What Is the Best Month to Climb Kilimanjaro? Weather and Seasonal Guide
Skip the mud and the whiteouts. Here are the dry seasons and the best weather windows for booking your Mount Kilimanjaro trek. When you climb matters a lot on Mount Kilimanjaro. Africa’s highest mountain sits close to the equator and makes a lot of its own weather. Climbing in the right month or the wrong one can be the difference between a happy summit and a cold, wet retreat through sleet, mud and thick cloud. The good news is that you can climb Kilimanjaro in any of the twelve months. The even better news is that two clear seasons give you a much better chance of reaching the top, better trails and the kind of summit-morning views that make all the effort worth it. At Kilisa Tours and Safari, we have guided climbers to Uhuru Peak in every month and every season. This guide is our honest, month-by-month take on what to expect, so you can pick your dates with confidence and give yourself the best chance of standing on the roof of Africa.
Understanding Kilimanjaro’s Climate Zones
Before we get to the calendar, it helps to know why the weather on Kilimanjaro changes so much, and why altitude makes everything more extreme.
On the way up you pass through five different zones: farmland, rainforest, heath and moorland, alpine desert and the arctic summit zone. Each one has its own weather, and things can change a lot in a single day. It can be warm and sunny in the forest, cold and cloudy on the moorland and close to a blizzard at the summit crater, all on the same afternoon.
Tanzania has two rainy seasons, and both reach the mountain: the long rains from March to May and the short rains from November to December. The long rains in particular bring lots of moisture, cloud and rain. The forest sections of the trail get slippery, and higher up it’s cold and icy. The two dry seasons, January through February and June through October, are when conditions are best for climbing.
One thing to know: even in the best months, summit night on Kilimanjaro is cold. Very cold. At Uhuru Peak it often drops to minus ten or fifteen degrees Celsius, and the wind makes it feel even colder. Good gear matters a lot whenever you climb. Our trekking equipment guide and packing guide cover everything you need.
The Two Best Seasons to Climb Kilimanjaro
Season One: January and February, the Hot Dry Season
January and February fall between the short rains and the long rains. You get a clear, warm and fairly dry spell that many experienced Kilimanjaro guides rate among the best months on the mountain. The skies above the forest are clear, the upper mountain is dry, and the days at the lower camps are warm and pleasant.
Summit success rates in January and February are high. The trails are in good shape, you can often see a long way on summit morning, and the mountain is usually less busy than in the July-to-October high season. That makes for a quieter, more personal climb.
There’s a bonus if you want to add a Great Migration safari: January and February are calving season in the southern Serengeti. Our calving season safari is a great time to watch the herds, so a climb-and-safari trip in these months works very well. Have a look at our 10-day and 11-day Kilimanjaro combine tours for ideas.
January and February at a glance:
- Very good trail conditions, dry and firm underfoot
- Clear skies and good views from the summit
- Warm days at the lower camps
- Fewer climbers than in high season
- Fits well with the calving season Migration safari
- Cold up high, so good layers are a must
Season Two: June through October, the Cool Dry Season (Peak Climbing Season)
This is Kilimanjaro’s main climbing season, and there’s a good reason for that. The long rains end in late May, and from June the weather is at its most steady and predictable. The skies are clear, there’s very little rain, the trails are dry and firm, and summit conditions are about as good as they get, though always cold.
July, August and September are the busiest months on the mountain. Lots of people climb, the trails are busier, and the popular camps can be lively in the evenings. If you like a sociable mountain, with stories over dinner and other climbers to cheer on, this is your season. If you’d rather have it quieter, think about June or October. The conditions are just as good, with fewer people on the trail.
These months also line up with the Mara River crossings of the Great Wildebeest Migration in the northern Serengeti. For many of our guests, a Kilimanjaro climb plus a Migration safari between July and October is the trip they’ve always wanted.
June to October at a glance:
- The best overall weather of the year
- Dry trails on every route and at every height
- Very good summit views, with some of the clearest days of the year
- Among the highest summit success rates of the year
- Busiest from July through September, so book well ahead
- June and October have the same conditions with fewer climbers
- Fits well with the Mara River crossing Migration safari
Month-by-Month Climbing Guide
January ★★★★★
One of the best months on the mountain. Clear skies, dry trails and warm days at the lower camps. The view from the summit is often very good. There are fewer climbers than in high season, and hotels are better value. A great choice if you want top conditions without the July-to-September crowds. Pairs well with a calving season safari afterwards.
