Best time to climb Kilimanjaro is a crucial factor for anyone planning to conquer Africa’s highest peak. Rising 5,895 meters (19,341 feet) above sea level, Mount Kilimanjaro is a bucket-list destination for trekkers worldwide. Unlike many other high-altitude climbs, Kilimanjaro requires no technical mountaineering skills, making it accessible to both novice and experienced hikers. However, selecting the right season is essential for a safe, enjoyable, and successful climb.
Best time to climb Kilimanjaro depends largely on the mountain’s weather patterns, which vary throughout the year. The most favorable conditions occur during the dry seasons—January to March and June to October—when trekkers can enjoy clear skies, moderate temperatures, and higher summit success rates. The rainy seasons—April to May and November to early December—bring heavy rainfall, slippery trails, and reduced visibility, making the climb more challenging. While some experienced hikers choose the off-season to avoid crowds, most climbers prefer the dry months for a more comfortable trekking experience.
Best time to climb Kilimanjaro also influences the breathtaking scenery and overall trekking experience. As climbers ascend through Kilimanjaro’s five ecological zones, they encounter diverse landscapes, from tropical rainforests to icy glaciers. Choosing the right time ensures manageable trail conditions and maximizes the chances of witnessing stunning sunrise views from the summit. By understanding the seasonal variations and planning accordingly, trekkers can significantly improve their chances of reaching Uhuru Peak and making the most of their adventure on the Roof of Africa.
Bushland Zone (800-1,800m)
The Bushland Zone is the first area trekkers encounter as they begin their climb. Situated between 800 and 1,800 meters, this zone is characterized by a warm, lush environment with rich vegetation. The temperatures here remain mild, often ranging from 20°C to 30°C (68°F to 86°F). This lower altitude zone is home to tropical plants, savannahs, and some wildlife like monkeys and birds. Although the weather is generally pleasant, it can be humid, especially in the early mornings and late afternoons.
Rainforest Zone (1,800-3,000m)
As trekkers move higher, they enter the Rainforest Zone, which spans from 1,800 to 3,000 meters. This zone is marked by high humidity, frequent rainfall, and a dense canopy of trees. Climbers will feel the drop in temperature, which generally ranges from 15°C to 20°C (59°F to 68°F). The rainforests offer beautiful views, but the trail can become slippery due to the constant moisture. The humidity here can be stifling, and climbers may experience fog and mist as they trek through this wet, atmospheric region.
Moorland Zone (3,000-4,000m)
The Moorland Zone, located between 3,000 and 4,000 meters, marks the transition to cooler temperatures. The climate in this zone is much drier, and trekkers will notice the air becoming thinner as they ascend. The temperature typically drops to around 5°C to 15°C (41°F to 59°F), with occasional mist and light rainfall. Vegetation begins to thin out, and the landscape becomes more barren, dominated by heathers and grasses. While the weather is cooler and more comfortable for hiking, the occasional mist and low cloud cover can make visibility challenging at times.
Alpine Desert Zone (4,000-5,000m)
Above 4,000 meters, trekkers enter the Alpine Desert Zone, where the environment becomes starkly different. This zone is dry, with little vegetation, and is characterized by extreme temperature shifts. During the day, temperatures can soar to 20°C (68°F), but they plummet drastically at night, sometimes dipping below -5°C (23°F). The wind can be intense and the air is noticeably thinner, making it more difficult to breathe. This zone requires extra preparation, as dehydration and altitude sickness can become concerns.
Arctic Zone (5,000m+)
The Arctic Zone, located above 5,000 meters, is the highest and most extreme part of the climb. Here, temperatures regularly fall below freezing, and trekkers can expect glacial conditions with strong winds and snow. The air is thin, containing less oxygen, which makes breathing more difficult and increases the risk of altitude sickness. This zone is incredibly challenging due to the harsh conditions, and climbers will need specialized gear to deal with the cold and high altitude.

Kilimanjaro’s climate is influenced by two distinct seasons: the dry season and the wet season.
