Zanzibar Weather June: 7 Things to Know About Rain, Wind and Sunshine

Planning a trip to Zanzibar in June and wondering if you will have sunshine, rain, calm sea or strong winds? Zanzibar Weather June is warm and dry, with significantly less rainfall than May, making it suitable for outdoor pursuits. Zanzibar starts its long dry season in June, but not every day is the same.

The daytime temperature is typically in the 28-29°C range, and nights are warm and comfortable. Rainfall decreases, humidity starts to wane, and the sun returns. Meanwhile, the south-east trade wind or Kusi starts to become more prominent throughout the month.

So, what is the weather like in Zanzibar in June? Well, it's good news for most travellers because the June weather in Zanzibar is perfect. Most beaches, sightseeing, snorkeling and time on the water are generally good in June, but wind and daily sea conditions should be taken into consideration. Here are 7 things you should know before you travel. 

1. Zanzibar Weather June Is Warm Without the Heaviest Humidity

June is warm and tropical, but the weather is in general more comfortable than in the wetter months leading up to it. The historical averages for June are approximately 28°C in the day and 24°C at night. Beaches and swimming are still warm, and lower humidity levels make walking, sightseeing and outdoor activities more comfortable.

When searching for June weather in Zanzibar, you'll notice that the temperatures don't drop significantly when the rainy season has ended. Zanzibar is still a tropical paradise and even nights are generally not cold enough for heavy clothing. 

What Does June Weather Actually Feel Like?

Warm mornings, sunny periods, sea breezes and comfortable evenings. Sunscreen, water and hat are still a must at midday when the sun is still powerful. The Indian Ocean breeze adds a fresher quality to the coast than to the interior of the country. This can make June a very nice month to visit if you are headed to the beaches or on a boat.

For those who are staying on the north coast, Kendwa & Nungwi private tours allow you to plan time with the water based on the day's conditions. 

2. June Brings Much Less Rain Than May

The most significant factor that makes June so popular for travelers is the weather. According to long-term records, the average rainfall for June is about 40.65 mm, while May averaged about 189.36 mm. The WeatherAPI climate record also shows around 4 rainy days per month in June. It's one of the most significant transitions in the year. 

When looking for weather in June in Zanzibar, the first thing to keep in mind is that there is still a chance of rain, but June is typically much drier than April or May. 

Does It Rain All Day in Zanzibar in June?

Usually, no. June is still somewhat of a long rainy month, although not as strongly as other months, but there is a potential shower risk around the start of the month, especially. Beaches, sightseeing or boat trips have more dry periods when they are useful.

If you have a weather app that displays a rain symbol, do not change your plans for the whole day, go to the hourly forecast and the local conditions first. 

Is Early June Wetter Than Late June?

Early June may have some lingering rainy-season weather, and later June generally has more consistent dry-season weather. This doesn't mean the trip will be entirely dry in late-June. Although tropical weather can be erratic at any time, you can expect to experience more of a dry season as the season shifts.

If you want to see what comes immediately before June, compare conditions with Zanzibar weather April and Zanzibar Weather March. You may also review Zanzibar weather February tips to learn about the transition of Zanzibar as the year advances towards the long rainy season. 

3. Zanzibar Weather June Trends From 2022 to 2026 Show Why Flexibility Still Matters

Average values over the season are helpful but the year-to-year variation provides another important message: June is not the same every year.

WeatherAPI's historical data for June in Zanzibar shows temperature was fairly stable from 2022-26, but rainfall was significantly different. 

The temperature range was very small. Average temperatures remained around 23°C at night and 27°C to 29°C during the day across the five years. Rainfall was much less consistent.

June 2022 recorded only 20.73 mm, while June 2025 recorded 188.95 mm. Although June is usually called a dry season month, one year may be wetter than another.

The five years are helpful for recent travel contexts, but this is not a sufficient period to identify a long-term climate trend. Always consult an up-to-date forecast, not historical averages. 

Did You Know?

The total amount of rainfall received in June 2025 was around 168 mm more than that of June 2022, but the average minimum temperature for the nights in both the years were about 23°C. That's a good illustration of how the rains can fluctuate significantly from one June to another, and the temperatures stay really very close. 

4. Wind Becomes More Noticeable as June Progresses

June is not just about reduced rain, it's also about wind patterns. The southeast trade wind, known as the Kusi, becomes established during this part of the year. It can be especially prominent in mid-June along more exposed sections of the eastern coast of Zanzibar.Winds increase noticeably along Zanzibar's east coast during this time causing some changes to sea state and beach conditions, as well as affecting some activities on the boat.

