Mount Kilimanjaro weather changes dramatically from scorching heat to freezing cold within a single day. This majestic African peak creates its own weather systems, making conditions unpredictable and challenging for climbers. Understanding Kilimanjaro’s weather patterns will help you prepare for your summit attempt and pack the right gear.
At the base of the mountain, the average temperature is around 21 to 27 °C and at the summit, Uhuru Peak, the night time temperatures can range between 20 and -20 degrees Fahrenheit (-7 to -29 degrees Celsius). Like all great mountains, Kilimanjaro creates its own weather which can be extremely variable and difficult to predict. Hikers need to be prepared for warm, sunny conditions, and rain, wind, cold, and even snow.
Even though the best time to climb Kilimanjaro coincides with the “dry” seasons, rain, and snow are possible at any time of the year. As you get higher up, the temperatures can vary dramatically, one moment you can be trekking in baking sunshine, the next you’ll be layering up against a bitter wind.
Standing at 19,341 ft above sea level, Kilimanjaro is big enough to create it’s own weather systems. Being on the equator means the trade winds (sometimes called ‘monsoons’) that move across the ocean, drawing moisture upwards are interrupted by the mountain. This causes the wind to push up towards the summit, cooling as it goes, bringing rain and snow.
The long rainy season between March and May is a result of the trade winds from the south-east. These southerly winds from the Indian Ocean are laden with moisture, bringing rain to the lower slopes and snow on the top of Mount Kilimanjaro summit. During this season, the southern slopes get the most rainfall.
The ‘short rains’ in November are from a dryer wind coming from the northeast. As it hasn’t traveled across an ocean, the rains are shorter and less intense than during the long rains. Most of the rainfall during this season falls on the more northerly slopes.
Mount Kilimanjaro doesn’t experience wide temperature changes from season to season due to it’s proximity to the equator, Instead, the temperatures on Mount Kilimanjaro are determined more so by the altitude and what time of day it is. At the base of Mount Kilimanjaro where the the climb starts, the average temperature is around 70 to 80 degrees Fahrenheit (21 to 27 degrees Celsius). From the base when you ascent, the temperatures will decrease as you go through mountain’s 5 ecological zones.
At the Summit of Kilimanjaro, Uhuru Peak, which lies in the arctic zone the night temperatures can range between 20 and -20 degrees Fahrenheit (-7 to -29 degrees Celsius). Therefore, we recommend that you should always be prepared for wet and cold nights so please bring the necessary gear at all times.

Mount Kilimanjaro doesn’t experience seasonal temperature variations like most mountains. Furthermore, altitude and time of day determine the temperatures you’ll encounter. Additionally, the mountain stands at 19,341 feet above sea level, tall enough to generate its own weather systems that interrupt trade winds from the Indian Ocean.
Base of the Mountain (Cultivation Zone)
Summit (Uhuru Peak)
Climbers experience five distinct climate zones as they ascend, each with unique weather patterns.
The fertile volcanic soil creates farmland around Kilimanjaro’s base. Specifically, this zone receives 20-70 inches of annual rainfall, creating temperate conditions perfect for agriculture. Therefore, you’ll pass through this area quickly on your way to the trailhead.
Dense tropical rainforest absorbs moisture from the mountain, forming underground streams. Consequently, expect warm, humid conditions with thick mists under the canopy. Moreover, cloud cover occurs frequently, and muddy trails challenge hikers during wet periods.
Tall grasses and giant heathers replace the dense forest. Subsequently, wind exposure increases significantly in this zone. However, daytime temperatures remain comfortable, but nighttime brings bitter cold. Nevertheless, rain occurs less frequently, making hiking more pleasant.
This arid environment supports only hardy plants. Meanwhile, wind speeds increase while rainfall drops to just 10 inches annually. In contrast, warm daytime temperatures contrast sharply with rapidly dropping evening temperatures. As a result, campers often sleep above the clouds, creating magical starlit nights.
The summit zone receives minimal rainfall – most precipitation falls as snow. Additionally, rocky outcrops, volcanic scree, and glaciers dominate this barren landscape. Furthermore, oxygen levels drop to 49% of sea level. Finally, blustery winds and sub-freezing nighttime temperatures create extreme conditions.

The best climbing conditions occur during this period. Specifically, temperatures stay cooler than the short dry season, but precipitation remains minimal. Consequently, clear skies and stable weather make this the most popular climbing season.
Trade winds from the northeast bring shorter, less intense rains. However, the timing varies more than the long wet season, making conditions unpredictable. Therefore, climbing becomes challenging once the rains begin.
Popular climbing months with warmer temperatures than the long dry season. Particularly, late January through February offers excellent conditions, though weather patterns can vary yearly.
Southeast trade winds from the Indian Ocean create heavy rainfall. As a result, tour operators typically don’t offer climbs during this season due to dangerous trail conditions.
Most climbers begin their summit attempt at midnight, facing bitter cold with snow or ice on the trail. Subsequently, the goal reaches Uhuru Peak at sunrise when skies often clear, revealing panoramic views of Mawenzi and the African plains below.
Furthermore, summit temperatures range from 20°F to -20°F (-7°C to -29°C) at night. Additionally, the extreme altitude creates harsh conditions with strong winds and intense solar radiation during the day.
The dry air at high altitude dehydrates climbers rapidly. Therefore, carry extra water and drink frequently, especially in the alpine and arctic zones.
Solar radiation intensifies significantly above 13,000 feet. Consequently, protect all exposed skin with high-quality sunscreen, even on cloudy days.
The long dry season (June-September) offers the most stable weather conditions. Similarly, the short dry season (January-February) provides warmer temperatures but less predictable conditions. However, avoid the wet seasons (March-May and October-December) when heavy rains create dangerous trail conditions.
Mount Kilimanjaro’s position on the equator and massive height create unique meteorological conditions. Specifically, trade winds carrying moisture from the Indian Ocean hit the mountain and rise toward the summit, cooling and creating precipitation. Therefore, this process generates the distinct wet and dry seasons that affect climbing conditions.
Moreover, the mountain’s weather changes occur rapidly and without warning. Consequently, climbers must prepare for sunny conditions, rain, wind, cold, and snow – sometimes all in the same day.
Kilimanjaro weather presents one of the greatest challenges for climbers attempting Africa’s highest peak. Furthermore, the dramatic temperature variations, unpredictable precipitation, and extreme conditions at altitude require careful preparation and proper gear selection. Therefore, understanding these weather patterns helps climbers choose the best climbing season and prepare adequately for their summit attempt.
Whether you climb during the dry season or brave the transitional months, Kilimanjaro’s weather will test your preparation and determination. However, with proper planning and respect for the mountain’s power to create its own weather systems, you’ll be ready to face whatever conditions await you on your journey to Uhuru Peak.
