The Lowdown

G’day, I’m Rusty. Alright, let’s have a look at what’s heading our way for the next couple weeks at Shark Island (Cronulla).

We’ve got a real mixed bag coming up. For the first week or more, the surf is mostly small and ordinary, with a lot of periods where the wind just doesn’t play ball. The water temp is sittin’ around 64°F, which is pretty much spot on for this time of year – nothing unusual there.

Kicking off Wednesday the 2nd, we’ve got tiny 2ft S swell with a 10-second period, but the energy is weak (108) and it’s just surfable, nothing to get excited about. Thursday the 3rd is a write-off – poor conditions both sessions with small waves and gusty cross-off winds. Friday the 4th morning is actually the first little highlight: a clean 4ft S swell, moderate wave energy (273), with light WNW cross-off winds. That’s your best early bet for a few fun ones, but it’s not a standout.

From there it gets pretty grim. Saturday the 5th through to Monday the 7th is a run of poor conditions – small waves, onshore or cross-onshore winds, and weak energy. Tuesday the 8th morning brings a jump in size to 6ft SSE swell, moderate energy (379), and clean conditions with cross-off wind, so that’s a decent look if you’re keen for a bigger push. But by the afternoon, it’s onshore again and messy.

Wednesday the 9th is ordinary, then Thursday the 10th morning gets solid but tricky – 8ft S swell with a huge 1182 energy reading, but strong cross-off winds and it’s a marginal call for the tide. That afternoon, the swell drops to 4ft but the period jumps to a very long 21 seconds (groundswell), and the energy goes through the roof at 2193. That’s a proper pulse, but that kind of long period at a reef break like this is what you want – it’ll wrap in nicely.

The true standout is Friday the 11th morning. Glassy conditions – no wind at all – with a solid 7ft SSE swell, 12-second period, and strong energy (1171). That’s a clean, powerful morning with offshore flow from the WSW. This is the pick of the whole run – a proper session. The afternoon turns onshore and messy though, so get in early.

After that, it’s a long, flat run of poor conditions from Saturday the 12th all the way through to the end of the window on Thursday the 17th. Mostly small, onshore, and weak. A few fleeting moments like Sunday the 13th morning with tiny 1ft waves, and Wednesday the 16th with a bit more size but cross-shore chop. Thursday the 17th morning offers a small clean window with 3ft S swell and offshore WSW wind, but it’s just ordinary.

So overall, if you’re keen, hit Friday the 4th morning for a clean little session, but the real gold is Friday the 11th morning – glassy, solid, and juicy. That’s the one to circle.

Rusty.
