Bhutan has a season for everyone. Kingdom stretches across all climatic zones, from the sub-tropical jungles in the south, to the moderate heights of 2000 – 5000 meters in the center and up to the alpine world of the towering Himalayas and glaciers in the north.
Winter:
Winter is dry and pleasant and makes it the best time of the year for bird watching in the jungles, village to village trekking in the lower altitudes or a bicycle trip along quiet mountain roads. The endangered Black Necked Cranes spend their winter in Bhutan.
Spring:
Spring brings the trekking season in moderate altitudes where spectacular rhododendron forests bloom. The largest monastic festivals, the Paro festival, take place. The temperature is pleasantly mild even up to the Alpine regions.
Summer:
Summer is the monsoon season but the settled areas of Central and Western Bhutan have pleasant summer temperatures. Rain falls regularly but is manageable with adequate planning and equipment. Treks in high mountain areas are characterized by mild temperatures, green meadows, and pastures of Blue Poppies and Edelweiss.
Autumn:
Autumn is the festive season in Bhutan. September and October have the highest number of festivals. Trekkers particularly enjoy the clear view of the mountains in October with low rainfall. Harvests, harvests rituals and festivals can add to your Bhutan experience.
