Brazzaville sits just south of the equator with a tropical wet and dry climate that keeps temperatures consistently warm year-round.

The city experiences a pronounced dry season from June to September and a long wet season from October to May, with the heaviest rains falling between March and May.

Temperatures hover between 22°C and 31°C throughout the year, with minimal seasonal variation but noticeable drops during the dry season nights.

Humidity remains high even during the dry months, creating a persistently sticky atmosphere that makes breathable fabrics non-negotiable.

The city's position along the Congo River adds an extra layer of moisture to the air, meaning quick-dry materials prove far more practical than cotton.
