The best time to hike Kilimanjaro is during the dry season, which runs from January through February and then again from June through October. This is when temperatures are milder and snowfall on the mountain has decreased significantly. During these months, you will also have more stable weather with fewer chances of rain or strong wind that could disrupt your trekking plans. Additionally, there are usually fewer crowds as this period falls outside of peak tourist season. Ultimately, if you want to maximize your chances for success when summiting Kilimanjaro and enjoy the most pleasant trekking conditions possible, it is recommended that you plan your trip for one of these two periods in the year.
