A cold front from the north brought uncharacteristically low temperatures to the region. Additionally, moist air from the Atlantic Ocean condensed and formed clouds that released the snow. Residents of Mamou were left in awe as they witnessed snow falling for the first time in their lives, creating a memorable and historic moment for the town.

Climate Overview

Mamou’s climate is characterized by two distinct seasons: the wet season and the dry season. The wet season spans from May to October, bringing abundant rainfall to the region. During this time, temperatures are generally high, ranging between 25 to 35 degrees Celsius (77 to 95 degrees Fahrenheit). Humidity levels are also elevated, often reaching up to 80%. The dry season, on the other hand, runs from November to April. During this period, rainfall is scarce, and temperatures are slightly cooler, averaging around 20 to 30 degrees Celsius (68 to 86 degrees Fahrenheit).

Sun Exposure

Mamou experiences high levels of solar radiation throughout the year, with an average of 6 to 7 hours of sunshine per day. During the dry season, sun exposure is particularly intense, with the sun shining brightly for extended periods. It is important to take precautions against excessive sun exposure by wearing sunscreen, protective clothing, and hats when outdoors. Additionally, sunglasses are recommended to protect the eyes from harmful ultraviolet (UV) rays. During the wet season, while rainfall can provide some respite from the sun’s intensity, it is still advisable to be mindful of sun exposure, especially during breaks in rainfall.

Moon in Mamou, Guinea

The moon in Mamou, Guinea follows a predictable cycle of phases, ranging from a new moon to a full moon. The new moon, a time when the moon is not visible in the sky, occurs when the moon is between Earth and the sun. As the moon orbits Earth, it gradually moves away from the sun, revealing more of its illuminated surface to observers on Earth. This phase is known as the waxing crescent moon.

Waxing and Waning Moon

As the moon continues to orbit Earth, it reaches the first quarter moon phase, where half of its surface is illuminated. This is followed by the waxing gibbous moon phase, where more than half of the moon’s surface is visible. The full moon phase occurs when the moon is on the opposite side of Earth from the sun, and its entire surface is illuminated. This phase provides the brightest and most visible moon in the sky. After the full moon, the moon begins to move away from the sun again, repeating the cycle in reverse order known as the waning phases.

Humidity Trends in Mamou, Guinea

Mamou, Guinea, experiences a distinct pattern of humidity levels throughout the year. The city is located within the tropical zone and is influenced by the West African monsoon. During the wet season, which spans from May to October, humidity levels surge and frequently reach above 80%. This period is characterized by heavy rainfall and high atmospheric moisture.

In contrast, the dry season, which runs from November to April, brings significantly lower humidity levels. During this period, humidity typically ranges from 40% to 60%, creating a more arid and comfortable environment. The humidity drop is primarily due to the reduced rainfall and the influence of the dry Harmattan wind from the Sahara Desert.

Wind Patterns

Mamou, Guinea experiences a tropical monsoon climate, characterized by alternating wet and dry seasons. The region is subject to the prevailing trade winds, which blow from the northeast during the dry season (November-April) and from the southwest during the wet season (May-October).
