Zanzibar Weather in May: Is May a Good Time to Visit?
May weather in Zanzibar is warm, humid and often rainy. It falls within the island’s long rainy season, locally known as the masika. Daytime temperatures are usually around 28°C to 30°C, while nights remain warm at approximately 23°C to 25°C.
However, rain does not necessarily continue throughout the entire day. Zanzibar can experience heavy showers followed by brighter periods, although some days may remain cloudy or wet for longer. Conditions also tend to improve towards the end of May as the island approaches the drier months.

These are general climate patterns rather than a forecast for a particular year. Rainfall can vary considerably from one week to another.
Does It Rain All Day in Zanzibar in May?
It can rain heavily in May, but it does not always rain all day.
Some days bring an intense shower in the morning or afternoon followed by several hours of brighter weather. On other days, clouds and repeated showers may continue for much longer. Occasionally, Zanzibar experiences several wet days together.
Tropical rain can also be very localised. It may rain heavily in Stone Town while another part of the island remains relatively dry.
For this reason, daily weather apps are not always a perfect guide. They may display a rain symbol even when showers are expected for only part of the day.
Is May a Good Time to Visit Zanzibar?
May can be a good time to visit Zanzibar if you understand the weather and remain flexible. It is particularly suitable for travellers who prefer fewer visitors, quieter beaches and possible low-season hotel offers.
However, May may not be right for you if uninterrupted sunshine is your main priority.
May may suit you if:
-
You are comfortable with occasional or frequent rain.
-
You want a quieter Zanzibar holiday.
-
You are looking for possible low-season rates.
-
You do not mind changing your plans around the weather.
-
You would enjoy a relaxed resort stay even on a rainy day.
Consider another month if:
-
You want the best chance of clear, sunny beach days.
-
You are planning several boat-based activities.
-
You want reliable conditions for photography or outdoor events.
-
Rain would significantly affect your enjoyment of the holiday.
For more dependable dry weather, June to October is usually a better choice.
Weather in Zanzibar at the Beginning of May
The beginning of May normally falls within the heart of the long rains. Therefore, visitors should prepare for high humidity, heavy showers and periods of cloud cover.
Boat trips, snorkelling excursions and other sea activities may be postponed when rain, wind or visibility makes conditions unsuitable. It is sensible to avoid building an itinerary that depends on outdoor activities happening at fixed times.
Nevertheless, the island remains warm, and there can still be dry or sunny periods between showers.
Weather in Zanzibar at the End of May
The weather in Zanzibar at the end of May often begins moving towards the drier conditions associated with June. Rain can still occur, but showers may become less persistent as the month progresses.
This does not mean that the final week of May is guaranteed to be dry. Seasonal transitions vary from year to year. Still, travellers choosing between early and late May may find that the end of the month offers a better chance of favourable beach weather.
Weather in Zanzibar in May and June
June is generally drier and slightly cooler than May. It also marks the beginning of one of Zanzibar’s most popular travel periods.
| Conditions | May | June |
|---|---|---|
| Rainfall | Frequent; sometimes heavy | Usually much lower |
| Temperature | Warm and humid | Warm and more comfortable |
| Sunshine | Unpredictable | More dependable |
| Visitor numbers | Low | Begin to increase |
| Hotel choice | Some properties may close | Most hotels operate normally |
| Outdoor activities | May face disruption | Generally more reliable |
| Overall experience | Quiet and flexible | Better for a classic beach holiday |
If weather reliability matters more than possible savings, June is the better choice. If you prefer quieter resorts and are willing to accept some rain, May may still work.
Can You Swim in Zanzibar in May?
Yes. The sea around Zanzibar normally remains warm enough for swimming in May.
However, rain and wind can temporarily affect water clarity and sea conditions. Always follow advice from your hotel, boat operator or beach guide before swimming or joining a marine excursion.
The tides also have a major effect on swimming, particularly along the east and southeast coasts. At low tide, the ocean can retreat a considerable distance from the beach. This tidal movement occurs throughout the year and is not caused by the May rains.
Travellers who want easier access to the sea throughout the day may prefer areas such as Nungwi or Kendwa in northern Zanzibar.
Are Zanzibar Excursions Available in May?
Many Zanzibar excursions continue operating in May, but everything depends on the conditions on the day.
Possible activities include:
-
Stone Town tours
-
Spice farm visits
-
Jozani Forest tours
-
Cultural and village experiences
-
Prison Island excursions
-
Snorkelling and diving
-
Safari Blue and dhow trips
-
Restaurant and food experiences
Land-based tours are usually easier to operate around the rain. Meanwhile, boat trips may be delayed, changed or cancelled when the sea is rough.
It is best to leave some free time in your itinerary instead of booking a different sea excursion for every day.
Are Hotels Open in Zanzibar in May?
Many Zanzibar hotels remain open throughout May. However, some smaller properties use the low season for annual maintenance, staff leave or temporary closure.
Before booking, confirm:
-
That the hotel will be fully operational
-
Whether all restaurants and facilities will be open
-
If construction or maintenance is planned
-
Whether airport transfers are available
-
The cancellation and date-change conditions
Lower prices can make May attractive, but the cheapest room is not always the best value. Choose a comfortable property with good indoor spaces, reliable service and enough facilities for days when the weather limits beach activities.
Where Should You Stay in Zanzibar in May?
Your choice should depend on the experience you want rather than on the weather alone.
Nungwi and Kendwa
The north is a practical choice for visitors who want easier swimming access and a wider selection of restaurants, resorts and activities. These areas can also feel livelier than other parts of Zanzibar during the low season.
Paje and Jambiani
The southeast offers long beaches, relaxed villages and a laid-back atmosphere. However, tides are much more noticeable here. Wind and sea conditions can also affect water-based activities.
Matemwe and the northeast coast
This area is peaceful and works well for couples or travellers looking for a quiet resort stay. It is also convenient for excursions towards Mnemba, although boat trips remain weather-dependent.
Stone Town
Stone Town is a good choice for history, culture, food and architecture. A short stay here can add variety to a May holiday, particularly when the weather is not ideal for the beach.
Can You Combine a Safari With Zanzibar in May?
Yes. May can be an excellent time to combine an East African safari with a Zanzibar stay if you are comfortable travelling during the green season.
One practical itinerary is to fly into Nairobi, enjoy a Kenya safari and then fly to Zanzibar for several nights by the beach. This gives you two different experiences in one journey instead of relying entirely on beach weather.
Kenya’s parks are green during this period, and there are usually fewer safari vehicles. However, rain can affect some roads, so it is important to use an experienced local safari operator and a suitable 4×4 vehicle.
What to Pack for Zanzibar in May
Pack for warm weather, rain and humidity.

-
Lightweight, breathable clothes
-
A light waterproof jacket
-
Quick-drying footwear

Should You Book Zanzibar in May?
Book Zanzibar in May if you want a peaceful, warm and potentially better-value holiday—and you are willing to accept uncertain weather.
Avoid May if your ideal holiday requires guaranteed sunshine, calm seas and a full programme of boat excursions. In that case, June to October will usually offer more dependable conditions.
The most important point is to book the right property. A well-equipped resort can still provide a relaxing holiday when rain arrives, while an unsuitable hotel may leave you with very little to do.
