Imagine descending into the vibrant waters near Ametatu, where Tanzania's rich marine tapestry unfolds. Diving here encompasses a wide array of experiences, from exhilarating drift dives along deep walls to serene explorations of protected shallow coral gardens.

Sites generally extend to depths from 5 m / 16 ft up to 40 m / 140 ft, catering to divers across various certification levels.

Best Time to Dive

The optimal diving window across Tanzania's coastal and island sites, including the Ametatu region, generally runs from October through March, with March often scoring as an 'Excellent' month for diving conditions. This period typically sees air temperatures averaging 27-28°C / 81-82°F, combined with lower rainfall, ensuring more favorable surface conditions. For those keen on pelagic encounters, September and October are prime for humpback whale and sperm whale sightings, while whale sharks and manta rays are more frequently observed from October to April, peaking November to February. Conversely, the 'long rains' between April and June can lead to higher rainfall, which might affect visibility, and diving outside Chole Bay is often limited between June and September due to local winds.
