Understanding the UV Index in Khalilabad, Iran is essential for safeguarding your skin and overall health against the harmful effects of ultraviolet radiation. With a semi-arid climate typical of the BSk zone, residents must be especially vigilant during peak UV exposure hours, particularly between 10 AM and 2 PM when indices soar to 12—a level that significantly increases the risk of sunburn. By staying informed about daily UV levels, you can take proactive steps to protect yourself from skin damage and ensure a safer, healthier enjoyment of the sunny days that characterize this beautiful region.
The hourly UV Index data presents a distinct pattern throughout the day, peaking at 11:00 AM and 12:00 PM with a maximum value of 12, indicating a high risk of harm from unprotected sun exposure during these hours. As the sun climbs, the UV Index escalates rapidly; starting at a mild 2 at 7:00 AM, it reaches 9 by 10:00 AM. After noon, however, the levels begin to taper off, dropping to 6 by 3:00 PM and further declining to 1 by 7:00 PM. This pattern highlights the importance of sun safety, particularly during the midday hours when UV radiation is at its strongest. Stay protected!
