What Is the Weather Like in Cotonou?

Cotonou has a warm climate all year, so the main difference between months is not cold versus warm. The real question is rain, humidity, storms, cloud cover, and how heavy the air feels during the wettest part of the year. The Cotonou climate by month shows average highs from about 81F (27C) in the coolest part of the year to about 88F (31C) in the hottest part. Annual precipitation averages roughly 52.1 inches.

Weather in Cotonou changes the feel of the city because this is a place where comfort depends on more than the number on a forecast. A mild month can make metro transfers, neighborhood walks, outdoor meals, and photography feel easy. A difficult month can make the same itinerary feel slower, sweatier, colder, wetter, or more dependent on indoor breaks.

What makes August stand out is balance. It is not necessarily perfect every day, but it usually gives travelers the best combination of outdoor comfort, manageable weather risk, and enough flexibility for a first-time trip. If hotel prices or crowds rise during this period, that popularity is at least partly weather-driven.

Rain is the main problem. The month is not impossible, but showers and damp conditions can interrupt outdoor plans and make transit transfers less pleasant.
