April weather forecast
Biro, Benin

April features a more pronounced difference from the dry season, as both temperature and humidity levels continue to rise. The increase in cloud% from the previous month indicates that the sky is less clear and the sunshine less bright. Rainfall reaches an average volume of 60mm (2.36") for the month, combining with the high humidity to create a typically wet month. Winds become stronger during this period, offering some respite from the humid condition. Even though the days are generally cloudy, the UV index remains high, requiring continued use of sun protection.

Temperature

The arrival of April in Biro marks a slight shift to an average high-temperature of a still torrid 37.8°C (100°F) from March's 39.2°C (102.6°F). Contrary to the day's heat, an average low-temperature of 24.8°C (76.6°F) is recorded during the nights in April in Biro, Benin.

Heat index

The heat index value during April is estimated at a life-threatening hot 50°C (122°F). Attention: Heat exhaustion and heat cramps are quite likely. Heatstroke becomes a risk with continued exertion.
Metrics for the heat index primarily focus on shaded spots and light wind conditions. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', reflects the feeling of heat when considering both air temperature and humidity. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

Stay protected; otherwise, skin and eyes can suffer rapid damage. Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. Select sunglasses that boast both UVA and UVB protection to limit the adverse effects of the sun on the eyes.
