Guinea-Bissau weather overview

The tiny country of Guinea-Bissau borders Guinea to the south and shares its tropical climate. It has a very heavy rainy season from May to November when conditions are made unpleasant by high humidity. Things look up between December and April when Harmattan desert winds bring dryer air to the interior and trade winds perk up the coast. Dry season temperatures get higher the further you go inland but tend to plummet at night.

What to pack for Guinea-Bissau weather

Take light clothing and good waterproofs for the rains and warmer attire for dry season nights inland.
