Guinea Bissau offers pristine beaches, unique wildlife, and the stunning Bijagos Archipelago. This West African gem features 88 islands, saltwater hippos, and vibrant Creole culture, making it one of Africa's most untouched destinations.
Guinea Bissau has a tropical savanna climate with two distinct seasons: a dry season from November to May dominated by the hot, dusty Harmattan wind blowing from the Sahara, and a rainy season from June to October when the southwest monsoon brings heavy downpours. Temperatures remain warm year-round, ranging from 24°C at night to 35-40°C at the peak of the dry season. Coastal and island areas benefit from Atlantic breezes that moderate the heat significantly, while the interior experiences more extreme temperatures.
