Tanzania can be visited at any time of the year but some months are just better than others. There are two rainy seasons; however, due to the impact of global warming, these rains are no longer consistent and overwhelming compared to when they once were. The short rainy season lasts from October to December, and the long rainy season lasts from late February through early May. The two rainy seasons represent the low season, while the dry seasons of the year represent the high or peak season for tourist activities.

Travelling to Tanzania during the rainy season has both advantages and disadvantages. However, while this is solely dependent on what destination you choose to visit, the major disadvantage of the low season is that the majority of the roads in remote places are impassable and the wildlife can be hard to locate. Some places can sometimes get chilly-cold during early morning and nighttime, but the daytime is relatively dry and sunny. Conversely, travelling to Tanzania during the rainy (low) season can provide you with the opportunity to take advantage of inexpensive flights, which in most cases you will typically have to work for them since you will need to fly-in through a connecting flight. This is also the best time for honeymooners and anti-social individuals who prefer being among fewer crowds.
