Understanding the UV Index in Chungju, South Korea is essential for safeguarding your skin and overall health. With the Dwa climate contributing to varying UV exposure throughout the day, being informed can help you prevent sunburn and long-term skin damage. During peak hours, particularly between 10 AM and 1 PM, the UV Index soars, reaching levels as high as 12, which signals a need for protective measures. By staying aware of these fluctuating UV levels, you can enjoy the beautiful sunny days of Chungju while keeping your skin safe and healthy.
The UV Index throughout the day reveals a notable peak of intensity around midday. Starting from a gentle 1 at 07:00, the index rises gradually to reach 3 by 08:00. As the sun climbs higher, things heat up quickly, with values soaring to 5 at 09:00 and then sharply escalating to a maximum of 12 by 12:00. This potent level of UV exposure is sustained until 13:00, when it slightly dips to 11. The afternoon brings a gradual decline, with readings of 10 at 14:00, 7 at 15:00, and slipping further to 5 at 16:00. As the sun begins to set, the UV Index dwindles back down to 2 at 17:00 and settles at a safer 1 by 18:00 and 19:00. It's a clear reminder to protect your skin during those peak hours!
