Climbing Kilimanjaro in December means trekking during one of the mountain's most popular and rewarding windows. December marks the start of a short dry-ish spell that runs into early January, bringing clearer skies, striking summit views, and a festive Christmas-and-New-Year atmosphere on the trail. It is not a flawless weather month, but with the right route, operator, and preparation, December can deliver one of the finest climbs of the year.
Below is a complete, honest guide to what to expect from the weather, the pros and cons, the best routes, snow on the summit, and how to prepare so you reach Uhuru Peak safely.
December sits between Tanzania's "short rains" (roughly November) and the drier, warmer stretch that peaks in January and February. In practice, the first half of December can still see occasional afternoon showers, while the second half — especially from mid-to-late December — usually settles into clearer, more stable conditions.
Because Kilimanjaro rises through several distinct climate zones, the weather you experience changes dramatically with altitude. At the forested base, daytime temperatures are mild — often around 21–27°C (70–80°F). As you climb higher, it grows steadily colder. On summit night near Uhuru Peak (5,895 m / 19,341 ft), temperatures routinely fall well below freezing, sometimes to −15°C (5°F) or lower with wind chill. For the full elevation picture, see our guide to how high Kilimanjaro is in feet and meters.
Yes. December is one of the more likely months to see fresh snow on the upper mountain, and the summit's remaining glaciers and ice fields are often at their most photogenic. A dusting of snow across the crater rim at sunrise is one of the great rewards of a December climb.
That said, snow cover varies from year to year, and Kilimanjaro's famous glaciers have retreated significantly over recent decades. Fresh snowfall is seasonal and temporary rather than the permanent ice caps of the past. To understand what to expect underfoot and overhead, read our detailed guide on whether Kilimanjaro has snow.
From mid-December onward, skies tend to clear and rainfall eases, especially compared with the wetter months of November, April, and May. Clearer air means better visibility, dramatic sunrises, and a higher chance of unobstructed summit views stretching across the plains far below.
Christmas and New Year on Kilimanjaro have a special energy. Many climbers deliberately time their trek to celebrate the holidays on the mountain, and reaching the Roof of Africa over the festive season is a milestone that is hard to beat.
With less cloud and fresh snow up high, December offers some of the year's most spectacular scenery — glinting glaciers, crisp horizons, and clear night skies packed with stars on your way to the summit.
December is peak season, and the Christmas-to-New-Year window in particular draws large numbers of climbers. Popular routes and camps can feel crowded, and the best operators book up months in advance. If you want a quieter experience, aim for early December or choose a less-travelled route.
The transition out of the short rains is gradual. The first week or two of December can still bring rain and mud on the lower, forested slopes, so waterproof gear remains essential.
As a high-season month with festive demand, December often carries premium pricing, and space with reputable operators is limited. Booking early is strongly recommended.
In a wetter-leaning early December, routes that approach from the drier northern and western sides — and those with better hut or camp infrastructure — are worth prioritising. Good options include:
Whichever you choose, longer itineraries with an extra acclimatisation day dramatically improve your odds of summiting. Compare all options in our guide to the best Kilimanjaro routes.
Your guide team is the single biggest factor in a safe, successful climb. A quality operator provides experienced guides, proper high-altitude gear, good food, and strict safety protocols. See our advice on how to choose the best Kilimanjaro tour operator.
December demands warm, layered clothing plus fully waterproof outerwear and sturdy, broken-in boots. Summit night is bitterly cold, so an insulated jacket, quality sleeping bag, gloves, and a warm hat are essential. Our full Kilimanjaro gear and packing list covers everything to bring.
Altitude — not the cold — is the main reason climbers turn back. Walk slowly ("pole pole"), choose a longer itinerary, stay hydrated, and eat well. New climbers can absolutely succeed with the right preparation; read whether a beginner can summit Kilimanjaro and how hard it is to climb Kilimanjaro before you go.
December kicks off the warmer, drier high season that continues through January and February. If you would rather avoid the festive crowds while still enjoying good conditions, the warmest and driest months to climb Kilimanjaro guide compares the whole calendar so you can pick the window that suits you best.
Yes. December is one of the more popular months, especially from mid-month onward when skies clear and rainfall eases. It offers good summit views, likely fresh snow up high, and a festive holiday atmosphere. The main trade-offs are peak-season crowds over Christmas and New Year and the chance of early-month showers.
Expect mild temperatures at the base — around 21–27°C (70–80°F) — dropping steadily with altitude to well below freezing on summit night, often −15°C (5°F) or colder with wind chill. Early December can still see rain, while mid-to-late December is usually drier and clearer.
Yes, fresh snow is common on the upper mountain in December, and the summit is often at its most photogenic. Snow cover varies year to year, and the mountain's glaciers have retreated significantly over time, so conditions are never guaranteed.
The Christmas and New Year period is one of the busiest windows of the year. Camps and popular routes can feel crowded, and the best operators book out months ahead. Early December is generally quieter than the holiday peak.
Longer, well-acclimatised routes such as Lemosho and Machame are excellent choices. If you are concerned about early-month rain, the Rongai Route approaches from the drier northern side, and the Marangu Route offers sleeping huts instead of tents.
It is mild at the base but genuinely cold up high. Summit night temperatures commonly fall below −10°C to −15°C (14°F to 5°F), and wind chill can make it feel colder. Warm layers, an insulated jacket, and a quality sleeping bag are essential.
Many climbers love celebrating the holidays on the mountain, and summiting over Christmas or New Year is a memorable bucket-list achievement. Just book early, as the festive window is in high demand and prices are typically at their peak.
Pack warm, layered clothing, fully waterproof jacket and trousers, sturdy broken-in boots, an insulated summit jacket, warm gloves and hat, and a cold-rated sleeping bag. Our Kilimanjaro gear and packing list has the complete rundown.
Yes. Kilimanjaro is a non-technical trek, and fit beginners regularly summit with a reputable operator, a sensible pace, and good acclimatisation. Read can a beginner summit Kilimanjaro for a full breakdown of what to expect.
Climbing Kilimanjaro in December is a rewarding, festive, and scenic experience. With clearer skies from mid-month, likely snow on the summit, and the magic of celebrating the holidays on the Roof of Africa, it is easy to see why December is such a popular choice. Book early, choose a reputable operator and a well-acclimatised route, pack for cold and wet, and take it slow — and you will give yourself the best possible chance of standing on Uhuru Peak.
