The best time to hike Kilimanjaro is largely defined by the mountain's rainfall patterns. While technically accessible year-round, certain periods offer much more favorable conditions for reaching the summit.
Dry Season (June-October)
The dry seasons are widely considered the best seasons for a Kilimanjaro expedition. These periods offer the most stable weather the mountain sees, with less rainfall, clearer skies, and improved visibility. This means safer trails, more comfortable temperatures, and a higher chance of enjoying panoramic views from the summit.
However, the dry seasons also come with peak season crowds. You can expect more climbers on the trails (especially during July and August) and higher prices for accommodation and guiding fees due to increased demand.
It’s also worth noting that during this period the weather can become quite warm on the mountain. February is generally the hottest month. While this might sound appealing, it's important to remember that intense sun and heat can lead to dehydration and sunburn, especially at higher altitudes. Climbers should take extra precautions during this time, including increased water intake, proper sun protection, and acclimatisation.
Wet Season (April-May and November-December)
Kilimanjaro has two distinct wet seasons — April to May (where the mountain sees heavy rainfall and snowstorms) and November to December (where it rains heavily but for shorter periods). This heavy rainfall can lead to muddy trails, reduced visibility, and potentially hazardous hiking conditions.
While the wet season can mean a more challenging and less pleasant climb, it also means fewer crowds and potentially lower prices. Plus, during the rainy season, the rainforest is particularly lush, which is another bonus to trekking during this period.
