January
January marks the beginning of the hot season with humid weather but is occasionally visited by north-eastern ‘kaskazi’ winds. On average, the temperature ranges from 78.8°F (26°C) to 86°F (30°C). The weather is optimal for exploring the azure waters of Zanzibar, particularly the coral gardens of Chole Bay because of clear visibility. This is the peak time for thrilling encounters with whale sharks off Mafia Island. It’s also the mango season and the end of Pemba’s clove harvest. Some popular attractions during this time include Chumbe, Paje, Prison Island, Kiwengwa, Kendwa, and Ras Kizimkazi.
February
In February, the ‘kaskazi’ winds slowly diminish with temperatures typically ranging from 78.8°F (26°C) to 86°F (30°C). It’s one of the hottest and driest months but popular for beach holidays. Kendwa boasts a broad, protected beach perfect for sunbathing and swimming. It is also an opportune time to swim with dolphins at Ras Kizimkazi.
February is hatching season for the giant Aldabran Tortoise colony at Prison Island—here lies a 190-year-old tortoise, considered globally one of the oldest living animals. The ‘Sauti za Busara Music Festival’ is a four-day celebration of East-African music at Stone Town’s Old Fort that takes place around this time.
March
March initiates the pineapple and main rainy season. It has the most unpredictable weather, making it the least popular time to visit Zanzibar, Tanzania. While the first half may be favorable, heavy downpours are anticipated by mid-March, discouraging wind sports. Despite the variability, a good day allows for snorkeling, diving, or enjoying sunsets of pink and purple hues.
March also coincides with Ramadan, the holy month of fasting where respect for religious customs is essential. Zanzibar being predominantly Muslim, is met with shorter working hours with an emphasis on spiritual activities. While most beach resorts operate, elsewhere you may find eateries and shops shut early in the day, but by evening they resume once the fast is broken. As Ramadan etiquette, appropriate clothing should be worn. Public eating and drinking are discouraged during this time and Non-Muslims are expected to refrain from entering Mosques unless specifically invited.
April
April is the wettest month and marks the peak of the main rainy season. The month poses a unique charm but the wavering weather conditions make it difficult to plan your activities. This time witnesses a mix of intense showers and warm temperatures that soar above 86°F (30°C). The mornings are often tranquil with warm seas around 82.4°F (28°C) but may be accompanied by short and fierce afternoon storms. Based on which side of the coast you’re at, you can have a glimpse of spectacular sunrises and sunsets.
This month is the quietest and landscapes appear to be lush and verdant, which may be appealing to nature lovers. It’s also the time to witness one of the biggest bird migrations in the country.
May
The main monsoon downpours persist until May but generally subside towards the month’s end, summoning increased periods of sunshine. This marks the end of the rainy season with average daytime temperatures around 86°F (30°C). The ‘kusi’ wind is more prominent during this month providing a more pleasant atmosphere during the weather transition. Being a quieter month, crowds tend to be typically less, and culture enthusiasts can engage with local communities intimately. Even though there are heavy downpours throughout May, you can still encounter pleasant days for beach activities and exploration by the end of the month.
June
The onset of the long dry season is in June, making it the sunniest and driest month of the year. This period sees low humidity with comfortable temperatures at an average of 82°F (28°C) in the daytime. The southern ‘kusi’ wind is in full force during this time, providing optimal conditions for wind sports, especially kitesurfing in places like Paje. If you’re seeking relaxation away from strong winds, northern resorts are a more tranquil setting for beachside activities. A major highlight in June is the beginning of the turtle hatching season and being able to witness this phenomenon around Mafia Island.
July
July is generally dry, warm, and low in humidity making it one of the best times to visit Zanzibar, Tanzania. The daytime temperature averages around 82.4°F (28°C) and nighttime lows seldom drop below 64.4°F (18°C). In July the southern ‘kusi’ winds peak and it is the windiest month posing ideal conditions for kitesurfing and wind-based water sports along the eastern coast, specifically in Paje. While the wind may impact diving conditions, the northern reefs are usually undisturbed and calm. The seas are coldest in July and August but still pleasant for swimming, with sea temperatures around 77°F (25°C) and shallow lagoons feeling even warmer.
In July, especially on Pemba Island, the clove harvest season commences, filling the air with the aroma of drying cloves. During this month cultural festivities take center stage such as—the Festival of the Dhow Countries organized by ZIFF at Old Fort district and the Mwaka Kogwa festival at Makunduchi Village.
August
August brings the end of the cooler months in Zanzibar and daytime temperatures average around 82.4°F (28°C) but can exceed 86°F (30°C). The southern ‘kusi’ wind begins to fade by mid-August, still providing conditions for kitesurfing near places like Paje and Jambiani. During this time Nungwi and Kendwa present tranquil beach experiences. It is also the prime season for sports fishing with deep sea boat tours organized to catch Sailfish and Marlin.
While there may be blissful beach days, when it comes to off-shore sites, divers need to carefully plan due to rough conditions. This time of year, you can also experience Pemba’s clove harvest in high gear and witness turtle hatchlings on Juani Island.
September
September brings dry and sunny days, with daytime temperatures steadily climbing above 86°F (30°C). The ‘kusi’ winds ease and the seas of Zanzibar calm down by this time. It is a popular month given that the conditions are excellent for kitesurfing, deep-water dives, water sports, and wildlife experiences. September marks the start of whale shark season near Juani Island, where you can also sight turtle hatchlings.
October
During October the skies are generally clear and the seas are calm, but the heat gradually builds over the month. Daytime temperatures regularly exceed 86°F (30°C) and nights get humid and warmer with temperatures over 82.4°F (20°C). Each year the arrival of the monsoons in November is unpredictable, so you may experience heavy rainfall before October ends. Being one of the least windiest months with pleasant sunny days, the ocean has clear visibility making it great for diving across the archipelago. Zanzibar sees tourism peak in October with boutiques and smaller villas in areas like Pingwe and Matemwe offering exclusive experiences.
Since the beaches around Paje, Kiwengwa, and Nungwi tend to be crowded this time of year, you can consider quieter alternatives like Pemba and Mafia which have some of their best snorkeling and diving in October. Ras Kizimkazi is a great place to stay at this time of year where you can witness the start of the dolphin spotting season in its tranquil waters. If you’d like to experience swimming with whale sharks you can do so off Mafia Island.
November
The rains of November mark the short rains of the rainy season with the north-eastern ‘kaskazi’ winds picking up around this time. It is warm and tranquil but may see sporadic storms that may affect beach tanning. Tourism activities aren’t significantly hindered as the showers are brief. The southern seas in Zanzibar are generally calmer and suitable for dolphin-spotting boat tours. November isn’t a highly recommended month to visit, however, tourists decrease during this time resulting in a quieter, relaxed ambiance. The rains of November need not deter you—this is a good time to get attractive deals on certain accommodations. Swimming with whale sharks and going diving off Mafia Island is still possible.
December
December has a tropical climate with temperatures ranging from 80.6°F (27°C) to 86°F (30°C) and peaking to 95°F (35°C) occasionally. The north-eastern ‘kaskazi’ winds increase around this month. The former half of the month sees significant rainfall while it gets sporadic towards the end of the month. Zanzibar’s natural beauty flourishes during December which is a great time to explore wildlife, local culture, and beach activities. The ‘kaskazi’ winds result in rough seas along the northern coastline, while the southern and western seas are calmer. Activities such as kitesurfing, diving, and swimming with whale sharks can still be explored.
