January, February and September. That is the short answer — dry weather, tolerable summit nights, and crowds you can live with. The longer answer is that every month trades weather, cold and company differently, so here is all twelve, honestly graded.
Two dry seasons: December to mid-March and June to October. One month to think twice about: April.
Whatever month you land on, the single biggest upgrade is not the calendar — it is taking the longer version of your route. An extra acclimatisation day does more for your summit chances than any month will.
Summit night starts near midnight and you climb by headtorch. Under a full moon the scree is lit well enough that some people switch the torch off, and the glaciers glow on your left as you walk the crater rim. It is the version of summit night you have seen in photographs.
The catch is that everyone else has had the same idea. Full-moon weeks are the busiest summit nights of the year, and on the most popular dates the line of headtorches up the slope looks like a street. A new moon is the opposite trade: no light on the ground, and the best star field you will ever stand under.
Both are worth having. If the moon matters to you, pick your month from the dates above — then give your actual start date to the tool and it will show you the exact moon over your own summit night.
Check the moon on my datesEvery route converges on the same plan: asleep by early evening, woken at 11pm, walking by midnight, on the crater rim for sunrise, at the summit by eight. What changes with the calendar is how cold the dark hours are and how many headtorches are ahead of you.
We wrote the whole night out, hour by hour — the cold hours at 3am, why Stella Point is not the summit, and the ten-minute glacier detour almost nobody takes.

Build my pageJanuary, February and September offer the best balance of dry weather, bearable summit-night temperatures and manageable crowds. July and August have the most reliable weather but the coldest nights and the busiest trails. September is the month many experienced climbers pick: July's dry weather with far fewer people.
April is the wettest month of the year, with mud through the rainforest and regular cloud cover at altitude. Late March and May are also wet. November's short rains are lighter and patchier, so it remains climbable — April is the month most operators would rather you avoided.
Yes. The mountain is open and climbed in every month, and the wet months have real upsides: empty trails, lower prices, and camps you may have to yourself. The trade-off is mud in the forest, more cloud, and wetter gear. If you go in the rains, take the extra day your operator offers.
A full moon lights the scree on summit night brightly enough that some climbers switch their headtorch off, and it makes the glaciers visible in the dark. It is genuinely beautiful — and it is not a secret, so full-moon weeks are the busiest summit nights of the year. A new moon gives you the best star field you will ever stand under and a quieter mountain. Both are worth having; pick the trade-off you prefer.
July and August are the busiest months, followed by the Christmas and New Year fortnight and the full-moon weeks of every dry month. If you want dry-season weather with fewer people, look at September, early December, or the second half of January.
Summit-night temperatures run from about −7 °C in the mildest months to −20 °C in June and July, before wind chill. It is below freezing near the summit in every month of the year, so the difference between months is about how much spare warmth your layering gives you, not whether you need it.
The long rains run from roughly mid-March to the end of May, with April the wettest month. The short rains fall in November and are lighter and less predictable. December through mid-March and June through October are the dry seasons.
Early December is one of the best-value windows of the year: improving weather, quiet trails and lower prices. From around the 20th it fills up very fast for Christmas and New Year and summit nights get busy. The first fortnight is the one to aim for.
We make Kilimanjaro stickers and prints, including the Uhuru Peak signboard — the sign at the end of that night. It is the only thing we sell, and it is why none of this asks you for an email address or an account.
