Weather in September in Bhutan: Why This Month is Perfect for Travelers

Bhutan, in September, experiences a shift in weather, leaving behind the heavy rains of the monsoon and introducing drier, more comfortable conditions. It marks the beginning of Bhutan’s peak autumn season. Daytime temperatures are generally warm, averaging around 25°C (77°F), and tend to cool down significantly in the evening. While early September may still see sporadic showers, rainfall decreases substantially as the month progresses, making it easier to plan outdoor activities.

Weather in Bhutan in September

The average weather is around 24-25 degrees throughout September. During the beginning of September, it is still monsoon season in Bhutan. The rains usually occur during night time and will not pose a threat to morning tourism. However, this may not be suitable for trekking activities. Early September sees fewer visitors, making it easier to explore popular sites without large crowds. 

Late September onwards is autumn. The days are bright and sunny, making this the perfect time for travelers who want to engage in trekking and hiking. From mid-September, with about 18 sunny days on average and mild winds at 10-15 km/h, the weather is perfect for trekking and other outdoor adventures. The humidity levels also drop, adding to the comfort of travelers exploring the hills, valleys, and monasteries.

Costs and Crowds in September in Bhutan

From September begins Bhutan’s peak autumn season, bringing an increase in both crowds and travel costs. This month attracts numerous international visitors, especially towards the end of the month when clear skies and cooler temperatures offer ideal conditions for trekking, sightseeing, and experiencing Bhutan’s renowned festivals. Events like the Thimphu Tshechu draw significant crowds, leading to higher demand for accommodations, especially in areas hosting these celebrations. As a result, prices for hotels and tour packages often rise during this period, and travelers are advised to book in advance to secure better rates and preferred lodging options. While Bhutan enforces strict tourism policies to limit visitor numbers, September remains one of the busiest months, making it essential to plan early for a smooth and enjoyable experience.
