May weather forecast
Iwo, Nigeria

The weather in May continues to reflect the wet season in Iwo, with high humidity and increased rainfall manifesting as key characteristics. The daylight hours start to lengthen subtly, but less sunlight reaches the ground due to the thick clouds. A remarkable feature of this month's climate is the amount of rainfall, peaking at 100mm (3.94"). The decrease in sunshine and the increased cloud cover engender cooler temperatures. In spite of these conditions, the wind continues its moderating influence, with gusts reaching up to 9.5km/h (5.9mph).

Temperature

A minor adjustment in Iwo's average high-temperature is noted with the start of May, touching a still tropical 33.3°C (91.9°F) from April's 34.9°C (94.8°F). Throughout May, an average low-temperature of 23.2°C (73.8°F) is experienced.

Heat index

The heat index value during May is estimated at a burning hot 49°C (120.2°F). Warning: Heat cramps and heat exhaustion are anticipated. Heatstroke is a risk with ongoing activity.
Research indicates the heat index considers values in shaded locales and with light winds. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. 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 are quite important for babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Take precautions and adopt sun safety practices. Protection against sunburn is obliged. Avoid direct sunlight between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Keep in mind that shade structures may not provide complete protection. To mitigate harm from sun exposure, pick sunglasses offering UVA and UVB defense.
