Bissau experiences a tropical climate with two distinct seasons: a dry season from November to May and a wet season from June to October. The dry season is characterized by hot temperatures reaching the mid-90s°F with virtually no rainfall, while the wet season brings slightly cooler temperatures in the upper 80s°F but substantial precipitation, particularly from July to September when monthly rainfall exceeds 14 inches. The city maintains consistent humidity levels around 70% year-round, with the Atlantic Ocean providing some moderating influence on temperatures. The climate pattern shows the hottest and driest conditions from February to April, making this period ideal for beach activities but potentially challenging for extensive outdoor exploration. The rainy season transforms the landscape but can significantly impact transportation and outdoor activities, with August receiving the heaviest rainfall at 18.4 inches. The shoulder months of May, June, October, and November offer transitional conditions that can be favorable for various activities.
