In Scituate, United States, understanding the UV Index is crucial for protecting your skin and overall health. With the coastal Cfa climate that ushers in both sunny days and high UV exposure, being aware of daily UV levels can make a significant difference in preventing sunburn and long-term skin damage. During peak hours, especially between 10 AM and 2 PM, UV Index ratings can soar to levels 10 and 8, indicating a heightened risk for skin injury. Stay informed and take the necessary precautions to enjoy the sun safely!
As the sun rises, the UV Index begins to climb, starting at a modest 1 by 7:00 AM. By 8:00 AM, it has tripled, reaching 3, and continues its ascent to 4 at 9:00 AM. The peak intensity hits between 12:00 PM and 1:00 PM, where the UV Index soars to an intense 10—an indication of strong sun exposure. The afternoon sees a gradual decline, with values of 9 at 2:00 PM and 7 by 3:00 PM, showing that even later in the day, caution is advised. As the sun begins to set, the UV Index drops back down to 1 by 6:00 PM, making the daylight hours the most critical for sun protection. Stay safe and smart under the sun!
