Understanding the UV Index in Inami, Japan is crucial for safeguarding your skin and overall health. With typical summer temperatures in the humid subtropical climate (Cfa) often leading to intense sun exposure, being aware of UV levels helps you prevent sunburn and reduce the long-term risks of skin damage. During peak hours, such as between 11:00 AM and 1:00 PM, the UV Index can soar to a striking 12, indicating a very high risk of harm from unprotected sun exposure. Stay informed, take precautions, and enjoy the beautiful outdoors of Inami while keeping your skin healthy!
As the day unfolds, the UV Index (UVI) reaches its peak around noon, soaring to a significant 12. Starting from a modest 2 at 7:00 AM, the intensity gradually escalates, hitting 4 by 8:00 AM and 6 by 9:00 AM. By 10:00 AM, the sun's rays intensify further, reflecting a 9 on the scale, ultimately culminating in a high of 11 at 11:00 AM.
