October trade-offs
- ↓Prices beginning to climb toward summer peak — October still reasonable but the trend is upward
- ↓October school holidays (two weeks, mid-month) bring domestic family crowds to beaches and tourist attractions
- ↓Jacaranda trees peak in late October–November: beautiful but an explosion of purple petals means footpath slipperiness
September trade-offs
- ↓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
