The weather on Mount Kilimanjaro can vary from very hot to extremely cold within the same day although it does not experience wide temperature changes from season to season. Instead, the temperatures on Mount Kilimanjaro are determined more by the altitude and time of day. At the base of the mountain, the average temperature is around 21 to 27 °C. At the summit, Uhuru Point, the night time temperatures can range between 0 and -30 °C.
Like all great mountains, Kilimanjaro creates its own weather which can be extremely variable and difficult to predict. Climbers should be prepared for this variability with plenty of warm clothes and good waterproofs.
