Is September Right for You?
Advantages
- Perfect autumn weather with comfortable 25°C (77°F) highs and cool 15°C (59°F) evenings - ideal for hiking Xishan (Western Hills) without summer's heat exhaustion
- Peak season for yunnan's famous wild mushrooms - local markets overflow with matsutake, morel, and porcini varieties that cost 40-60% less than other months

Considerations
- Afternoon rain showers occur 10 days per month, typically lasting 45-90 minutes between 2pm-4pm, disrupting outdoor sightseeing plans

- Temperature swings of 10°C (18°F) between day and night require layered clothing and make packing decisions challenging
