In Planaltina, Brazil, being aware of the UV Index is crucial for safeguarding your skin against harmful sun exposure. Understanding UV levels is essential for sunburn prevention and maintaining long-term skin health, especially in this region characterized by a tropical savannah climate (Aw) where the sun can be particularly intense. During peak hours, such as between 11:00 AM and 1:00 PM, the UV Index can soar to 10, indicating a very high risk of harm from unprotected sun exposure. Knowing how to protect yourself in these hot hours can make all the difference in enjoying the beautiful sunny days of Planaltina while keeping your skin healthy and protected.

As the sun reaches its zenith, caution is advised for outdoor activities during the 11:00 AM to 1:00 PM window when the index remains high at 9 and 10. Following this midday surge, the index gracefully descends; by 3:00 PM, it dips to 4 and continues to decline to 1 by 5:00 PM.
