May falls within Zanzibar’s “long rains” season, typically experiencing significant precipitation and high humidity. Temperatures remain warm, averaging between 27-29C (81-84F). Ocean temperatures are also pleasant, making water activities still possible. However, the increased rainfall can disrupt outdoor plans and impact some tourist activities. Expect several hours of sunshine each day, interspersed with periods of heavy downpours and occasional thunderstorms.
Understanding the climatic conditions prevalent in Zanzibar during May is essential for travelers planning a visit. This knowledge allows for realistic expectations and facilitates appropriate preparation. Packing rain gear and quick-drying clothing becomes crucial. While the rain might offer a respite from the heat, it can also affect the availability of certain excursions or outdoor activities. Historically, May has been a shoulder season, offering potential cost savings on accommodations and flights compared to peak periods.
