Awareness of the UV Index in Grosse Pointe Park is essential for protecting your skin and overall health. Understanding UV levels is crucial in preventing sunburn and reducing the risk of skin damage, especially during the warmer months. With a climate categorized as Dfa, residents are often exposed to varying UV levels, peaking around midday with values reaching up to 10. This highlights the importance of staying informed about daily UV exposure risks to enjoy the outdoors safely and effectively.
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.

Throughout the year, the UV Index experiences significant fluctuations, particularly peaking in the summer months. From April to August, visitors and residents should be especially vigilant as the UV Index reaches levels classified as very high (9-10), with minimal burn times of only 15 minutes. The highest risk months are June and July, which demand strict sun protection measures. Conversely, the winter months of January and December present lower UV exposure (Index 2), allowing for longer safe sun exposure—45 minutes before burning occurs. To protect against harmful UV rays, it is advisable for everyone to wear sunscreen, seek shade, and wear protective clothing, especially during high-risk months.
