Understanding the UV Index is crucial for residents and visitors in Salto, Argentina, where the warm, humid subtropical climate can lead to elevated sun exposure. With UV levels peaking around midday, being aware of these fluctuations helps to prevent sunburn and supports long-term skin health. During the hottest hours, particularly between 12 PM and 2 PM, the UV Index can reach values as high as 5, signifying a moderate risk of harm from unprotected sun exposure. By knowing the UV Index, you can better protect yourself and enjoy the beautiful sunny days in Salto with confidence!
The UV Index data for the day paints a clear picture of sun intensity as the hours progress. Starting at 07:00, the index is at a comfortable 0, allowing for a worry-free morning.

This gradual increase peaks at 12:00 and 13:00, reaching a maximum of 5, indicating that sun protection is a must during these hours.
