Understanding the UV Index is crucial for residents and visitors in Kari, Nigeria, where the warm BSh climate presents unique challenges related to sun exposure.

By staying informed about UV fluctuations throughout the day, you can take proactive steps to protect yourself against the harmful effects of ultraviolet radiation typical in this region, ensuring a safe and enjoyable experience under the sun.
The UV Index throughout the day presents an interesting pattern as the sun rises and reaches its peak intensity. Starting at a mere 1 at 7:00 AM, it climbs slowly, hitting 2 by 8:00 AM.

As the afternoon rolls on, the index begins to wane, dropping to 9 at 2:00 PM and then steadily declining to 3 by 4:00 PM. Finally, the UV exposure diminishes significantly as the day winds down, returning to a safe 1 by 7:00 PM and 0 by 8:00 PM. Be sure to enjoy the sun wisely!

The months of March through October consistently have an extreme exposure category, with UV Index values peaking at 13 in July, August, and September.
