Zanzibar is a year-round tropical destination, but choosing the best time to visit Zanzibar depends on what you want to do during your holiday.
Whether your priority is relaxing on white-sand beaches, snorkeling around coral reefs, exploring Stone Town, taking Zanzibar excursions, enjoying a romantic honeymoon or combining Zanzibar with a Tanzania safari, different months offer different advantages.
Zanzibar experiences a tropical climate with warm temperatures throughout the year. However, rainfall varies seasonally. The Tanzania Meteorological Authority identifies Zanzibar as part of Tanzania’s bimodal rainfall region, with the main long rains from March to May and short rains from October to December. January and February are relatively dry, while June through September are generally dry months.
For most travelers, June to October is the safest overall choice for a classic Zanzibar beach holiday, while January and February are also excellent for warm weather, beaches and marine activities.
But there is no single perfect month for everyone.

Is Zanzibar Worth Visiting During the Rainy Season?
Yes.
One of the biggest misconceptions about Zanzibar’s rainy season is that it rains constantly.
Rainfall patterns vary, and a rainy-season holiday can still include plenty of enjoyable weather.
The main consideration is flexibility.
If your holiday is built around several boat excursions, it is wise to leave some flexibility in your itinerary so activities can be moved if weather or sea conditions become unsuitable.
For travelers who prioritize beaches and predictable weather, the dry season remains the safer choice.
Zanzibar Weather: What Temperatures Should You Expect?
Zanzibar has a warm tropical climate throughout the year.
Tanzania Meteorological Authority data indicates that temperatures are generally higher from around October through February/March, while cooler conditions occur during the May–August period.
Because Zanzibar is surrounded by the Indian Ocean, humidity can be noticeable, particularly during warmer periods.
