What you gain in September
- ↑Spring wildflowers bloom across the Royal National Park (40 minutes south) and Blue Mountains — genuinely spectacular
- ↑Weather hits a sweet spot: 20°C, 7 hours of sun, lowest rainfall (69mm) — consistently excellent conditions
- ↑Prices still near winter lows as domestic tourism hasn't yet resumed summer pace
What you sacrifice
- ↓September is an underrated month, which means word is getting out — it's no longer the completely undiscovered secret it once was
- ↓Ocean is still cool (around 19°C) — swimming is possible but not the warm-water Bondi experience of January
- ↓Some restaurant and bar seasonal programming hasn't ramped up yet; a few venues still on winter hours
