In Paranaguá, Brazil, understanding the UV Index is crucial for safeguarding your skin and overall health. With its humid subtropical climate (Cfa), this coastal city witnesses varying UV levels throughout the day, peaking around midday when exposure can lead to sunburn and long-term skin damage. By being aware of the UV Index, particularly when it reaches levels of 6 between noon and 2 PM, residents and visitors can take proactive measures to protect themselves—ensuring vibrant skin health while enjoying the sunny Brazilian outdoors.🌞
Throughout the day, the UV Index escalates to its peak between 12:00 PM and 1:00 PM, reaching a high of 6—a clear indicator to stay protected from the sun's rays. Early morning hours see a gentle start, with a maximum 1 at 7:00 AM and 8:00 AM, gradually rising to 2 by 9:00 AM. As the sun climbs, so does the intensity, spiking to 5 at 11:00 AM and maintaining a steady 6 for the peak hours. Following this brief burst of intensity, the UV Index dwindles swiftly, dropping to 4 by 2:00 PM, then further decreasing to 3 at 3:00 PM, and tapering off to 1 by 4:00 PM. Finally, as daylight fades, the index plummets to 0 by 6:00 PM, marking the end of a vibrant, sunlit day. Remember to stay safe and protect your skin, especially during midday hours!
