Understanding the UV Index is crucial for residents and visitors of Dera Nanak, India, as it directly impacts our skin health and sunburn prevention. With the region's Cwa climate, which typically features hot summers, awareness of UV levels becomes even more vital to plan outdoor activities safely. During peak hours, particularly between 11:00 AM and 1:00 PM, the UV Index can soar to dangerous levels (11), highlighting the need for protective measures. By staying informed about the daily UV trends, you can enjoy the sun while effectively safeguarding your skin from harmful ultraviolet rays.
The UV Index throughout the day showcases a clear rise and fall in sunlight intensity. Starting at a mild 2 at 07:00, the index gains momentum as the sun climbs higher, peaking at an intense 11 by 11:00 and staying strong till 12:00. From there, it gracefully tapers off, descending to 8 at 14:00, and dropping steadily to a gentle 1 by 18:00. Finally, as evening sets in, the UV Index plummets to 0 by 19:00. It's a vivid reminder to stay protected during those peak hours when the sun is at its strongest!

As the seasons change, so does the UV Index, which significantly affects sun exposure risks. January and February present moderate UV levels (4-5), suggesting a burn time of 30 minutes. However, as spring approaches, March and April see a sharp increase to a very high UV Index of 9, reducing safe sun exposure to just 15 minutes. The summer months of May, July, and August elevate UV levels to an extreme Index of 11, with minimum safe exposure dropping to 10 minutes—the highest risk period of the year. June maintains a very high level of 10, while September starts a gradual decline to 8. By October, the UV Index lowers to 7 but still warrants caution with a 25-minute burn time. The year closes with moderate levels again in November and December, reminding us to remain vigilant as UV radiation can still pose risks. Visitors and residents are advised to wear sunscreen, protective clothing, and seek shade during the highest UV Index days, particularly from late spring through summer.
