ll be clean as a whistle. That’s a solid option for a weekend paddle.
The rest of the period into early August drops off again, with onshore winds and small, weak swell. Don’t get your hopes up for the first week of August.
So, the pick of the bunch is the 29th of July for the big, powerful south swell. If that’s too heavy, the 24th of July morning is a great alternative, and the 1st of August morning is a solid, clean option for a fun session.
Stay safe out there.
Rusty.