The dry season, which runs from June to October and January to March, is generally the best time to climb Kilimanjaro. During this period, trekkers experience clear skies, dry trails, and stable weather conditions. The trails are firmer and less slippery, especially in the Rainforest Zone, making the trek smoother and safer. While the temperatures in higher zones are cooler during this time, the overall weather is more predictable, which increases summit success rates.
In contrast, the wet season—April to May (long rains) and November to early December (short rains)—brings heavy rainfall that can make trails slippery and difficult. The Rainforest Zone becomes particularly challenging during these months due to the high humidity and frequent downpours, which can lower visibility and increase the risk of injury. The Moorland and Alpine Desert Zones also experience more rain, which can make the higher elevations colder and more dangerous. While some climbers still attempt the trek during the rainy months, it is generally not recommended unless you’re an experienced trekker prepared for the harsh conditions.
A. January to March (Dry Season – Fewer Crowds, Colder Summit)
Pros:
The period from January to March offers some of the clearest skies you’ll experience on Kilimanjaro, with breathtaking views throughout the climb. The dry conditions during these months also provide ideal trekking conditions for most of the ascent, especially in the lower altitudes. At higher altitudes, there may be occasional snowfall, adding to the mountain’s dramatic beauty. Another key advantage is the fewer trekkers, meaning the trails are less crowded, giving climbers a more peaceful, personal experience.
Cons:
One downside to climbing during this period is the colder summit conditions. As temperatures can drop significantly, reaching freezing or below, trekkers must be well-prepared with proper cold-weather gear, including warm clothing and sleeping bags. Additionally, although rainfall is less frequent compared to other seasons, there is still a slightly higher chance of precipitation than in the dry months of June to October, especially in the rainforest and moorland zones.
Best for:
This season is ideal for trekkers who prefer solitude and are capable of handling cold conditions. Those looking for a quieter experience, without the heavy crowds found during the peak season, will appreciate the relative peace and serenity of climbing in January to March.
B. June to October (Peak Season – Best Weather, Most Crowded)
Pros:
The June to October window is regarded as the peak season for climbing Kilimanjaro due to its most stable weather conditions. These months typically offer dry, sunny skies with excellent visibility across the mountain, making it the perfect time to enjoy the stunning views of the landscapes and surrounding wildlife. The dry trails and moderate temperatures enhance comfort while trekking, contributing to the high success rates seen during this period.
Cons:
The downside to this season is that it is also the most crowded time on the mountain, particularly in July and August. With more trekkers, there can be longer queues, more crowded campsites, and less solitude on the trails. Additionally, the increased demand during these months leads to higher costs for accommodation, gear rental, and permits.
Best for:
This season is perfect for trekkers who prioritize stable weather conditions and don’t mind the crowds. Those who are focused on summit success and the best weather, and are willing to pay a bit more for a guaranteed clear and stable climate, will find this period ideal.
A. April to May (Long Rains – Wet and Muddy Trails)
Cons:
The April to May period corresponds to the long rains season on Kilimanjaro, characterized by heavy rainfall and challenging trekking conditions. During this time, the trails become muddy and slippery, especially in the Rainforest and Moorland Zones, making the climb more difficult and dangerous. The constant rain reduces visibility, and the wet conditions significantly increase the risk of hypothermia for those who are unprepared. The heavy moisture also creates boggy, unstable terrain, adding to the overall difficulty of the trek. Due to these conditions, the success rates for summit attempts are notably lower, especially for those who are not accustomed to such harsh environments.
Who Might Consider This?
This season is only suitable for highly experienced trekkers who thrive on challenges and are prepared for the risks that come with difficult, wet conditions. These trekkers must be equipped with the right gear and have the stamina to handle slippery trails, extended rain, and potential altitude sickness in less-than-ideal weather. For most people, this season is better avoided unless they are seasoned and well-prepared for extreme conditions.
B. November to Early December (Short Rains – Less Crowded, But Unpredictable)
Cons:
The short rains season from November to early December brings unpredictable weather, with some days being clear and sunny while others are rainy and cloudy. While there is less rain than during the long rains, it can still cause lower visibility and occasionally lead to trail washouts, particularly in the Rainforest Zone. The trail conditions can become challenging, with sections of the path becoming slippery and muddy, especially after a heavy downpour. Visibility is compromised at times, which can diminish the overall trekking experience. Additionally, the weather is less stable than in the dry months, making it a riskier option for those unprepared for rapid weather changes.
