In Newport, United States, being aware of the UV Index is crucial for protecting your skin from harmful solar radiation. Understanding UV levels can significantly aid in sunburn prevention and maintaining overall skin health—especially in a city that experiences varied seasonal climates within the Dfb zone. With peak UV values reaching 10 around midday, it's essential to stay informed about daily exposure risks. Whether you're soaking up the sun on the beach or enjoying outdoor activities, keeping an eye on the UV Index can help you make smarter choices for your skin and well-being.
At sunrise, the UV Index starts at a gentle 1 at 7:00 AM, ideal for early risers. As the day progresses, the sun climbs higher, pushing the index to 3 by 8:00 AM, and reaching a moderate 5 by 9:00 AM. 10:00 AM marks a turning point with a significant jump to 7, and by 11:00 AM, it peaks at an impressive 9. The intensity continues to soar, hitting a maximum of 10 from 12:00 PM to 1:00 PM, signaling the highest risk for sun exposure. As the afternoon unfolds, the index begins to taper off, dropping to 8 at 2:00 PM, and further declining to 5 by 4:00 PM. As day transitions into evening, the UV Index gradually recedes, settling back to 1 by 7:00 PM. It's crucial to stay protected during those peak hours between 10:00 AM and 2:00 PM when the sun's rays are strongest!

May and June stand out as the months with the highest risk, featuring very high UV Index values of 9 and 10, respectively, allowing for a burn time as short as 15 minutes. From April to August, the UV exposure is particularly concerning, with values of 7 or more, categorizing these months as high to very high risk for skin damage. Visitors and residents are strongly advised to take precautions during these months, such as wearing protective clothing, using broad-spectrum sunscreen, and seeking shade, especially during midday hours when UV radiation is at its peak.
