Although Tanzania lies within the tropical belt some parts of the hinterland contracts the expected temperatures. The coastal areas are mainly hot and humid with an average temperature of 30 Celsius. Sea winds modify this weather to a very pleasant one particularly during June to July. Rain Season is between March & May with the hottest months being October through to February. Light, washable summer clothes will normally suffice although warm wear may be required in the evening when traversing through some of the game parks located in the northern zone during the months of July to September.

Tanzania covers an area of 937,062 sq. km. and lies just south of the Equator. Of the 937,062 sq. km., 247,537 sq. km. are protected areas for wildlife. It borders Kenya and Uganda in the north, Zaire, Rwanda and Burundi in the west, Malawi, Zambia and Mozambique in the southThere are three distinct zones that contribute to the park's overall allure - Ngurdoto Crater, Mount Meru and the Momella Lakes. Formed some 15 million years ago, Ngurdoto Crater is today a steep sided pudding dish surrounded by forest. The floor is covered by lush swamps and riverine forest and is home to rhino, elephant, buffalo, baboon, warthog, olive baboon and the black and white colobus monkey. Mosses, ferns, lichen and orchids thrive here, giving way to mahogany, olive trees and wild date palms on the drier walls. Mount Meru (4,565m/14,990ft) is the fifth highest mountain in Africa - much more than the achievement, the climb is rewarding for the multitude of beautiful and interesting plants and animals found along its forested slopes. The Momella Lakes were formed as a result of the volcanic activity that gave birth to Mount Meru. Surrounded by mixed moor and grasslands, this group of seven alkaline lakes are fed by underground streams and are quite shallow. These beautiful lakes are the haunt of over 380 species of birds.

In the design of a Guest House for Missionaries in Dares-Salam, Tanzania, the Dutch architect Hubert-Jan Henket has used the building form and materials to modify the climate so as to produce comfortable conditions. The site lies close to the equator in a hot-humid zone, and continuous air movement is a necessary if comfortable conditions are to be achieved. As Dar-es-Salaam is on the coast, diurnal land and sea breezes are available to provide this air movement. The design fo the building exploits both these and the stack effect by which rising hot air within the building can be used to induce air movement.
