Understanding the UV Index is crucial for residents of Nahan, India, as it plays a significant role in sunburn prevention and overall skin health. With varying UV levels throughout the day, knowing when to protect yourself from harmful rays is essential, especially in a Cwa climate like Nahan's, where sunny days can lead to increased exposure risks. During peak hours, notably between 10:00 AM and 12:00 PM, the UV Index can soar to 10, indicating a very high risk of harm from unprotected sun exposure. By staying informed about local UV levels, you can enjoy the sunny weather while safeguarding your skin from damage.
The UV Index paints a vivid picture of the sun’s intensity throughout the day. At sunrise (07:00), the index starts modestly at 2, but by 08:00, it rises to a comfortable 4. The sun gains strength, with readings escalating to 6 by 09:00. The peak arrives at 11:00 and 12:00, where the index reaches a striking 10—a clear signal to seek shade or apply sunscreen! As the afternoon progresses, we see a decline; the UV Index drops to 9 at 13:00 and gradually decreases to 5 by 15:00. The late afternoon brings a gentle taper off to 3 by 16:00, before plummeting to 1 by 17:00 and finally settling at 0 as evening descends (19:00). Stay sun-smart and enjoy the daylight safely!

As the seasons change, so does the UV Index, reflecting significant variations in sun exposure risk. January starts with a moderate UV Index of 5, but by February, it climbs to 6, indicating high risk, with reduced burn times.
