The climate of Grand-Bassam
Grand-Bassam rests within the geographical scope of the Am zone of the Köppen climate classification. This particular category designates a tropical monsoon climate, known for high humidity levels and substantial rainfall, especially during the rainy season.

With average high temperatures ranging from 26°C (78.8°F) in August to 30.4°C (86.7°F) in April, the atmosphere can get quite hot. Correspondingly, the mercury level during the cooler months falls slightly, with lows recorded between 23.4°C (74.1°F) in August and 26.8°C (80.2°F) in April.
