Understanding the UV Index is crucial for residents and visitors of Terra Santa, Brazil, as it plays a vital role in preventing sunburn and safeguarding skin health. With its tropical climate and high UV exposure, especially during midday hours, being aware of UV levels can help everyone make informed decisions about sun protection. For instance, during peak sun hours, the UV Index can soar to a level of 11, which poses a significant risk for skin damage. By paying attention to these values, you can enjoy the beautiful Brazilian sun while keeping your skin healthy and protected.
The UV Index today tells a compelling story of the sun's intensity as the day unfolds. Starting off gently at 07:00 and 08:00 with a safe index of 1, the sun gradually rises in strength. By 09:00, it climbs to 3, hinting at the heat to come. The real surge happens between 10:00 and 13:00, where it peaks at a blistering 11. It's crucial to stay protected during this peak time! As the afternoon progresses, the UV Index begins to decline, dropping to 10 by 14:00 and then tapering off to 7 at 15:00. The evening brings a comforting return to lower levels, settling at 1 by 18:00 and ultimately 0 after sunset at 19:00. Stay safe and enjoy the sun, but remember to shield yourself during those midday hours!