February ★★★★★
Just as good as January, and maybe the best single month to climb if you want great conditions and a quieter mountain. It’s warm, clear and dry over most of the mountain. Many first-time climbers don’t know about February, but experienced Kilimanjaro climbers do. We recommend it highly.
March ★★★☆☆
The long rains start in March, usually light at first and heavier as the month goes on. Early March can still be good, but by mid-to-late March the forest section gets really muddy and higher up there’s more cloud and rain. It’s doable for experienced trekkers with the right gear, but success rates start to drop. It’s not our first choice.
April ★★☆☆☆
The middle of the long rains. In April it rains a lot, and often, all over the mountain. The forest trails are very muddy, the upper zones are cold and often icy, and you often can’t see much from the summit. Some operators close their camps at this time. We don’t recommend April if reaching the summit is what matters most to you. That said, if budget comes first and you’re an experienced, flexible trekker, the much lower prices and nearly empty trails do have their appeal.
May ★★☆☆☆
Much like April, though things usually start to improve toward the end of May as the long rains ease off. Early May is still wet. Late May can bring some surprisingly clear spells. It’s still not a good choice for first-time Kilimanjaro climbers, and success rates stay lower than in the dry seasons.
June ★★★★☆
The dry season arrives and the mountain changes. June is the start of very good conditions: the trails are drying out after the rains, the skies are clearing, and the mountain is much quieter than in July and August. The lower slopes are pleasant, but June nights up high are noticeably colder than in January and February. A great choice if you want good conditions without the high-season crowds.
July ★★★★★
High season starts properly. July has very good conditions on every route: dry and clear, with good light up high. The popular camps on Machame, Lemosho and Rongai are busy in the evenings, so book your route and dates well ahead. Summit success rates are at their highest for the year. Pairs well with an early Mara River crossing safari.
August ★★★★★
The busiest month on the mountain, and for good reason. The weather is at its most steady and predictable, the skies are usually clear, and at the same time the Mara River crossings in the northern Serengeti are at their peak. If you’re planning Kilimanjaro plus a Migration safari, August is the classic choice. Book months ahead.
September ★★★★★
Just as good as August for weather and conditions, and the Mara River crossings carry on through September. The crowds start to thin a little toward the end of the month, so late September is a really nice time to go: almost peak conditions with a quieter mountain.
October ★★★★☆
The dry season starts winding down in October, but conditions stay very good for most of the month. The mountain is much less busy than from July to September, and the Serengeti safari season is still very good. It’s a good-value month that people often overlook. The short rains usually arrive at the very end of October or in November, so keep an eye on your exact dates.
November ★★★☆☆
The short rains arrive in November. The rain is lighter and more predictable than in the long rains, but it’s still rain. Clear mornings are common, and some climbers have a great time in early November. As the month goes on, the weather gets less reliable. We don’t recommend mid-to-late November, though it can work if you’re flexible and know what to expect.
December ★★★★☆
December is a better month than many people think. The short rains usually ease off by mid-December, and lots of climbers come over Christmas and New Year to mark the occasion with a summit, setting off at midnight under the stars. We run a special 7-Day Machame Route New Year departure for just this. Conditions in late December are usually good, and clear summit mornings get more common as January gets closer.

Which Route to Choose for Your Season
The month is only half of it. The route you pick, and how many days you take, matter just as much for your safety and your chance of reaching the top. Here’s a quick guide to matching the route to the season:
For January and February
Every route is in good shape. The Lemosho Route and Machame Route are especially lovely at this time, with clear views over the southern plains toward the Serengeti. The Rongai Route, which starts on the north side, is even drier and very good in these months.
- 7-Day Lemosho Route, our top pick for these months
- 7-Day Machame Route
- 7-Day Rongai Route
- 6-Day Marangu Route
- 9-Day Northern Circuit Route, the most time to acclimatize
For June through October
Every route is in very good shape. The Machame Route is at its most scenic and most popular now. The Northern Circuit is a great choice if you want a quieter trail even in high season, because few climbers use the remote northern side. The Lemosho Route is still our overall favorite for its scenery and its slow, steady climb profile.
