The best time to visit Zanzibar is during the dry season, which runs from June to October. During this period, the weather is mostly dry and sunny, with lower humidity levels and cool evenings. Temperatures during this time range from around 25°C to 30°C (77°F to 86°F).
Additionally, the dry season is an ideal time for outdoor activities like snorkeling, scuba diving, and swimming, especially as the waters are calmer and visibility is better.
Another good time to visit Zanzibar is during the short dry season, which occurs from January to February. Although it is a brief period, visitors can enjoy sunny days with less rainfall, which allows for more outdoor activities.
It’s important to note that Zanzibar experiences two rainy seasons - the long rains from March to May, and the short rains in November and December. During these periods, the island experiences heavy rainfall and high humidity levels, which can make it difficult to enjoy outdoor activities.
Overall, the best time to visit Zanzibar is during the dry season, from June to October, when the weather is good, the waters are calmer, and there are many outdoor activities to enjoy.
