January weather forecast
Ilesa, Nigeria

Starting off the year, the weather in January in Ilesa, Nigeria shows a modest mix of sun and rain, with slightly cooler temperatures when compared to the approaching months. Clear skies persist most of the day, promoting ample hours of sunshine in conjunction with relatively low humidity, rendering the month quite pleasant. The weather subtly prepares itself for the increase in temperatures and humidity seen in later months. Levels of rainfall are at their lowest, with precipitation recorded only at 6mm (0.24"). The unassuming wind speeds and relatively clear visibility also mark this month, contributing to its overall mild conditions.

Heat index

The heat index in January is evaluated at a blistering 43°C (109.4°F). Take note: Heat exhaustion and heat cramps are expected. Heatstroke can occur with prolonged effort.
Consider that heat index readings are for situations in the shade and light wind. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', arises from combining readings of air temperature and relative moisture content. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including 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 quite important for children. 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.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.

Humidity

With an average relative humidity of 46%, January is the least humid month in Ilesa, Nigeria.

Refrain from overexposure. Fair-skinned individuals could burn in under 20 minutes. Limit your direct sun exposure, especially between 10 a.m. and 4 p.m., when UV radiation is strongest. Shade structures might not provide complete sun protection. Safeguard your eyes, ears, and face from sun rays with the aid of a wide-brim hat.
