Understanding the UV Index is crucial for the residents of Dhanbad, India, where sun exposure is a significant health concern due to its Cwa climate. With daily UV levels often peaking around 11 during midday, awareness of these fluctuations can help you take necessary precautions to prevent sunburn and protect your skin health. As the intensity of UV radiation can lead to both immediate effects, like sunburn, and long-term issues, including skin cancer, knowing the UV Index empowers you to enjoy the sun safely. Be mindful of the typical risks associated with Dhanbad’s prevalent sunshine, especially from late morning to early afternoon when UV exposure can be most intense.
The UV Index for the day tells an interesting story of solar intensity. Early risers at 7:00 AM will find a moderate UV Index of 3, which climbs steadily to 6 by 8:00 AM. As the clock strikes 9:00 AM, the index reaches a lively 9, and by 10:00 AM, it surges to a peak of 11. The intensity peaks further, hitting a scorching 12 at 11:00 AM, before gradually descending to 11 again at 12:00 PM. The afternoon sees the UV Index waning, first dropping to 9 at 1:00 PM, then to 6 at 2:00 PM, and continuing down to 4 by 3:00 PM. By the time the sun sets at 6:00 PM, the UV Index diminishes to a safe 0, offering a perfect evening for outdoor activities without the worry of sun exposure. Plan your day wisely to enjoy the sunshine while keeping skin safety in mind!
