Kilimanjaro Weather in December: Early vs. Late Month

Below is the definitive breakdown of the weather in Kilimanjaro in December across the month’s two distinct halves:
 
Time Period
Rainfall & Trail Conditions
Crowd Levels
Summit Conditions
Early December (1st – 15th)
Lingering short rains. Lower rainforest zones are muddy, wet, and steamy. Afternoon showers are common.
Seasonal low. Very quiet trails and campsites.
Cold, with potential for fresh snowfall. Views may be hazy if snow is actively falling.
Late December (16th – 31st)
Transition to the short dry season. Skies clear up dramatically, offering sunny, crisp views and dry trails.
Peak holiday demand. High volume of climbers around Christmas and New Year.
Bitterly cold. Temperatures plunge between -10°C and -20°C (14°F to -4°F), often with fresh, scenic snow.
Note on Kilimanjaro Temperature in December: While daytime temperatures at the base (1,800m) are warm and pleasant, averaging 15°C to 20°C (59°F to 68°F), the summit (5,895m) remains bitterly cold year-round. On summit night, expect temperatures to plummet to -15°C to -20°C (5°F to -4°F), with strong windchills making it feel even colder.
 
 

What is the Best Route Up Kilimanjaro in December?

If you are wondering what is the best route up Kilimanjaro in december, your choice should be dictated by your tolerance for rain and your need for acclimatization.
 
  1. The Rongai Route (The Driest Option): This is the absolute best route for an early December trek. It approaches the mountain from the north, near the Kenyan border, sitting in the mountain’s “rain shadow.” It receives significantly less precipitation than the southern routes, keeping the trails much more manageable.
  2. The Marangu route (The Hut Advantage): If you want to avoid sleeping in a damp, freezing tent during an early-December rainstorm, Marangu is your best alternative. It is the only trail on the mountain that offers permanent, dormitory-style wooden hut accommodations with dining halls, providing a massive shelter and morale advantage during wet weather. (Note: Always book the 6-day Marangu itinerary to ensure proper acclimatization, as the 5-day version has a notoriously low success rate).
  3. The Lemosho or Northern Circuit (7–9+ Days): Great for gradual acclimatization, extended itineraries, and scenic diversity. The extra days significantly boost your chances of summit success, which is crucial when weather windows are tighter.
 
 

Pros and Cons of Hiking Kilimanjaro in December

Before you climb Kilimanjaro in December, weigh these factors to ensure it aligns with your goals:
 
The Pros:
  • Holiday Time Off: Late December allows you to use holiday time off efficiently, combining the trek with a post-climb safari or Zanzibar beach extension.
  • Lush Scenery & Fresh Snow: The lower slopes are vibrantly green from the rains, and the summit is frequently dusted with fresh, photogenic snow.
  • Fewer Crowds (Early Month): If you trek in the first two weeks of December, you will enjoy near-complete solitude on the trails.
 
The Cons:
  • Mud and Rain (Early Month): You must be prepared for slippery, muddy trails and afternoon showers in the lower zones.
  • Peak Pricing (Late Month): Christmas and New Year weeks see high demand, meaning tour operators charge premium rates and permits sell out months in advance.
  • Freezing Summit Temps: December is one of the colder months at the summit, requiring top-tier cold-weather gear.
 
 

Essential Gear for a December Kilimanjaro Climb

The equipment needed for climbing mt kilimanjaro in december must account for both wet lower elevations and freezing high altitudes:
  • Waterproof Outer Shell: A high-quality, breathable, fully waterproof Gore-Tex jacket and rain pants are non-negotiable for the rainforest zone.
  • Gaiters & Pack Covers: Waterproof gaiters keep deep mud out of your boots, while heavy-duty pack covers (or internal dry bags) protect your gear from afternoon downpours.
  • Extreme Cold Sleep System: A 4-season sleeping bag rated to at least -15°C (5°F), paired with an insulated sleeping pad (R-value 4.0+).
  • Summit Night Essentials: An 800-fill down jacket, thermal mittens, a thick warm beanie, and a balaclava to protect your face from freezing wind and snow.
 
 

The Critical Role of Expert Guidance

Navigating the mountain during a transitional weather month requires professional, safety-first logistics and elite weather monitoring.
 
For comprehensive pre-trip planning, understanding how the shifting December weather impacts your specific route choice, and selecting an itinerary that prioritizes your safety over a rigid schedule, consulting a trusted Mount Kilimanjaro Guide is the essential first step. They will help you avoid dangerous, fast-track itineraries and connect you with operators who provide high-quality, waterproof 4-season tents and dining shelters.
 
Furthermore, having an experienced kilimanjaro local guide is the most critical safety investment you can make on the mountain. A top-tier, Wilderness First Responder (WFR) certified guide intimately understands the mountain’s microclimates. They will monitor the barometric pressure, manage your layering system to prevent sweat-chill and hypothermia, and make the life-saving call to adjust the summit push if severe weather threatens your safety.
