The Best Time To Climb Kilimanjaro
Although it's possible to climb Mount Kilimanjaro all year round, timing is a factor in your chances of a successful summit. There are two optimum climbing periods, both of which coincide with the dry season months of June to October and January to February. At other times of the year, seasonal rains can make the routes slippery and challenging to navigate. January and February are generally warmer than the winter months of June to October (although differences in temperature are minimal this close to the equator). Whatever time of year you decide to climb, make sure to bring cold weather gear, because the top of the mountain is perennially crowned with ice. These rules also apply to Mount Meru, which is located in the same area as Kilimanjaro.
The Best Time to Visit the Coast
If you're headed to the coast for a spot of R&R (or to any of Tanzania's idyllic Indian Ocean islands), the best time to travel is during either of the dry seasons. The March to May rains are unusually heavy on the coast, making this time of year unreliable for devoted sun worshippers. The storms also disrupt underwater visibility, which can be disappointing for scuba divers and snorkelers.
Spring Spring brings the "long rains" and is considered the low season throughout the country. Many camps will close during these months, but it's easier to find good deals on lodging, and you won't see as many other tourists.
