Kigali, with population of more than 1 million (2012), is the capital and largest city of Rwanda. It is situated near the geographic centre of the nation. The city has been the economic, cultural, and transport hub of Rwanda since it became capital at independence in 1962.
Rwanda has a temperate tropical highland climate, with lower temperatures than are typical for equatorial countries because of its high elevation. Kigali, in the centre of the country, has a typical daily temperature range between 12 and 27 °C (54 and 81 °F), with little variation through the year.
Rwanda has many lakes. The largest, Lake Kivu, is located in the midst of the volcanic peaks in the Virunga Mountains and forms part of the border with the Democratic Republic of the Congo. The lake has a surface area of 2,665 square kilometers (1,025 square miles) and reaches a maximum depth of 475 meters (1,558 feet).
