Best Time to Climb
Kilimanjaro has two dry windows and two rainy ones. Climb in a dry window and you get clear skies and firm trails; climb in a rainy one and you get mud, poor visibility, and a harder trip for no good reason.
January to mid-March: Warm days, cold nights, dry and clear, with daytime temperatures around 25°C to 30°C (77°F to 86°F) at the lower elevations. Quieter than the June-October window, a good choice if you'd rather share the trail with fewer people.
June to October (late June to early October is the sweet spot): The second dry season, warm days and colder nights at the lower elevations, and the most popular window overall; it lines up with the northern hemisphere's summer holidays, so expect more company on the trail, especially in July and August.
April to May: The "long rains," with mild temperatures around 15°C to 25°C (59°F to 77°F). Trails turn slippery and muddy and visibility drops. Avoid this window if you can.
November: The "short rains," similar temperatures to April and May but lighter and less predictable rainfall. December often dries out again and is climbable.
These are averages, not guarantees. Mountain weather is unpredictable everywhere, and Kilimanjaro is no exception, come prepared for rain and cold regardless of when you climb.
Temperature by Zone
The real driver of Kilimanjaro's weather isn't the calendar, it's altitude. You'll pass through five distinct climate zones between the gate and the summit, each colder than the last.
01Base: Moshi & Arusha
Warm and stable, 15°C to 28°C (59°F to 82°F). This is where your trip starts and ends, T-shirt weather most of the year.
02Rainforest Zone
Mild and humid, 12°C to 15°C (53°F to 59°F). Expect green canopy overhead and a good chance of rain regardless of season.
03Moorland Zone
Cool, 5°C to 10°C (41°F to 50°F). Vegetation thins out fast here, and the gap between day and night temperatures grows wider.
04Alpine Desert Zone
Cold, 0°C to 5°C (32°F to 41°F). Barren, rocky, and exposed, with strong sun during the day and a hard drop once it sets.
05Summit: Uhuru Peak
Extremely cold, -7°C to -29°C (19°F to -20°F). This is night-ascent territory, dress like it.
