Local Weather in Nungwi | March · April · May

Stunning Skies

During March to May spectacular cloud formations and sunsets are common. You can watch the natural splendour and sunsets from Nungwi Beach.

Rain And Sun

While the daytime temperatures drop to a comfortable level, the weather can be unpredictable. You may experience frequent changes from short heavy showers, sunny spells and tropical rainfalls lasting 1 or 2 hours, to whole rainy and beautiful sunny days.

Actual Weather

While international weather reports indicate the occurence of rain all day long from March to May, this does not correspond to the realtime weather on the ground in Zanzibar North.

Our dive center is located in Nungwi, on the northernmost tip of Unguja Island, commonly called Zanzibar. Here the weather and sea conditions are unique and not to be confused with other parts of Zanzibar or the other islands of the archipelago and the mainland Tanzania.

Best Diving Conditions in Zanzibar North | March · April · May

Visibility Peak !

Zanzibar North is known for great underwater visibility between 20 to 60 metres. Why does this peak in particular in the rainy season?
From March to May the strong winds subside and the Indian Ocean around Zanzibar Island’s north coast becomes very calm. The calmer seas make excellent visibility for divers.

Water Temperatures

The warm waters of the Indian Ocean are also pleasant from March to May. With average water temperatures of 27 degrees Celsius, Zanzibar is a great diving destination throughout the year.

Coral reef in Zanzibar North

Marine Life

There is a wide range of hard and soft corals and more than 500 marine species. It is usual to encounter pods of dolphins, sea turtles, tropical reef fish, a large variety of macro marine life, extraordinary sea creatures and, on occasion, white tip reef sharks.

March to May, as it rains often, the water temperatures in the sea slightly decrease and you can see more fish on the reefs.

With the cooler water temperatures, small fish species such as sardines and pilchards appear at our dive sites. These attract the larger predators such as the barracudas, groupers, kingfish and cobias. March, April and May is the season in Zanzibar when you can encounter bigger fish on almost every dive.


This is the time of year that you could have the boat all to yourself. Enjoy the reef with your personal dive guide and very few other divers to spoil the view.
