Tanzania is situated almost at the equator and due to this the weather is rather stable with a comfortable and temperate climate. Never reaching extremely hot temperatures or very cold weather, the average annual temperature varies from +25°C on the south of the country to +27°C on the north.

Of course, in Kilimanjaro and in places such as Ngorongoro crater, the temperature sometimes falls below zero, especially at night time, therefore it is necessary to take warm clothes even to safari. Many people try to avoid the rainy seasons in Tanzania which there are two: the first one, that is the longest, is between end of March to May; the second one is between end of October to the first half of December. In the rainy season there is really more of precipitation. The table below gives an approximate annual estimate.

The average annual precipitation (mm) in Tanzania:

Jan Feb Mar Apr May Jun Jul Aug Sen Oct Nov Dec
49 30 85 153 126 32 13 18 21 48 132 75

All big TV companies such as Discovery / National Geographic come to film their stories just in rainy seasons when the nature is very colorful, the grass is lush green color and, again, there are no others groups that could interfere the high quality photos. But, it seems, what advantages could be of the trip to Tanzania in the rainy season?

The dust on the road. For the most part, 50% of dust enters the interior of the vehicle on safari from passing safari jeeps and if you have an open roof or window, the big portion of dust enters from others cars.

In low season the cost of the hotel and safari is notably lower. The hotels are one of the main factors of the high price of safari tours but in low season prices go down that allows you saving much money thus obtaining comfortable hotels. 

Among disadvantages of low season, we can mention only one: 

due to poor road conditions, more remote parts of the Serengeti National Park are inaccessible, but even in high season they are very seldom visited because of the remoteness of areas. In the rainy season a part of hotels is also closed for annual maintenance, especially it concerns hotels situated in Zanzibar.
