Kilimanjaro Best Time to Climb and Altitude Sickness: A Practical Guide
The driest months give the clearest weather, while a slow pace gives your body time to adapt.
Kilimanjaro can be climbed all year, but the most popular windows are January to March and June to October, when rain is lighter. April, May and November are wetter, with fewer climbers and cloud cover on the lower slopes.
Altitude sickness is the main risk. Symptoms include headache, nausea and fatigue, and they can progress. Climbing slowly, staying hydrated and descending if symptoms worsen are the basic rules. Read the routes comparison to plan a gradual ascent.
This guide is part of our East Africa travel guides. When you are ready to plan, see our Uganda safari packages or the Ameera Africa Safaris Uganda tours homepage.

Seasons on the Mountain
Mornings are usually clear, with cloud building later. Temperatures fall sharply at night, so layers and a warm sleeping bag are essential.
Preventing Altitude Sickness
Choose a longer route, walk slowly, drink water, avoid alcohol and tell guides about symptoms. Medication may help, so speak to your doctor before travelling.
Packing and Preparation
Break in boots, train with long hikes and bring good-quality gear. See the main guide for packing lists, and the best time to visit Tanzania for safari timing.
