March to May (Spring) and September to November (Autumn) is the best time to visit Bhutan. In spring, the weather is beautiful and pleasant. The flowers are in full bloom, and the scenery of the land is brilliant. The country also hosts various festivals during the spring such as the Paro and Punakha. Autumn, on the other hand, is also filled with clear and crisp blue skies. It is the peak season for the tourists to tour around bhutan.
In Summers from June to August, the temperatures reach 24-25 degree Celsius. From July onwards the southwest monsoons set in offsetting the heat but one has to carry a raincoat if out on a sightseeing.
In winter months of December -February witness the spell of the northeast monsoons. Snowfall is expected in late January and early February when the temperatures drop to the lowest.
Note The major tourist destinations in Bhutan are in the lower places, and hence can cater to tourists all year round. And in March to June and September to October, the climate is more pleasant. In high-season months (March, April, May, September, October, and November), the cost of visiting Bhutan is $250 US per person per day.
Bhutan in Peak Season (March to May and September to November)
Bhutan hence has two peak seasons. March to May, during Spring and September to November during fall, Bhutan sees a maximum rise in its tourist activities and industry. Tickets are hard to find if one plans a last minute holiday to Bhutan during its peak season. Hotels and resorts are booked to the hilt, and the nation is buzzing with numerous festivals.
The Bhutan government has set a 'Minimum Daily Package' rate for tours which differ in price according to seasons. For Indians travelling to Bhutan, the minimum daily package of 3 individuals is USD 250 per person per night during the peak season (March, April, May, September, October, and November). The package includes a 3-star accommodation, all meals, a licensed Bhutanese tour guide, all internal transports including air travel within the country and camping equipment and haulage for trekker
Bhutan in Offseason (June-August and December- February)
Bhutan also has two offseasons, namely from June-August and December- February. During the summers the monsoons often play havoc for tourists, and during the winters the temperatures are too low accompanied by snowfall. Most festivals also take place during the peak seasons; however, visiting Bhutan during the offseason has its advantages.
For one the crowd is much less and so are the tariffs and ticket prices. The Minimum Daily Package for January, February, June, July, August and December is USD 200. Plus, there is also still plenty to do and see in Bhutan during the summer and winter months, such as catching sight of the beautiful Black-Necked cranes in winter.
