January–February and July–October (dry seasons with clearer weather); avoid March–May (long rains) and April specifically (heaviest rainfall); June and November are shoulder months with more variable weather.

Climb duration: Minimum 5 days (Marangu Route from Momella Gate) to 9 days (Northern Circuit)—longer itineraries significantly improve summit success rates through better acclimatisation.

Success rates: Vary dramatically by route and duration—5-day Marangu: 50–60%, 6-day Marangu: 70–75%, 7-day Machame: 70–85%, 8-day Lemosho: 85–90%, 9-day Northern Circuit: 90–95%.

Fascinating facts:

• Kilimanjaro’s glaciers have shrunk approximately 85% since early 20th century due to climate change
• The mountain formed through three distinct volcanic episodes spanning 750,000 years
• Hans Meyer (German geographer) and Yohani Kinyala Lauwo (local guide) completed the first recorded summit in 1889

Physical preparation: 3–6 months cardiovascular training recommended (hiking, running, cycling, stair climbing); practice with loaded backpack; altitude exposure beneficial but not essential; mental preparation equally important as physical fitness.
