Understanding the UV Index in Chunghwa, North Korea is crucial for protecting your skin and overall health. With varying UV levels throughout the day, awareness can significantly help in preventing sunburns and reducing long-term skin damage. Chunghwa's Dwa climate often sees high UV exposure, particularly around midday when the index peaks at a formidable 10. Being informed about these levels allows residents and visitors alike to make better decisions about sun safety and enjoy the beautiful surroundings without compromising their skin health.
As the day unfolds, the UV Index paints a vivid picture of sun exposure. Starting at a modest 1 by 07:00, the index steadily climbs to 3 by 08:00, marking the beginning of a sun-filled day. The real surge occurs at 10:00, where it reaches 7, peaking at an intense 10 between 12:00 and 13:00—the highest point of the day. Afterward, a gradual decline begins, with values dropping to 9 at 14:00, and easing down to 4 by 16:00. As evening approaches, the index settles back to a comfortable 1 by 18:00, allowing for a safe close to sunlit hours. Be sure to protect your skin during those peak hours!

As the seasons change, so do the UV index levels and associated risks for skin damage. During the winter months of January to February, the UV index remains moderate (3-4), allowing for a 30-minute burn time. However, starting in March, the UV index escalates to high (6), indicating the need for increased sun protection. The high-risk months peak from April to August, with the UV index reaching very high (8-10) and even extreme levels (11) in August, where burn times drop to just 10 minutes. September sees a decline to very high (9), while October returns to high levels (6) with a longer burn time of 25 minutes. As winter returns in November and December, the sun's strength diminishes, with indexes dropping to moderate and low (4 and 2), leading to safer burn times of 30 and 45 minutes, respectively. It is crucial for visitors and residents to use sun protection consistently during high-risk months and limit direct sun exposure, especially during midday hours.
