The Lowdown
G’day, it’s Rusty. Let’s talk about what’s coming up at Shark Island (Cronulla). It’s a reef break for advanced surfers only, so if you’re not comfortable with a bit of consequence, maybe give it a miss.
Water temp is sitting at 63°F, which is about normal for this time of year. Nothing weird happening.
First standout is Sunday morning, July 26th. We’ve got a clean 6ft swell from the south, period of 11 seconds, combined energy of 733—that’s solid. Wind is offshore from the WSW at 12 mph, so the waves should be clean and lined up. That’s the pick of the first week. Crowds can show up sometimes here, but the advanced-only break might keep it manageable.
Sunday afternoon goes dodgy with cross-on wind, so get in early.
Monday the 27th is just okay—3ft south swell, still clean, but weak energy at 172. Nothing to write home about.
Tuesday and Wednesday are flat and poor. Don’t bother.
Then Monday morning, August 3rd, we get another proper pulse: 6ft from the southeast, period 7 seconds, energy 674. Light WNW breeze keeps it clean. That’s your next session. It’s short period, so maybe a bit lumpy, but for size and clean conditions, it’s worth paddling out.
Second week trails off. Wednesday August 5th afternoon goes glassy with 5ft from the ESE and zero wind—clean but the direction’s not perfect for Shark Island (it prefers SE). Still, could snag a few.
Friday August 7th morning looks clean with 4ft east swell, 10 seconds, light WNW wind. Friday afternoon is glassy with 5ft east swell, 11 seconds—longer period groundswell, better shape, cleaner faces. That’s a solid option if you’re patient.
The rest of the second week is messy with cross-shore or onshore winds. Not worth it.
If you’re picking, Sunday morning July 26th wins for the combo of size and offshore wind. Monday morning August 3rd is the next best bet. Long period swells like August 7th can run a bit straight on reef, but Shark Island handles it alright.
Rusty.
