The Lowdown
G’day, Rusty here. Let’s cut to it: Shark Island (Cronulla) is looking at a long, slow grind over the next two weeks. Water temp is 61°, which is a bit nippier than usual for this time of year, so break out the booties.
Right now, through Monday the 10th, it’s pretty ordinary. Sunday morning has a tiny 3ft ENE swell, but it’s crossed up by a NNW breeze, so it’s messy. It gets worse overnight—Monday sees a jump in energy (617) but it’s lumpy and cross-chopped, blown out by a fresh NNW wind. Not worth the paddle.
There’s a bit of a lull Tuesday and Wednesday. Tuesday afternoon cleans up nicely with glassy conditions and a weak 3ft south swell. It’s surfable but nothing to write home about. Wednesday’s a similar story—clean but weak and small.
Thursday the 13th shows a little more life. Morning has a 4ft south swell with a moderate offshore, and it’s clean, but it’s still not firing. The afternoon bumps up to 6ft, but the cross-off wind and questionable tides make it a gamble.
Then we hit a real dead patch from Friday afternoon all the way through to Tuesday the 18th. The swell drops, the winds get messy, and there’s nothing worth getting wet for. That’s a good week of just staring at the ocean.
Finally, things start to turn around on Wednesday the 19th. It’s still cross-shore, but the swell is building at 5-6ft with moderate energy. Then Thursday the 20th is the standout. You’ve got a clean 5-6ft east swell, light cross-off winds, and solid energy (396-462). This is your morning session—the sand will be looking friendly and the lines should be holding up. The swell direction is close to the optimum for this spot, so it should be working properly.
Keep an eye on Saturday the 22nd as the other real highlight. The morning has a 6ft ENE swell with a gentle offshore wind, and the energy is pumping (601). Afternoon cleans up even more with light winds and a slightly bigger 6ft. This is the pick of the bunch for the whole stretch. If you can only get out once, make it Saturday the 22nd.
After that, it fades again into Sunday and Monday with onshore slop and strong winds, and the window closes. So there’s your two chances: Thursday the 20th and Saturday the 22nd. Don’t hold your breath for much else.
Rusty out.
