A Comprehensive Guide to Expectations on Kilimanjaro Weather

A Comprehensive Guide to Expectations on Kilimanjaro Weather

Kilimanjaro’s weather can generally be categorized into ‘wet and dry’ months rather than seasons. This distinction arises because Mount Kilimanjaro, located in the tropics, is such a massive geographical feature that it effectively generates its own weather patterns.

Weather conditions and temperatures on Kilimanjaro exhibit significant variations between day and night, as well as with changes in altitude. Hikers must anticipate substantial fluctuations in temperature throughout the day and as they ascend higher. Hence, layering clothing becomes crucial (refer to our comprehensive guide on Kilimanjaro gear, especially clothing).

This article offers a convenient month-by-month overview of Kilimanjaro’s weather, along with detailed descriptions of historical weather trends for each of Kilimanjaro’s climatic zones. Additionally, you’ll find weekly forecasts and information on summit temperatures on Kilimanjaro.

Mt Kilimanjaro Weather by Month

What is the weather like on Kilimanjaro in January and February?

January and February mark the onset of the first “short dry season” on Mount Kilimanjaro, rendering it an ideal time for trekking. During this period, temperatures tend to be cooler compared to the longer dry season from June to September, increasing the likelihood of encountering snow on the upper slopes of Mount Kilimanjaro.

It’s important to note that during my last summit in February, the wind was exceptionally strong at the higher camps and escalated to gale force at Base Camp and up to Stella Point. These extreme winds led many trekkers to abort their summit attempts, as they also blew dust into their faces, causing irritation to the eyes. From my personal experience, I would recommend carrying a pair of safety goggles. While goggles are not typically included in any Kilimanjaro gear lists and there’s an 80% chance you won’t need them, having them can be a lifesaver if you encounter such conditions.

Moving on to March, it represents a transitional month in the trekking season on Kilimanjaro. Towards the end of March, there is a noticeable increase in moisture in the air, and the likelihood of encountering rain rises. Nonetheless, the slopes are generally quieter during this time, making early March an opportune period for hiking Kilimanjaro.

 

What are the weather conditions like on Kilimanjaro in April and May?

April and May typically mark the wettest period on Kilimanjaro, making it less than ideal for trekking. We advise against planning treks during these rainy months.

How about the weather on Kilimanjaro in June, July, August, and September? June, July, August, and September stand out as the busiest months on Mount Kilimanjaro, coinciding with the summer holidays in Europe and North America. It’s rare to encounter rain or snow during these months on Kilimanjaro. Given the increased activity on the slopes, it’s relatively easy to find tour companies offering open group tours, facilitating cost savings.

 

And what’s the weather like on Kilimanjaro in October, November, and December?

October presents an excellent window for trekking on Kilimanjaro as a shoulder month. Weather conditions are favorable, and the slopes are less crowded. November experiences a brief rainy spell on Kilimanjaro. For those trekking in November, we recommend considering the northern approach via Rongai, which tends to be drier. December tends to be cold, often accompanied by significant snowfall. Trekking remains feasible if you’re prepared for the cold. December on Kilimanjaro has gained popularity for Christmas or New Year summit attempts.

Mount Kilimanjaro Temperature

The temperature on Kilimanjaro undergoes significant changes with altitude, leading to distinct climatic zones on the mountain, each characterized by its unique flora and fauna.

Below, we provide a brief overview of Kilimanjaro’s temperature as you ascend through different altitudes.

Rainforest Zone (Approximately 800 meters to 3,000 meters)

As you embark on your trek, you’ll enter the tropical rainforest zone, characterized by high humidity and occasional light mist or drizzle. This area of Kilimanjaro is adorned with diverse flora, including orchids, ferns, fig trees, and olive trees. It’s common to encounter Blue and Colobus monkeys, and trekkers following routes such as the North-East Rongai, Western Lemosho, Shira, or Northern Circuit may even catch glimpses of elephants, buffaloes, and large antelopes.

Low Alpine Zone (Approximately 3,000 meters to 4,200 meters)

Around 3,000 meters, the rainforest transforms swiftly into semi-arid grasslands and moorlands, forming what is known as the low alpine zone. Here, heather and small shrubs dominate the landscape, with notably lower humidity levels and evening temperatures dropping to sub-zero. Senecios and Giant Lobelias, resembling distorted palm trees, stand out as the prominent flora in this zone. While wildlife is sparse, it’s common to spot crows scavenging for food overhead.

High Alpine Zone (Approximately 4,200 meters to 5,000 meters)

This zone presents an arid desert landscape that is notably harsh. Daytime temperatures soar, accompanied by intense solar radiation (be sure to apply ample sun cream). As night falls, temperatures plummet to below freezing. From this vantage point, the slopes of Kibo and the summit of Kilimanjaro come into clear and perfect view.

Glacial Zone (Approximately 5,000 meters to 5,895 meters)

The ultimate zone encompasses the upper reaches of Kibo and Mawenzi, characterized by high-altitude arctic conditions. Life in this zone is exceedingly scarce due to oxygen levels being nearly half of what they were at lower elevations of the mountain. The slopes leading up to Kilimanjaro’s summit are coated with fine glacial silt, while large glaciers are visible from the crater rim. Given the combination of high solar radiation during the day, freezing temperatures at night, gale-force winds, and diminished oxygen levels, lingering in this zone is ill-advised.

Snow on Kilimanjaro

Snowfall on Kilimanjaro can occur throughout the year, although it is most prevalent from November to March. Below is a chart illustrating average snowfall by month.

Understanding Mount Kilimanjaro’s Weather

To grasp Kilimanjaro’s weather intricacies, it’s essential to delve into the prevailing trade and anti-trade winds traversing the area.

Why?

Because these winds transport moisture from the ocean. Upon encountering substantial barriers such as mountains, they ascend, cool, and condense, resulting in the formation of clouds and precipitation, including rain and snow.

The primary drivers of weather phenomena on Mount Kilimanjaro are the South-east trade winds and North-east anti-trade winds. Below, we elaborate on the impact of each wind.

Mount Kilimanjaro Weather FAQ

What is the temperature like at the summit of Mount Kilimanjaro?

Temperatures at the summit of Mount Kilimanjaro typically range from 0 to -20 degrees Celsius (32 to -4 degrees Fahrenheit). The wind plays a significant role in determining the temperature at the summit. Wind chill can make a seemingly cold night, such as -2 degrees Celsius (28 degrees Fahrenheit), feel as frigid as -15 degrees Celsius (5 degrees Fahrenheit). It’s noteworthy that temperatures are coldest at night, coinciding with the time when most trekkers aim for the summit. However, by late morning, the summit can feel quite warm, particularly on clear, windless days.

Which months experience the most rainfall on Kilimanjaro?

The wettest months on Kilimanjaro are April and May, which are generally unfavorable for hiking the mountain. Late March also sees considerable rainfall. Additionally, there is a brief rainy season in November. However, the northern side of Kilimanjaro lies in a rain shadow, so if you’re constrained to these months, consider opting for the Rongai route.
