Mbeya has a
subtropical highland climate (
Cwb, according to the
Köppen climate classification), with humid summers and dry winters. The general range of temperature is between during highlands mornings and during
lowland afternoons. The weather from June until October, is dry and cold. The heaviest rainfall occurs during the months of December to April, and annual rainfall averages approximately . The area around Mbeya town (especially in Tukuyu) enjoys abundant and reliable rainfall which stimulates abundant agriculture on the rich volcanic soils.
Mountain reserves and wildlife The area around Mbeya has been called the "
Scotland of Africa". The hills are clad in
heather and
bracken, but
botanically they are more closely related to the
Fynbos (fine bush) of South Africa's
Western Cape Province than the
Highlands of Scotland. The nearest mountain to Mbeya is
Loleza Mountain, which rises over and behind the town. Mbeya Peak is visible but some distance away.
Mount Rungwe is the highest mountain in the wider Mbeya region and it dominates the skyline for several kilometers around. It is composed of ten or more dormant
volcanic craters and domes. Rising above the small town of
Tukuyu, at , Rungwe is southern Tanzania's highest peak, and is among the highest in the country after some of the peaks in northern Tanzania such as
Mount Kilimanjaro () and
Mount Meru (). Mount Rungwe is surrounded by a catchment forest reserve that was gazetted in 1949. This forest reserve incorporates
montane forest, upper montane forest and montane grassland, with lesser amounts of
bushland and
heath at the upper elevations, found in low bushes along streams and at the edges of montane forest. The forest is home to a variety of significant forest flora and fauna, including the threatened
Abbott's duiker. The forest is regarded as an important bird area, with two species listed as vulnerable. The most notable creatures are
Rungwe bush vipers and
Colobus monkeys. Also ecologically important are the
Poroto Mountains, south-east of Mbeya. In 2005, a completely new species of large monkey, the
Kipunji, was discovered living in the southern highlands to the south-west of Mbeya. The Mbeya region has not yet been closely studied by scientists. The Kitulo Plateau, famous for its orchids and display of native flora is now within the designated
Kitulo National Park. Forests in the area, even in the reserves, continue to be encroached upon and degraded. However, there has also been extensive tree and forest planting, which ensures the local firewood supply. There is a small illicit trade in
orchid bulbs, which is thought to be endangering the survival of some species. == Transport ==
