Best Time for Diving and Snorkeling in Zanzibar
If you’re planning a trip and wondering about the best time for diving and snorkeling in Zanzibar, the good news is, the island offers great underwater conditions for much of the year. However, two main seasons stand out for clear visibility, calm seas, and rich marine life: March and July to October.
March: Clear Waters and Warm Temperatures
March is one of the best months for underwater adventures. The sea is warm and calm, making it easy to dive or snorkel without strong currents. Visibility is often excellent, reaching up to 25 meters. You’ll see coral reefs, tropical fish, turtles, and sometimes dolphins.
July to October: Dry Weather and Calm Seas
From July to October, Zanzibar experiences dry weather and mild temperatures. The sea stays calm, especially around Mnemba Atoll, Chumbe Island, and Menai Bay. These months are perfect for both beginners and experienced divers. The water is still clear, and marine life is very active.
Avoid the Long Rains: April and May
The months of April and May bring heavy rains. These can reduce underwater visibility and make the sea choppy. Most diving centers stay closed or run limited trips. It’s better to avoid these months if snorkeling or diving is a priority.
Short Rains in November -Still Possible
November has short rains, but they don’t usually last all day. You can still snorkel and dive, especially if you’re staying near sheltered waters. Visibility might not be as good as in dry months, but marine life is still present and easy to spot.
Water Temperature and Marine Life
Zanzibar’s water temperature stays between 25–29°C (77–84°F) year-round, which makes diving and snorkeling comfortable in any season. You’ll find colorful reefs, clownfish, parrotfish, rays, turtles, and sometimes reef sharks. If you’re lucky, you might even see whale sharks passing through from October to December.
So, the best time for diving and snorkeling in Zanzibar is mainly during March and July to October. These months give you the best chance to enjoy calm waters, high visibility, and vibrant sea life. With the right timing, your underwater experience in Zanzibar can be truly unforgettable.
