Weather on Kilimanjaro

Kilimanjaro weather can swing from hot sunshine to freezing cold in a single day. Unlike most destinations, the mountain does not change dramatically from season to season. Instead, temperature is driven by altitude and time of day. Because it is big enough to create its own weather, you should be ready for sun, rain, wind, cold and even snow on the same climb.

Temperatures by altitude

At the base of the mountain the average temperature is a mild 21 to 27 C (70 to 80 F). As you ascend through the climate zones it falls steadily, until night-time temperatures at the summit, Uhuru Peak, range from about -7 C to -29 C (20 to -20 F). Layering is the key to staying comfortable; see our Kilimanjaro packing list.

Kilimanjaro's five climate zones

You pass through all five zones on a single climb, which is why kit has to cover every condition.
ZoneAltitudeConditions
Cultivation800 to 1,800 mWarm, temperate farmland with plentiful rain
Rainforest1,800 to 2,800 mWarm, humid and often misty; can be muddy
Heath and moorland2,800 to 4,000 mWarm days, cold nights, more exposed
Alpine desert4,000 to 5,000 mArid, strong sun by day, freezing at night
Arctic summit5,000 m and aboveIce, snow and bitter cold; around half of sea-level oxygen

Rainfall and snow

The long rains from March to May are driven by moist south-easterly winds off the Indian Ocean, soaking the southern slopes and dropping snow on the summit. The short rains around November come from a drier north-easterly and are lighter, falling mainly on the northern slopes.

Month by month

We schedule climbs around the two dry seasons, which carry the highest summit-success rates.
MonthsSeasonWhat to expectDo we climb?
January to FebruaryShort dry seasonGenerally a little warmer, with superb summit conditionsYes — a top window
March to MayLong rainsHeavy rain makes trails wet and slipperyNo climbs in this window
June to SeptemberLong dry seasonCool but excellent, with little chance of rainYes — a top window
October to DecemberShort rainsLess predictable conditionsGenerally avoided once the rains set in

How weather affects your climb

Because conditions change so quickly, the golden rule is to be prepared for everything at once: breathable layers for warm forest days, waterproofs for sudden showers, and serious insulation for the freezing summit push. The dry seasons offer the most stable weather and the highest summit-success rates, which is why we schedule climbs around them. Choosing a longer route also gives you more margin if a day of bad weather slows you down. For the full picture, read our guides to climbing Kilimanjaro and the best routes.

Worth knowing

A longer route is the cheapest insurance against bad weather. An extra day gives you room to absorb a slow, wet stage without losing your summit attempt.

Weather on summit night

Most climbers set off for the summit around midnight to reach Uhuru Peak at sunrise. It is bitterly cold, often with snow or ice underfoot, but the clearing dawn skies reveal vast views over Mawenzi and the plains below. You can learn more about the mountain’s protected environment via the Kilimanjaro National Park (UNESCO) listing.
