In Frutal, Brazil, being aware of the UV Index is essential for safeguarding your skin from harmful sun exposure. Understanding UV levels is crucial not only for preventing painful sunburns but also for maintaining long-term skin health. With a climate characterized by hot summers and significant UV intensity, particularly between 10 AM and 2 PM when levels can peak at 7, residents and visitors must stay informed. Embracing this knowledge empowers you to enjoy the sunny days while minimizing the risks associated with ultraviolet radiation.
The UV Index exhibits a dynamic pattern throughout the day, peaking sharply around midday. Starting off mild at 07:00 and 08:00 with a UV Index of 1, exposure remains minimal. However, as the sun climbs, the intensity increases significantly by 09:00, reaching 3, and continues to rise to a notable peak of 7 at 12:00 and 13:00. This indicates a need for sun protection during these hours. By 14:00, the UV Index begins to decline, falling to 5, and subsequently drops further, settling at 1 by 17:00 and finally reaching 0 by 18:00. In summary, the day's UV exposure highlights the importance of vigilance against UV radiation, particularly between 10:00 and 14:00 when the sun’s rays are at their strongest.

The UV Index experiences significant fluctuations throughout the year, with extreme levels persisting from January to April, where the UV Index remains consistently 16-13 and burn times are as short as 10 minutes. May marks the beginning of a decrease, dropping to a very high index of 9 with burn times extending to 15 minutes, a brief respite before the summer months. The UV levels become high in June (index 7), but by July, they spike again to very high at 8, alongside August which also sees an extreme index of 11. From September to November, the UV levels return to the extreme category, peaking again at 14, making these months high-risk for skin damage. As a result, visitors and residents should take extra precautions, especially from January to April and during the late summer into fall (August to November), ensuring proper skin protection through sunscreen, appropriate clothing, and limiting direct sun exposure during peak hours.
