As a region with a Cfa climate, residents and visitors are frequently exposed to varying levels of ultraviolet radiation—particularly during peak hours from 10 AM to 2 PM, when the index soars to 12 and above. By staying informed about the UV levels throughout the day, you can take appropriate protective measures to enjoy the sun safely while minimizing risks associated with excessive exposure.
