When to Go
There are two rainy seasons: the short rains (mvuli) October through December and the long rains (masika) from late February to early May. Given the influence of global warming, these rains aren’t as regular or as intense as they once were. It's best to avoid the two rainy seasons because many roads become impassable. Ngorongoro Crater is open all year, but the roads become extremely muddy and difficult to navigate during the wet seasons. High season is January through the end of September, but prices are much higher during this time. Make sure you find out in advance when the lodge or destination of your choice is closed as many are open only during the dry season. The coast is always pretty hot and humid, particularly during the rains, but is cooler and more pleasant the rest of the year. The hottest time is December just before the long rains. In high-altitude areas such as Ngorongoro Highlands and Mt. Kilimanjaro, temperatures can fall below freezing.
