Zanzibar, Tanzania Weather and Climate

Geographical location

According to abbreviationfinder, Zanzibar is a group of islands off the mainland of Tanzania and has the status of a semi-autonomous state.

This means that the former British protectorate of Zanzibar still enjoys a special status in Tanzania today. Zanzibar has its own government, president and parliament.

After several revolts as a result of its declaration of independence, the archipelago finally became part of the new state of Tanzania in April 1964 together with Tanganyika. The Zanzibar archipelago includes the two islands of Pemba and the main island of Unguja, which tourists perceive as “the island of Zanzibar”.

In addition, various smaller islands belong to the administrative area. Even today, Zanzibar is predominantly Muslim (mainland Tanzania is mostly Christian) and especially in the capital Stone Town – also known as Zanzibar City – the oriental heritage of the former sultanate can still be felt in everyday life.

The islands of Zanzibar were under the rule of the Sultanate of Oman from 1698 to 1861.

Climate in Zanzibar

When we look at the climate in Zanzibar, we mainly refer to the main island of Unguja, on which, in addition to the beautiful Stone Town, there are also numerous high-class hotels and beach resorts. Nevertheless, our climate tables and recommendations also apply to all other islands in the Zanzibar archipelago. Basically, due to the location in the immediate vicinity of the equator, a strongly tropical climate prevails.

This is characterized by year-round high temperatures with values ​​above 29 degrees Celisus (during the day), even at night the thermometer never falls below 18 degrees during the year. The Indian Ocean moves with water temperatures between 25 degrees in August and 30 degrees in March year-round in the bathing area. The weather is determined by two dry seasons and two rainy seasons on Zanzibar.

The short rainy season is with the onset of the Kaskazi monsoon in November and December with rather light rainfalls, whereby the second half of December around Christmas can be very pleasant again. The great Zanzibar rainy season from mid-March to the end of May is much more pronounced, the weather is now very changeable and some hotels are temporarily closed.

When is the best time to travel to Zanzibar?

During the rainy season, the prices for flights and hotels on Zanzibar are usually comparatively cheap, but there is always the risk of clouds, strong winds and rain. The best time to travel to Zanzibar is therefore in the very hot months from the end of December to the end of February.

This period is particularly popular with Europeans and is therefore considered the main season in Zanzibar.

Our recommendation for the best travel time is above all the long dry season from June to October, because there is now the perfect mix of good weather and manageable visitor numbers on the beautiful island in the Indian Ocean. This “tropical winter” on Zanzibar and other islands on the East African coast (e.g. Mafia or Mozambique) cools down pleasantly at night and is very easy to bear during the day with around 50-60% humidity.
