Understanding the UV Index in Quy Chau, Vietnam, is crucial for safeguarding your skin and health. With its Cwa climate, characterized by distinct wet and dry seasons, the sun can be deceptively intense, especially during midday hours when UV levels reach a staggering 14. Awareness of the UV Index not only helps in preventing painful sunburns but also plays a significant role in reducing the risk of long-term skin damage. By staying informed about UV exposure risks throughout the day, residents and visitors can enjoy the region's beauty while keeping their skin safe.
As the sun rises, the UV Index gradually climbs, starting at a mild 2 at 7:00 AM. By 8:00 AM, it ramps up to 4, signaling an increase in sun intensity. The midday hours see the UV Index peak dramatically, hitting a scorching 14 at both 11:00 AM and 12:00 PM, a clear call for sun safety. As the afternoon unfolds, it dips slightly to 13 at 1:00 PM and then gradually decreases to 10 by 2:00 PM. By the late afternoon, the index falls to 4 at 4:00 PM and drops further to 1 by 5:00 PM, finally reaching 0 by 7:00 PM. This data serves as a reminder to take advantage of the early hours while staying protected when the sun is at its strongest.
