The Lowdown

G’day, Rusty here. Don’t get too jacked for the next week or so. We’ve got a long, slow run of small, messy waves ahead. The first real chance of a surf doesn’t even show up until the morning of Friday the 14th, but it’s nothing to write home about. You’ll be waiting over a week for anything decent.

For Friday the 14th, early morning at the crack of dawn is your only window. Shark Island (Cronulla) will have a weak 4ft S swell running at a short 8 seconds. The energy is pretty low (241), but the wind is light WSW at 3 mph, putting it cross-offshore and the surface will be clean. It’s surfable, but “very ordinary” is the word. It’s a reef break for advanced surfers, and sometimes there’s a crew out there. The water is sitting at 61°, which is a bit colder than average for this time of year.

That small window closes fast. By Friday afternoon, it drops to a messy 3ft with a cross-onshore breeze, and it’s all downhill from there. Saturday the 15th offers a slightly bigger 4ft SSE swell in the morning, but the wind swings S at 9 mph, and while it’s cross-off, the rain and marginal conditions make it a tough call. Saturday afternoon picks up to 5ft from the S, but the period drops to 7 seconds and the wind hits 16 mph – it’s going to be a lumpy, wind-affected mess. Sunday the 16th is tiny with a 1ft swell that has a super long 18 second period, but it’s coming from the wrong direction with a cross sea breeze. Just a write-off.

From Monday the 17th right through to Wednesday the 27th, it’s a graveyard of 3ft or smaller swells with cross-on or poor winds. There’s a glimmer on Monday the 24th – a sudden jump to a 6ft S swell with a 10 second period and strong energy (600), with a clean WSW cross-off breeze in the morning. It’s rated marginal, but it’s the first real pulse in over a week. Still, it’s not a standout.

The true standout is Thursday the 27th, over two weeks away. The morning session at Shark Island (Cronulla) fires up with a solid 7ft S swell, 9 second period, and a massive energy reading of 1371. The wind is offshore from the WSW at 9 mph, making for clean, peeling lines. This is one for experienced surfers only – anything over 7ft on a reef calls for respect. This is the best of the whole run, hands down. Friday the 28th morning holds a similar 7ft S swell with moderate offshore wind, still solid, but Thursday’s morning window is the one to circle on the calendar. Expect crowds to be likely at this advanced reef when it’s pumping.

Signing off,
Rusty
