Understanding the UV Index in Ponta Grossa, Brazil is essential for protecting your skin and maintaining overall health. High UV levels, especially between 10 AM and 2 PM, can significantly increase the risk of sunburn and long-term skin damage. Ponta Grossa's Cfa climate, characterized by its warm summers and moderate sunshine, presents unique challenges when it comes to UV exposure. By staying informed about the daily UV Index, you can make smarter choices about sun protection and enjoy the beautiful outdoors safely.
The UV Index highlights a dynamic shift in sun exposure throughout the day. Starting off at a modest level of 1 at 07:00 and 08:00, the intensity gradually increases, peaking at 7 from 12:00 to 13:00, indicating high risk for harm from unprotected sun exposure.

As spring transitions into summer, the index drops slightly in May to 8 (very high), allowing for a longer burn time of 15 minutes. However, during June and July, the index remains high at 6 and 7, respectively, granting 25 minutes of exposure before burning occurs.
