In Kamo, Japan, staying aware of the UV Index is crucial for protecting your skin and overall health. The UV Index provides valuable information about the strength of ultraviolet radiation, which can lead to sunburn and long-term skin damage if not properly managed. Kamo experiences a Cfa climate, meaning hot summers and moderate humidity, which can amplify UV exposure, particularly during peak hours from 11 AM to 1 PM when the index reaches a maximum of 11. Understanding these UV levels allows residents and visitors to take proactive measures to shield themselves from harmful effects, ensuring safe and enjoyable outdoor activities.
The UV Index exhibits a dynamic pattern throughout the day, peaking impressively at 12:00 PM with a striking value of 11, indicating a very high risk of harm from unprotected sun exposure.

With these fluctuations, it’s crucial to be sun-smart, especially during peak hours!
