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.
