May weather forecast
Biro, Benin

The wet season continues in May as the humidity and rainfall peak for the first half of the year. Changes from April are seen in the slight decrease in temperature and the cloud% increase. It creates a cooler climate than the previous month. The lack of clear sky limits direct sunlight, as indicated by the shortened sunlight hours. Winds are high during this period, blowing any fallen rain away rather quickly, but the pressure increases slightly, making the air feel heavier.

Temperature

Biro starts May with an average high-temperature of a still fiery hot 35.3°C (95.5°F), hinting at a minimal fluctuation from April. During May, Biro experiences an average low-temperature of 24.2°C (75.6°F) at night.

Heat index

May's mean heat index is estimated at a burning hot 49°C (120.2°F). Be on the lookout: Heat cramps and heat exhaustion are anticipated. Continued exertion can result in heatstroke.
Understand that the heat index values take into account shaded locations and mild winds. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', binds temperature metrics with humidity values to give a sense of the actual warmth. 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. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
