September Weather in Mongolia
Is September Right for You?
Advantages
- Peak autumn colors in the Khangai Mountains - golden larches and red willows create spectacular photography conditions that last only 2-3 weeks
- Comfortable daytime temperatures of 15-18°C (59-64°F) perfect for horseback riding and hiking without summer's intense heat
- Post-summer clarity means visibility extends 100+ km (62+ miles) across the steppes - ideal for wildlife spotting and stargazing
- Final chance for comfortable ger camping before October's harsh weather - nighttime lows around 5°C (41°F) are manageable with proper gear
Considerations
- Rapid weather changes - temperature can drop 15°C (27°F) between afternoon and evening, requiring multiple clothing layers
- Some remote tourist gers close after September 15th as herder families prepare for winter migration
- Dust storms become more frequent as vegetation dies back - 3-4 major storms typically occur in September
