Mount Kilimanjaro has unique weather conditions that change throughout the year and across different altitude zones. Because the mountain rises to 5,895 meters, climbers pass through several climate zones ranging from tropical rainforest to arctic summit conditions.
Understanding the weather by month helps climbers choose the best time to climb and prepare for the different conditions they will face during the trek. For a complete overview of the mountain and climbing routes, read the Kilimanjaro Climbing Guide.
