The climate of Nepal
, a landlocked country in South Asia, is primarily characterized by three different climates, owing to its varied topography ranging from the lowland Terai plains to the lofty Himalayan peaks. This rich geographical diversity influences the overall weather conditions throughout the year. The Cwa climate, the Humid Subtropical Monsoon type, is mainly experienced in the lower altitude regions of Nepal. It features warm temperatures all year round, peaking in the summer months which are accompanied by substantial monsoonal rainfall.
Higher altitude regions, such as the mid-hills and lower Himalayan range, experience the Cwb or Subtropical Highland Oceanic climate, which presents with warm, rainy summers and dry, mild winters. The day-night temperature fluctuation can be quite significant in these areas. The Cfa climate, Humid Subtropical, is found in the relatively lower regions where the temperature and rainfall remain high throughout the year, with the summer season being notably hotter and rainier than winter.
