APRIL – MAY
The rainy season starts at the end of March and continues until the middle of May. April marks the beginning of the coldest time of the year in Tanzania. These months are so dank and drizzle that some operators simply do not offer climbs in April/May at all.
JUNE – JULY
The frequency of rain gradually decreases. The weather on Kilimanjaro is fairly dry and clear but the nights are still bitter cold. June is usually quiet, sunny, and, in our opinion, much underrated in terms of climbing. It is an excellent idea to choose June for your adventure because of great weather and almost climbers-free routes.The number of climbers will be increasing as the year progresses. Starting from July the majority of the routes will be quite busy.
AUGUST – OCTOBER
The peak climbing season on Kilimanjaro is on August-September. The weather is particularly good for climbing: the days are clear and somewhat warmer than in June/July. At the same time it may be cloudy in the forest/moorland zone, as well as it may be rainy on the southern routes (Machame and Umbwe). However, once you leave the rain forest behind it will be sunny.
good weather conditions last into mid-October and the number of climbers drops dramatically, giving you a good chance to enjoy Kilimanjaro treks almost alone. At the end of October, the weather becomes more changeable. As long as you are equipped to withstand the occasional shower, this should not present any major challenges.
November is the “small” rainy season. The rainy weather may last into mid-December. The temperatures have dropped and the moisture mist covers the Mount, making your climb more tricky and risky, yet more challenging and exciting. November might not be the best pick in terms of weather, but gives a great opportunity to enjoy the breathtaking views of misty-covered Mount with its snow-capped peak, and to make some terrific pictures.
DECEMBER – JANUARY
Christmas and New Year are the second peak climbing season on Kilimanjaro. The climbers traffic is extremely high, although there is a high chance of raining and thick clouding in the lower altitudes of Kilimanjaro.
JANUARY – MARCH
Mid-January to mid-March are very popular among climbers. The weather is perfectly balanced: it is neither too cold, nor too wet. The days are generally dry, though occasional rains may happen. The possibility of rain increases in the second half of March.
