The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming up for Shark Island (Cronulla). It’s going to be a bit of a mixed bag this fortnight, with a slow start, a couple of solid windows, and a big, powerful finale that’s only for the brave.

We kick off the forecast period on Tuesday, 21 July, but honestly, there’s nothing worth paddling out for. The next few days are full of small, weak, or onshore junk. The water temp is sitting at 63°F, which is about average for this time of year, nothing to write home about.

The first real chance to get wet comes on Friday morning, 24 July. This is the standout of the first week. A solid swell will be pushing in from the south at 8ft, with a period of 9 seconds. The wind will be a clean offshore from the southwest, making for excellent conditions. The combined energy is strong (1418), so this is a proper session. This is an advanced reef break, and with that size, it’s only for experienced surfers. Expect some crowds as it’s a popular spot.

Saturday morning, 25 July, drops a bit to 5ft from the south, but a moderate cross-offshore wind from the west keeps it clean. Surfable, but not a standout. Sunday morning, 26 July, offers a cleaner option with a 5ft south swell and a gentle offshore from the SSW. It’s a good, solid weekend morning.

After that, the surf goes quiet again from Monday, 27 July, right through to Wednesday, 29 July. Tiny, weak, and messy. A real lull in the middle of the week.

Now, looking ahead to the second week, things get serious. Thursday morning, 30 July, is a massive, powerful day. A south swell of 10ft with an 11-second period unloads, with a combined energy of 4097. The wind is light from the northwest, so it’s cross-shore but clean. This is heavy, and at a reef, it’s a serious expert-only wave. Friday morning, 31 July, is your best bet in this second window. A 10ft south swell, 12-second period, and a cross-offshore wind from the WNW. The energy is very strong (2722), and the conditions are reported as excellent. This is a big, powerful groundswell, and with that long period, it’s going to be walling up on the reef. Not for the faint-hearted.

The weekend of 1 August sees the swell start to ease, but it’s still solid. Saturday morning has 8ft from the south, and Sunday morning, 2 August, drops to 6ft with a gentle offshore from the SW. That Sunday morning is a real gem for the crew who want quality without the absolute max size.

From Monday, 3 August, onwards, the swell fades quickly and the wind turns onshore or messy. The last few days of the forecast are a write-off, so make the most of that Friday, 31 July, and Sunday, 2 August.

Rusty.
