How Weather Affects Kilimanjaro Climbs
Kilimanjaro’s unique location near the equator means that it doesn’t experience the traditional four seasons seen in other parts of the world. Instead, the weather on Kilimanjaro is influenced by the alternation between wet and dry seasons. These seasonal variations greatly impact the climbing conditions, trail difficulty, and visibility.
- Rainy Seasons: Kilimanjaro experiences two main rainy periods – the long rains from March to May and the short rains from November to December.
- Dry Seasons: The best climbing conditions are during the dry seasons, which run from June to October and January to February.
Planning your climb during the dry season is highly recommended, as the trails are less slippery, and there are fewer risks of weather-related delays. For more details on the best months to climb, check this resource.
Temperature Variations on Kilimanjaro
As you ascend Kilimanjaro, you will pass through five distinct climate zones, each with varying temperatures:
- Cultivation Zone (800m – 1,800m): This area at the base of Kilimanjaro is warm, with temperatures averaging between 25°C to 30°C (77°F to 86°F). The weather is generally mild, but occasional rain showers are common.
- Rainforest Zone (1,800m – 2,800m): Temperatures cool down as you move into the rainforest, where you can expect humid conditions with frequent rain, especially during the wet seasons. Daytime temperatures are around 15°C to 20°C (59°F to 68°F).
- Heath/Moorland Zone (2,800m – 4,000m): Here, the air becomes drier and cooler, with daytime temperatures ranging from 5°C to 15°C (41°F to 59°F). Night temperatures can drop to freezing.
- Alpine Desert Zone (4,000m – 5,000m): This area is characterized by extreme temperature fluctuations, where daytime highs can reach 25°C (77°F), but at night, temperatures can drop well below freezing.
- Arctic Zone (5,000m – 5,895m): The summit zone is cold and windy. Daytime temperatures rarely rise above freezing, and nighttime temperatures can plummet to -20°C (-4°F) or lower.
