The Best Time to Climb Kilimanjaro: An Honest Month-by-Month Guide

The best time to climb Kilimanjaro is during its two dry seasons: January to early March and June to October. These months bring the clearest skies, the most stable trails and the highest summit success rates. April, May and November are the wettest months and are best avoided. But here is the honest truth most guides skip past: the month you choose matters far less than the number of days you spend on the mountain. Get that part right and almost any month can work. Get it wrong and the perfect month will not save you.
The short version
Best overall
January, February, September and early October. Great weather, and not quite as packed as high summer.
Driest and busiest
July and August. Spectacular and reliable, but the trails are at their fullest.
Quietest good months
June and September. Dry-season weather with thinner crowds.
Best avoided
April and May (long rains) and November (short rains).
Kilimanjaro does not have four seasons
Sitting almost on the equator, Kilimanjaro does not follow the spring-summer-autumn-winter pattern most of us grew up with. Instead it has two dry seasons and two wet ones, driven by a band of tropical rain that drifts north and south across the continent through the year. So the question is never really about temperature, which is governed far more by altitude than by the calendar. It is about rain, visibility and how busy the mountain is.
One thing the seasons do not change: the summit is always brutally cold. Whatever month you choose, expect summit-night temperatures somewhere between minus ten and minus twenty degrees Celsius, dipping colder still in July and August, even as the base of the mountain sits warm in the twenties or low thirties.
The two best windows
June to October, the long dry season
This is the most reliable weather of the year: clear skies, stable trails and the highest summit success. It is also the busiest, because it lines up with the European and North American summer holidays. July and August are the peak of the peak, gloriously clear but crowded, with queues at famous pinch points like the Barranco Wall on the popular routes. If you want this weather with a little more breathing room, June and September are the sweet spots, and many seasoned guides quietly rate September and early October as the best all-round time on the mountain, with excellent conditions and crowds thinning as the summer break ends.
January to early March, the short dry season
The hidden gem. These months are often warmer and just as clear as high summer, with noticeably fewer people and frequently better value. You may see a dusting of fresh snow near the summit, which makes for spectacular photographs. For a lot of climbers, January and February offer the best balance of weather, quiet and price of the entire year. If peak season feels too busy or too dear, this is your window.
The months to be careful with
April and May are the long rains, and the wettest, most challenging time to climb. Muddy trails, low cloud, poor visibility and meaningfully lower success rates. The one upside is solitude. November brings the shorter rains, greener and quiet but less predictable. If your dates fall in these months and cannot move, the Rongai route and the northern side of the mountain sit in a rain shadow and stay noticeably drier, so they are the smart choice when the skies are against you.
The truth most operators will not tell you. Summit success in the dry season runs around 85 to 95 per cent on a proper seven to nine day route. In the wet months it can fall to 60 or 70 per cent. But the single biggest predictor of whether you reach the top is not the month at all. It is the number of days you spend acclimatising on the mountain. An eight-day Lemosho climb in a "wrong" month will beat a rushed five-day climb in perfect July weather, every time. The industry-wide average success rate sits around 65 per cent, and it is dragged down not by weather but by short itineraries and budget operators cutting corners on acclimatisation. So choose your days first. Then choose your month.
Crowds, solitude and the full moon
If sharing the mountain bothers you, avoid July and August, and lean towards June, September, or the quieter routes such as the Northern Circuit, Rongai and Lemosho, which spread climbers across more space. And if you love a bit of magic, consider timing your summit night for the full moon. The moonlight lights the final ascent and softens the need for head torches, and it is one of the most sought-after experiences on Kilimanjaro, so those dates book up early.
Climbing Kilimanjaro and a safari together
Most people who travel all the way to Tanzania pair their climb with a safari, and the timing works beautifully alongside the Great Migration. For the dramatic river crossings in the northern Serengeti, climb in the June to October window. For the calving season in the southern Serengeti, with newborns and plenty of predator action, the December to March window lines up perfectly. Either way, you finish the hardest thing you have ever done and then get to recover with your feet up, watching the plains.
Kilimanjaro month by month
January EXCELLENT
Short dry season. Clear, warmer days, fewer crowds than high summer and often better value. Possible light snow up top.
February EXCELLENT
Often the warmest and clearest month of all. Superb visibility. One of the best times to climb.
March GOOD EARLY
Fine in early March, then the long rains arrive mid-month. Late March is wet, with Rongai the safer bet.
April BEST AVOIDED
The peak of the long rains. Muddy, low cloud, lower success. Quietest month, for the truly flexible only.
May MOSTLY AVOID
Long rains easing, and late May can improve sharply. For experienced, weather-hardy climbers.
June VERY GOOD
Dry season opens. Cooler, clear and quieter than the months that follow. A lovely sweet spot.
July EXCELLENT
Reliable, clear, spectacular, and the busiest month. Coldest summit nights. Book well ahead.
August EXCELLENT
Peak weather and peak crowds alongside July. Stunning, cold and busy.
September BEST ALL ROUND
Excellent conditions with crowds thinning as the holidays end. Many guides' favourite month.
October VERY GOOD
Quiet and clear early on. Late October can see the first short rains begin to creep in.
November SHORT RAINS
Greener and peaceful, but wetter and less reliable. Rongai and the northern side stay drier.
December GOOD
Improving after the short rains. Festive climbs are popular, with clear spells and fewer crowds early on.
So when should you climb?
It comes down to what you value most. Want the clearest skies and the best photographs? Climb in the dry seasons. Craving solitude? Choose June or September, or a quieter route. Watching the budget? January and February often give peak-season conditions at gentler prices. Dreaming of snow on the summit? Aim for January to March. Happy to trade weather for an empty mountain? The shoulder months reward the experienced and the well-prepared.
Whatever you choose, remember the one rule that beats all the others: give yourself enough days. The right month is a bonus. Enough time to acclimatise is what gets you to the top.
Frequently asked questions
What is the best month to climb Kilimanjaro?
The strongest all-round months are January, February, September and early October, which combine excellent weather with fewer crowds than July and August. July and August have the most reliable conditions but the busiest trails.
What is the worst time to climb Kilimanjaro?
April and May, the long rainy season, are the most difficult, with muddy trails, poor visibility and lower success rates. November, the short rains, is also less reliable. If you must climb then, the drier Rongai route on the northern side is the best choice.
Can you climb Kilimanjaro year-round?
Yes, Kilimanjaro can be climbed in any month. The dry seasons simply offer better weather and higher success. In the wetter months, route choice and proper preparation matter more, and the northern routes stay drier.
Does the time of year affect summit success?
It does, but less than people expect. Dry-season success runs around 85 to 95 per cent on a good seven to nine day route, versus 60 to 70 per cent in the wettest months. However, the biggest factor in reaching the summit is the number of days you spend acclimatising, not the month you choose.
When is the best time to climb Kilimanjaro and go on safari?
Both work well together. Climb between June and October to catch the Great Migration's river crossings in the northern Serengeti, or between December and March for the calving season in the south. The dry climbing seasons line up neatly with prime game-viewing.
