The best time to visit Zanzibar depends on what kind of holiday experience you’re after, but most travelers find the island at its most enjoyable during the dry seasons, when weather conditions are ideal for beach activities, cultural tours, and diving. The two main dry periods June to October and December to February offer the best combination of sunshine, clear skies, and warm ocean waters, making them perfect for everything from snorkeling to relaxing on Zanzibar’s famous white sand beaches.
The June to October window is particularly popular because it aligns with Tanzania’s peak safari season. Many visitors choose to combine a wildlife safari in Serengeti or Ngorongoro with post-safari beach relaxation in Zanzibar. During these months, the humidity is lower, the sea is calm, and temperatures are comfortably warm, averaging between 25°C and 29°C (77°F to 84°F). It’s also an excellent time for underwater visibility, making it ideal for scuba diving and snorkeling around Mnemba Atoll or Chumbe Island.
The short dry season from December to February is another great time to visit, especially for travelers escaping cold winter months elsewhere. The weather is hot and sunny, perfect for enjoying Zanzibar’s coastal beauty, festive atmosphere, and holiday events. This period is also good for diving, dolphin tours, and island hopping, although it’s wise to book accommodations early, especially around Christmas and New Year.
The long rainy season, from March to May, brings heavy downpours and high humidity, often making travel less convenient. While the rain nourishes the lush spice plantations and reduces tourist crowds, it can limit beach time and sea visibility. Some hotels and lodges close temporarily during this time. However, for budget travelers or those seeking a quiet, green escape, it can be a peaceful and scenic time to explore.
The short rains in November are usually lighter and less disruptive, with brief showers typically falling in the late afternoon. While not as popular as the dry seasons, November can still be a good month for travel, with fewer crowds and lower prices.
In summary, the best time to visit Zanzibar is during the dry seasons of June to October and December to February, when the island offers ideal weather, crystal clear seas, and the full range of cultural and beach experiences. Whether you’re planning a romantic getaway, a family holiday, or a safari-and-beach combo, Zanzibar shines brightest during these months.
