Understanding the UV Index is crucial for residents of Clinton Township, as it provides essential information about the sun's intensity and the potential risks associated with UV exposure. Being aware of the UV levels helps in preventing sunburn and maintaining skin health, particularly during the summer months when the index can reach a peak of 10 around midday. In this Dfa climate zone, where hot summers can lead to elevated UV risks, knowing when to seek shade or apply sunscreen is vital for protecting yourself from harmful effects. Stay informed and enjoy the sunny days safely!
The UV Index throughout the day presents a dynamic picture of sun intensity. Starting off gently, the morning hours at 07:00 and 08:00 register a low index of 1, perfect for early risers. As the sun climbs higher, the UV index rises sharply, hitting 4 by 10:00 and peaking at a striking 10 between 13:00 and 14:00—an indicator of potential harm to unprotected skin. After this zenith, the UV levels begin to gracefully descend, settling back to 4 by 17:00 and tapering down to 1 again by 19:00. It’s a vivid reminder that while midday sun can be inviting, protection is essential during peak hours.
