Understanding the UV Index in Cruzeiro, Brazil, is crucial for protecting your skin from harmful solar radiation. Monitoring these levels not only aids in preventing painful sunburns but also plays a key role in maintaining long-term skin health. With a Cfb climate that brings warm summers and mild winters, Cruzeiro experiences varying UV exposures throughout the day. During peak hours, particularly between 10 AM and 2 PM, the UV Index can reach 7, indicating a high risk of harm from unprotected sun exposure. Being aware of these values empowers you to enjoy the sun safely while minimizing health risks.

The early afternoon maintains a respectable UV level of 6 at 1:00 PM before gradually tapering off. By mid-afternoon, it drops to 4, then swiftly declines to 1 by 4:00 PM, and finally settles at 0 by 6:00 PM, marking the day's end for UV concern. This hourly trend underscores the importance of sun safety during peak hours, especially between 10 AM and 2 PM.