When you're asking yourself the question "how is the weather in Zanzibar in June?," it's important to take more than just temperature and sunshine into account. Even a perfectly sunny day can be windy close to the coast. 

Does Wind Affect Boat Trips?

Yes, it can. Winds affect waves and the feeling of a boat ride, particularly on more exposed routes. So a marine forecast may be more valuable than a mere rain check, as mentioned.

Before heading out, pay attention to:

• Wind speed

• Wave height

• Local currents

• Thunderstorm risk

• Route exposure

• Advice from the captain or operator

The difference between a quiet morning and a breezy afternoon is much more pronounced on the water than is the difference between an average over the month. 

5. Sea Conditions Are Important for June Boat Trips

Zanzibar weather June is mostly suitable for boat activity with reduced rainfall and increased sunshine, however, you must check the weather conditions on the sea. You can explore Zanzibar boat tours from Kendwa, Nungwi, Stone Town and involve snorkeling, dhow trips, catamarans, excursions to the islands and fishing. 

Zanzibar offers a variety of primary experiences, including snorkeling at Mnemba, exploring Prison Island, visiting Nakupenda Sandbank, enjoying sunset dhow cruises, private catamarans, and fishing charters. 

Best Boat Trips in Zanzibar in June

If sea conditions are favorable, you can choose from a variety of options. 

• If you're looking for a shorter evening experience, then a private Kendwa beach sunset dhow cruise might be a good fit.

• If you want more deck space and a more relaxed private outing then a private catamaran cruise is considered.

• For those who want more adventure, a Zanzibar deep sea fishing charter can be considered.

You can also explore all our tours in Zanzibar and experience comparisons to fit your schedule if you are staying around the north coast.

The best plan is to have some flexibility in your travel plans. If a specific boat tour is one of the primary reasons for traveling, don't wait until the end of your trip. 

6. Snorkeling Conditions Can Be Good but Still Vary

June may be a good month for snorkeling due to the reduced amount of rain and more predictable outdoor conditions compared to the long rainy season. However, the visibility is not only dependent on sunshine.

The clarity of water around the reef can be influenced by wind, waves, currents, timing of tides and recent rainfall. This is how a snorkeling day can be very different on two occasions in the same month.

For a closer look at the main reef areas, read the guide to Best snorkeling in Zanzibar. It covers reef areas such as Mnemba, Tumbatu, and Kendwa and what the reef conditions are like in each of these areas in accordance with location, season, and tide. 

Is Mnemba Good for Snorkeling in June?

One of the most popular snorkeling areas on Zanzibar, Mnemba is a good spot in June when the sea is quiet. Zanzibar all inclusive shared catamaran is an alternative package for those who prefer to spend time around the Mnemba area with a sailing holiday.

If you are planning to go snorkeling in Zanzibar, be sure to check the visibility near the departure rather than depending on a June morning's visibility. 

Is the Water Warm Enough?

Yes. However, the sea temperatures on Zanzibar are never cold, so other factors like wind, waves and visibility are more important.

That's why June is a great time to visit for all those who enjoy swimming, snorkeling, beaches, and boat rides all in the same vacation. 

7. June Is a Great Time for Outdoor Activities and Sightseeing in Zanzibar

The simple fact that you can mix water sports with time on land is one of the best aspects of Zanzibar Weather June. When planning the most exciting Zanzibar activities, June offers a wide choice of activities but doesn't require an entire vacation of indoor fun.

• Take some time to visit Kendwa and Nungwi: The north coast is very beach-friendly, perfect for snorkeling, sunset watching, and trips to the beach. If you are staying in this part of the island, you can compare Kendwa & Nungwi private tours.

• Stone Town: Stroll through historic streets, markets, architectural landmarks and the waterfront. You can explore the Stone town tour or Stone town private tour and compare the various tours.

• Consider a spice farm tour: With less rain in June, outdoor cultural events may be easier to plan. Visit spice farms to see cloves, cinnamon, vanilla, and other plants associated with the history of Zanzibar.

• Hike in Jozani Forest: Jozani is a good option for those who want to step away from the beach! It's a different side of the island, the forest, and it's known for its Zanzibar red colobus monkey.

• Be flexible: If you are not sure what to do Zanzibar when the wind is stronger than anticipated, opt for Stone Town, a spice farm, Jozani Forest, restaurants, local markets, or a day at those places.
