Mount Kilimanjaro Climate
Due to Mount Kilimanjaro's proximity to the equator, this region does not experience the extremes of winter and summer weather, but rather dry and wet seasons. January and February are the warmest months, April and May are the wettest months, June and July are the coolest months, and August and September are the driest months. January, February, and September are considered to be the best months to climb Kilimanjaro in terms of weather.
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 Uruhu peak cross different ecological zones. Throughout the climb, temperatures vary considerably with the altitude and time of day. Mount Kilimanjaro has five major ecological zones, each approximately 3,280 feet (1,000 m) in altitude. Each zone is subject to a corresponding decrease in rainfall, temperature and life as the altitude increases. At the beginning of the climb, at the base of the mountain, the average temperature is around 70°F to 80°F (27°C to 32°C). From there, the temperatures will decrease as you move through Mount Kilimanjaro's ecological zones. At the summit, Uruhu Peak, the night time temperatures can range between 0°F to -15F (-18°C to -26°C). Due to Mount Kilimanjaro's great height, the mountain creates its own weather. It is extremely variable and impossible to predict. Therefore, regardless of when you climb, you should always be prepared for wet days and cold nights.
