Kilimanjaro weather

The temperatures on Mount Kilimanjaro range from hot to bitter cold. The journey from the Gate to the peak is like traveling from the equator to Antarctica in a matter of days. This is because the routes to the Uhuru peak cross different ecological zones. Mount Kilimanjaro has five major ecological zones, each approximately 3,280 feet (1,000 m) in altitude and each zone is subject to a corresponding decrease in rainfall, temperature and life as the altitude increases. 

Due to its proximity to the equator, Mount Kilimanjaro does not experience wide temperature changes from season to season. Instead, the temperatures on Mount Kilimanjaro are determined more so by the altitude and time of day. At the beginning of the climb, at the base of the mountain, the average temperature is around 70 to 80 degrees Fahrenheit (21 to 27 degrees Celsius). From there, the temperatures will decrease as you move through Mount Kilimanjaro's ecological zones. At the summit, Uhuru Point, the night time temperatures can range between 0 and -15 degrees Fahrenheit (-18 to -26 degrees Celsius). Due to Mount Kilimanjaro's great height, the mountain creates its own weather. It is extremely variable and impossible to predict. Therefore wet days and very cold nights can be expected.
