For clear skies and photo opportunities, the best time to visit Bhutan is October through December. This season is notable for a chance to witness rare black-necked cranes in Phobjikha Valley. Book in advance as autumn sees the influx of International travellers. A period between January and February is the coldest time of the year with occasional road closures, but Losar celebrations will warm you up. March and April are relatively dry and warm with an abundance of mesmerizing flowers in the valleys. From May on, temperatures start to rise, leading to the monsoon season from June to September. If you don’t mind the rain, summer is a good time to be in Bhutan with fewer tourists around.
