As demonstrated, the warmest months are January and February, the wettest months are April and May, the coolest months are June and July, and the driest months are August and September. These generalizations about Moshi’s weather also apply to Mount Kilimanjaro.
Mount Kilimanjaro does not see significant temperature fluctuations from season to season due to its proximity to the equator. Instead, the height and time of day play a larger role in determining the temperature on Mount Kilimanjaro. The typical temperature at the start of the ascent, at the base of the mountain, is roughly 70 to 80 degrees Fahrenheit (21 to 27 degrees Celsius). As you progress through Mount Kilimanjaro’s ecological zones, the temperature will drop.
Temperatures at the top, Uhuru Point, can drop to 20 to -20 degrees Fahrenheit during night (-7 to -29 degrees Celsius). Mount Kilimanjaro develops its own weather due to its immense height. It is highly unpredictable and impossible to forecast. As a result, you should always be prepared for wet days and cold nights, regardless of when you climb.
