The main weather parameters in Zanzibar are the air temperature and the water temperature. Currently, global climate change is causing slight shifts in climate even here. Usually during the dry season, the air temperature is constant during all the months of the winter of the southern hemisphere. During the day about +27 to +30 ° С, at night +24 to +26 ° С. But there are small changes. For example, in the dry season it may unexpectedly rain and even drag on for a week.

Consider the weather in Zanzibar across high season months.

  • January-February – in this small dry season it generally showers a couple of days a month, but otherwise there is a typical African summer where the heat can reach 33 ° C, and the sea warms up to +28 to +30 ° C. February is considered especially dry.
  • June – In general, the beginning of the high season in June can still be marked by a couple of rains, but sunny weather is finally there to stay for the next few months.
  • July-August – there may be no precipitation at all, and the mercury rarely reaches +30 ° C.
  • September-October – it is hot, the sea is warmer and more comfortable for swimming, and it rains only for a few days.

These months are most visited by tourists, since the conditions are 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.

But in January and February, lovers of hot temperatures can rejoice given the constant sunshine. Moreover, this time in Zanzibar is appreciated by divers as a season for deep sea fishing, as well as observations of sea turtles.

The infrequent showers in the dry season can almost always be predicted. When it pours, then the rain is not necessarily torrential, and lasts only a few hours. However, as indicated, rare events cannot be not ruled out – showers lasting a week have been observed in the past.

The water temperature in the high season can drop to + 26 ° C, which is considered pretty cool for a beach holiday. However, closer to October and November, the average sea temperature rises to + 28 ° C and more, and the swimming season is at its peak.

How is Zanzibar in the dry season

Wind and waves in this season for surfing can be caught in July and then in January and February.

Zanzibar not only gets tides, but they often have a great influence on the nature of beach holidays on this island. Water level can recede into the sea by almost a kilometer, and the coast opens to the horizon. On the other hand, on some beaches like Nungwi, the sea almost does not move depending on the phase of the moon.

Humidity in the dry season is low. In addition, sea breeze is constantly present, which somewhat softens the heat. It should be noted that continental Tanzania does not have such an advantage, and the heat there can reach the extreme equatorial values.

Zanzibar in the dry season

Since the high season in Zanzibar is quite long (five months), the weather in this period is different at the beginning, middle and the end.

The beginning of the season in June usually witnesses rare and already disappearing rains, lowering temperature (winter in Zanzibar begins in June), decreasing humidity and the onset of drought. And at the end of the season in November the temperature rises again, the humidity arrives, and the sea warms up perfectly.

In connection with the change of seasons, a similar periodicity is observed in the influx of tourists to Tanzania. The highest prices on the coast are held from November to February, when the arrivals of vacationers are associated not only with the weather, but also with festive winter traditions.
