Climate and Average Weather in Guinea-Bissau

Blue skies mixed with bright contrasting clouds are a common image in Guinea-Bissau. During the rainy season the blue parts of the sky are often replaced by heavy clouds that can often cause heavy rainfall.

Guinea-Bissau has three seasons. The wet rainy season begins in June and after a major peak between mid-July and mid-September ends in the second half of October. Then follows the dry season where the temperature rises again slightly and precipitation is more rare. Around the end of the year the likelihood of dry desert wind increases. This dry wind carries cooler air full of dust and sand from the Sahara.

The period from mid-November to April is the best travel time to visit Guinea-Bissau. The months of November, December and January are slightly less hot than the months of February, March and April which mainly face high temperatures inland. Think of high maximums like 35 to 40 degrees Celsius (95 - 104 degrees Fahrenheit).
