Tanzania Weather by Month

Tanzania, located in East Africa, is renowned for its diverse geography, ranging from coastal plains and vast savannahs to highland plateaus and mountainous regions. It is bordered by Kenya and Uganda to the north, Rwanda, Burundi, and the Democratic Republic of Congo to the west, Zambia, Malawi, and Mozambique to the south, and the Indian Ocean to the east. Tanzania is home to Africa’s highest peak, Mount Kilimanjaro, as well as the Great Rift Valley and the iconic Serengeti Plains. The country also features one of the world’s largest freshwater lakes, Lake Victoria, and the expansive Lake Tanganyika.

Tanzania’s geography significantly influences its climate. The coastal regions along the Indian Ocean enjoy a tropical climate, while the highland areas experience more temperate conditions. The country has two main rainy seasons: the long rains (Masika), which occur from March to May, and the short rains (Vuli), from October to December. The dry seasons fall between June to October and January to February, though these patterns can vary slightly by region. Tanzania’s weather varies greatly depending on elevation and proximity to the coast or inland lakes.
