Understanding the UV Index is crucial for residents and visitors in Nong Kung Si, Thailand, a region known for its warm, tropical climate. As the sun climbs higher in the sky, UV levels can reach dangerously high points, peaking at 15 around noon. This makes awareness of UV exposure vital for sunburn prevention and long-term skin health. With daily fluctuations in UV intensity, particularly from 08:00 to 14:00, it's essential to stay informed about local conditions to protect your skin and enjoy the beautiful Thai outdoors safely. Whether lounging under the sun or engaging in outdoor activities, knowing the UV Index helps you take necessary precautions against harmful effects.
The UV Index shows a dramatic rise in solar intensity as the morning progresses. Starting at a mere 1 at 07:00, the index climbs steadily, reaching a peak of 15 by noon. As the sun reaches its zenith, from 11:00 to 13:00, it's crucial to take precautions against harmful UV rays, particularly when the index hits 13 and 14. However, relief comes in the afternoon as it begins to dip to 11 at 14:00, eventually dropping to 4 by 16:00 and plummeting to 0 by 19:00. This data highlights the importance of sun safety during the height of the day, especially when the UV Index is at its highest. Stay sun-smart!
