In Tanzania, there are two wet seasons and two dry seasons. The "long rains" run from March through May and the "short rains" runs from November to mid-December. Outside these times is considered the dry season. It can still rain during the dry season but statistically, it is much drier. This makes January, February and June through to October the best time to climb the mountain.
When trekking on Kilimanjaro, temperatures on average falls 1°C for every 200m in altitude gained. At the summit of Kilimanjaro because of the lower air pressure, there is effectively half the oxygen than there is at sea level
It is possible to climb Mount Kilimanjaro at any time of year, however, some months can be a lot colder than others.The two trekking seasons considered to be the best time to climb Mount Kilimanjaro fall between the months of January-March and June-October. January-March is likely to be a colder time to climb, compared to June-October, meaning that there is a bigger chance of finding snow when you reach Kilimanjaro's summit. March, April, November and December are considered to be the wettest months in the Kilimanjaro Region.These months are not considered ideal for trekking.
Some people also feel that the time of the full moon is the best time to climb Kilimanjaro. This is because the moonlight helps illuminate the trails in the early hours of summit day, it also makes the mountain's glaciers and any snowfall glisten in the dark, giving it a magical feel. We include full moon departures on both of our Kilimanjaro treks.
