You can climb Mount Kilimanjaro throughout the year but the best seasons to climb are January to March and June to October.
January to mid-March is the best time to climb Mount Kilimanjaro; the weather is warm and the skies are clear in the morning and in the evening. January and February are the warmest months on Kilimanjaro.
June to October is also a popular season because it coincides with the American and European summer holidays. The months of June and July are cold but you will not encounter much rain on the mountain. August, September, and October are the driest months on the Mount Kilimanjaro.
April, May, and November are the wettest months on Mount Kilimanjaro; they are not ideal for hiking up the mountain. If you plan to climb Kilimanjaro during these wet months, pack enough warm clothes and good rain gear.
