Zambia is located on the plateau of Central Africa, between 1000–1600 m above sea level. The average altitude of 1200 m generally has a moderate climate. The climate of Zambia is tropical, modified by elevation. In the Köppen climate classification, most of the country is classified as humid subtropical or tropical wet and dry, with small stretches of semi-arid steppe climate in the south-west and along the Zambezi valley.
There are two main seasons, the rainy season (November to April) corresponding to summer, and the dry season (May/June to October/November), corresponding to winter. The dry season is subdivided into the cool dry season (May/June to August), and the hot dry season (September to October/November). The modifying influence of altitude gives the country pleasant subtropical weather rather than tropical conditions during the cool season of May to August. However, average monthly temperatures remain above 20 °C (68 °F) over most of the country for eight or more months of the year.
