The Mount Kilimanjaro weather affects your climb and your success chances. When to climb Kilimanjaro is an important decision. Bad weather on Kilimanjaro not only makes for a miserable trek and ruins your photos, most importantly it simply makes the climb twice as hard! You are a lot more likely to reach the summit if the weather on Kilimanjaro is good. Mount Kilimanjaro is near the equator. In the tropics there is no such thing as summer and winter. There are only dry and rainy periods. Or “dry seasons” and “wet seasons”. Climbing Kilimanjaro during the wet season means you have to slog through very deep mud during the first days. At higher altitude you have fog and drizzle, and slowly but surely the moisture will creep into your clothes, your gear, your bones… At the top you may have to fight your way through ice and snow. Having moisture in your clothes and everything is not going to help with the cold up there. But there are other aspects to consider as well. The temperatures, the views, and of course the number of people on the mountain. As so often, there is no hard and fast answer and no single best time to climb Kilimanjaro. So lets look at the Kilimanjaro weather details over the year.
