In Sao Domingos do Prata, understanding the UV Index is crucial for protecting your skin and ensuring long-term health. With the region's tropical climate, the sun can be particularly intense, particularly around midday when UV levels peak at a significant 8. Awareness of these UV levels not only helps in preventing painful sunburns but also plays a vital role in mitigating long-term skin damage and health risks. By staying informed about daily UV exposure, residents can enjoy the sun safely while safeguarding their skin against potential harm.
The UV Index throughout the day displays a notable peak in intensity between 12:00 PM and 1:00 PM, reaching a maximum of 8—a clear signal for sun safety. As the morning unfolds, the index rises steadily from 1 at 7:00 AM to an impactful 7 by 11:00 AM. Following the midday zenith, the UV readings begin to decline, gently tapering to a 5 at 2:00 PM, and further dropping to a mere 1 by 4:00 PM. As evening approaches, UV exposure diminishes gradually to 0 by 6:00 PM—encouraging late-day strollers to bask in diminishing rays without worry. This pattern underscores the importance of sun protection when the UV Index peaks during midday hours.
