December weather forecast
Douala, Cameroon

December brings the onset of Douala's dry season with a stark dip in rainfall. The clear skies promote outdoor activities as the rain squalls of the previous months become a distant memory. However, the persistently high humidity is a reminder of Douala's typical tropical climate. Though the sea remains significant for cooling down, the chill in the water may not be completely appealing to swimmers. Unsurprisingly, December records the year’s lowest figure in terms of rainfall, featuring a mere 23mm (0.91").

Heat index

The heat index value during December is estimated at a blazing hot 45°C (113°F). Take heed: Heat exhaustion and heat cramps are anticipated. Heatstroke is a potential outcome of continuous activity.
It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a single figure representing how weather conditions feel when combining temperature and humidity. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.

Limit your exposure to direct sunlight during these hours. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim. Caution! The Sun's UV intensity grows with reflections off sand and water.
