Tanzania lies within the tropics and enjoys a pleasant climate with distinct dry and rainy seasons. The rainy seasons tend to occur between late March and early June and again between mid November and the end of December. The remainder of the year is mostly dry.

Much of the country lies at altitudes where mornings and evenings are cool and the middle of the day is warmed by the equatorial sun. Due to the proximity to the equator, the annual variation in temperature is small. The average temperature during the day is about 85 degrees Fahrenheit, while at night it can drop to as low as 50 degrees Fahrenheit in some areas.
