Diving in Tanzania

Quick facts

  • Liveaboards are a must for any diver seriously wanting to explore the sites around Pemba Island.
  • The seas can be unpredictable in the Pemba Channel affecting visibility.
  • If you are unfit, not a strong swimmer or not confident about diving in 4 knot currents, think twice before getting in Pemba's eastern waters.
  • Malaria risk exists throughout the year in the whole country below 1800m. Prevention recommended.
  • BE AWARE: Lariam (mefloquine) is an anti-malarial drug used in regions of the world where chloroquine resistant falciparum malaria is prevalent. e.g. East Africa, South East Asia. Possible side effects of lariam such as dizziness, blurred vision and a disturbed sense of balance are common and could cause problems for divers. These effects can often imitate or even worsen the symptoms of DCI. There could also be confusion between the side effects of lariam and the symptoms of DCI or nitrogen narcosis resulting in a misleading diagnosis.
  • Inoculations: Typhoid, hepatitis A, diphtheria, yellow fever. Take advice before travelling.
