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

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.
