In Iyana-Ofa, Nigeria, awareness of the UV Index is crucial for safeguarding against the harmful effects of ultraviolet rays. Understanding UV levels helps residents and visitors alike take proactive measures to prevent sunburn and maintain long-term skin health. Given Iyana-Ofa's tropical climate, where UV exposure can peak significantly throughout the day, it's essential to stay informed about these levels. With peak UV Index readings reaching as high as 12 around noon, ensuring proper protection from the sun is key to enjoying the beautiful outdoors while minimizing health risks.
The UV Index provides a compelling insight into daily sun exposure, with a noticeable rise as the day progresses.

It’s essential to take precautions during the midday hours to shield against the sun’s rays!

Throughout the year, seasonal UV changes reveal high levels of ultraviolet radiation, particularly from January to October, when the UV Index consistently stays in the extreme range, peaking at 14 in April. Notably, the high-risk months are from February to October, where the burn time sharply decreases to 10 minutes, posing significant risks for skin damage. As UV levels rise during these months, it is crucial for both visitors and residents to take protective measures: use sunscreen, wear protective clothing, and seek shade during peak sun hours.

Being mindful of these conditions is essential for safe outdoor activities year-round.
