The Lowdown
Alright, let’s get into it. Rusty here, and I’m looking at the next 16 days for Shark Island (Cronulla). To be honest, it’s a pretty bleak run for this reef break. We’ve got a real slow start, and the good windows are short and far between.
The first few days are a total write-off. Wednesday and Thursday morning have tiny little slop, 1ft to 3ft, with cross-off winds, but the energy is weak (36-152) and the conditions are just poor. Thursday afternoon gets a bit of height but onshore wind kills it. Friday and the weekend are the same story – small, weak, and messy. There’s a gap of almost a week with no real quality on offer.
The only real highlight I can see is the morning of Thursday, August 13th. The swell picks up to 5ft from the south, with a period of 8 seconds, and the wind is light and offshore from the south. That’ll get this reef at Shark Island (Cronulla) looking clean and lined up. The combined energy is moderate at 398, and it’s the first time we get a “good surf conditions” call. Friday morning, August 14th, is a repeat: 5ft south swell, light offshore wind, clean again. That’s your best bet for a proper session.
After that, the swell builds but the quality drops. Saturday, August 15th, sees 7ft south swell, but it’s marginal with moderate cross-off winds. That’s getting into the expert-only zone for size, but the wind isn’t perfect. The following week is a mix of medium-sized swell (5ft to 7ft) but with cross-shore or onshore winds, and the conditions are just “poor” or “marginal.” The energy is high (over 500 at times), but the wind is the enemy here.
Water temp is sitting at 62°, which is about 2° cooler than average for this time of year – nothing dramatic, just a bit of a winter chill.
If you’re not a dedicated reef rider, this setup could look more interesting for a kite session than a paddle session, especially on those bigger, windier days.
So, keep your eyes on the 13th and 14th of August. That’s your window. The rest is a long, slow grind.
Rusty.
