Zanzibar: weather by month and temperature. When it’s best to relax

Season for vacations in Zanzibar. Weather on the island by month

The island of Zanzibar is known for being a year-round popular vacation resort. However, there is some seasonality in the weather here as well. Specifically, the seasons on Zanzibar include two rainy and two dry periods of varying duration by month. And vacation on the island is good in any month, you just need to choose the right weather. The island is located just below the equator, so conditions are favorable to rest all year round, and even in the season of heaviest rainfall, the rains begin in the morning, which does not spoil the impression of the weather of African summer.

Holidays in Zanzibar

The rainiest months (March to May inclusive) are the low season, from June to October – the high season. Each has its own advantages, depending on the preferences of holidaymakers. During the rainy season the air during the day gets closer to 30 ° C, and the cost of living in hotels is much lower. In the dry season there is sunny weather and almost cloudless skies. So it is safe to say that on the island of Zanzibar the holiday season lasts throughout the year, just in different months it looks a little different.

High season for holidays in Zanzibar

If your choice for a vacation falls on Tanzania, specifically the island of Zanzibar, a season lasting five full southern summer months is the first thing to consider more closely. The real African beach season on Zanzibar is a time of almost half a year, from early June to the end of October. There is another small tourist summer on the island, it takes in the time of January and February – the same dry season, a little respite before the long rainy period.


The main parameters of the weather in Zanzibar are the degree of warming of the air and water temperature by month. At this time of global climate change, small climatic shifts are felt even here. Usually during the dry season the temperature is constant during all the months of winter in the southern hemisphere (we have calendar summer): around +27…+30°С during the day and +24…+26°С at night. But there are slight changes. For example, during the dry season it may rain unexpectedly and even last for a week. For more information about the weather, you can consult the tour operator Altezza Travel, whose office is located in Tanzania.

Air Temperature in Zanzibar

Let’s look at the weather in Zanzibar by month. During the little dry season (January-February) a couple of days a month there are showers, but otherwise – a typical African summer, the heat can reach up to 33 ° C, and the sea gets as warm as +28 … +30 ° C. February is considered especially dry.

In general, the beginning of the high season (June) can still be marked by a couple of rains, but the sunny weather sets in permanently. In July and August there may be no rainfall at all, the thermometer columns rarely reach +30 ° C, but in September and October it is hotter in summer, the sea gets warmer and more comfortable for swimming, and the rains come only for a few days. These months are the most visited by tourists during the popular season, as the conditions are the most favorable for the beach and swimming. Many people like the high season in Zanzibar, when it is best to relax on the ocean coast.

The choice of summer months is more suitable for those who find it difficult to adjust to the new climatic conditions at an unusual calendar time. But in January and February holidays are good for fans of hot temperatures, in addition, this time in Zanzibar is appreciated by divers as the season of deep-sea fishing, as well as sea turtle watching.

Sea temperature in Zanzibar

Water temperatures during the high season can drop to +26°C, which is considered quite cool for the resort. However, closer to October and November the average sea temperature rises to +28 ° C and more, the bathing season is at its peak.

The presence and intensity of rainfall during the dry season can almost always be predicted: it is a few days during the whole month and not necessarily torrential, but only a few hours. However, as indicated, rare events – downpours for a week – are not excluded. However, these, too, cannot be guaranteed.

Winds and waves in this season for skiing can be caught in July and in the first two months of the year. Tides in Zanzibar don’t just happen, but often have a big impact on the nature of beach vacation. The water can be almost a kilometer deep, and the shore opens up to the horizon. On some beaches, the sea barely touches – depending on the phase of the moon.

Can catch waves in the dry season

The humidity in the dry season is not high, in addition, there are always sea breezes that soften the heat. Therefore, it is much milder than away from the coast. It should be noted that continental Tanzania has no such advantage, and the heat there can reach extreme equatorial values.

Zanzibar in the Dry Season

Since the season is quite long (five months), the beginning, middle and end of the season will have different weather conditions. Thus, the beginning of the season – June – usually with rare and already disappearing rains, decreasing temperatures (here the calendar winter begins), decreasing humidity and the onset of drought. And at the end of the season – November – the temperature rises again, the humidity rises and the sea warms up perfectly.

Due to the change of seasons there is a similar periodicity in the influx of tourists at the Tanzanian resort. The highest prices on the coasts are held from November to February, when the arrivals of holidaymakers are associated not only with the weather, but also with the festive winter traditions.

Low season: Zanzibar is still a resort

The low wet season in Tanzania, Zanzibar Island begins in March, and the weather is almost unchanged by month within the African autumn. Zanzibar is in the monsoon climate belt, their seasonality and high humidity in the archipelago is pronounced, as is the high solar activity. Hot temperatures and constant downpours are not necessarily an attribute of the low season. Thus, during the rainy season, too, a sudden drought can occur.

Number of rainy days in Zanzibar

It starts raining from the last decade of March. In other words, the first spring month (here it is the beginning of autumn, on the contrary) can be regarded as half-typical beach month. But the air gradually cools down to the daily average of +27 ° C and below. The month of April is very rainy – for 3.5 weeks there may be showers and the rest of the days are cloudy, but with real summer temperatures (up to 30). May is almost as rainy, also windy. Towards the end of the month, the sun starts to shine, the downpours stop, and the air and water get warmer and warmer.

Heavy rainfall in Zanzibar

During the big rainy season, although rare, there are such heavy downpours that holidays and services in Zanzibar come to a standstill. During this time, hotels and even entire islands are closed for safety reasons. But mostly the rainfall is moderate and regular. So you can safely plan active and sightseeing leisure – in the low season, bad weather will not be able to spoil the vacation mood. Especially since the temperatures at this time (as never before in the year) are exactly summer temperatures.

Rainfall in Zanzibar

In November and December in Zanzibar again the rainy season. This period is shorter than the longest, and for the whole season may fall as much rain as during March. Particularly in November, the rainfall may take a total of only a decade, and then it is short-lived. December is traditionally the hottest month of the year. The air temperature never drops below 30 ° C 24 hours a day, the humidity is high, the sea is warm and nice for swimming. In addition the Christmas and New Year’s Eve celebrations contribute to the tourist influx.

The temperature during the rainy season in Zanzibar is +30 … +33 ° C during the day and +26 … +27 ° C at night. The sea is still warm, up to +28 ° C, wind and waves are small, but the humidity is at its peak. The tides in low season do not differ from the high, their peculiarities are better to study for a specific location in Zanzibar.

Should wear protective gear

The highest temperatures are just at the typical rainy season – end of the calendar year and early March, at midday peak the sun often scorches to an extreme +40. When preparing to go to Zanzibar, you should take into account the UV index and stock up on protective gear. While the heat at the beginning of heavy rains is still offset by the replenishment of moisture, by the end of May, when the showers dry up and the dryness gets closer, staying in the sun is very dangerous.
