Climate in Eastern Himalaya
The Himalayan climate varies according to elevation. It gets colder as elevation increases and gets wetter as the elevation drops. As a result the temperature and climatic changes in the Himalayan regions change very quickly. Rain is common in the Hills. It may come without notice, but except for the monsoon it may not last very long. During Monsoon (July – August) the region gets heavy shower and landslide is common occurrence. River crossing should be undertaken with extreme caution during this season. Every year a number of death takes place because of the high current of the river.
The two major seasons of the Himalayan region are winter and summer. During the winter the region receives the maximum snow with very icy temperatures. The snowline in Eastern Himalaya is higher than other areas. During Summer the snow starts at altitude of 17 to 18 thousand feet. During winter the snow line comes down sharply to altitude of 9 – 10 thousand feet. Summer is mild here, making the places quiet good summer holiday.
The weather in the lower Himalaya is suitable for tourists anytime during the year except July August when the Monsoon is in its full flurry. The winter months of January and February are not very popular because of the cold. But it is an ideal time if you want to visit the hills without jostling in tourist crowd. Besides this is the time when views of the mountains are the clearest. Higher altitude destinations are mostly closed to tourists during August September due to heavy rain and again in January February due to heavy snow. The rest of the year is fine for visiting these places.