- 8-Day Lemosho Route
- 8-Day Machame Route
- 8-Day Crater Machame Route
- 10-Day Northern Circuit Route
- 7-Day Rongai Route
- 7-Day Shira Route
- 9-Day Crater Lemosho Route
For December (New Year)
Climbing Kilimanjaro over New Year is something special: you reach the summit just as the new year begins. We run a departure planned around exactly that.
Other Peaks Worth Considering
If Kilimanjaro’s main climbing seasons don’t fit your dates, Tanzania has two other great mountains. They work well instead of Kilimanjaro, or as warm-up climbs before it:
- Mount Meru: Tanzania’s second highest mountain at 4,566 meters, and one of the most underrated climbs in East Africa. The route takes you through forest and around the crater, and you’ll often see wildlife on the way. You can do it as a 3-day or 4-day climb, and it’s a very good acclimatization climb before Kilimanjaro.
- Mount Oldoinyo Lengai: an active volcano and a sacred mountain for the Maasai, unlike any other mountain in Africa. You can do it as a 3-day trek or a 7-day climbing trip. You climb at night and watch the sunrise over Lake Natron from the top.
How to Prepare for Any Season on Kilimanjaro
Whichever month you choose, the basics of getting ready stay the same, and getting them right makes a big difference to your climb.
Train Before You Go
You don’t need technical climbing skills for Kilimanjaro, but you do need good stamina and strong legs. Start training with hiking, stair climbing and cardio at least three months before your climb. If you can, spend some time walking hills with a loaded backpack. The fitter you are, the better your body copes with altitude.
Choose a Longer Itinerary
Whatever route you pick, go for the longer version if you can. An extra day on the mountain really helps your body adjust, and it improves your chance of reaching the top. The difference between a 6-day and an 8-day itinerary can be big. We explain this in much more detail in our guide to the safest Kilimanjaro routes and acclimatization.
Pack for the Cold in Every Season
Even in January and February, summit night at Uhuru Peak is well below zero. A good sleeping bag rated for the cold, a down jacket, thermal base layers, waterproof outer layers, warm gloves, a balaclava and gaiters are all must-haves. See our full safari and trekking packing list for everything else.
Sort Out Your Health Prep Early
Visit a travel health clinic at least six weeks before you leave. Talk about how to prevent altitude sickness (including whether Diamox is right for you), get any vaccinations you need, and stock your medical kit properly. Our immunization and medical kit guide covers everything.
Get Comprehensive Travel Insurance
High-altitude trekking needs specialist travel insurance that clearly covers Kilimanjaro’s altitude and includes emergency helicopter evacuation. This isn’t optional, you really need it. Our travel insurance guide explains what to look for in a policy.
Join a Group or Go Private
If you’re traveling on your own or want to keep the cost down, joining a set group departure is a great way to climb. You share the trail, and the summit, with people who want the same thing, and you save a good amount of money. Check our upcoming group departures to find a date that suits you. If you’d rather go private, we’ll plan a climb just for you.
Combine Your Kilimanjaro Climb with a Tanzania Safari
Few trips feel as good as reaching the top of Kilimanjaro and then heading down for a Tanzania wildlife safari. The change is huge: the quiet and hard work of the mountain, then the noise and the animals of the Serengeti plains. Many of our guests tell us it’s the best two weeks of travel they’ve ever had.
We’ve put together combined trips for exactly this:
- 10-Day Kilimanjaro Combine Tour
- 11-Day Kilimanjaro Combine Tour
- 10-Day Kilimanjaro Climb and Safari
- 11-Day Kilimanjaro Climb and Safari
You can also browse all our Tanzania combination safari options, or have us plan something just for you with our tailor-made tour service.
Our Final Recommendation
If we had to pick the single best month to climb Kilimanjaro, it would be February: very good conditions, fewer people than in high season, and the chance to add a calving season safari in the Serengeti. Close behind are January, August and September, each very good in its own way.
But honestly, the best month is the one that works for your life, your schedule and the people you’re traveling with. With a good operator, the right route, enough days and proper preparation, you can have a great climb on Kilimanjaro in any season.
