Understanding the UV Index is essential for the residents of Espirito Santo do Pinhal, Brazil, where the climate's warm and temperate conditions can lead to significant sun exposure throughout the year. Awareness of UV levels is crucial for preventing sunburn and promoting long-term skin health, as elevated UV values—especially the peak readings around midday—indicate a higher risk for skin damage. With the UV Index peaking at 7 during the sunniest hours, it's important for the community to stay informed about daily UV fluctuations, ensuring safe sun practices amidst the beautiful landscapes of this vibrant region.
At dawn, the UV Index starts off low, with a maximum of 1 at 07:00 and 08:00. As the sun rises higher, it reaches 3 by 09:00, before climbing to a peak of 7 at 12:00. This midday intensity signifies a need for sun protection, especially during the height of the day when UV exposure is most potent. The index begins to decline in the afternoon, dropping to 5 at 14:00 and settling back to 1 by 17:00. By 18:00 and into the evening, the UV Index sharply drops to 0, marking a safe time to enjoy outdoor activities without the risk of sunburn. Stay sun-safe!

The UV Index shows significant seasonal variation, with the highest readings occurring from January to April, where the index reaches an extreme 16. These months pose a high risk for sunburn, with a critical 10-minute burn time. After April, the index slightly decreases, but remains very high in May (8) and July (8), and high in June (7). As summer transitions into fall, the UV Index fluctuates but remains concerning, especially in September (12) and October (14), both categorized as extreme, again allowing only a short 10-minute exposure without protection.
