October to December is the best time to visit Bhutan, with the weather at its driest and brightest. Autumn months (September-November) also see less rainfall and clear skies. Winter (December-February) is a photographer’s dream; prayer flags flutter against snowy backdrops. However, road closures are common and temperatures can drop below zero at night. Spring (March-May) can be wet, but the birds are in song and the wildflowers – including rhododendrons – are out, which can make it the best season to visit Bhutan for hiking. The soaking monsoon season (June-August) is best avoided, although some people still travel in the hottest month of July. Also note that Bhutan’s weather varies dramatically depending on the elevation.