Who Might Consider This?
This period may appeal to trekkers seeking a quieter climb, as there are fewer climbers compared to the peak season. However, these trekkers must be willing to take on the weather risks and adapt to the changing conditions. Those who are flexible and comfortable with some unpredictability in terms of weather and trail conditions may find the short rains season an option, but it is not ideal for those prioritizing stability and summit success.
A. Full Moon Climbs
Benefits of Climbing Under a Full Moon:
One unique aspect of climbing Kilimanjaro is the opportunity to trek under a full moon. This can significantly enhance the experience, especially on summit night. A full moon illuminates the trail, making the night trek easier and more magical, providing stunning views of the mountain’s glaciers and the crater. The moonlight offers natural visibility, reducing the reliance on headlamps and creating an unforgettable atmosphere. As you approach the summit, the view of the moonlit glaciers and Kilimanjaro’s icy crown is truly breathtaking.
Best Months for Full Moon Climbs:
The exact dates of the full moon vary each year, but it typically occurs once a month. For trekkers wishing to plan their climb around the full moon, they should research the lunar calendar for their specific year of travel. Full moon climbs are popular among those seeking a unique and memorable trekking experience, making it an attractive option for climbers who want an added challenge and beauty on their ascent.
B. Acclimatization and Fitness
Importance of Gradual Acclimatization:
When climbing Kilimanjaro, proper acclimatization is crucial to avoid altitude sickness. The mountain’s elevation gains steadily, and without allowing time for the body to adjust, trekkers may experience symptoms such as dizziness, nausea, and headaches. To mitigate the risks, it’s essential to choose a route that provides adequate acclimatization time and to ascend at a steady pace. Opting for longer routes with slower ascents like Lemosho or Machame will allow your body time to adapt to the changing altitude, reducing the likelihood of altitude-related issues.
Choosing the Right Route and Pace:
Your fitness level and experience should determine your chosen route and pace. For beginners or those less accustomed to high altitudes, routes with more gradual elevation gains and longer acclimatization periods are preferable. More experienced trekkers may opt for quicker ascents, but should still ensure they’re physically prepared for the mountain’s demands. Proper training leading up to the climb, focusing on cardiovascular fitness and strength, can help ensure a smoother climb and higher chances of summit success.
C. Budget and Availability
High Season (June-October, January-March):
Climbing Kilimanjaro during the high season means better weather, clearer skies, and an increased chance of a successful summit. However, this comes with higher costs due to the demand for permits, accommodations, and services. Trekking during these peak months (particularly June-October and January-March) typically requires early booking to secure your spot. Many tour operators and accommodations raise their prices during the busy months, so it’s important to plan well in advance if you want to trek during this time.
Low Season (April-May, November-December):
The low season offers cheaper rates, with lower demand for trekking permits and accommodations. If you’re on a budget, climbing during the rainy months (April-May, November-December) can be a cost-effective option. However, the trade-off is that the weather can be unpredictable, with wet, slippery trails, lower visibility, and a higher likelihood of adverse conditions. For those seeking a quieter, more affordable experience and who are prepared for the challenges of trekking in wet conditions, this season can still offer a rewarding adventure.
To recap, the best months for climbing Kilimanjaro depend on your preferences for weather, crowd levels, and climbing conditions:
It’s generally best to avoid the rainy seasons (April-May and November-December) unless you’re an experienced trekker who is comfortable with unpredictable weather and challenging conditions.
Final Tips:
Plan your climb based on your weather preference, fitness level, and trekking experience. If you prefer better weather, June-October is ideal. If you’re looking for a quieter experience and can handle colder conditions, January-March might be the perfect choice.
Book with a reputable tour operator to ensure a well-organized and safe climb. Kilimanjaro is a challenging ascent, so having a professional guide and proper logistics is crucial for a successful summit.
