In DuPont, United States, staying informed about the UV Index is crucial for safeguarding your skin against harmful ultraviolet rays. Understanding UV levels is essential not just for preventing painful sunburns but also for maintaining overall skin health in the long run. With a Csb climate, residents experience unique UV exposure risks throughout the year, particularly during peak hours when the index can reach as high as 9 around midday. By keeping an eye on the UV Index, you can enjoy the sun safely while protecting your skin from its potential harm.
The UV Index today shows a dynamic rise and fall throughout the hours, peaking in the midday sun. Starting from a gentle 1 at 07:00, it gradually climbs to reach 8 by 12:00, just before the sun reaches its zenith. The intensity spikes to its highest point of 9 at 13:00, remaining high until 14:00, when it begins to taper off. By 15:00, it drops to 7, continuing its downward trend to 4 by 17:00, and then easing back to the safer 1 by 19:00. Remember to protect yourself during the peak hours, especially between 11:00 and 14:00, when the sun’s rays are strongest!
