Bhutan has four distinct seasons. The southern plains close to Indian borders are warmer and more tropical than higher central valleys. The winter
months are fiercely cold subsiding around the end of February. Rhododendrons begin to bloom first in warmer east and by the height of Spring, the whole
kingdom is lush with spectacular flaming white, pink and red of the Rhododendron blossom. The annual monsoon affects south & central regions.
