WEATHER AND TIDES
Zanzibar is located off the coast of Tanzania on 6 degrees south in the Indian Ocean. The climate is tropical due to the proximity to the equator.
As everywhere in East Africa, the climate is decisively influenced by the change between the southwest monsoon and the northeast monsoon. These bring rainfalls of different intensity at different times of the year. Zanzibar has two rainy seasons a year.
Southwest monsoon (“Kuzi”)
Heavy rainfall must be expected in the southwest monsoon from late March to late May. The southwest monsoon brings an average of 395 millimeters of precipitation to Zanzibar in April and approximately 310 millimeters in May. However, there is rarely bad weather for many days in a row. The sun often shines during the day, rain typically falls in very violent tropical showers.
Northeast monsoon (“Kazkazi”)
The northeast monsoon causes the so-called “little rainy season”. The rainfall that comes with the northeast monsoon is less than in April or May. In November and December, an average of 134 and 125 millimeters of rain per month, respectively.
In accordance with the tropical climate, there are few fluctuations in temperatures during the year. The temperatures in Zanzibar are high all year round and average between 25 degrees and 28 degrees.
It is the “coolest” from June to August, the highest temperatures are around 30° C, while in the other months it is definitely well over thirty degrees.
The nightly low temperatures range between 23 and 25 degrees in the course of the year, but can drop, albeit rarely, to just under 20 degrees in the cooler months.
The driest time in Zanzibar is between June and October and in January and February with two to five rainy days per month.
