Bujumbura, formerly Usumbura, is the largest city and main port of Burundi. It ships most of the country's chief export, coffee, as well as cotton and tin ore. In late December 2018, Burundian president Pierre Nkurunziza announced that he would follow through on a 2007 promise to return Gitega its former political capital status, with Bujumbura remaining as economical capital and center of commerce. A vote in the Parliament of Burundi made the change official on 16 January 2019, with all branches of government expected to move to Gitega within three years.
Bujumbura is on the north-eastern shore of Lake Tanganyika, the second deepest lake in the world after Lake Baikal. The city also lies at the mouth of the Ruzizi River and two smaller rivers (Muha and Ntahangwa).
Bujumbura features a tropical savanna climate (Köppen: Aw)[5] with distinct wet and dry seasons. Its wet season is from October to April, while the dry season covers the remaining five months. Despite being located close to the equator, Bujumbura is not nearly as warm as one might expect, due to its altitude. Average temperatures are constant throughout the course of the year with the high temperature at around 29 °C (84 °F) and the low temperature at around 19 °C (66 °F).
