Best time to go to Zanzibar  

The island of Zanzibar is renowned for its idyllic sunshine shining down on its white sand beaches and azure waters. Although the island is accessible year-round, there are particular months that are deemed better to travel to Zanzibar.

It’s hot all year round on Zanzibar, but avoid Tanzania’s torrential March to early May rainy season if you want to make the most of its beautiful beaches and spectacular diving. Travel in the June to October dry season for guaranteed, uninterrupted sunshine, with temperatures hovering around 30°C. Read on for more information on the best time to go to Zanzibar, and travel advice from our Zanzibar experts.

When it’s hot, it’s very, very hot, and when it’s wet, it’s horrid. Well, in March to early May anyway, when the long rains bring daily torrential downpours, high humidity and churned-up, silty seas. Outside these times, most visits to Zanzibar will be pleasant, with dry, sunny June to October peak season on the beach (and in Tanzania’s game reserves if you’re on safari first). 

January to March are also hot and dry, but quieter, and while November to December bring Zanzibar’s short rains these tend to be isolated showers which won’t lead to a holiday washout. Temperatures hover around 30°C all year round. 

March, October and November are generally considered the best for diving and snorkelling – with warm seas, little wind, and excellent visibility. Whale sharks can be seen from September to December.

Best time to go to Zanzibar   - By Months

December to January:

During this period, from around mid-December to early January, the hotels in Zanzibar will either offer their high or festive rates, and some will emphasise that their special offers are not applicable. It is also worth bearing in mind that a few of the properties will have a minimum night stay such as 5 nights. The festive period in Zanzibar is a very popular time to travel, and with many of the hotels offering special dinners, local entertainment or romantic celebrations, it’s no wonder why!

April to May:

Whilst many perceive Zanzibar as an island of year-round sunshine and warm temperatures, it is important to know that Zanzibar has a period of long and heavy rains. During the months of April and May, tropical downpours throughout the day are the norm. As a result, the majority of hotels on Zanzibar island are closed for these two months and use the time to their advantage to complete any renovation work on the hotel or facilitate training to the full-time staff.

June to October:

The months of June to October are regarded as the peak months to travel to Zanzibar. The weather is warm and reliable, with strong rays of sunshine glistening on the Indian Ocean. As thousands of tourists make their way to Zanzibar during these months, many of the properties offer special offers to make them competitive on the island. These can be anything from long stay discounts and free nights’ accommodation, to complimentary lobster dinners on the beach for honeymooners. If you are planning your trip to Zanzibar during these months, we would highly recommend booking in advance to

How to get to Zanzibar
November to March:

The month of November and early December brings the short rains to Zanzibar Island, which are more sporadic and much lighter than the main rains in April and May. The months between January and March are hot and dry and similarly, a good time to visit Zanzibar. These months are generally a little quieter than the June to October window so there tends to a greater choice of availability and special offers.
