Weather in April

While residents of Douala are trying to accustom themselves with March's substantial rainfall, April splashes in with an even greater volume of precipitation. However, it's not just about the rain, as April also presents an increased level of humidity, making the air feel heavier. Despite having a consistent downpour, residents need not worry about visibility issues as it holds steady. Compared to March, April brings more humility and an additional 21mm (0.83") of rainfall, increasing to 93mm (3.66").

Heat index

April's average heat index is estimated at a burning hot 45°C (113°F). Keep alert: Heat cramps and heat exhaustion are probable. Heatstroke is a potential danger with continued physical activity.
Always consider that heat index estimations are for light winds and places in the shade. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'real feel', joins air temperature with relative humidity to produce a temperature perception for humans. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Skirt overexposure. People with light complexions might get scorched in under 20 minutes. The Sun's UV radiation is most potent between 10 a.m. and 4 p.m. Try to limit direct exposure to the Sun during this period. On days when the sun blazes, arm yourself with sunglasses that block UVA and UVB radiation. Heads up! The reflection of sand and water notably intensifies UV rays from the Sun.
