Zanzibar is a semi-autonomous archipelago off the coast of Tanzania, known for its white sand beaches, historic Stone Town, and spice plantations. However, there are certain times of the year that are less ideal for visiting this tropical paradise. Here is an overview of the worst times to visit Zanzibar and what to expect during these periods.
April and May – Long Rains
The Long Rains in Zanzibar typically last from March through May. April and May are often the wettest, most humid, and hottest months of the year. During this period, expect heavy downpours almost daily, high temperatures and humidity, and potential flooding in low-lying areas.
While nature flourishes thanks to the increased precipitation, this is considered one of the worst times for beachgoers or those who want to stay dry on their holiday. Many attractions may have reduced hours and some lodging options or restaurants may even temporarily close. You’ll also have to contend with lots of mud, flooded roads, and swarms of mosquitoes.
June to September – Cooler and Windy
The cooler, windier, and drier season comes between June and mid-October. While June through August offer a break from the oppressive heat and humidity, this period is still quite windy and cool for a tropical destination like Zanzibar. Overcast skies are common and the ocean waters are colder for swimming.
If you don’t mind dressing warmer and dealing with blustery winds, discounts on hotels make this low season a good value. But you won’t get the full experience offered during more pleasant weather. Expect intermittent rain showers as well.
Mid-December to Mid-January – Peak Holiday Crowds
The busiest tourist season in Zanzibar aligns with the holidays in December and January. Prices for flights and hotels skyrocket due to peak demand. So you’ll get lovely hot weather but pay a premium and battle immense crowds everywhere – on the beaches, in Stone Town, and at all the famous attractions.
Don’t expect a peaceful or authentic island experience during these weeks. Roads are congested, popular excursions and facilities see extremely long wait times, and budget options may be sold out months in advance. Noise and neon lights dominate compared to the normally laidback Zanzibari atmosphere.
March to May – Risk of Tropical Cyclones
As Zanzibar falls inside the Southwest Indian Ocean tropical cyclone basin, there is an annual cyclone season that peaks in April and May. Powerful storms have struck the islands during these months, most notably Cyclone Kenneth in 2019.
Visiting Zanzibar from March through early June puts you at risk of canceled flights, damage to infrastructure, flooded accommodations, washed out roads, dangerous surf and wind conditions, and other vacation ruining impacts. Monitor storm forecasting reports closely before and during your trip.
Ramadan (Variable Date)
The holy month of Ramadan is widely observed in predominantly Muslim Zanzibar. As the dates shift annually, it’s important to check the calendar before you travel. Ramadan brings major changes like shortened business hours, lack of food or drink during daylight, and other religious considerations.
While witnessing Ramadan traditions can be an cultural experience for visitors, it may impact your ability to dine out stress-free or find entertainment. Additionally, closures around Eid Al-Fitr festivities afterwards can create further disruptions to your schedule.
The Bottom Line
If perfect beach weather, minimal crowds, open attractions, and lively nightlife are priorities for your vacation, it’s best to avoid visiting Zanzibar during the rainiest, coldest, busiest, or stormiest stretches of the year. For reliable warm and sunny conditions paired with low-season discounts, target June or September through November instead. Or properly prepare if scheduling limitations land you in Zanzibar during its trickier weather seasons.
