I visited Bhutan in June....weather was pleasant..and nice. Starting July monsoons start. You can visit Bhutan all year around...just that winters are cold.
Hi Khirabadi, October to December is the ideal time to visit Bhutan as the air is clear and fresh with sunny skies. January and February are colder, but from then until April the climate remains dry and pleasant and in late spring the famous rhododendrons bloom spectacularly, flooding the valleys with colour
Bhutan is one of the countries which can be visited throughout the year. All the seasons are good for visiting Bhutan, but, it can get extremely cold at higher altitudes. The best seasons to visit Bhutan are autumn and summer. However, December falls at a sweet spot. December marks the advent of winter in Bhutan, therefore the temperature remains from 8 to 15 degrees during the daytime and falls lower in the night. The climate is pleasant with no fear of snowfall or slippery pathways. Visit Now :-https://wanderon.in/blogs/best-time-to-visit-bhutan
