The best time to travel Zanzibar is during the dry seasons, from June to October and December to February. These months offer warm, sunny weather with lower humidity, making it ideal for enjoying the beaches, snorkeling, and exploring the island’s cultural sites. The rainy seasons, from March to May and November, bring heavy showers that can disrupt outdoor activities. However, visiting during the off-peak months can mean fewer crowds and more affordable rates, but the weather may be less predictable.
