What is the best time of year to trek?
You can find good places to trek somewhere in the Himalayas at anytime of the year. However for most regions the best time is from October to May, with Oct-Nov having best weather for trekking. During the autumn nights are cold in the high Himalaya, but the bright sun makes for pleasant daytime temperature (20 degree centigrade to 5 centigrade in the night). Above 3500m temperature range goes down to -10 degree centigrade, and in winter (Dec-Jan) it is about 10 degrees colder.
