In Itapeva, Brazil, staying aware of the UV Index is crucial for protecting your skin and overall health. Understanding UV levels helps you prevent sunburn and reduces the risk of long-term skin damage, especially in a region known for its Cfa climate, which often brings intense sunlight. During the day, UV levels can peak as high as 6 around midday, meaning that even short exposure could lead to harmful effects. Being informed empowers you to enjoy the sunshine safely while prioritizing your well-being.
As the day unfolds, the UV Index begins to rise, peaking sharply around midday. From a gentle 1 at 7 AM, it escalates to a moderate 6 between 11 AM and 1 PM, signaling peak sun exposure. During these crucial hours, it's essential to protect your skin with sunscreen and wear appropriate clothing. As the afternoon progresses, the intensity wanes, dropping to 4 at 2 PM and further declining to 3 by 3 PM. By 4 PM, it returns to a safe 1, and finally settles to 0 after sunset, making late afternoon and evening hours ideal for outdoor activities without the risk of UV damage. Stay informed and enjoy the sun responsibly!

Throughout the year, UV Index levels show significant seasonal variation, with the most intense exposure occurring from November to April, when values reach extreme levels of 15 or higher, making these the highest-risk months for UV exposure. Specifically, January, February, March, and December record a UV Index of 15 or 16, while October displays a UV Index of 14. During these months, a burn time of just 10 minutes is enough to risk skin damage. From May to July, the exposure decreases to 'very high' and 'high' levels, but caution is still advised, especially in May and August when the burn times decrease to 15 minutes. Visitors and residents should take proactive measures against sun exposure by employing broad-spectrum sunscreen, wearing protective clothing, and seeking shade during peak UV hours, particularly from 11 a.m. to 4 p.m.
