Best months to visit Mnemba Island

The best time to visit Mnemba Island in Zanzibar typically falls during the dry seasons, when the weather is pleasant, and the sea conditions are favorable for outdoor activities such as snorkeling and diving. Zanzibar experiences two main seasons:

  • Dry Season (June to October):
    • This period is characterized by lower humidity, minimal rainfall, and cooler temperatures.
    • The weather is generally clear and sunny, making it an ideal time for water-based activities.
    • Sea conditions are calm, offering excellent visibility for snorkeling and diving.
    • June to October is considered the peak tourist season in Zanzibar, including Mnemba Island, so it’s advisable to book accommodations well in advance.


  • Short Dry Season (December to February):
    • This season is also relatively dry, with warm temperatures and less humidity.
    • While there might be occasional short rains, they are usually not enough to significantly impact travel plans.
    • This period is another good time to visit Mnemba Island, with pleasant weather for beach activities and marine excursions.

*It’s important to note that the months between March and May constitute the long rainy season in Zanzibar. During this time, there is a higher chance of heavy rainfall and storms, which can affect sea conditions and limit outdoor activities. Therefore, you should avoid planning a visit to Mnemba Island during these months if you want to enjoy the best possible weather.*

Getting to Mnemba Island

If you’re staying at andBeyond Mnemba Island (the only accomodation on the island), they will arrange transportation for you from either Stone Town or the airport.

A stay at andBeyond was way out of our budget on this trip, so we just took a few hour trip to the Mnemba Island Atoll for some stunning snorkeling.

Our hotel arranged a tour for us including a driver + boat trip. We paid around $60/person for our tour.

If you’re planning to visit on your own, the easiest way to get Mnemba Island is to drive to Matemwe Beach. There you will find countless small boats waiting to take people on dolphin tours or snorkeling at Mnemba Atoll. *see our photos below*

Snorkeling & Diving at Mnemba Atoll

Snorkeling at Mnemba Atoll in Zanzibar is a captivating experience and was some of the best snorkeling we’ve ever seen! We had the opportunity to explore some of the most pristine coral reefs and marine life in the Indian Ocean. Mnemba Atoll’s protected marine reserve status ensures that the underwater ecosystem remains vibrant and diverse.

Coral Reefs:

The atoll is surrounded by coral reefs. The coral formations provide a habitat for a wide variety of marine life, making it an ideal spot for snorkelers and divers to witness the beauty and diversity of the underwater world.

Marine Life:

We encountered a rich array of marine life while snorkeling. There’s the possibility of seeing colorful reef fish, sea turtles, rays, and even larger species such as dolphins (more on the dolphins later). The clear, turquoise waters enhance visibility, allowing for a close-up view of the underwater inhabitants. Even on an overcast day, we found the visibility to be excellent!

Guided Snorkeling Tours:

Many resorts and tour operators in Zanzibar, especially those in proximity to Mnemba Atoll, offer guided snorkeling tours. Experienced guides accompany snorkelers, pointing out interesting marine life and ensuring a safe and enjoyable experience.

Equipment Rental:

If you’re not traveling with your snorkeling gear, most snorkeling excursions at Mnemba Atoll provide the necessary equipment, including masks, fins, and snorkels. We opted to bring our own masks and snorkels because we don’t like sharing.

Scuba Diving:

We were planning to go scuba diving in Zanzibar, but we ended up running out of time during our trip. Here are some dive centers that were recommended to us by other divers –

Cost of visiting Mnemba Atoll

As mentioned above, numerous tours are available for you to explore. Opting not to make reservations through your resort and instead approaching a local by their boat is likely to result in a better deal. Prices for tours arranged through a tour company start at approx. $40 for a half-day snorkeling excursion in Mnemba Atoll and dolphin watching.

Dolphin watching & swimming with dolphins

While this is an extremely popular activity near Mnemba Island and in other areas of Zanzibar, it is a bit controversial. The manager from our hotel let us know that most of the dolphin tours are quite unethical. This is because there are often many boats chasing the dolphins so people can jump in and swim with them. Unfortunately, this puts a lot of stress on the dolphins.

Swimming with dolphins was at the top of my bucket list, but I didn’t want to support the unethical behavior of chasing the dolphins. My husband and I decided that we’d only swim with the dolphins if there were very few boats and we saw the dolphins along our route heading to Mnemba Island.

Luck was on our side because it was a rainy day and lots of tourists weren’t going on the boat trip. We decided to go anyway. Once we started heading toward Mnemba Island there were about 40 dolphins that decided to join us! Calmly, we jumped off the boat and swam with them for 5-10 minutes until they decided to move along. It was a truly magical experience and I’m so glad we did it.

If you are considering doing a dolphin watching tour or swimming with them, please don’t go on a day where there are tons of boats and people jumping off everywhere. Visit on a rainy day or during off season and see if the dolphins approach your boat on their own.
