Understanding the UV Index in Mendoza, Argentina, is crucial for safeguarding your skin. Awareness of UV levels helps you prevent sunburn and promotes long-term skin health, making it essential for both residents and visitors alike. With Mendoza's semi-arid BWk climate, the risk of harmful UV radiation is significant, especially during the peak daytime hours when the UV Index can reach levels of 4. This means it's vital to stay informed and take protective measures when venturing outdoors, ensuring that your time in the sun is both enjoyable and safe.
Today’s UV Index reveals a gradual ascent in sun intensity as the day unfolds. Starting from 0 at 07:00 and 08:00, the UVI picks up momentum, reaching 1 by 09:00 and 10:00. The peak occurs between 12:00 and 14:00, with a maximum of 4—an ideal time for sun safety awareness! As the afternoon transitions to evening, the index declines to 3 at 15:00 and dips back to 1 by 17:00 and 18:00, before finally resting at 0 by 19:00. Plan your outdoor activities wisely, especially during those peak hours!
