Residents woke up to a thin blanket of white covering the ground, trees, and roofs, creating an ethereal winter wonderland. The snowfall lasted for several hours before melting away, leaving behind a sense of awe and wonder.

Scientific Explanation

While snowfall in equatorial regions is uncommon, certain weather conditions can make it possible. Iseyin’s snowfall was attributed to a combination of factors, including a cold front from the north, low atmospheric pressure, and high humidity. The cold front brought frigid temperatures to the area, while the low pressure system created a zone of instability. The high humidity ensured that there was sufficient moisture in the air for snow crystals to form. As the cold air met the warm, humid air from the ground, the moisture condensed and froze into snowflakes.

Sunrise and Sunset Times

In Iseyin, Nigeria, the time of sunrise and sunset varies throughout the year due to the Earth’s tilt and rotation. During the summer solstice, around June 21st, the sun rises earliest at approximately 5:55 AM, providing longer daylight hours. Conversely, during the winter solstice, around December 21st, the sun rises latest at around 6:44 AM, resulting in shorter days.

Sun Intensity and UV Index

Iseyin, Nigeria, experiences high levels of solar intensity and UV radiation due to its location close to the equator. The sun’s intensity peaks around noon each day, reaching its maximum level during the dry season (November to March). During these months, the UV index can exceed 10, indicating a very high risk of sunburn and skin damage. Protective measures, such as wearing sunscreen and avoiding prolonged exposure to the sun during peak hours, are essential for staying safe.

Moon Characteristics in Iseyin
