Nepal's climate varies dramatically with elevation, creating four distinct zones. The southern Terai plains experience tropical and subtropical conditions (20-40°C) year-round. The middle hill region (including Kathmandu and Pokhara) enjoys temperate weather with cool winters (5-20°C) and warm summers (20-30°C). The mountain region features alpine conditions with cold winters (-5 to 10°C) and mild summers. The high Himalayan region maintains arctic conditions year-round. Monsoon affects most regions from June through September, while October-November and March-May offer the most pleasant weather nationwide.
