Understanding the UV Index is crucial for residents and visitors in Si Mahosot, Thailand, where the tropical climate can expose individuals to high ultraviolet radiation levels. The UV Index provides a vital gauge of solar UV intensity throughout the day, particularly peaking between 10:00 AM and 2:00 PM when values reach up to 14, indicating severe potential for skin damage. By being aware of these levels, you can effectively protect yourself from painful sunburns and long-term skin health issues. With Si Mahosot's predominantly warm weather, understanding UV risks becomes an essential part of ensuring safe outdoor activities under the sun. Stay informed, stay protected!
As the sun rises, the UV Index begins its steady climb, starting at a mild 1 by 7:00 AM. By 8:00 AM, it nudges up to 3, signaling the need for some caution. The intensity reaches a notable 6 by 9:00 AM, but it’s from 10:00 AM to 12:00 PM when the sun truly asserts its power, peaking at a scorching 14 at noon. Fortunately, the index starts to dip slightly, maintaining a robust 10 at 2:00 PM before gradually descending to a 1 by late afternoon. As daylight wanes, the UV Index drops to 0 by 7:00 PM, bringing a welcome relief as the day comes to a close. Stay sun-smart and protect your skin during those peak hours!
