In Moita Bonita, Brazil, understanding the UV Index is crucial for protecting yourself against the harmful effects of sun exposure. With peak UV levels reaching as high as 12 during midday, awareness of these rates is essential for preventing sunburn and promoting long-term skin health.

The intensity continues to dominate until 12:00 PM, when it slightly dips to 11 but remains a major concern. As afternoon approaches, the UV Index gradually descends from 9 at 1:00 PM to 6 by 2:00 PM, before more noticeable declines occur, settling at 3 by 3:00 PM. The evening brings a steady reduction, with readings plummeting to 1 by 4:00 PM and 5:00 PM, and finally dropping to zero after 6:00 PM.
