Understanding the UV Index is crucial for residents of Thedford, United States, as it plays a significant role in sun safety and skin health. The UV Index measures the strength of ultraviolet (UV) radiation from the sun, helping you gauge the potential risk of sunburn when outdoors. With Thedford's climate classified as Dfa, which features warm summers, the UV exposure can peak significantly—especially around midday, where levels can reach as high as 10. Being aware of these fluctuations can empower you to take necessary precautions for sun protection, ensuring your days in the sun are enjoyable and safe.
The UV Index shows a dynamic range throughout the day, starting low in the morning with values of 1 at 07:00 and 08:00. As the sun climbs higher, the index rises steadily, reaching 2 by 09:00. A noticeable jump occurs around 10:00, when it spikes to 4, but it’s not until 11:00 that we hit a peak of 7. The intensity soars to a maximum of 10 at both 13:00 and 14:00, urging everyone to take precautions against harmful UV rays.
