The best time to visit Zanzibar for a beach holiday is during the dry months of June to October and from December to February. June to October is cooler and drier, with a steady breeze and the clearest water. December to February is hotter and more humid but still mostly dry. The rains come in two seasons, from March to May and in November, and they bring heavy showers, lower prices and a quieter island.
Which month suits you also depends on which coast you choose, because the tides and winds differ between the north and the east. This guide goes through each season and then helps you pick a beach to match.
How Does Zanzibar's Climate Work?
Zanzibar lies a few degrees south of the equator, so temperatures stay warm all year, with sea temperatures around 26 to 30 degrees Celsius. The seasons are shaped by the monsoon winds. From roughly December to March, a warm wind blows from the north-east, making the island hot and humid. From June to October, a cooler wind blows from the south-west, giving drier and more comfortable weather. Between them come the rainy seasons, when the wind changes direction.
The long rains from March to May are the heaviest, with storms that can last for days. The short rains in November are lighter, often arriving as afternoon showers. Even in the wet months, the sun appears for part of most days, but the weather is less predictable.
Which Months Are Best for the Beach?
June to October: the best all-round window
These months have the driest, clearest weather and a cooling breeze. The sea is calm on most beaches, visibility for snorkelling is good, and the nights are comfortable. It is the busiest period, with the highest prices in July, August and the Christmas period close behind. Book accommodation early, particularly if you are pairing the island with a safari in the Serengeti during the Great Migration.
December to February: hot, bright and busy
The island is at its hottest, with strong sun and warm water. Showers happen, usually short, and the days are long and bright. Christmas and New Year are expensive and booked well ahead. January and February are quieter once the holidays end. Bring sun protection and plan activities for the morning and late afternoon.
March to May: the long rains
These are the wettest months. Rain can be heavy, some resorts close and activities are cancelled when the sea is rough. The upside is low prices, very few visitors and green scenery. If you accept the risk of rain, April and May can be restful. Many travellers avoid them.
November: the short rains
November is unpredictable but usually warm, with showers and sunshine in turn. It is a shoulder month with good rates and a calm island. It suits travellers who can accept variable weather.
Does the Coast You Choose Change the Best Time?
Yes. The north coast, around Nungwi and Kendwa, has beaches that stay swimmable through the tide cycle, so the water remains deep enough for a swim at low tide. The east coast, around Paje, Jambiani and Matemwe, has a wide reef and a large tidal range, so at low tide the water goes out a long way and you walk across sand and seaweed flats. Swimming on the east coast depends on the tide timetable.
The east coast is also windy at certain times, which makes Paje a world-class kitesurfing spot. If you want calm swimming at every hour, choose the north. If you want kitesurfing, choose the east in the windy months. Read how to visit Zanzibar for the beaches and the practical details.
What Else Should You Do While You Are There?
A beach holiday on Zanzibar is easy to enrich with a few outings. Stone Town, a UNESCO World Heritage Site, offers winding streets, markets and old merchant houses. A spice farm visit shows how cloves, vanilla and cinnamon are grown. Jozani Forest is home to the rare red colobus monkey. Snorkelling or a dhow trip to a reef gives you the water at its best. Read what Zanzibar is famous for for a full list.
The best time for these outings follows the same pattern: dry months are easiest, and rainy months need flexibility.
How Do You Pair Zanzibar With a Safari?
The island is a natural finish for a safari. Fly from Arusha, Kilimanjaro or a Serengeti airstrip to Zanzibar, and rest after the early starts and dusty tracks. The dry months align with the best months for the Serengeti, so the pair works well from June to October and from January to February. In the rains, the safari still goes ahead, but the beach is less predictable.
For ready-made trips, see the 10-day Tanzania safari and Zanzibar beach holiday, the 12-day Tanzania safari and Zanzibar and the 14-day Great Migration safari with Zanzibar. Read how much a Serengeti safari and Zanzibar holiday costs for the budget.
What Should You Know About Ramadan and Local Customs?
Zanzibar is mostly Muslim, and the culture is relaxed and welcoming. During Ramadan, some restaurants and shops outside tourist areas close during the day, and visitors are asked to dress modestly and avoid eating or drinking in public away from resorts. Resorts continue to operate normally. Ramadan moves each year, so check the dates if you plan to travel. In Stone Town and villages, cover your shoulders and knees. On resort beaches, swimwear is fine.
How Hot and Humid Does It Get?
Zanzibar is hot all year, and the feel changes with the season. From June to October, daytime temperatures are around the high twenties Celsius, with low humidity and a cooling breeze. December to March is hotter and stickier, with temperatures in the low thirties and humidity that makes midday uncomfortable. The long rains cool the air but add heavy humidity. Most resorts have air conditioning, shaded terraces and pools, and the sea is always warm. Plan active outings for the morning and late afternoon in the hotter months.
What Is the Sea Like Through the Year?
The sea is warm and clear in the dry months, with the best visibility for snorkelling and diving from about June to March, subject to the weather. In the long rains, the water can be cloudy and rough, and boat trips are sometimes cancelled. On the east coast, the tide pulls the water far out, so plan swimming around the tide table. On the north coast, you can swim at most times. Always follow the advice of your hotel or guide about currents and local conditions.
Which Activities Suit Which Months?
Kitesurfing is best in the windy months, roughly July to September and January to February, on the east coast. Snorkelling and diving are best in clear water. Spice tours, Stone Town walks and visits to Jozani Forest work all year, though rain can interrupt them. Dhow trips and sunset cruises are best in the dry months. A quiet beach holiday suits any time that the weather is good. If you want to combine activities with rest, choose a base with a pool and easy access to the sea.
How Do School Holidays and Festivals Change Prices?
Prices rise in the peak weeks: July and August, the Christmas and New Year period and the Easter holiday. Book accommodation early for those dates. Local festivals, such as the Mwaka Kogwa celebration in July in Makunduchi, add colour but also visitors. The month of Ramadan changes the rhythm of the town, as shops and restaurants adjust, though resorts operate normally. Check the dates if you plan a visit and want to avoid or see these events.
