In Sonamura, India, understanding the UV Index is crucial for safeguarding your skin against harmful solar radiation. The UV Index indicates the strength of UV radiation on any given day, reflecting the risk of sunburn and long-term skin health issues. With Sonamura's hot Aw climate, residents and visitors alike face heightened exposure to UV rays, particularly during peak hours, from 10 AM to 1 PM, when levels soar to a maximum of 13. By staying informed about UV levels, you can take proactive measures to protect yourself, ensure outdoor activities remain enjoyable, and maintain healthy skin throughout the year.
The hourly UV Index data paints a vivid picture of sun exposure throughout the day. Starting early, at 7:00 AM, the UV Index is a mild 4, increasing steadily to reach its peak at 10:00 AM and 11:00 AM with a high of 13. The intensity remains significant until 12:00 PM, when it slightly dips to 12 but still demands attention. As the afternoon progresses, the index begins to decline rapidly: it drops to 9 at 1:00 PM, and by 2:00 PM, it's reduced to 6. The sun’s power wanes further to 3 at 3:00 PM, before tapering off to 1 by 4:00 PM, and eventually settling at 0 by 6:00 PM—signaling a safe reprieve from UV exposure. With these fluctuations, it’s crucial to be sun-safe during peak hours, especially between 10:00 AM and 2:00 PM.

Visitors and residents should take proactive measures during these months, prioritizing sun safety. It’s crucial to wear sunscreen, protective clothing, and seek shade, especially during midday hours.
