The Lowdown
G’day, it’s Rusty. Let’s run through what’s on the cards for Shark Island (Cronulla). Water temps are around 63°, pretty much normal for this time of year.
Right now, it’s flat and quiet. Monday the 27th has a weak little 4ft S swell with a cross-off breeze – barely worth a look. Nothing decent on Monday or Tuesday. A real dry spell until things wake up.
Wednesday the 29th is tiny – 0.3ft leftovers and strong offshore wind, but no real waves to ride. Then Thursday the 30th morning is the one. A solid 8ft S swell with a 10-second period, light offshore SW wind, and clean conditions. Combined energy is 1534 – that’s proper power. This is expert-only, it’s a reef, and it’s gonna be heavy. If you’re advanced, this is the pick of the whole run. Crowds can show sometimes, but on a day like this, only the serious ones will be out.
Friday the 31st morning still has a good 7ft S swell with light offshore wind – quality but easing. Through the weekend it drops to 5ft to 5ft SSE swell with cross-off breezes – surfable but nothing special.
The first week of August is weak. Swell under 4ft, onshore or cross winds, and nothing to get excited about. A real lull.
Then Saturday the 8th afternoon throws up a 8ft E swell with a 9-second period and strong energy at 1623, but fresh cross-off winds keep it messy and marginal. Big and raw – only for the tough ones. Sunday the 9th afternoon cleans up a bit with 5ft E swell and light breezes, but it’s not a standout.
Into the second week, Monday the 10th morning has 6ft ENE swell but a cross-shore breeze and slight chop. The rest of the week drops off with poor conditions and strong winds. Honestly, apart from that Thursday the 30th morning, there’s nothing that’ll get you racing for the water. Long-range stuff is uncertain and messy.
That’s how it’s looking. Mark that Thursday the 30th if you’ve got the skills.
Rusty.
