Kaza temperature remains immensely low compared to the rest of the country. This Himalayan town is known widely as a vast chilly desert with temperatures going down even below 0 degree Celsius during the winter season. Owing to this extremely harsh weather in Kaza and heavy snowfall, the primary entry points of the town – Kunzum Pass and Rohtang Pass – both get closed from the end of October until the first or second week of the month of June. The month of January is considered to be the coldest in the entire year with spine-chilling temperature averaging around -37oC.
