The primary factor is safety. As the risks associated with trekking Kilimanjaro increase significantly when the weather is foul. The effects of rain, snow, mud, and cold can be very strenuous on your body. Correspondingly, your chances of Kilimanjaro summit success also increase significantly with nice weather.
Standing at a whopping height of 5,149 m. above sea level, Kilimanjaro is certainly big enough to create its own weather systems. Besides the altitude, the biggest factor affecting the weather in mount Kilimanjaro is the interaction of trade winds.
Due to its close proximity to the equator, the trade winds (monsoons) that move across the ocean, drawing moisture upwards are likely to get interrupted by the mountain. As a result, the wind pushes up towards the summit, cooling down as it goes, bringing rain and snow. Therefore Kilimanjaro sees frequent rainfall sometimes without any drastic change in temperature.
Mt. Kilimanjaro experiences its driest months from June to October. During this time, strong anti-trade winds blow in from the northeast. These winds carry little to no moisture, thus compressing the South-east winds downwards. Consequently, the mountain is relatively free of precipitation and clouds, especially higher up. We recommend popular routes like the Machame Route or Lemosho Route for this period.
With the incoming dominant winds from the South-east, April and May are the wettest periods of Kilimanjaro. The winds pick up a great deal of moisture while traveling over the Indian Ocean. Later as the wind direction gets forced up the mountain, it gradually cools down, condenses, and turns into clouds and precipitation.
If you’re planning to trek mount Kilimanjaro during this period, then it is best to avoid the southern slopes. Because this side gets maximum rain during these months. Instead, it would be more wiser to take the Rongai route. As this trail leads up to the less frequent rainy northern side of Kilimanjaro.
The month of November marks the beginning of the Northeast monsoon period in Mt. Kilimanjaro. This period brings frequent light rains on the north side of Mt. Kilimanjaro.
You can trek mount Kilimanjaro all year-round. However taking all the aforementioned Mt Kilimanjaro Climate factors into account, the best time to climb Kilimanjaro can be separated into two distinct periods: January to March and June to October. As both these Kilimanjaro climbing seasons offer different benefits depending on what you’re looking for.
