The Lowdown

Alright, Rusty here, let’s get into the outlook for Shark Island (Cronulla) over the next sixteen days.

The first few days are mostly a miss. Thursday afternoon, September 10, brings a 7ft south swell at 10 seconds, but that cross-off south wind at 15 mph makes it a rough go. Water temp sits at 64°F, about average for the time of year. Friday morning, September 11, cleans up a bit with a 6ft SSE swell at 10 seconds and lighter cross-off winds at 6 mph. It’s better, but still not top shelf. Saturday morning, September 12, drops to 4ft south swell, but the cross-shore wind keeps it mediocre. Saturday afternoon through Monday, September 14, is a downward spiral of smaller swell and onshore winds.

We get a small window on Thursday morning, September 17 – glassy conditions with a 4ft south swell at 10 seconds. It’s surfable, nothing more.

The real standout comes on Saturday morning, September 19. That’s a heavy 10ft south swell at 11 seconds, with offshore WSW winds at 9 mph and massive wave energy (1944). This is serious groundswell – expert territory only. Saturday afternoon holds 7ft and clean with offshore SW winds (695 energy), which is another beauty for experienced surfers. Then Monday morning, September 21, brings glassy seas with a 5ft SE swell at 10 seconds and good energy (761) – another top-tier session.

After that, it tails off. Sunday, September 20, is big swell but ruined by strong onshore NE winds. The rest of the run is small, wind-affected, or poor quality. Thursday, September 24, has a 6ft ENE swell but it’s short-period at 7 seconds and messy – better for kite surfing.

So, your best bets are the morning of Saturday, September 19, and Monday morning, September 21. Crowds will be a factor when it’s clean and solid. Choose wisely.

Rusty.
