The weather on Mount Kilimanjaro varies widely from the cultivated zone at the base, the rainforest at the foot slopes of the mountain, to the arctic zone at the summit. The temperatures can range from 25⁰C at the base of Mount Kilimanjaro to subzero by the time you reach the summit. As you traverse different vegetation zones on your route, expect some rainfall too in the process of trekking. Due to the high altitudes of Mount Kilimanjaro, the mountain creates its own weather.

Best Seasons (Weather-Wise)
- Best overall — June to October (dry season, clearer skies, fewer rains)
- Good secondary — December to February (also dry, warmer at lower levels)
- Shoulder seasons — November and March (variable, can still be good)
- Avoid if possible — April–May (long rains) and late November (short rains) — trails can be very muddy and slippery
What to Expect on Summit Night
- Starts around midnight in complete darkness.
- Temperatures often drop to -10°C to -25°C (14°F to -13°F) with wind chill.
- Strong winds are common near the crater rim.
- Snow and ice possible on the summit (especially after recent rains).
Daily Weather Patterns
- Mornings are usually clear and sunny.
- Clouds often build in the afternoon (especially in the forest and moorland zones).
- Rain showers are common in the lower zones.
- Above 4,000 m it is much drier and colder.
Practical Tips
- Layering is essential — You can experience all four seasons in one day.
- Sun protection — UV is very strong at altitude — wear sunscreen and sunglasses.
- Rain gear — Always carry a waterproof jacket and pants in your daypack.
- Warm layers — Down jacket and warm hat/gloves are critical for summit night.
The dramatic weather changes are part of what makes Kilimanjaro so special — you go from tropical rainforest to arctic conditions in less than a week.
