April weather forecast
Ilesa, Nigeria

April sees the weather in Ilesa fully embracing the rainy season, hallmarked by significant leaps in rainfall and humidity levels. The atmosphere becomes rich in moisture, thereby decreasing visibility and keeping the skies densely clouded. Despite this, generous daylight hours persist, ensuring the presence of the sun is still felt during the day. The clearest shift is seen in the rainfall, soaring to a hearty 73mm (2.87"). The rain takes the stage, setting the rhythm for this month and further contributing to the cooler yet humid environment now typical of Ilesa.

Heat index

The heat index value for April is evaluated at a burning hot 52°C (125.6°F). Stay on guard: Heat exhaustion and heat cramps are predicted. Ongoing effort can cause heatstroke.
When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a measure of how hot it feels when the actual air humidity is factored in. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. With excessive moisture in the atmosphere, the effectiveness of the evaporation process is decreased, causing the body to cool down less efficiently, leading to a sensation of overheating. As body temperatures escalate without effective heat release, one might face dehydration threats.

Guard oneself from overexposure. Defence against sun injury is vital. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. In bright sunlight, prioritize sunglasses that grant protection from UVA and UVB radiation.
