#1 of 12 months
Best match

May trade-offs
- ↓Vivid Sydney (late May) brings major crowds to Circular Quay on peak evenings — arrive early or off-peak
- ↓Rainfall is still elevated at 122mm — pack layers and a jacket for variable weather
- ↓Beaches are off-season: Bondi is quiet and pleasant but the ocean is now 19°C — swimming is for the determined
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
