Malawi Geography, Climate & Nature

Geography

Malawi is a thin strip of the Great Rift Valley, which runs through the country from north to south; the lake fills the rift and makes up over three-quarters of the eastern boundary, and the Shire River flows down the valley from the lake's southern end to join the Zambezi in Mozambique. The country covers 118,484 square kilometres, is landlocked between Zambia, Tanzania and Mozambique, and extends southwards along the Shire into Mozambican territory.

Lake Malawi is 560 to 580 kilometres long and about 75 wide at its widest, the ninth-largest lake in the world by area and the fourth-largest freshwater lake by volume; in Africa only two are larger and one deeper. Likoma and its sister island lie a few kilometres off the Mozambican shore, entirely in Mozambican waters, and are Malawian exclaves. Cape Maclear on the southern shore is inside Lake Malawi National Park.

West and south of the lake the land rises to the plateaus: Zomba at 2,100 metres above the former capital, Nyika in the north 480 kilometres from Lilongwe, and Mulanje in the south-east, whose Sapitwa peak at 3,002 metres is the highest point in Malawi. The Chongoni rock art lies on the central plateau. The country has two World Heritage Sites.

Climate Patterns

Malawi's year has a wet half and a dry half. From November to April the weather is warm with equatorial rains and thunderstorms that reach their peak severity in late March; after March the rainfall diminishes rapidly, and from May to September wet mists drift from the highlands over the plateaus with almost no rain. Along the lake and in the lower Shire valley it is hot and humid from September to April, with daytime maxima around 27 to 29 degrees.

June to August is the cool season: the lake areas and the south are comfortably warm at about 23 degrees by day, but the rest of the country can be chilly at night, 10 to 14 degrees, and the high plateaus of Mulanje and Nyika fall to 6 to 8. Altitude sickness is a risk in parts of the country, and the cholera that produced the largest outbreak in Malawi's history in 2022 and 2023 rises again in the rainy season.

Habitats & Biodiversity

Malawi's biodiversity is concentrated in one lake. Lake Malawi holds more species of fish than any other lake in the world, at least 700 of them cichlids, and Lake Malawi National Park was inscribed as World Heritage in 1984 for a fish diversity of global importance: the mbuna of its rocky shores are, in UNESCO's words, an outstanding example of evolution at work. The lake is the ninth-largest in the world by area and the fourth-largest freshwater lake by volume, and its fish feed the country.

On land the story is restoration. Majete, managed by African Parks with the national parks department since 2003, regained black rhinos that year, 70 elephants from Liwonde in 2006 and the Big Five after; Liwonde's 548 square kilometres along 30 kilometres of the Shire have been under the same management since 2015. Nyika's plateau brings over 200 kinds of orchid into flower, and Mulanje's massif holds the last stands of the endangered Mulanje cypress and many species endemic to the mountain.

Wildlife & Birds

The fish are the wildlife: the mbuna cichlids of Lake Malawi's rocky shores, hundreds of species in colours that make a snorkel at Cape Maclear the equal of a reef, and the chambo on the plate. On land, Majete is Big Five country again -- black rhinos since 2003, elephants since 2006 -- and Liwonde's 30 kilometres of the Shire are hippo, crocodile and elephant water, both under African Parks and both best in the dry months when the game gathers. The Nyika plateau is orchid and antelope country at altitude; Mulanje is for the walkers and the cypress.

The advisories add the practical zoology: wildlife viewing poses risks, particularly on foot or at close range -- use reputable guides, keep a safe distance and leave the vehicle only when told; and this page says nothing about bilharzia in the lake or malaria in the lowlands because no sentence opened for it said so, though both are the questions to ask a travel clinic before swimming or sleeping without a net.
