May weather forecast
Ibadan, Nigeria

May ushers in the full onset of the rainy season in Ibadan. The city experiences a further decrease in temperature, an increase in cloud cover, and a higher chance of rainfall, but fortunately, the significant weather changes do not affect visibility. The heaviest downpours are accompanied by a refreshing breeze that makes the weather quite bearable despite the high humidity. Although the month is characterized by less sunshine and an increase in cloud cover, adequate daylight hours ensure May still has a relatively bright disposition.

Temperature

With the arrival of May, Ibadan's average high-temperature registers at a hot 33.5°C, indicating a subtle variation from the previous month. Ibadan reports an average low-temperature of 23.8°C during the nights of May.

Heat index

May's average heat index is evaluated at a burning hot 50°C. Be prepared: Heat cramps and heat exhaustion are probable. Continued activity may lead to heatstroke.
Remember that heat index calculations are made for conditions in the shade with light wind. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

Humidity

In May, the average relative humidity is 79%.

Note: An average UV index of 7 in May transforms into this advice:
Uphold preventive measures and conform to sun safety guidelines. Defending against skin and eye harm is crucial. Be aware that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. and try to reduce direct sun exposure during this period as much as possible. For holistic sun protection encompassing the eyes, ears, face, and neck, a wide-brim hat is key.
