Dedza is about the same size as Norfolk – 40 miles north to south and
70 miles east to west. The western part is on the Central African Plateau
at an altitude of 1600m (5000ft). Higher mountain ranges, including Dedza Mountain
(2198m, 7209ft) separate this from the land around Lake Malawi at 500m (1600ft).
During the wet season, from mid November to mid April, rain
falls in heavy downpours, providing the annual rainfall of 800 to
1200mm - about the same as England gets over the whole year. There
is hardly any rain in the other seasons. The temperature at this time
of year is equivalent to a warm English summer day but the sun is
more intense. In the cooler season night temperature in June and
July can fall to below 10°C.
