The best time to climb Mount Kilimanjaro is during the dry seasons, which are December to March and June to October. These periods offer clearer skies and drier, easier-to-hike trails, making the experience safer and more enjoyable. For fewer crowds, consider climbing during shoulder months like September or early December, while avoiding the busiest months of July and August if possible. 

Dry seasons 

December to March: This is the first dry season, with clear, sunny weather and generally good conditions for climbing. January and February are considered ideal months within this period.

June to October: This is the second and longest dry season, known for stable weather and good visibility.

Peak (July-August): These are the busiest months due to summer holidays in the US and Europe, making the mountain most crowded.

Shoulder (June & September): These months are less crowded than July and August but still offer excellent, dry weather. 

Rainy seasons 

March to May: The long rainy season can bring heavy rainfall, making trails muddy and slippery, and often causing clouds to obscure views.

November: The short rainy season brings lighter but still frequent showers. 

Tips for choosing the best time for you

For the best weather: Aim for the peak dry season from June to October, but be prepared for crowds.

For fewer crowds: Consider shoulder months like September, or January and February, when the weather is still good but foot traffic is lower.

For lower costs: Rainy seasons can be cheaper due to lower demand.

For a unique experience:

Climb during a New Moon to see the best possible stargazing.

Climb during a full moon for better visibility during the summit night, but be aware these are popular and book up far in advance.
