Best time to visit Guinea-Bissau

Expect year-round warmth and humidity in Guinea-Bissau but avoid the rainy season, when its already poor roads become even worse.
Guinea-Bissau’s tropical climate means it’s generally hot and humid here, with its rainy season falling between June and October. Organised tours don’t run during this time, as it’s a soggy scene and the country’s already poor infrastructure is worsened by the rain. November to April is the best time to go to Guinea-Bissau, and this is when organised small group tours depart; from December to April, the country gets virtually no rain at all. There’s little fluctuation in temperature year-round here, with an average of 26°C. Between August and February, you can see nesting sea turtles on the Bijagos Archipelago.

Guinea-Bissau Travel Advice

Chelsea Duce, from our partner Native Eye, has this travel advice:
“The main draws are the Bijagos Islands and the tribal groups. The Baiotes people, for example, lead a very isolated existence and have a unique style of architecture, while in the Bijagos Islands, there are many authentic tribal traditions. Guinea-Bissau is a very interesting destination but there are only a few main sights, hence why we only spend five days there.”
